CTRIO FAQ0002
16-Nov-2015
Q: What causes the CTRIO/CTRIO2 to sometimes get double counts or be sensitive to noise?
A: If the CTRIO/CTRIO2 is counting double it is seeing double edges. Use an oscilloscope to verify the signal. Spurious counting can be caused by:

• The input signal being differential (i.e. traversing both sides of ground (M)
• The input signal is dirty (i.e. electrically noisy).
  

Things to consider:

1. Use the shortest distance possible for wiring.
2. Use shielded cabling.
3. Use good routing practices (don't run signal wire parallel to high voltage, or near electrically noisy devices).
4. Isolate the "M" terminal of CTRIO/CTRIO2 so that it is not common with higher current devices (i.e. a 2mA current in "M" leg can cause a false ON state).
5. Use bipolar sensor outputs (i.e. totem-pole / push-pull).
6. If using a CTRIO2 you can edit the Input Filter values to filter out unwanted noise:
1. If using Do-more PLC: From the menu, PLC --> System Configuration... --> Module Configuration(s), select your CTRIO2, press the <Edit Config> button, then press the <Input Filters...> button.
2. If using Do-more PLC then the Input Filters can also be written to via ladders using the CTREGWR "CTRIO Write Register" instruction.
3. If using a DL-PLC then the only way to write the Input Filter values is via ladders using the CTRRGWR "CTRIO Register Write" IBox. CTRIO Workbench does not yet allow access to these values during configuration.

CTRIO FAQ0004
16-Nov-2015
Q: Can Pulse Profile parameters (e.g. accel/decel) be changed on the fly from ladders?
A: No. However, here are some ideas to possibly solve this:

• Use multiple Pulse Profiles (250+) and then switch between them to obtain different accel/decel settings.
• Create your own "profiles" in the PLC by using the CTRIO/CTRIO2's Velocity Mode function (0x20) to output the different Frequencies and Counts you have calculated to simulate acceleration and deceleration
• If using a Do-more PLC, for example, use the CTRUNVEL "CTRIO Run Velocity Mode" instruction and after enabling it, dynamically update the Frequency parameter as needed.
• If using a DL-PLC, for example, use the CTRVEL2 "CTRIO Velocity Mode 2" IBox and after enabling it, dynamically update the Frequency parameter as needed.
  

CTRIO FAQ0005 (similar to DirectSOFT FAQ109; ERM FAQ0018)
08-Jul-2002
Q: While installing CTRIO Workbench various problems are encountered.
A: Although installation problems are uncommon the following errors have been seen:

• (1) "Unable to load INSTCTR.DLL"
     Suggested solutions:
  - You are trying to install CTRIO Workbench v2.x onto a Win95 PC. It is not compatible with Win95.
  - You are trying to install CTRIO Workbench v1.x onto a PC that has DirectSOFT v4.x. It is not compatible with that version.
  - You are trying to install CTRIO Workbench onto a Win98 PC that has a system problem. First try installing in the Safe Mode. If this doesn't work you may have to reinstall Win98.
   
• (2) "CTRIO.EXE setup error"
  You are probably trying to install CTRIO Workbench onto Win2K/WinNT/WinXP without Administrator rights to the PC.
   
• (3) "Illegal operation"
  This is usually only encountered when installing on a Win98 PC. Installing in Safe Mode usually fixes this.
   
• (4) PC appears to lock up.
  The PC probably did not lock up. For some reason sometimes during the install procedure the install will pop up a dialog and wait for your response. The window that has this dialog sometimes loses focus and gets hidden behind other windows that may be open. Therefore try pressing the ALT-TAB, switching to each open window and then minimizing it thus looking for the dialog that might be behind. This usually works and when the dialog is found, simply press the <OK> button and the install will continue.

CTRIO FAQ0006
21-May-2002
Q: Have CTRIO configured for Count Capture. When I get a pulse for capture on Input D the count is captured properly. However when I get a Reset on Input C not only is the current count cleared (as expected), the captured count is also cleared!
A: There are two ways in which a Reset can occur. (1) Hardware Reset with Input C; (2) Software Reset with Reset Bit from PLC. Formerly the Hardware Reset did indeed behave this way. It would clear both the Current Count and the Captured Count. The Software Reset however, only cleared the Current Count and left the Captured Count intact. However, for consistency purposes (and some other reasons) we changed the behavior of the Hardware Reset to be identical to that of the Software Reset with regards to the clearing of the Capture Count. This behavior was changed in H2-CTRIO firmware version v2.1.7. See below for Timing diagrams.

CTRIO FAQ0007
16-Nov-2015
Q: Are there examples of each of the CTRIO/CTRIO2 functions using DL-PLC?
A: The manual describes them, and there are several example programs and configuration files under the HAPTools\CTRIO and \HAPTools\CTRIOwb2 folders. However, it is highly recommended you use the Do-more PLC or at least use the CTRIO IBox instructions in the DL-PLC. Using the CTRIO/CTRIO2 using discrete DL instructions is very tedious and prone to error.

CTRIO FAQ0008 (see also DirectSOFT FAQ0224)
26-Sep-2017
Q: Encountering various problems when starting up CTRIO Workbench:
A: Here are some of the more common problems:

• (1) In CTRIO Workbench the "Scan Time" and "Max Scan Time" fields are blank.
  This means there is an older copy of the DSPLINK.DLL file in the HAPTools folder on your PC. Make sure that at least the April 4, 2002 version of DSPLINK.DLL file is in the DirectSOFT folder and eliminate the one in the HAPTools Folder entirely; it is not needed.
   
• (2) CTRIO Workbench indicates the CTRIO module is in "Startup" mode and all fields are greyed out.
  This indicates the CTRIO Workbench cannot communicate with the CTRIO. The comm issue is not between PC and the PLC, but rather it is between the PLC and the CTRIO in the base (i.e. backplane comms are failing). Some reasons for this are:
  o - The firmware of the DL-PLC, EBC or WinPLC you are using doesn't support the CTRIO:
  
  

  CPU	Firmware	Hardware	Slot
  DL05	v4.60	-	-
  DL06	v1.40	-	Any
  D2-240	v3.22	-	Not slot 0
  D2-250	v1.56	-	Not slot 0
  D2-250-1	v3.5	-	Not slot 0
  D2-260	v1.2	-	Not slot 0
  H2-WPLC	-	xK	Any
  H2-EBC	v2.1.357	-	Prior Rev 9A --> Not slot 0 Rev 9A --> Any
  H2-EBC100	Any	-	Any
  H2-PBC	Any	-	Prior Rev 4A --> Not slot 0 Rev 4A --> Any
  D4-450	April 2000: H8 (CISC) v2.00 SH (RISC) v1.5000 May 2000: H8 (CISC) v2.00 SH (RISC) v2.500	-	Any
  H4-EBC	v2.1.328	v4F	Any
  T1H-EBC	v1.0.444	v2I	Any
  T1H-EBC100	Any	Any	Any
  T1H-PBC	v1.1.10	v2D	Any
  T1K-DEVNETS	v1.80	-	Any
  T1K-MODBUS	v1.80	-	Any

  
  o - The CTRIO has a damaged backplane connector.
  o - The CTRIO is not seated properly in the base (particularly if using DL05, DL06 or DL405).
  o - The CTRIO is in the slot adjacent to the CPU (slot 0) and you are using a D2-240, 250 or 260 CPU. Move it to another slot.
  o - You are using CTRIO Workbench v1.1 with a CTRIO that has firmware version 2.0.1 or later. Update your Workbench.
  o - You are using CTRIO Workbench v1.1 and starting it from DirectSOFT. Either start it from DS Launch or upgrade CTRIO and Workbench.
  o - The PLC has old firmware. The Product Advisory details the revision levels required.
  o - The PLC power is OFF.
  o - You have a DL205 in a "-1" base and you have an H2-EBC, H2-WinPLC or H2-PBC that is incompatible with the newer "-1" bases. (If you have an older EBC, PBC or WinPLC, you must either RMA them back to Automation Direct for upgrade, or send them to us (Host Engineering, Inc).
       Hardware requirements for -1 base usage:
            H2-EBC must be 7F, 8F or later.
            H2-EBC-F must be 1F or later.
            H2-WPLC1, WPLC2 must be 4K, 5K or 6K or later.
            H2-WPLC3 must be 1K or later.
            H2-PBC must be 2D or later.
            (NOTE: "7F" meaning - "7" is bare board revision. "F" is the revision of the assembly drawing.)
   
• (3) DS Launch does not display the CTRIO Workbench 2 startup options.
  For DS Launch to display these startup selections on its menu you must have at least DirectSOFT v4.0 Build 18 or later.
   
• (4) In DirectSOFT (PLC --> Tools) there are multiple listings of CTRIO and ERM Workbench.
  We're not sure how this happens. But the options are setup in the Windows Registry. To remove them manually it is required that changes be made directly to the Registry. This is not recommended for the normal user! And on some PCs the Administrator does not permit it. However, if you dare:
  1.  Select Start --> Run...
  2.  Type in regedit and press the <OK> button.
  3.  Open HKEY_LOCAL_MACHINE folder.
  4.  Open SOFTWARE folder.
  5.  Open Host Engineering, Inc. folder.
  6.  Click on the HAPTools folder.
  
  Now in the right window you will see five strings values:
  
  (Default)    REG_SZ   (value not set)
  a                REG_SZ   CTRIO Workbench2;;CTRIO configuration utility;;C:\HAPTools\CTRIOwb2.EXE
  b                REG_SZ   ERM Workbench;;Ethernet Remote Master Workbench configuration utility;;C:\HAPTools\ERMWB.EXE
  InstallList    REG_SZ   ab
  NextInstall  REG_SZ   c
  
  To remove them completely right-click on a, b, InstallList and NextInstall one at a time and delete them. The only string value that should remain is (Default).
  
  If you are plagued by multiple menu selections, then just make the registry entries look exactly like the above.
   
• (5) In DirectSOFT selecting PLC --> Tools causes PC to lock up.
  We have found this to sometimes happen in versions earlier than v4.0 Build 18, when you have installed CTRIO Workbench and/or ERM Workbench under a different folder other than from c:\HAPTools. To fix:
  1. Uninstall CTRIO Workbench & ERM Workbench (Start --> Programs --> AutomationDirect Tools --> Uninstall).
  2. Reinstall CTRIO Workbench & ERM Workbench with the default folder (c:\HAPTools). To do this run the DirectSOFT install, but select the <Custom> install button and uncheck everything except CTRIO Workbench & ERM Workbench. In other words, you probably don't need (or want) to reinstall DirectSOFT, but merely the Workbenches.
      
• (6) Get "Error reading Shared RAM!"
  This means that the CTRIO cannot read/write to the PLC across the backplane. This is commonly caused by one of the following:
  
  - You are trying to connect to a CTRIO via DCM, ECOM or serial connection and you have selected DirectNET protocol. You must use K-sequence protocol. Or for the ECOM you can also use ECOM protocol (recommended).
  - You are trying to connect to a CTRIO that is installed in a PLC rack whose CPU has a password and it has not been unlocked by DirectSOFT. To fix you must connect with DirectSOFT and enter the password.
  - Try reseating the CTRIO or trying a different slot.
  - The slot, backplane, CPU or CTRIO is defective. Replace.
   
• (7) Get "Error reading configuration"
  This means that CTRIO workbench is not getting enough of the PLC's time to upload the CTRIO configuration across the backplane. This is commonly caused by the PLC being too busy with other comms. This can be confirmed by switching the PLC to STOP and then back to TERM (this will take it out of RUN mode!), and then trying again. If it works, then this is confirmation.
   
• (8) Get "Unable to load DSPLink.DLL"
  This basically means the CTRIO Workbench you are using is incompatible with the CommServer (i.e. DirectSOFT) you are running. Some history:
  - The DSPLink.DLL file is used by CTRIO Workbench v1.x and for CTRIO modules with firmware v1.x.x.
  - The DSPLink2.DLL file is used by CTRIO Workbench v2.x and for CTRIO modules with firmware v2.x.x.
  - There have been 4 DSPLink files over our history:
            (1)  DSPLink.DLL - Original for CTRIO Workbench v1.x
            (2)  DSPLink.DLL - Broken one dated 25-Mar-2002 for CTRIO Workbench v1.x.
            (3)  DSPLink.DLL - Fixed one dated 04-Apr-2002 (or later) for CTRIO Workbench v1.x
            (4)  DSPLink2.DLL - Original for CTRIO Workbench v2.x.
  SOLUTIONS:
            - Upgrade your CTRIO Workbench to at least v2.1, or...
            - Downgrade your DirectSOFT to at least v3.0.
  
  
• (9) Get "This application has failed to start because its side by side configuration is incorrect"
  Try one of the following:
  - Rerun the installation by right-clicking on the installation .EXE and choosing "Run As Administrator", or...
  - Download vcredist_x86.EXE file from the Internet and run it. This will update your Windows OS with Microsoft Visual C++ Redistributable package (see http://www.microsoft.com/en-us/download/details.aspx?id=26368)

17-Nov-2015
Q: When trying to connect to CTRIO/CTRIO2 in WinPLC or EBC/EBC100 base with CTRIO Workbench, getting "Error reading base definition".
A: This is usually caused by the CTRIO Workbench not having enough of the backplane bandwidth to complete a connection. Thus, depending on what type of base the CTRIO/CTRIO2 is installed in:

     If WinPLC:  Try stopping the WinPLC's application from running; then try CTRIO Workbench again.

     If EBC/EBC100: Try stopping the master that is currently polling, or disconnect from the master altogether; then try CTRIO Workbench again.

     If none of this works, try reinstalling CTRIO Workbench. There have been instances where something on the PC has corrupted the installation and caused this very error message.

17-Nov-2015
Q: Is it possible to utilize the CTRIO System Functions everywhere the CTRIO/CTRIO2 can be installed?
A: In firmware v2.x System Functions were added to the CTRIO products (H0-, H2-, H4- and T1H-CTRIO) and are present in all CTRIO2 modules. These System Functions allow the writing (and reading) of various internal registers of the CTRIO/CTRIO2. The following table shows what scenarios that these System Functions can be used and how to use them:

(1) - Mapped to the CTRIO/CTRIO2 device structure members
(2) - Use the CTREGWR & CTREGRD instructions (can only read/write one register at a time)
(3) - Mapped to V-memory as configured in the CTRIO/CTRIO2 using CTRIO Workbench
(4) - Use the CTRRGWR & CTRRGRD IBox instructions (can only read/write one register at a time)
(5) - CTRIO/CTRIO2 will not work in local expansion bases
(6) - No way to tell the ERM/ERM100 to access the Shared RAM of CTRIO/CTRIO2 in EBC/EBC100 base
(7) - Mapped to memory as configured in Think&Do
(8) - Use Shared RAM Operations for CTRIO/CTRIO2 in a CALL block
(9) - Mapped as shown with NetEdit3 Show Base Contents
(10) - Use HEIWriteSharedRAM & HEIReadSharedRAM routines

CTRIO FAQ0014 (see also WinPLC FAQ0013, EBC FAQ0030)
17-Nov-2015
Q: What is the expected hit on the scan time for adding an H2-CTRIO/CTRIO2 to WinPLC or EBC/EBC100 rack? When connected with Entivity and adding more than one H2-CTRIO/CTRIO2 I get a timeout.
A: This is different for each product:

For WinPLC, there could be a detectable hit (however, small) simply because it has a comparatively slower processor (100MHz).

On the EBC/EBC100 itself, the addition of a CTRIO will probably not be noticeable at all simply because the EBC/EBC100 has only one thing to do . . . update its I/O.

On a Think&Do or Entivity application there will be about 7ms per CTRIO/CTRIO2 hit due to the number of tags that are created to handle the extra I/O scanning of the CTRIO/CTRIO2 from the PC. Thus, in the Connectivity Center of this software, under "Attributes" you must increase the "Timeout Value for Retries(ms)" value accordingly.

CTRIO FAQ0015
17-Nov-2015
Q: If running velocity mode, can the number of pulses that have been output be read?
A: Yes.

- If using a DL-PLC then use the CTRRGRD "CTRIO Register Read" IBox and select the proper "Position" register.
- If using a Do-more PLC then use the CTREGRD "CTRIO Read Register" instruction and select the proper "Position" register.

CTRIO FAQ0016 (see also WinPLC FAQ0007)
17-Nov-2015
Q: Is there a way to change the preset values in multiple Preset Tables from WinPLC to CTRIO on the fly?
A: Basically there are two choices to do this with CTRIO/CTRIO2:

• Make a Preset Table that turns on an output and use the "0x15 - Edit Entry / Reload" command to change the preset value in this table when needed
• Configure multiple Preset Tables (there are 256 tables available) with different preset values and using the "0x10 - Load Table" command to load the different ones when needed.

CTRIO FAQ0017
17-Nov-2015
Q: Can the CTRIO/CTRIO2 be made to count in both directions (quadrature encoder) but only in a positive range (e.g. 0-499)?
A: Not easily. Here is how it could work:

1. Create a Preset Table to handle the positive direction by making it reset the count to 0 (zero) when it reaches a count of 499.
2. To handle the negative direction, read the count from the CTRIO/CTRIO2 in the PLC for two consecutive scans and compare them. If the count went down between scans, then set a C-bit to indicate a negative direction. As long as the count goes down, keep the bit set.
3. If the count increases, clear the C-bit.
4. If the count keeps decreasing and reaches 0 (zero), then write the current count to +499.
• If using a DL-PLC use the CTRRGRD "CTRIO Register Read" IBox.
• If using a Do-more use the CTREGRD "CTRIO Read Register" instruction.
  

In the above solution, the positive direction would work flawlessly, but the negative direction would be sensitive to the speed at which the encoder is turning along with the speed of the PLC scan. Also, depending on which direction is more critical in your application, you could just as easily make a Preset Table to handle the negative direction and the PLC program to handle the positive direction.

CTRIO FAQ0018
17-Nov-2015
Q: What is the input impedance of the CTRIO/CTRIO2 input?
A: On the input of the CTRIO/CTRIO2 is a JFET (Junction Field Effect Transistor) in a constant-current source arrangement. In this manner it guarantees the input current will be between 5-15mA for the range of 9-30V. So, the input impedance varies based on this characteristic. So at the high voltage extreme:

• 30V input at 15mA = 30/15m = 2KΩ
• 30V input at 5mA = 30/5 = 6KΩ

CTRIO FAQ0019
17-Nov-2015
Q: How does the Pulse Catch function operate? (The manual is a bit unclear).
A: Below is an example timing diagram of the functionality of Pulse Catch with notes at the end explaining. The settings used to generate this diagram are not likely in the real world, but are given here as only an example.

CTRIO Configuration for the diagram:
     - Input C = Pulse Catch
     - Pulse In = Rising Edge
     - Minimum Width In = 300µs
     - Pulse Out Width = 1ms

NOTES:
- The 1st thing to do is to SET the Enable Capture bit. This will cause the CTRIO/CTRIO2 to start looking for the pulse on Input C.
- The 1st pulse is ignored (200µs*) because it doesn't meet the 300µs minimum configured.
- The 2nd pulse is captured (400µs**) because it meets the 300µs minimum configured.
- The 3rd pulse is ignored (400µs***) because though it meets the 300µs minimum configured, it occurs during a capture.
- The Capture Start Bit comes ON as soon as an edge is detected and goes OFF if the pulse does not meet the 300µs minimum. However, it stays ON through the duration of a catch.
- The Output Pulse Bit comes ON as soon as the minimum 300µs minimum is met and stays ON for the Pulse Out Width of 1ms as configured.
- The CTRIO/CTRIO2 Output, if configured for this, will perfectly track the Output Pulse Bit.

Thus, the 2nd pulse is the one that is captured above, and reflected in the 1ms output. In a more practical application, the pulse width would probably be in the <25ms range (as above), but the Pulse Out Width would probably be much longer (e.g. >25ms) so that the PLC would be insured of "seeing" it. 

CTRIO FAQ0020
17-Nov-2015
Q: Is it possible to reset the Preset Table's pointer back to the 1st entry in the Table without resetting the Count or disabling the Output?
A: Yes. The "'round-about" way of doing this is to simply reload the exact same unchanged Preset Table.

• If using DL-PLC use the CTRLDPR "CTRIO Load Profile" IBox.
• If using Do-more PLC use the CTTBLLD "CTRIO Load Table" instruction.

CTRIO FAQ0021
17-Nov-2015
Q: Will the CTRIO/CTRIO2 retain the current count upon power loss? (i.e. Does it have retentive count capability?)
A: The CTRIO/CTRIO2 itself does not have this capability, however, there is a way to accomplish this. If you are using the CTRIO/CTRIO2 in a DL-PLC then the CTRIO/CTRIO2 System Commands are utilized along with the retentive V-memory of the host PLC. If you are using the CTRIO/CTRIO2 in a Do-more PLC then this can be accomplished by using some Do-more system features and the CTREGWR instruction. 

If you are using the CTRIO/CTRIO2 in a DL-PLC:

• You will use the CTRRGWR "CTRIO Register Write" IBox to write to individual registers of the CTRIO/CTRIO2 from the PLC program; including writing to the current count. Thus, you can add code to the PLC program that will store the current count into retentive PLC V-memory every scan during normal operation. Then if power is lost, the current count will be retained in the PLC's retentive V-memory. Then, when power is restored, on the first PLC scan, this V-memory location can be written back directly to the current count of the CTRIO/CTRIO2 using the CTRRGWR IBox. Thus a "simulated" retentive action is accomplished.
  

• You will use the CTREGWR "CTRIO Write Register" instruction to write to individual registers of the CTRIO/CTRIO2 from the Do-more program; including writing to the current count. Thus, you can add code to the Do-more program that will store the current count into retentive Do-more D-memory every scan during normal operation. Then if power is lost, the current count will be retained in the Do-more's retentive D-memory. Then, when power is restored, before the first scan, this D-memory location can be written back directly to the current count of the CTRIO/CTRIO2. Thus a "simulated" retentive action is accomplished.
  
  To do this, for example, if the current count for Channel 1 Function 1 counter needs to be retentive, then in the $TopOfScan System Task code block put something like this:
  
  
  
  This will keep D0 updated with the current count value ($CTRIO_001_C1F1.iReg1) since it will be executed at the top of every scan of the PLC.
  
  The following code should be programmed into the $FirstScan System Task code block so that upon a power loss and subsequent power restoration, the current count that was constantly stored in D0 (and also retained) can be written back to the $CTRIO_001_C1F1.iReg1 register (0 - C1Fn1 Accumulator):
  
  
  
  Notice that a REPEAT/UNTIL loop is used. This is because the CTREGWR instruction is fully asynchronous (as denoted by the red triangle in the upper left corner of the instruction) and we don't want the rest of the scan of the PLC to start until this is completed. When it is successfully completed C100 will turn ON and the task will end and resume normal PLC scans.
  

CTRIO FAQ0022
17-Nov-2015
Q: Trying to control a stepper motor drive, but sometimes it moves in the wrong direction (e.g. staring up; homing).
A: Make sure that your stepper motor and stepper motor drive don't have a minimum frequency. If they do, then make sure, of course, that the CTRIO/CTRIO2 output frequencies are configured to put out at least that minimum frequency requirement or else you can get erratic performance (i.e. reversing direction) from your motor.

Q: What is the resolution of the Edge Timer?
A: The maximum resolution is one microsecond (1µs).

CTRIO FAQ0024
17-Nov-2015
Q: The CTRIO/CTRIO2 stays in the booter (OK and ERR LEDs are blinking) after attempting to upgrade its firmware; or gets "OS loader failure" error.
A: This is normally a bandwidth problem (i.e. the firmware telegrams aren't getting there in an efficient fashion. Here are some things that will cause this if the firmware upgrade is attempted:

• While the PLC/WinPLC is in the RUN mode.
• While the EBC/EBC100 is talking to an ERM/ERM100.
• While you are online with DirectSoft or Do-more Designer and Status is turned on.
• Through an ECOM/ECOM100 that is being used by an EZ Ethernet adapter.
• Via the Ethernet port of a Do-more PLC while the port is used for other various things.
  

So, before attempting to upgrade, make sure that none of the above is true (e.g. PLC is in PGM mode; ERM (not EBC/EBC100) is unplugged from network to free up the EBC/EBC100; DirectSoft or Do-more Designer isn't connected at all; etc.). If your CTRIO/CTRIO2 is in the booter mode already (OK and ERR LEDs are blinking), just rerun the firmware upgrade with the above precautions.

Q: When attempting to use the Import function for Freeform Pulse Profile, get "Error on line 1: ..." no matter what I do.
A: This is a bug exclusive to CTRIO Workbench v2.1.11 (all earlier versions work). This can be fixed by upgrading to:

CTRIO Workbench v2.1.12 (or later)

To download the latest CTRIO Workbench:
(1)  Goto www.hosteng.com.
(2)  In left column, click Hardware --> CTRIO.
(3)  Scroll down to CTRIO Workbench v2.1.12 (or later) link.

CTRIO FAQ0026 (see also EBC FAQ0082; PBC FAQ0013; WinPLC FAQ0037)
17-Nov-2015
Q: Why are the I/O Map values not saved if using CTRIO Workbench to talk to a CTRIO in an EBC/EBC100, WinPLC, or PBC base?
A: If the CTRIO/CTRIO2 is in any of these bases, the values entered in the CTRIO Workbench I/O Map do not determine the CTRIO's I/O address mapping. Something other than the CTRIO/CTRIO2 itself is determining this mapping (see chart below). Thus the I/O Map, in these cases, is merely a documentation function.

If you enter values in this map, they will not be saved in the CTRIO/CTRIO2's .CWB file that you might create. Thus, to remember the values, you will have to use the Report button at the bottom and then either Print a hard copy, or Save it to a .TXT file.

NOTE: To use the table, note what is controlling the base where the CTRIO/CTRIO2 is plugged into. Then note what is controlling the base controller itself. In the last column is the device or software that either determines the I/O mapping, or at least shows it to you.

Q: It appears that the CTRIO/CTRIO2 sometimes misses the Z-pulse from my encoder.
A: If this appears to happen (usually at higher frequencies) then you should upgrade the CTRIO to at least v2.0 or use a CTRIO2. There was a small window of time in the older CTRIO (v1.0) where it was possible for this to occur. The CTRIO firmware v2.0.1 and greater fixes this.

CTRIO FAQ0029

Q: How many counters can the CTRIO/CTRIO2 support?
A: The H2-CTRIO/CTRIO2 and H4-CTRIO can have 2 quadrature or 4 regular counters configured. The H0-CTRIO/CTRIO2 can have 1 quadrature and 2 regular counters configured.

CTRIO FAQ0030
18-Nov-2015
Q: Using Process Commands, the Command Complete bit never gets set. Everything in Monitor I/O works, however.
A: Consider:

• You could have a bug in your PLC program causing this. Therefore, try putting an END at the top of your program and then manipulating the CTRIO bits and words manually in a Data View. If manual control works, you have a bug in your PLC program.
• There was a bug in the H2-CTRIO firmware in versions less than (<) v2.1.6 where if you were using 4-range I/O mapping in the CTRIO that the Command Complete bit would never come on. Therefore if you have versions earlier than v2.1.6, then upgrade or use the newer H2-CTRIO2 module.
  

CTRIO FAQ0031
18-Nov-2015
Q: I need to read both the speed/velocity of my encoder input as well as the position (raw count). Is this possible?
A: Both the Scaled Units and the Raw Value are output from the CTRIO/CTRIO2 to the DL-PLC in the I/O Mapping dialog:

• If you picked "Floating Point" as the scaling format then:
• Scaled Units is in .fReg1
• Raw Value is in .iReg2
• If you picked any other scaling format (e.g. "Integer (rounded)", "BCD x10 (1 implied decimal place)", etc.) then:
• Scaled Units is in .iReg1
• Raw Value is in .iReg2
  

CTRIO FAQ0032
18-Nov-2015
Q: I need to control a CTRIO/CTRIO2 output based on both a speed/velocity input reading from my encoder as well as the position (raw count). Is this possible?
A: Even though Scaled Units and Raw Value are output from the CTRIO/CTRIO2 to the DL-PLC in the I/O Mapping and the CTRIO/CTRIO2 structure members in the Do-more PLC, you cannot configure a single CTRIO/CTRIO2 output to respond based on both the speed/velocity (Scaled Units) value and the position (Raw Value). You could, however, hook the encoder to 2 channels of the CTRIO/CTRIO2 and use 2 outputs; 1 to respond to the speed/velocity (Scaled Units) value and the other to respond to the position (Raw Value).

Q: How many quadrature encoders can I connect to a CTRIO/CTRIO2?
A: The H2-CTRIO/CTRIO2 and H4-CTRIO can support 2 quadrature encoders each. The H0-CTRIO/CTRIO2 can support only 1.

CTRIO FAQ0036
18-Nov-2015
Q: Using Temposonic quadrature absolute encoder, and occasionally the count in the CTRIO/CTRIO2 module jumps by 65,536 counts.
A: The Temposonic quadrature encoders actually artificially generate pulse trains based on the absolute position of their magnets. The faster versions are of high enough resolution that when they are at rest the electronic pulse generator inside is actually jittering. This causes direction changes for the CTRIO/CTRIO2 that are much too fast for it to handle (i.e. out of spec for the speed of the inputs); in fact, the direction changes are taking place faster than a real encoder with real mechanical motion could possibly generate. Thus it is not recommended that these style of encoders be used with the CTRIO/CTRIO2 unless you make sure that the resolution is large enough (i.e. not as sensitive) so as not to artificially generate these direction changes too quickly.

CTRIO FAQ0037
18-Nov-2015
Q: How is the Rate calculation performed by the CTRIO/CTRIO2.
A: Here are some real-life applications to help you understand how these settings work:

EXAMPLE #1 (RPM Value)

Let's say we want the CTRIO/CTRIO2 to give us the speed of a motor in RPMs (Revolutions Per Minute) instead of just counts. Attached to this motor we have an encoder that yields 800 PPR (Pulses Per Revolution). This encoder is connected to the CTRIO/CTRIO2's Inputs and the CTRIO/CTRIO2 Input has been configured as a Counter.

Thus the givens for this example are:
     - Rate value needs to be in RPMs.
     - Encoder is 800 PPR.

We now pull up the Scaling Wizard by pressing the Ruler () button. This gives the following dialog:

Pick Rate and press the <Next> button. This yields the following dialog:

Engineering Units: This is strictly 4 characters that can have any meaning we want. CTRIO/CTRIO2 doesn't care.
Output Format: This is how we want the scaling value reported to us. In this example, Integer x10 is picked just because we want a tenth of an RPM accuracy in the value reported. This means, for example, if we get a value back from the CTRIO/CTRIO2 such as 2124, this has 1 implied decimal place, which means the value is actually 212.4. We now press the <Next> button and get the following dialog:

Since we want our value to be in RPMs (Revolutions Per Minute), then we must set the Unit Time Base as minutes. Now, remember the encoder we are using yields 800 pulses in 1 revolution. Thus if it made 1 revolution in 1 minute, that would yield 800 pulses in 1 minute's time. So if the CTRIO/CTRIO2 Inputs see 800 pulses in the timespan of 1 minute, this would be 1 RPM. Thus, we must make the Counts / unit equal to 800 (800 pulses per minute = 1 RPM). Basically, we are done with the scaling and there is nothing else to configure. The Calc Options do not affect the scaling calculation being performed but are explained in CTRIO FAQ0070 and CTRIO FAQ0081.

Notice in this dialog, however, there is a tool called the Rate Scaling Calculator that can be used to verify our settings. Let's use it and see if it gives what we think it should:

Counts in sample: This is a number of counts we are going to consider. To make it easy, let's just say the CTRIO/CTRIO2 receives 800 pulses from the encoder, and thus counts to 800. So we enter 800.
Sample Time: This is the timespan in which the 800 pulses were received. Since we already know if the CTRIO/CTRIO2 gets 800 pulses in the timespan of 1 minute would equal 1 RPM, then we want to make the Sample Time equal to 1 minute. But the Sample Time is in ms (milliseconds). Thus, to enter 1 minute; this would be 60 seconds, or 60,000 milliseconds. So we enter 60000.
Scaled Value: Here is the answer. It will display 10 RPM. This is not 10 RPM, but rather 1.0 RPM because, in the Output Settings above we picked an implied decimal place. This proves that if the CTRIO/CTRIO2 gets 800 pulses in the timespan of 60,000 ms, that this would equal 1 RPM.

RATE SCALE FORMULA FOR RPM EXAMPLE

The formula the CTRIO/CTRIO2 uses to calculate the Rate Scaling is:

Or simplified as:

Where:

R = Result (This value is the Rate Scaling value output by the CTRIO/CTRIO2 to the PLC)
M = Multiplier (This value depends on the Output Format selected in the Scaling Wizard - Output Settings dialog).
U = Units in seconds (This value depends on the Unit Time Base selected in the Scaling Wizard - Rate Settings dialog).
C = Counts per unit (This value is the Counts / unit entered in the Scaling Wizard - Rate Settings dialog).
S = Scale offset (This value is the Scale Offset entered in the Scaling Wizard - Rate Settings dialog).
P = Pulse interval in seconds (This value is the Input to the CTRIO/CTRIO2 that is being scaled. It is the time in seconds divided by the number of counts received):

Using this formula with the RPM example above:

• M = 10 because Output Format = Integer x 10 (1 implied decimal place).
• U = 60 because Unit Time Base = minutes (1 minute = 60 seconds).
• C = 800 because Counts / unit = 800.
• S = 0 because Scale Offset = 0 (this is the case most of the time).

Since we are going to scale a particular count as received in a particular amount of time, let's use something we already know. We know in our example that if the CTRIO/CTRIO2 sees 800 pulses in 1 minute, that would be 1 RPM. Thus:

• P = 0.075 because:

Plugging the values in:

This is the same answer we received when we plugged the values into the Rate Scaling Calculator.
 

EXAMPLE #2 (FPS Value)

RPM scaling is the easiest example. Let's try something more complicated. Let's say we have a conveyor belt running and we want the value obtained from the CTRIO/CTRIO2 to be FPS (Feet Per Second). A proximity switch is connected to the CTRIO/CTRIO2 Input that detects the teeth on a gear. The gear has 30 teeth on it, and is coupled directly to a cylinder being driven by a motor to move the conveyor belt. The diameter of the cylinder is 10 inches.

Thus the givens for this example are:
     - Rate value needs to be in FPSs.
     - Proximity switch & Gear provide 30 PPR.
     - Cylinder driving the belt is 10 inches in diameter.

The CTRIO/CTRIO2 can only see the pulses generated from the proximity switch. Since we want the value the CTRIO/CTRIO2 gives us to be in FPS (Feet Per Second), we're going to have to figure out how much the cylinder must turn (and thus the gear with teeth detected by the proximity switch) to make the belt move 1 foot (12 inches). To figure this out, we must know the cylinder's circumference. If the cylinder's diameter is 10 inches, then:

This means when the cylinder turns 1 full turn, it has moved the belt 31.4159 inches. This 1 turn of the cylinder would also turn the gear 1 full turn, and thus generate 30 pulses on the proximity switch. Thus 30 pulses = 31.4159 inches of belt movement. But we are interested in feet, not inches. Since there are 12 inches in 1 foot:

This means when the cylinder turns 1 full turn, it has moved the belt 2.618 feet. Again, this 1 turn of the cylinder would also turn the gear 1 full turn, and thus generate 30 pulses on the proximity switch. Thus 30 pulses = 2.618 feet of belt movement. Now in order to configure the CTRIO/CTRIO2 to give us the right value, we need to know how many pulses the CTRIO/CTRIO2 Input will see if the belt only travels 1 foot because we are interested in FPS (Feet Per Second). Thus:

Of course, the CTRIO/CTRIO2 cannot see a fraction of a pulse, but the calculation for the Rate can certainly use a fraction. Thus we now know that when the cylinder has turned 1 foot, and thus turned the gear, the proximity switch will have generated at least 11 pulses. Thus, if the CTRIO/CTRIO2 sees 11 pulses, it knows the belt has traveled at nearly 1 foot. Realizing this, we can set the values.

We now pull up the Scaling Wizard by pressing the Ruler () button. This gives the following dialog:

Pick Rate and press the <Next> button. This yields the following dialog:

Engineering Units: This is strictly 4 characters that can have any meaning we want. CTRIO/CTRIO2 doesn't care.
Output Format: This is how we want the scaling value reported to us. In this example, Integer x100 is picked just because we want a hundredth of a FPS accuracy in the value reported. This means, for example, if we get a value back from the CTRIO/CTRIO2 such as 2124, this has 2 implied decimal places, which means the value is actually 21.24. We now press the <Next> button and get the following dialog:

Since we want our value to be in FPS (Feet Per Second), then we must set the Unit Time Base as seconds. Now, remember the gear/proximity switch we are using yields 30 pulses in 1 revolution, but only yields 11.4591 pulses when the belt has traveled 1 foot. So if the CTRIO/CTRIO2 Inputs see 11 pulses in the timespan of 1 second, this would be almost (but not quite) 1 FPS. Thus, we must make the Counts / unit equal to 11.4591 (11.4591 pulses per second = 1 FPS). Basically, we are done with the scaling configuration. The Calc Options do not affect the scaling calculation being performed but are explained in CTRIO FAQ0070 and CTRIO FAQ0081.

Notice in this dialog, however, there is a tool called the Rate Scaling Calculator that can be used to verify our settings. Let's use it and see if it gives what we think it should:

Counts in sample: This is a number we are going to consider. To make it easy, let's just say the CTRIO/CTRIO2 receives 11 pulses from the proximity swtich, and thus counts to 11. So we enter 11.
Sample Time: This is the timespan in which the 11 pulses were received. Since we already know if the CTRIO gets 11 pulses in the timespan of 1 second this would be almost 1 FPS, then we want to make the Sample Time equal to 1 second. But notice the Sample Time is in ms (milliseconds). Thus, to enter 1 second; that would be 1000 milliseconds. So we enter 1000.
Scaled Value: Here is the answer. It will display 96 FPS. This is not 96 FPS, but rather 0.96 FPS (almost 1 FPS) because, in the Output Settings above we picked 2 implied decimal places. This proves that if the CTRIO/CTRIO2 gets 11 pulses in the timespan of 1000 ms, that this would equal nearly 1 FPS as we expect. Remember the exact number of pulses for traveling 1 foot is technically 11.4591, but the CTRIO/CTRIO2 can't see fractional pulses, of course. But by increasing the Counts in sample to 12, you can see that the answer would now indicate slightly over 1 FPS, e.g. 1.05 FPS as we expect.

RATE SCALE FORMULA FOR FPS EXAMPLE

Using this formula with the FPS example above:

• M = 100 because Output Format = Integer x 100 (2 implied decimal places).
• U = 1 because Unit Time Base = seconds.
• C = 11.4591 because Counts / unit = 11.4591.
• S = 0 because Scale Offset = 0 (this is the case most of the time).

Since we are going to scale a particular count as received in a particular amount of time, let's use something we already know. We know in our example that if the CTRIO/CTRIO2 could see fractional pulses and it saw 11.4591 pulses in 1 second, that would be exactly 1 FPS. But since it can only see integer values for pulses, let's just use 11 pulses. As we saw above, this should give us a value less that 1 FPS. (The Rate Scaling Calculator gave us 96). Thus:

• P = 0.090909 because:

Plugging the values in:

Rounded up, this is the same answer we received when we plugged the values into the Rate Scaling Calculator.

CTRIO FAQ0040
08-Oct-2002
Q: When my CTRIO outputs are tied to Preset Tables, I cannot disable them. Why?
A: CTRIO outputs have two names:

• Raw Outputs - These outputs are turned ON and OFF with the Enable Output bit.
• Discrete Outputs - These outputs are tied to a Preset Table function and the Enable Output bit has no effect on them. Instead they are exclusively controlled by the Preset Table itself. This is by design for the purpose that once you configure the Discrete Output to a Preset Table there will be no PLC Ladders necessary for it to function. It is considered in an "Automatic" mode. If, however, you send a command to this channel, then it will go into a "Manual" mode and from that point on, it will have to be controlled by Ladders using the Enable Output bit.

CTRIO FAQ0044
23-Nov-2015
Q: Using a Preset Table I cannot get RESET COUNT at 1250 and RESET COUNT at -1250 to work.
A: This problem actually stems from a misunderstanding as to how the CTRIO/CTRIO2's Preset Tables function. Your table:

RESET COUNT at 1250
RESET COUNT at -1250

When the CTRIO/CTRIO2 sees a RESET COUNT instruction it zero's the count as expected, but it also resets the pointer back to the beginning of the table; which means that once the count is reset after reaching the value of 1250, it is goes back and starts looking for 1250 to happen again.

The function you are trying to get to work is more properly called a programmable limit switch (PLS). PLS functionality has been added to the CTRIO2. So to do this, instead of using Preset Tables, configure a PLS in the CTRIO2.

CTRIO FAQ0047
23-Nov-2015
Q: What do the values in the Workspace register mean in the various CTRIO IBoxes?
A: The Workspace register is used internally by the CTRIO IBoxes. Consequently, one should never write to this register. However, knowing the meaning of the various possible values can aid in troubleshooting the IBox if something goes wrong.

Generally the Workspace bits are defined as follows:
- Bit0 (i.e. Workspace = 1): Waiting for leading edge trigger of the IBox (power flow is OFF).
- Bit1 (i.e. Workspace = 2): Waiting for token (after leading edge is seen).
- Bit2 (i.e. Workspace = 4): Waiting for CTRIO/CTRIO2's Command Complete bit to go OFF
- Bit3 (i.e. Workspace = 8): Waiting for CTRIO/CTRIO2's Command Complete to come ON

Here are possible interpretations of these values:
- Workspace = 1: This means the IBox has seen that the input leg to the IBox is OFF and is now waiting for the input leg to come ON (thus providing the leading edge to get things going).
- Workspace = 2: This means the IBox has seen the leading edge trigger and is ready to execute, however, it doesn't have the internal token yet. In other words, there is some other CTRIO IBox that is currently executing for the same CTRIO/CTRIO2 module, it it has to wait for that one to finish and release the token.
- Workspace = 4: This means the IBox has seen the leading edge trigger and now has the token. It is now only waiting for the possibility that the CTRIO/CTRIO2's Command Complete bit has not yet turned OFF from a previous operation. This is just a quick check to make sure the CTRIO/CTRIO2 module is ready for a new Command.
- Workspace = 8: This means the IBox has seen the leading edge trigger, has the token, the Command Complete bit is OFF, and has executed his code giving the CTRIO/CTRIO2 a new Command to do and is now waiting for the CTRIO/CTRIO2 module to tell him he has completed the task.

Thus if you watch the Workspace register you will see it cycle through values 0, 1, 2, 4, 8 and back to 0 pretty fast.

If the IBox, for example, seems to not work and you look at the Workspace register and it is frozen at a value of 8, this usually means you have executed that particular IBox, say, in a Stage, and have terminated that Stage before the IBox gave you a Success or Error bit.

CTRIO FAQ0048
15-Feb-2008
Q: How do I change direction on the Pulse Outputs (i.e. direction of the motor)?
A: Direction is changed depending on the Pulse Profile you have loaded to control the Pulse Output.

NOTES:
   (1) - The example mapping is based on PLC - Mapped Addresses (4 ranges) with:
             Starting V address for word inputs:   V2000-V2017
             Starting V address for bit inputs:  V40600.0-V40605.15 (C0-C137)
             Starting V address for word outputs:  V2020
             Starting V address for bit outputs: V40606.0-V40613.15 (C140-C277)
   (2) - The CTRIO determines the direction by taking the difference between Parameter3 minus Current Position. If the result is positive, the Pulse Outputs will go one way; if negative, the other.
   (3) - Parameter3 is a signed decimal double-word. If it is negative, Pulse Outputs will go in one direction; if positive, the other.
   (4) - No tables are associated with these direct commands.

For NOTE (3) above, to load a negative value (32-bit 2's compliment; decimal) into Parameter3 (e.g. V2020-V2021) starting with a BCD number in V3000-V3001 you would do the following logic; if, however, the value in V3000-3001 is already in binary format then you would, of course, leave out the BIN box:

CTRIO FAQ0049
01-Nov-2002
Q: Can the H2-CTRIO interrupt the PLC when it reaches a certain count like the CTRINT module?
A: No. The H2-CTRIO does not have the ability to interrupt the CPU like the CTRINT. The reason is the DL205 backplane does not have an interrupt line for each slot. The slot adjacent to the CPU (Slot 0) has 4 of its address lines converted to interrupt lines that are only useable by the CTRINT.

CTRIO FAQ0050
02-Dec-2002
Q: Is the CTRIO configuration stored in battery-backed-up RAM?
A: No. The configuration for the CTRIO is stored in NVRAM (Non-volatile RAM) and therefore will not be lost on power failure or battery failure.

CTRIO FAQ0051 (see also DirectSOFT FAQ0163; ERM FAQ0032)
10-Dec-2002
Q: Will DirectSOFT work on Win95 32-bit OS?
A: We have seen this work on a few and not work on others. If it doesn't work we do not know of anything that can be done to make it work. However CTRIO Workbench and ERM Workbench will not even install if the InstallShield engine (used to install DirectSOFT) recognizes that the PC is Win95.

CTRIO FAQ0052
19-Dec-2002
Q: Is there a minimum load required for the CTRIO outputs?
A: No. The CTRIO output is a FET (Field Effect Transistor) which is normally 50m Ω(ohms). Leakage for this device is typically at 150μ amps at temperature extremes. Thus if the load is so small as to require only 150μ amps, then it could inadvertently turn on.

CTRIO FAQ0053
10-Feb-2003
Q:  Installed CTRIO Workbench v2.0 but no options to launch it show up in DSLaunch.
A: By installing CTRIO Workbench v2.0, changes are made to the DS400.INI file. However because you are using an older version of DirectSOFT these menu items cannot be displayed in DSLaunch. In order for these launch items to show up on the DSLaunch menu, CTRIO Workbench v2.0 requires at least DirectSOFT v4.0 Build 18.

Q:  Are there any slot restrictions for the CTRIO if installed in an EBC?
A: The following restrictions apply:

• If using H2-EBC with a hardware revision less than 9A, you can install H2-CTRIO in all slots except Slot 0 (the one adjacent to the EBC itself).

CTRIO FAQ0056
13-Mar-2003
Q:  While testing Run-to-Position function using Monitor I/O; it seems it doesn't function properly when I enter certain values for the next position.
A: This was a bug in CTRIO Workbench v2.0. The problem was that in Monitor I/O the position value in the CTRIO was internally using an Integer instead of a Floating Point value. To fix, upgrade to CTRIO Workbench v2.1.

Q:  In the Automation Direct catalog (pg. 4-68) it is stated that the CTRIO under certain conditions can output a pulse of up to 50 KHz; but Monitor I/O will not allow me to input a frequency higher than 25 KHz.
A: This was an original intention of the CTRIO, but it did not end up that way. The catalog is incorrect as the CTRIO stands now. The upper limit of the Pulse Output is indeed 25 KHz like Monitor I/O limits you to.

CTRIO FAQ0061
06-Aug-2004
Q: What causes the Output Stalled error bit to come on?
A: This bit means the Pulse Output train was interrupted because the CTRIO was too busy doing other things. Some things to try:

• Eliminate or reduce the use of the Edge Timing function.
• Eliminate or reduce the use of Rate Scaling.
• Reduce the frequency of the Pulse Output(s).
• Eliminate or reduce the use of other Pulse Outputting.
• Add a second CTRIO and divide these tasks among them.

02-Feb-2005
Q: Using an EBC100 and Modbus TCP protocol, how can I figure out where the CTRIO parameters are mapped into the Modbus addresses?
A: The easiest way to do this is to use NetEdit3 and CTRIO Workbench in combination. Follow these steps:

1. Using NetEdit3 (at least v3.4) to view the network that the EBC100 is connected to.
2. Right-click on the EBC100 and pick "Show Base Contents..."
3. Scroll down until you see your CTRIO I/O listed. It will look something like this:
   
   Base 0 : Slot 8 - Module Type 38 - T1H-CTRIO
                  96 - Bit inputs                     (Modbus 584/984 - Inputs 10025-10120)
                  96 - Bit outputs                   (Modbus 584/984 - Coils 25-120)
                  12 - Word outputs              (Modbus 584/984 - Holding registers 40017-40028)
                   8 - Double word inputs       (Modbus 584/984 - Input registers 30049-30064)
                   4 - Double word outputs     (Modbus 584/984 - Holding registers 40029-40036)

Here you can see that NetEdit3 has provided the Modbus addressing for you. Next you need only to see how these work in the CTRIO.

1. Using CTRIO Workbench (at least v2.1.9) connect to your CTRIO via the EBC100.
2. Press the <I/O Map...> button. (This is assuming that you have already configured your CTRIO the way you want).
3. Select "EBC - Mapped to MODBUS/TCP."
4. For "Starting input reg for word inputs:" enter the "Input register" number that you saw in NetEdit3 (e.g. 30049 in above example).
5. For "Starting input for bit inputs:" enter the "Inputs" number that you saw in NetEdit3 (e.g. 10025 in above example).
6. For "Starting holding reg for word outputs:" enter the smallest "Holding registers" address that you saw in NetEdit3 (e.g. 40017; not 40029 in above example).
7. For "Starting coil for bit outputs:" enter the "Coils" number that you saw in NetEdit3 (e.g. 25 in above example).

After manually entering these numbers from NetEdit3 into CTRIO Workbench's I/O mapping screen you can now see all the parameters and their appropriate Modbus TCP addressing.

CTRIO FAQ0063
15-Feb-2005
Q: Can I change the default folder for storing the CTRIO Workbench configuration files (.CWB)?
A: Yes. CTRIO Workbench uses the default projects folder as defined in the DS400.INI (or DS300.INI) file. When CTRIO Workbench starts up it looks for the DS300.INI file first and if it finds it, it will use the default projects folder as defined there. If it does not find the DS300.INI file, it will look for the DS400.INI file and use the default projects folder as defined there. If it cannot find the DS400.INI file then it will fault with: "Critical Error - ERROR 1004 - Invalid INI File" and will close when you press the <OK> button.

To change the default folder:

1. Close CTRIO Workbench (if you have it open).
2. From Windows desktop, Start --> Run...
3. Type in "ds400.ini" or "ds300.ini" whichever one you have.
   
   
    
4. Press <OK> button. This should open up a text editor (usually Notepad) showing the contents of this file.
5. Find the heading [PATHS]. Under this heading you will see a "PATH" line, looks something like:
   PATH=C:\DirectSOFT4\Projects\
6. Edit this path to point to one of your own choosing.
7. Save the file and exit.
8. Restart CTRIO Workbench.

Now when you use the <Write File> button the default folder will be the one you entered.

CTRIO FAQ0064
16-Feb-2005
Q: Using the "BCD (rounded)" selection for Position Scaling; the Position Scaling Calculator depicts a different behavior than what the CTRIO actually does.
A: Yes, this is a bug in the Position Scaling Calculator in versions of CTRIO Workbench of v2.1.9 or less. The incorrect behavior is in the Position Scaling Calculator itself. The CTRIO is actually functioning correctly in that it rounds the scaled value up like you would think (and like the function's name says). However, the Position Scaling Calculator does not round up; instead it is truncating the fraction.

Q: Can the duty cycle of the pulse output be changed if using Dynamic Velocity or Dynamic Positioning?
A: No. The duty cycle of the pulse output can, however, be changed using the System Commands "0x20 - Velocity Mode" and "0x22 - Run-to-Position Mode."

CTRIO FAQ0068
21-Sep-2005
Q: Can the accel/decel rates of the Dynamic Velocity Pulse Profile be increased to greater than 50,000? (i.e. instantaneous)
A: No. The highest rate is 50,000. If instant change from one frequency to another is desired you will have to use the Free Form Pulse Profile. This Pulse Profile has no accel/decel parameters and so you can output a number of pulses at one frequency and then go instantly to a different number of pulses at a different frequency. Of course the downside is that you no longer have the "dynamic" feature of Dynamic Velocity Pulse Profile.

14-Nov-2005
Q: When using Data Smoothing, what do each of the notches mean from "min" to "max"?
A: From "min" to "max" each notch represents an increasing number of samples that are averaged together to get a smoothing affect. The exact number of samples that are averaged respectively from "min" to "max" positions are:

For Rate Data Smoothing (10 slider positions): 1, 2, 3, 5, 7, 10, 13, 17, 21, 25

For Interval Data Smoothing (12 slider positions): 1, 2, 3, 5, 7, 10, 13, 17, 21, 25, 30, 36

Q: When using Interval Rate Scaling, if Data Smoothing is adjusted to anything other than Minimum, zero (0) is given in the Scaled Value answer.
A: This is a bug in CTRIOs with firmware that was accidentally introduced in v2.0.1 and up. Firmware v1.x actually worked! However, we have fixed this problem in the latest CTRIO firmware (v2.1.15).

CTRIO FAQ0072 (see also EBC FAQ0072; ERM FAQ0047; SDK FAQ0015)
09-Jan-2006
Q: In my H2-ERM/H2-EBC (or H2-EBC100) configuration, the H2-CTRIO word output (WO) and double-word output (DWO) mapping is different than where CTRIO Workbench indicates they should be.
A: This is caused by an I/O mapping problem in the H2-EBC and H2-EBC100 that is fixed in EBC firmware v2.1.441 and later. It has to do with the H2-CTRIO "I/O type." The H2-CTRIO is now reported as a Type 7 module instead of a Type 5 module. This new reclassification of the H2-CTRIO as a Type 7 allows the EBC to manage the order in which things get mapped.

The symptom shows up as a mapping discrepancy in the order in which the CTRIO puts the DWOs and the WOs VS where the ERM Workbench maps them in PLC memory.

For example, for comparison see the chart below:

NOTE: If you update the EBC firmware to fix this problem, make sure that you are at least using CTRIO Workbench v2.1.10 to configure the H2-CTRIO.

CTRIO FAQ0073
03-Jan-2006
Q: Can the Reset Value as configured on the Config I/O page of CTRIO Workbench be changed on the fly from ladders?
A: No, not that one. Basically there are two Reset Values:

1. Hardware Reset Value that is on the Config I/O page of CTIRO Workbench cannot be changed from ladders. This value is the one that will be written to the Current Count when a hardware reset is seen (i.e. Input C) as configured.
2. Software Reset Value that is the result of using the Reset Bit. This particular Reset Value is a software-only Reset Value and is the value that is written to the Current Count when the Reset Bit is set by ladders. This value can be changed on the fly from ladders using System Function 0x05 "Write reset value."

CTRIO FAQ0074
31-Jan-2006
Q: In the S-Curve (& Symmetrical S-Curve) Pulse Profiles, what do the Min Freq Change and Min Entry Time parameters do?
A: These parameter define the resolution of the S-Curve itself. First of all, the CTRIO is not designed to be a sophisticated motion control device. When you use CTRIO Workbench to configure an S-Curve Pulse Profile, Workbench calculates entries for a table that defines the curve. It is this table that is downloaded into the CTRIO itself. In other words, the CTRIO itself does not do complex math "on the fly" to come up with this curve; that would take too much valuable CTRIO scantime. Instead, the CTRIO is just blindly outputting values from this predefined table. With that understanding:

Min Freq Change: This is a percentage (between 1-10%) that changes the vertical frequency resolution of the output curve. In other word, it is the Y-axis of the graphical representation that you see in CTRIO Workbench. If you change this value and press the <Calculate Profile> button you will notice the vertical resolution of the graph changes. With 1% the CTRIO can use more frequencies and so it is smoother; at 10% the CTRIO will use less frequencies and so it become very course.

Min Entry Time: This is a time (between 1-255ms) that changes the horizontal time resolution of the output curve. In other words, it is the X-axis of the graphical representation that you see in CTRIO Workbench. If you change this value and press the <Calculate Profile> button you will notice the horizontal resolution of the graph changes. With 1ms the CTRIO can use smaller steps and so it is smoother; at 255ms the CTRIO will use less time increments and so it becomes very course.

Thus, with these 2 parameters you control the smoothness of the CTRIO output curve. If you make both parameters very small, the S-Curve will look very smooth, but you also create a bigger table and thus take up more configuration space in the CTRIO:

 If you make both parameters very large, the S-Curve will look very course, but you also create a smaller table and thus take up very little configuration space in the CTRIO.

CTRIO FAQ0075
08-Feb-2006
Q: Will the CTRIO support differential encoder outputs?
A: No. The CTRIO inputs are single-ended in that the M connection is common to all 4 inputs (A, B, C, D). Tying 2 differential encoder outputs together is not a good idea so we'd be limited to 1 input at the most (e.g. A and M). Also because of the sink/source capabilities of the CTRIO inputs, a positive or a negative signal above 9V threshold would be treated as an ON. So even using a single differential signal greater than 9V each side of ground (M), the CTRIO would count both states as ON and therefore count at twice the expected rate. If distance and electrical noise are the reason for using the differential encoder, twisted pair wiring is usually good enough because the CTRIO inputs stay OFF at up to 2 mA and 2V.

CTRIO FAQ0076
13-Feb-2006
Q: Using quadrature counter at 1X, how does the CTRIO increment counts after a reset? Does it synchronize to the rising edge of Input A?
A: After a reset, the CTRIO count defaults to the DOWN direction. Thus if the CTRIO is to count pulses in the UP direction after the reset, then, depending on the configuration, it may need as much as 4 edges to reestablish the UP direction. However, if the CTRIO is to count pulses in the DOWN direction, it will continue without having to reestablish a direction.

For the COUNTING-UP scenario, the rules are:

For 1X quadrature counting: After the reset CTRIO is in the DOWN direction. It takes 4 edges to reestablish the UP direction. On the 4th edge CTRIO will increment the count and then from this point onward it will increment the count on the rising edge of Input A

For 2X quadrature counting: After the reset CTRIO is in the DOWN direction. It takes 2 edges to reestablish the UP direction. On the 2nd edge CTRIO will increment the count and then from here it will increment the count when Input A and Input B are in opposite states or after 2 more edges (which ever comes first). Then from this point onward it will increment the count when Input A and Input B are in opposite states.

For 4X quadrature counting: After the reset CTRIO is in the DOWN direction. It only takes 1 edge to reestablish the UP direction. So CTRIO counts all edges all the time.

These COUNTING-UP rules are displayed in the following tables:

Count gets Reset while Input A = 0 and Input B = 0:

Input A	Input B	Count (1X)	Count (2X)	Count (4X)
1	0	0	0	1
1	1	0	1	2

0	0	1	2	5
1	0	2	3	6
1	1	2	3	7
0	1	2	4	8
0	0	2	4	9

For the COUNTING-DOWN scenario, the rules are:

For 1X quadrature counting: After the reset CTRIO is in the DOWN direction therefore it will continue to count down on the falling edge of Input A.

For 2X quadrature counting: After the reset CTRIO is in the DOWN direction therefore it will continue to count down when Input A and Input B are in the same state.

For 4X quadrature counting: After the reset CTRIO is in the DOWN direction therefore it will continue to count down on all edges all the time.

These COUNTING-DOWN rules are displayed in the following tables:

Count gets Reset while Input A = 0 and Input B = 0:

Input A	Input B	Count (1X)	Count (2X)	Count (4X)
0	1	0	0	-1

CTRIO FAQ0077
13-Feb-2006
Q: Does the Scan Time of the CTRIO (as indicated in CTRIO Workbench) affect the response time of the Pulse Output to Presets in the Preset Tables?
A: Yes. There are 3 levels of processing in the CTRIO; (1) hardware dependant; (2) interrupt dependant and (3) scan time dependant. In the case of Presets in the Preset Tables that change the state of the Pulse Outputs, this is handled in the (3) scan time dependant processing. Thus, the maximum time from reaching a Preset count to a change in the Pulse Output as configured in a Preset Table is the Scan Time of the CTRIO. For this to be any different the CTRIO would have to have much faster hardware, which would be more expensive. Thus for an example:

Count coming into the CTRIO rising-edge counter at a rate of 25 KHz and we have a Preset Table with an entry of SET at 12 and a CTRIO Scan Time of 600 µs.
     -  At 25 KHz, that is a rising edge every 1 / 25000 = 0.00004 seconds (or 40 µs)
     -  The count of 12 will take 12 x 40 µs = 480 µs
     -  If this event occurred immediately after the CTRIO had already updated its Pulse Outputs, then it could be about 600 µs before the Pulse Output was updated. Thus an event that should've happened in 480 µs ended up taking 480 + 600 = 1.08 ms. This would tend to give you a similar response for all Preset Values that are faster than the Scan Time of the CTRIO.

CTRIO FAQ0078
13-Feb-2006
Q: Does the CTRIO have a "follower" mode (i.e. produce a Pulse Output at the same velocity as an encoder input)?
A: No, there is no intrinsic follower mode for the CTRIO. The only way to make the CTRIO Pulse Output follow the Rate of a CTRIO counter input is:

1. Configure a CTRIO output as a Pulse Output.
2. Configure a Dynamic Velocity Pulse Profile.
3. Configure a CTRIO Input Channel as a counter and use the Scaling Wizard to make it yield a Rate.
4. In the PLC program, load the Dynamic Velocity Pulse Profile Table.
5. In the PLC program load the V-memory for the CTRIO "Scaled Units" and output that to the V-memory for the CTRIO "Parameter 3" (Velocity).

This should work well in most applications simply because the delay between a change of Rate on the CTRIO Input to the change of Velocity on the CTRIO Pulse Output will, at the most, be about 2 PLC scantimes (i.e. in the millisecond range).

CTRIO FAQ0079
27-Feb-2007
Q: What is the difference between Edge-Triggering and Level-Triggering?
A: Here are the differences:

EDGE TRIGGERING: The inputs are sampled by the CTRIO hardware every 16 MHz clock cycle. If the edge exceeds 2V and 2mA, then an edge is reported to the CTRIO firmware as a trigger interrupt. Thus the CTRIO hardware is totally in control of the triggering.

LEVEL TRIGGERING: The inputs are sampled by the CTRIO hardware every 16 MHz clock cycle. If the edge exceeds 2V and 2mA, then a change of state is reported to the CTRIO firmware. As the CTRIO firmware scans and notices there has been a change of state from 0 to 1 of one of its inputs, then it "knows" there was a trigger. Thus the triggering is based not on just an edge detection by the hardware, but also is somewhat delayed by the scantime of the CTRIO.

Therefore, if edge triggering is falsely being triggered by an excessively noisy signal, oftentimes changing to level triggering will filter these false triggers out. However, nothing is a good substitute for a clean signal on the inputs in the first place.

CTRIO FAQ0080
09-Mar-2007
Q: Can the configuration of the CTRIO be printed out using CTRIO Workbench?
A: No, but the configuration can be saved in a .CWB file. The only thing that can be printed out is the I/O map.

CTRIO FAQ0081
15-Feb-2010
Q: What does the Calc Interval  have to do with Rate and Interval Scaling?
A: Calc Interval is just so you can tell the CTRIO how many times you want the CTRIO to calculate the Rate or Interval scaling. In other words, if you need a more accurate measurement and are monitoring the value closely (i.e. high-speed), then calculating this value more frequently would be needed. But is would be useless to calculate it faster than the scantime of your PLC, since the PLC can only look at the value once per scan anyway. If, however, the value is not that high-speed and not needed by the process to be very accurate, then calculating this value less frequently would be better.

CTRIO FAQ0082 (see also PBC FAQ0016)
22-Nov-2010
Q: Cannot get CTRIO Workbench's Monitor I/O function to work with the PBC.
A:  Unfortunately, it is not possible to have this functionality for the CTRIO in the PBC. To comply with specification, CTRIO Workbench cannot suspend the PBC's writing/reading the CTRIO's I/O in order to perform the function, thus it is not supported.

CTRIO FAQ0083
07-Mar-2011
Q: How fast is the CTRIO-TTLANNEX board?
A: The transistors themselves are actually rated at 300 MHz, but due to other design restraints we do not recommend you go over 10 MHz. However, if you are using them with the current CTRIO module itself, the CTRIO input can only go to 100 KHz.

CTRIO FAQ0084
07-Apr-2011
Q: Edge detection on the Run to Limit function (CTRRTLM IB-1011) doesn't work properly.
A: The problem here is the documentation. The Run-to-Limit function in the CTRIO does NOT use an edge detection but rather a level detection. The CTRIO manual (pgs. 6-42 thru 6-43), the DirectSOFT Help file (help for CTRRTLM IB-1011 IBox) and our very own CTRIO Flow Charts.PDF document all had this wrong. Thus, since it is a level detection on the Limit Input, the "Both Edges" detection setting is invalid and the "Rising Edge" is actually a "High Level" and the "Falling Edge" is actually a "Low Level". The idea, for example, in the real world was if the machine was already at the limit switch (Limit Input) then it is not necessary to move the machine at all.

The following chart show the correct values for Parameter2:

00    Channel 1 Input C high level limit
10    Channel 1 Input C low level limit
01    Channel 1 Input D high level limit
11    Channel 1 Input D low level limit
02    Channel 2 Input C high level limit
12    Channel 2 Input C low level limit
03    Channel 2 Input D high level limit
13    Channel 2 Input D low level limit

The CTRIO manual will be corrected in the next release.
The DirectSOFT Help file will be corrected in the next release.
The CTRIO Flow Charts.PDF document has been corrected already.

CTRIO FAQ0085
24-Aug-2011
Q: Is it possible to connect the TTL-level differential encoder outputs of the SureServo to the CTRIO?
A: Yes. But it is necessary to use the CTRIO-TTLANNEX board to step up the voltage levels for the CTRIO inputs. Also since the SureServo encoder outputs on connector CN1 are differential (0A, /OA, OB, /OB, OZ, /OZ) and the CTRIO inputs are single-ended, the /OA, /OB and /OZ signals cannot be used. Instead only the OA, OB and OZ with reference to any GND terminal on CN1 are needed.

CTRIO FAQ0086 (see also Do-more FAQ0028)
14-Mar-2013
Q: Must CTRIO Workbench be used to configure CTRIO and CTRIO2s in Do-more?
A: No, CTRIO Workbench cannot be used with Do-more. Instead, the configuration of CTRIO/CTRIO2 modules is done in Do-more Designer software in the PLC --> System Configuration --> Module Configuration. The CTRIO/CTRIO2 configuration is no longer stored in the module itself, but rather the Do-more CPU (DM1/DM1E).

Also, in Do-more the CTRIO/CTRIO2 parameters are not mapped into V-memory as was the case in DL-PLCs. Instead the various CTRIO/CTRIO2 parameters are mapped to Do-more Structured memory as Structured members (e.g. CTRIO_000_C1F1.AtResetValue is CTRIO zero Channel 1 Function 1's "at reset" parameter bit). See table below for members that can exist. Not all members exist for every CTRIO/CTRIO2 configuration. See Do-more Designer Help file for specific details for any given CTRIO/CTRIO2 configuration and useage (i.e. ladder instructions):
