            Q: Does the WinPLC allow for an ERM?
          
          A: Yes. The WinCE-only version can have up to 6 ERMs (due to power
          budget limitations) and each ERM supporting as many as 16 EBCs.
          However
          if the WinPLC you are using is a Think&Do version you are
          limited to only 1 ERM and that ERM can only have 1 EBC.

          06-Feb-2003
          Q: CTRIO Workbench indicates that the CTRIO module is in
            "Startup" mode and all of the configuration parameters are grayed
            out.
          A: "Startup" mode indicates that CTRIO Workbench cannot
          successfully communicate with the CTRIO. The problem is not between
          CTRIO Workbench and the CPU, the problem is between the CPU and the
          CTRIO itself. Communication across the backplane is failing. Here are
          some known causes of this:
* - Revision meaning: "7F" means: "7" is bare board revision. "F" the revision of the assembly drawing that we are using to build the boards.
If you have older EBC, PBC or WinPLC hardware, you have two options to get them updated:
- RMA them back to Automation Direct (a part will be shipped immediately to you).
- Send them to Host Engineering (you will have to wait on the part to be modified and shipped back).

          07-Feb-2003
          
            Q: Can the MAC address be changed?
          
          A: The MAC address is burned into the ROM of the device and is set
          just
          before it leaves the factory. There is no logical way for any protocol
          to change this address. Host Engineering’s range for
          Ethernet MAC addresses is 00.E0.62.xx.xx.xx.
However, there was a bug with the old Ether32.EXE program that could change the MAC Address! If you use Ether32.EXE to update the booter using TCP/IP protocol (i.e. use the "/pi" option on the command line), then the MAC Address could be changed by accident!

          22-Apr-2003
          
            Q: How many EBCs can one ERM support?
          
          A: Normally 16. But if the CPU is a Think&Do WinPLC then this
          is limited to 1 (this limitation does not apply to the WinCE-only
          version of the WinPLC).
WinPLC FAQ0006
          17-Feb-2003
          
            Q: Does the WinPLC have an embedded web server?
          
          A: No. The problem is that WinPLC uses Windows CE v2.12 and this is a
          limitation of
          Windows CE. The WinPLC, though it has a flash drive on it, does not
          appear as a PC on a network that you can browse to. It may be that
          later versions of
          Windows CE may have this feature, but the current one we are using
          does
          not.

          (see also CTRIO FAQ0016)
          17-Feb-2003
          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:

            Q: If I want to send my WinPLC back to Host Engineering for repair;
            how
            do I do
            this?
          
          A: E-mail support@hosteng.com
          and give
          the details of why you want to do this. Our Product Manager will then
          respond
          with an authorization and a repair price.
WinPLC FAQ0009
          28-Feb-2003
          
            Q: What is the fastest that my Think&Do WinPLC will execute PID
            loops?
          
          A: The flowchart executing the PID block determines the loop update
          rate. The
          fastest time a PID block can be executed is once every 10 ms. This
          rate
          doesn't
          change with the speed of the WinPLC you are using.
WinPLC FAQ0010
          20-Mar-2003
          
            Q: Can the WinPLC handle 10 communication ports simultaneously? What
            kind of
            affect will this have on the normal process?
          
          A: WinPLC can handle a maximum of 10 communication ports
          simultaneously. Each
          port is handled by interrupt as it gets data. Each port has a 16-byte
          buffer. It
          can therefore handle this kind of simultaneous communications task
          extremely
          fast especially at lower bps (e.g. 9600). Of course, as the bps is
          increased
          then this takes more and more processing time to keep up with the data
          that is
          getting dumped into the buffers. Also, keep in mind that the WinPLC is
          more like
          a conventional PC rather than a PLC. Therefore it is very difficult to
          determine
          exactly what kind of an effect this will have on your normal process.
WinPLC FAQ0011
          04-Sep-2002
          
            Q: When upgrading the firmware in my WinPLC the process stops half
            way
            through and it gets stuck in boot mode.
          
          A: Make sure that the time stamp on the file wplc.exe is greater than
          11/01. If you still have trouble after getting a newer version it
          could
          be caused by a bad flashcard in the WinPLC. For repair see WinPLC
            FAQ0008.
WinPLC FAQ0012
          (see also SERIO FAQ0001; EBC FAQ0028)
          09-Sep-2002 
          
            Q: Are there slot restrictions for the SERIO module?
          
          A: There is no slot restriction for the H2-SERIO module.
WinPLC FAQ0013
          (see also EBC FAQ0030, CTRIO FAQ0014)
          11-Feb-2003
          Q: What is the expected hit on the scan time for adding an
            H2-CTRIO to WinPLC
            or EBC rack? When I connect with Entivity and add more than one
            H2-CTRIO 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 itself, the addition of a CTRIO will probably not be noticeable at all simply because the EBC has only one thing to do . . . update its I/O.
On a Think&Do or Entivity application there will be about 7ms/CTRIO hit due to the number of tags that are created to handle the extra I/O scanning of the CTRIO from the PC. Thus, in the Connectivity Center of this software, under "Attributes" you must increase the "Timeout Value for Retries(ms)" value accordingly.

          05-Feb-2008
          Q: After writing configuration to ERM and EBC get "Error 228 -
            Backplane error."
          A: Error 228 is defined as "Backplane read/write request
          queue full" and it means that for some reason the CPU is either
          rejecting requests from its ERM or not accepting them. Common causes:

          Q: Which H2-EBC, H2-PBC and H2-WPLC work in the newer DL205
            "-1" bases?
          A: The following states the hardware revision requirements
          for using these products in the newer DL205 "-1" bases (the ones that
          have the local expansion I/O connector on the right side):
Find the hardware revision number on a label on the right side of the PCB (printed circuit board) as shown:
WinPLC FAQ0016
          10-Oct-2002
          Q: Sometimes when I power up my WinPLC it loses its IP address.
          A: This is actually a bug in the WinCE v2.11 image and not
          really a WinPLC problem. Since Host Engineering cannot fix WinCE bugs,
          we extensively tested a WinPLC with WinCE v2.12 and found that it
          doesn't have this bug. Thus since the problem is in WinCE v2.11 then
          the solution is to get WinCE v2.12...
If you have an Entivity WinPLC you simply need to upgrade to the latest WinPLC runtime that's appropriate for your development package. You may have to obtain the image on CD from Entivity because it is rather large for Internet downloading.
If you have a WinPLC CE-only there may be a problem. Currently the WinCE v2.11 runtime image allows for Visual C/C++/Basic program development. But unfortunately the image for WinPLC CE-only that has WinCE v2.12 on it only allows for Visual C/C++ program development. Thus if you developed the program in Visual Basic you are stuck with a runtime that has this bug. But if you used Visual C/C++ then Host Engineering can update your runtime image to WinCE v2.12 which does not have this bug.
WinPLC FAQ0017
          22-Mar-2004
          Q: Is there a WinCE.NET compatible WinPLC?
          A: No. The problem is that the WinPLC is headless (i.e. no
          monitor; no keyboard; no mouse; etc.) and Microsoft has not produced a
          headless version of WinCE.NET yet.

WinPLC FAQ0019
          07-Nov-2002
          
            Q: Does the WinPLC WinCE version use 16-bit or 32-bit processing? 
          
          A: 32-bit processing, but not Intel. It uses a Hitachi SH3 Series 7708
          processor for embedded applications.
WinPLC FAQ0020
          07-Nov-2002
          Q: What version of WinCE do the various WinPLCs have on them?
          A: Refer to the following:
| Product | Description | WinCE Version | 
| H2-WPLC1-LV | 40 MHz WinPLC with Think&Do Live | v2.11 with Think&Do less than v5.5.1 | 
| v2.12 with Think&Do v5.5.1 or greater | ||
| H2-WPLC1-SD | 40 MHz WinPLC with Entivity Studio | v2.11 with Entivity Studio less than v7.1 |

WinPLC FAQ0021
          30-Oct-2002
          Q: Using Think&Do v5.2 with H2-WPLC1-LV and getting a
            timeout error about 90% of the time.
          A: Our original WPLC.EXE had a fixed timeout value during
          chip-erase cycle that was too short for some chips. These particular
          chips take way too long to update, so we've been replacing them on
          RMAs
          and we changed our production test set to catch them so they don't get
          out. So, the first thing to try is...

          (see also SDK FAQ0009)
          10-Dec-2002
          Q: Is there an SDK for the WinPLC?
          A: Yes; for WinPLC CE-only version that uses WinCE v2.11. You
          can download the 4MByte .ZIP file on our "S/W Developer Kits -->
          WinPLC" page (http://www.hosteng.com/WinPLC%20SDK/WinPLC%20SDK.htm).
WinPLC FAQ0023
          29-Jan-2003
          Q: Have a WinPLC CE-only, how do I address the I/O in my
            ERM/EBC rack?
          A: How to do this is not very straightforward. Basically the
          WinPLC
          CE-only program must put the data in a form that the ERM is expecting.
          Details are contained in the software modules themselves that you call
          to do this; however, it is probably better to send us an e-mail
          question
          (SDKSupport@hosteng.com).
WinPLC FAQ0024
          06-Mar-2003
          Q: Can the EZ Touch panel communicate with a WinPLC
            (Think&Do)?
          A: Yes. The drivers are in the Entivity (Think&Do)
          software as well as the instructions as to how to do this.

          (see also ERM FAQ0033)
          21-Apr-2003
          Q: What is the minimum hardware revision number of the WinPLC
            in order for it to work with an ERM in a -1 base? 
          A: There are no known problems with using an ERM with the
          WinPLC at all regardless of the type of base.
WinPLC FAQ0027
          18-Nov-2004
          Q: If using CEWatch.EXE to configure the WinPLC; will the
            "Reset IPX" function clear the WinPLC running program? 
          A: This function clears the WinPLC's RAM, but not its ROM. In
          other words, it makes the WinPLC reboot (like a PC would), and then it
          reloads the running program from its ROM back to its RAM to start
          again.

          22-Nov-2002
          Q: Is it possible to utilize the CTRIO System Functions
            everywhere it can be installed?
          A: In firmware v2.x System Functions were added to the CTRIO
          products (H0-, H2-, H4- and T1H-CTRIO). These System Functions would
          allow you to write (and read) various internal registers of the CTRIO.
          The following table shows what scenarios that these System Functions
          can be used and how to use them:
| System Function | CTRIO Configuration | |||||||
| Local DL PLC Base | Remote DL PLC Base | DL PLC with ERM/EBC | WinPLC (Think&Do) Local Base | WinPLC (Think&Do) with ERM/EBC | Think&Do (Entivity) to EBC | Ethernet SDK to EBC | ||
| Mapped System Functions (i.e. in V-memory) | Status of Inputs | YES | NO (4) | YES | YES | YES | YES | YES | 
| Mode & Status of Outputs | YES | NO (4) | YES | YES | YES | YES | YES | |
| CTRIO Shared RAM System Functions | 0x01 - Read all registers | YES (1) | NO (4) | NO (5) | YES (2) | YES (2) | YES (2) | YES (3) | 
| 0x02 - Write all registers | YES (1) | NO (4) | NO (5) | YES (2) | YES (2) | YES (2) | YES (3) | |
| 0x04 - Write one register | YES (1) | NO (4) | NO (5) | YES (2) | YES (2) | YES (2) | YES (3) | |
| 0x05 - Write reset value | YES (1) | NO (4) | NO (5) | YES (2) | YES (2) | YES (2) | YES (3) | |
(1) -
          Use RD/WT instruction in Ladders.
          (2) - Use Shared RAM Operations for CTRIO in a CALL
          block.
          (3) - Use Ethernet SDK routine HEIWriteSharedRAM /
          HEIReadSharedRAM.
          (4) - Not possible because CTRIO will not work in
          remote bases.
          (5) - Not possible because Ladders cannot tell the
          ERM to access the Shared RAM of CTRIO in EBC base.
WinPLC FAQ0030
          21-Oct-2005
          Q: What is the scantime of a WinPLC?
          A: If it is a Think&Do WinPLC, then the default is
          50ms, however Think&Do will allow you to modify that in
          increments of 1ms. If it is a WinCE-only WinPLC, then the scantime
          depends on how much you program it to do; but the resolution of the
          scantime is also 1ms.
WinPLC FAQ0031
          28-Oct-2005
          Q: Can the retentive memory size be increased in a WinPLC?
          A: No. The size is not software or firmware limited; it is
          actually a hardware limitation.

          Q: Does the WinPLC CE-only version support Visual Basic (VB6
            or VB.NET)?
          A: The current version of the WinPLC is shipped with WinCE
          v2.12 in it, and this version of WinCE does not have Visual Basic in
          it
          at all. The older version of the WinPLC was shipped with WinCE v2.11
          and it did, however, have Microsoft Embedded Visual Basic in it (but
          this is not VB.NET, nor VB6). But we switched to WinCE v2.12 because
          there was a bug in the WinCE v2.11 that would sometimes cause the
          WinPLC to lose its IP address on power up. Thus, as you can see, there
          is not a great solution using Visual Basic and the WinPLC. If you can
          live with the possibility of the bug mentioned, then you can download
          this WinPLC image from our website (www.hosteng.com --> Software
          Developer Kits --> WinPLC).  
WinPLC FAQ0035
          (see also SERIO FAQ0003)
          22-May-2006
          Q: What is the size of the communication buffer for the
            H2-SERIO and how do I send long strings of data with WinPLC CE-only
            version?
          A: The communication buffer for each port of the H2-SERIO is
          16 bytes long. However, means are provided in the WinPLC SDK functions
          to write long strings of data through this size buffer. You send the
          long string and then the buffer will communicate back how many bytes
          were sent. Based on this number you can reset your pointer in your
          string and send again. In this manner long strings of data can be
          sent.
          Of course, at higher baud rates the number of bytes that get sent each
          time will be much larger.

          (see also CTRIO FAQ0012; EBC FAQ0079)
          26-Mar-2010
          Q: When trying to connect to CTRIO 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 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.

          (see also CTRIO FAQ0026; EBC FAQ0082; PBC FAQ0013)
          01-Jun-2009
          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 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 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 .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 H*-CTRIO 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: What is the export classification of your products (e.g.
            ECCN)
          A: None of our products have an ECCN. Automation Direct sells
          our products and they export EAR99 NLR (No License Required).
          ECCN is Export Controlled Classification Number and
          none of our products are controlled.
WinPLC FAQ0039
          (see also SERIO FAQ0005)
          13-Dec-2010
          Q: How does the WinPLC SDK see the H2-SERIO?
          A: The WinPLC (and WinPLC SDK) will treat each of the 3 ports
          on the H2-SERIO exactly the same as it does the onboard serial port
          and
          it can support 3 H2-SERIO modules. The onboard serial port is COM1 so
          the subsequent COM ports on 3 more H2-SERIOs would be:
1st
        H2-SERIO: COM2, COM3, COM4
        2nd H2-SERIO: COM5, COM6, COM7
        3rd H2-SERIO: COM8, COM9, COM0
This gives you a total of 10 serial ports possible.

          05-Mar-2012
          Q: The H2-SERIO nor the H2-SERIO-4 communicates when
            installed with an H2-WPLC3?
          A: This is a PLD (firmware) issue with the H2-SERIO and
          H2-SERIO-4.
          In order to fix this issue the H2-SERIO or H2-SERIO-4 must be sent
          back
          to Host Engineering to be upgraded (free of charge). The version of
          hardware that works is:
          
          H2-SERIO Rev 5CA
          H2-SERIO-4 Rev 5CA
          
          Contact support@hosteng.com to have yours upgraded if you encounter
          this problem.

            FAQ0041 (see
also ERM
          FAQ0066, EBC FAQ0093)
      06-May-2014
          Q: Cannot get H2-ERM100
            to work with H2-WPLC3 (Entivity/Think&Do); gets red light and
            EBC100 watchdogs (times out).
          A: The H2-WPLC3 (hardware revision 3A) is not
          compatible with the H2-ERM100. This is due to a necessary memory chip
          change in the WinPLC due to part obsolescence. At one time
          the only solution was to use an H2-ERM instead of the
          H2-ERM100. But the problem now has no solution because there are no
          more H2-ERMs to be had. We can no longer produce them, and Automation
          Direct is out of stock. Thus the use of any H2-WPLC3 with remote I/O
          via ERM/EBC combination is no longer an option.
We, therefore suggest that consideration be given to using a Do-more PLC instead.
