Q: Can I use NetEdit to do firmware updates?
A: Older versions of NetEdit would not allow this, but with NetEdit3 this is possible!
Q: Can TCP/IP protocol be used to upgrade firmware as well as IPX?
A: With NetEdit3 it is possible to upgrade firmware using IPX or TCP/IP protocols.

Q: NetEdit sees ERM, EBC and EDRV, but ERM Workbench gets error "ERM not found" when trying to write the configuration to the ERM.
A: Downloading the latest version of ERM Workbench may remedy this problem; especially if you are using the ERM Workbench Wizard. You should download at least ERM Workbench v1.1 Build 26. Otherwise here are some things to try:

FAQ0025; EDRV FAQ0011; ERM FAQ0052; EZ Ethernet FAQ0007)
Q: Can retries and timeout values for NetEdit be adjusted to allow it to find Host Ethernet devices on much slower networks?
A: No, but we will probably include this ability in future releases of NetEdit (greater than v3.7). Currently NetEdit sends out a broadcast and waits 600 ms for devices to respond. If the devices take longer than this to respond they will be missing from his list. After the responses are gathered, NetEdit makes a list and then polls each device in the list one at a time to get detailed data, but waits only 250 ms for response from each device. If the device takes longer than this to respond some of its data may be missing. This is not a problem on a normal wired network, but can be a problem on a wireless network or across the Internet where responses can inadvertently be long and inconsistent. Also, since a broadcast is used, any device between NetEdit and the Host Ethernet modules that block broadcasts can prevent NetEdit from seeing anything.

Q: Why doesn't the ECOM use subnet mask or gateway address like the ECOM100?
A: Since the ECOM doesn't do "master"-type communications, it doesn't use the subnet mask or gateway address. Whatever talks to the ECOM will be using IPX or UDP/IP, and the ECOM simply swaps the destination and source addresses in the telegram and responds in this way, not "caring" about the subnet or gateway. However, the ECOM100 acts more like a conventional TCP/IP device. The ECOM100 has the capability to be a master and has a full-blown TCP stack inside. Thus, if it is to transmit to an IP address not on its subnet, it will, of course, transmit to its configured gateway address instead.
Q: Does NetEdit come with the CD in the H2-ECOM-START kit?
A: Actually NetEdit used to come on a disk that was inserted into the manual that came with the H2-ECOM-START kit. It was not on the CD. Now, however, NetEdit3 (our latest) is installed with DirectSOFT. And, of course, you can always download NetEdit3 from our website.
Q: Why would NetEdit list the same module twice or show duplicate entries?
A: We have found two reasons for this:

NetEdit FAQ0009 (see also DirectSOFT FAQ129; DS
Data FAQ0070; ECOM FAQ0030)
Q: Does the ECOM work with DHCP? Or does the PC's NIC have to have a static IP address in order to communicate with an ECOM?
A: The ECOM does not support DHCP addressing, (ECOM100s support DHCP). The ECOM must have a static IP address. However, the PC that is talking to the ECOM does not have to have a static IP address. Things to consider:
NetEdit FAQ0010 (see also ECOM FAQ0031)
Q: Trying to use PLC-to-PLC communications between ECOMs but we see broadcasts across the network; and our router won't pass the broadcast.
A: When the PLC performs an RX or WX instruction through an ECOM, the ECOM uses a broadcast packet to locate the slave ECOM with the DirectNET Node Number specified and perform the read or write transaction. These broadcast packets will increase network usage, and broadcast packets are normally filtered out by routers, bridges, etc. To work around these issues, NetEdit3 provides a way to configure the ECOM to use a point-to-point UDP/IP packet to perform the transaction.
Here is how it works: the RX and WX instructions in the PLC only allow you to specify a DirectNET Node Number as the slave identifier. This node number will be in the range of 1-90. In the ECOM there is a "Node Number - to - IP Address" mapping table. To get to it press the <RX/WX Node Map> button on the "ECOM Settings" tab.
For each slave ECOM you want to communicate with, find its DirectNET node number in the table and enter the needed network information. Once this information is in the table, any RX or WX instruction the ECOM processes for that slave will use the information in the table instead of a broadcast packet.
You can enter the addressing information manually, but, you'll find it much easier to use the <Find> button in the Add dialog to add slaves to the table. "Find" will scan the local network and locate all of the ECOMs. You then simply pick the slave ECOM from the list and click <OK>; the required information for the table entry will be automatically generated.

Q: Getting various errors when attempting to use NetEdit to see or establish a link to a Host Ethernet device.
A: Here are know errors and their suggested solutions:
CAUTION: You may want to consult your Network Administrator before doing any of the solutions below! He/she may not want you to change your PC's setup at all!
(5) "Error reading
configuration values from device."
First of all, there was a bug in versions of NetEdit previous to v3.1, that when you pressed the Query Network button this error could pop up. If this is the case then you just need to download a later copy (at least v3.1) of NetEdit from our website. If this is not the case then notoriously, this error is caused by one of the following:
If none of these things fix the
problem, then it is possible that the EBC/ECOM/EDRV/ERM/EZ Ethernet
device is defective and you may need to send it in for repair.

Q: What Ethernet protocols are used by your products?
A: Refer to chart below:
|UDP/IP||IPX||TCP/IP||Raw Ethernet Broadcast (1)|
|K-seq||DirectNet||ECOM (2)||Koyo Backplane||User Defined Data||Proprietary (1)||K-seq||DirectNet||ECOM (2)||Proprietary (1)||Modbus TCP Master||Modbus TCP Slave||Proprietary (1)||Koyo Backplane|
|Hardware||ECOM||ü||ü||ü||ü (3)||ü (4)||ü||ü||ü||ü (5)|
|ECOM100||ü||ü||ü||ü (3)||ü (4)||ü||ü||ü||ü (6)||ü||ü (5)|
|ERM||ü (7)||ü (7)||(8)|
|Ethernet SDK||ü (9)||ü||ü||ü (9)||ü||ü|
|NetEdit||ü (10)||ü (11)||ü (10)||ü (11)|
Not an industry standard. However, protocol is available for 3rd-party
development upon request.
(2) Not really a distinct protocol. This setting is used to intelligently pick K-sequence or DirectNet as needed by the hardware/software.
(3) Used when doing ECOM-to-ECOM via RX/WX instructions with RX/WX Node Map configured in sending ECOM.
(4) Used when doing ECOM-to-PC (Report-by-Exception) via RX/WX instructions (Address 90 only) with ECOM's dipswitch 7 set ON.
(5) Used when doing ECOM-to-ECOM via RX/WX instructions without RX/WX Node Map configured in sending ECOM.
(6) RX/WX Node Map must be configured in ECOM.
(7) ERM can talk to one slave with UDP/IP and another with IPX simultaneously.
(8) Planned for Dec2004-Feb2005.
(9) Requires K-sequence protocol spec (request from Automation Direct)
(10) Uses K-sequence to perform "Test CPU Access!" function.
(11) Uses this protocol to perform "Show Base Contents..." function.
(12) The older HA-EDRV2 cannot talk Modbus TCP.

Q: What software tool do I use to upgrade/downgrade my Host Engineering hardware?
A: Refer to the following:
|Host Hardware||Part Number||Firmware/Booter Upgrade Tool|
NOTE: All the firmware for the above products can be downloaded using NetEdit3's File --> Live Update... The firmware files are stored in c:\HAPTools\Images folder.
NetEdit FAQ0015 (see also EBC FAQ0054; CTRIO
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:
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.
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.
Q: When attempting to use Live --> Update feature, get "12029" error message.
A: A 12029 error is a firewall issue error. This means that one or more firewalls is blocking your attempt to open and/or retrieve files. Most of the time this can be attributed to your WinXP Firewall. Please follow these steps to add NetEdit3 to your WinXP Firewall's Safe List:
(1) Start --> Control Panel.
(2) Double-click on the Windows Firewall icon.
(3) Select the Exceptions tab.
(4) Press the <Add Program...> button.
(5) Use the <Browse...> button and add c:\HAPTools\NetEdit3.EXE to the list.
(6) Press <OK> button.
(7) Reboot your PC.
If the problem persists, your PC might have a secondary firewall in place. If so, you will also have to add NetEdit3 to its safe list as well.
Also if you are working from an office or you are using your company's PC or Internet connection, it is possible that your company has some type of network firewall in place. You will have to contact your company's System Administrator for what to do about this.

Q: How can I install IPX protocol for my NIC?
A: You can find instructions on how to do this for your particular operating system by going to Start --> Help & Support and searching for "Install NWLink." Below are the instructions from Microsoft for doing this on a WinXP PC. The instructions are similar for other operating systems (e.g. WinNT, Win98, WinME, Win2K).
To install NWLink IPX/SPX/NetBIOS
Compatible Transport Protocol
(1) Open Network Connections:
(a) Click Start --> Settings --> Control Panel.
(b) Double-click Network Connections.
NOTE: You must be a member of the Administrators group to install protocols. Also, when IPX is installed it is installed for all your connections. If you don't want it installed for a certain connection, then right-click that connection, click Properties and, on either the General or Networking tab, clear the NWLink IPX/SPX/NetBIOS Compatible Transport Protocol check box.
(2) Right-click a local area connection, then click Properties.
(3) On the General tab, click Install.
(4) In the Select Network Component Type dialog box, click Protocol, and then click Add.
(5) In the Select Network Protocol dialog box, click NWLink IPX/SPX/NetBIOS Compatible Transport Protocol, and then click OK.
IMPORTANT: The IPX/SPX protocol is not available on WinXP 64-Bit Edition, WinVista or Win7.
Q: How can I make a copy of the NetEdit display for my records?
A: If you have at least NetEdit v3.2, you can use the File --> Export feature which will export the display list to a .CSV file which can then be easily imported to Microsoft Excel.
NetEdit FAQ0019 (see also ERM FAQ0038)
Q: If my PLC containing an ERM is in the RUN mode, and I change the parameters of the ERM using NetEdit, they appear to change, but they are not actually getting written to the ERM.
A: This is a bug in NetEdit v3.2 or earlier. To fix, use at least NetEdit v3.2a or later.
Q: Can NetEdit be run on my PC as a stand-alone application without having to install DirectSOFT?
Q: Having various problems installing NetEdit3.
A: Primary things to check before consulting the errors listed below:
Below are various installation errors that have been encountered and their solutions.
NetEdit FAQ0022 (see also EBC FAQ0059; ECOM
FAQ0051; EDRIVE FAQ0013; ERM FAQ0040; EZ Ethernet FAQ0028)
Q: I inadvertently changed the IP address of my Host Engineering Ethernet device and now NetEdit cannot find it, nor can I ping it. How can I get it "back?"
A: It can be changed using IPX protocol:
Q: In the General Help window there are strange characters ("garbage" text).
A: This is a bug in some earlier versions of NetEdit3. Upgrading to the latest version will take care of this.
NetEdit FAQ0024 (see also ECOM FAQ0060)
Q: Using NetEdit with ECOM/ECOM100; in the Advanced Settings, what is the difference between "RX/WX Settings - Retries" and "KSequence Settings - Retries"?
A: "RX/WX Settings - Retries" is the number of times the ECOM/ECOM100 will attempt a comm over the network for an ECOM-to-ECOM (Peer-to-Peer) communication.
"KSequence Settings - Retries" is the number of times the ECOM/ECOM100 will attempt a comm over the backplane to the DL-PLC.
NetEdit FAQ0025 (see also ECOM FAQ0062)
Q: When using the ECOM100 as a Modbus TCP Client (Master) with the RX/WX instructions reading/writing to a Modbus TCP Server (Slave; e.g. ProSoft Technology module for Allen-Bradley PLC), keep getting timeout errors.
A: This could be caused by one or both of the following issues:
NetEdit FAQ0026 (see also DirectSOFT FAQ0197;
Q: When using NetEdit v3.6b (or earlier), the ECOM/ECOM100 won't pass the CPU Test, but I can still make and use a link from DirectSOFT.
A: This was caused by NetEdit v3.6b (and earlier) using a slightly different method to test for CPU than DirectSOFT. This was fixed in:
NetEdit 3.6c (and later)
NetEdit FAQ0027 (see also ECOM FAQ0083)
Q: If my Modbus TCP client (i.e. master) does not talk to the ECOM100 faster than 5 seconds, the ECOM100 closes the TCP connection and I have to open up another one.
A: This is a problem with the firmware in the ECOM100. In earlier versions of the firmware the ECOM100 had a Modbus TCP server (i.e. slave) timeout value fixed at 5 seconds. This, however, was changed with:
H0-ECOM100 v4.0.154 (or later)
H2-ECOM100 v4.0.1185 (or later)
H4-ECOM100 v4.0.1185 (or later)
With these later versions the default Modbus TCP Slave Timeout value is 20 seconds. But also, NetEdit was changed to allow this timeout to be adjusted to whatever you want. This feature was added to:
NetEdit FAQ0028 (see also EBC FAQ0091; ECOM FAQ0085; EDRV FAQ0031)
Q: My ECOM100/EDRV100/EBC100 disappears from NetEdit using TCP/IP protocol if I accidentally give it a bogus IP address, or gateway address, or subnet mask.
A: This has not been a serious problem until the advent of WinVista. The reason being that you normally could switch to IPX in NetEdit and find the Ethernet device and then fix the mistake. However, with the advent of WinVista, IPX is no longer available. Thus, the following changes were made to the ECOM100, EDRV100 & EBC100 firmware and NetEdit to alleviate this issue:
These fixes are in:H2-EBC100 v4.0.490 (or later)
NetEdit FAQ0029 (see also ECOM FAQ0086)
Q: Is it possible to test the e-mail function and configuration of the ECOM100 using NetEdit?
A: Yes, this feature is available with:
H0-ECOM100 v4.0.167 (or later)
H2-ECOM100 v4.0.1237 (or later)
H4-ECOM100 v4.0.1237 (or later)
It is on the right-click menu in NetEdit (or on the ECOM Settings tab under Utils along with the Test CPU Access).
NetEdit FAQ0030 (see also EBC FAQ0075)
Q: What are the meanings of the Port Mode settings for the EBC/EBC100 that are seen in Serial Port Settings of NetEdit?
A: The functionality and description of these modes are not documented anywhere simply because there are no products that fully utilize them. Basically the EBC has 2 Port Modes (Master/Proxy; K-Seq Slave) and the EBC100 has an extra 3rd one (Modbus Slave). These modes are briefly described here:
NetEdit FAQ0031 (see also PSCM FAQ0002)
Q: How do I update the firmware or booter for my H0-PSCM module?
A: On the top of the H0-PSCM module there is an RS232C RJ12 serial port connector. It can be accessed by opening the little door for that slot in the DL05 or DL06. The port is identical to an RJ12 serial port on the DL PLCs. To perform the update:
NetEdit FAQ0032 (see also EBC FAQ0076;
ECOM FAQ0092; EDRV FAQ0023; ERM FAQ0050; )
Q: Can firmware upgrades be performed over a remote network (e.g. over the Internet)?
A: Not normally, no. The reason is because NetEdit must be able to see the Host Ethernet device in his list. The list is compiled by NetEdit sending out a broadcast and having all the Host Ethernet devices respond. Since the Internet will block all broadcasting, then the list will always be blank. However, it is possible to configure a VPN (Virtual Private Network) between the locations and configure the VPN in such a way as to allow broadcasting.
Q: What Windows operating systems does NetEdit work with?
A: See the following chart:
|Windows Operating Systems|
(1) - Have not tested officially but probably will work.
(2) - Both 32-bit and 64-bit versions work.
(3) - Win8-RT version not supported.
NetEdit FAQ0034 (see also EBC FAQ0077;
ECOM FAQ0102; ERM FAQ0051; SDK FAQ0019)
Q: How can I enable the "fast response mode" of the T1F-08AD-1 or T1F-08AD-2?
A: The fast response mode of these devices is activated by a write to a special location in the T1H-EBC or T1H-EBC100 called Config Data. This area of memory is not available to the ERM nor NetEdit and therefore cannot be configured with ERM Workbench, nor NetEdit.
If using T1H-EBC:
- Currently, the only way to write to the Config Data of the T1H-EBC is to use the Ethernet SDK routine HEIWriteConfigData. The Ethernet SDK is free and downloadable from http://www.hosteng.com/Ethernet_SDK.htm.
If using T1H-EBC100:
- Currently, there are 2 ways to write to the Config Data of the T1H-EBC100:
(1) Use the Ethernet SDK routin HEIWriteConfigData. The Ethernet SDK is free and downloadable from http://www.hosteng.com/Ethernet_SDK.htm.
(2) Use Modbus TCP. The Config Data is mapped into the Modbus TCP memory range 50021-50052 (or 410021-410052 for 6-digit addressing). This range is 32 words (1 word for each slot). The bits of the word are defined as follows for the analog input cards:
Bits 0-4: 0 = All channels enabled; 1-31 = Number of channels enabled starting with channel 1
Bits 5-6: Reserved
Bit 7: 0 = Normal response; 1 = Fast response
Bits 8-15: Reserved
NetEdit FAQ0035 (see also ECOM FAQ0107)
Q: Is there any way to protect the HTML configuration on the ECOM100 to make it Read only (Write protected)?
A: Yes. This capability was added to the following firmware:
NOTE: This feature cannot be changed with the HTML editor. The setting can only be configured with NetEdit v3.7c (or later).
NetEdit FAQ0036 (see also ECOM FAQ0108)
Q: Is there any way to force the ECOM100 to use 10 Mbps transmission rate instead of the 100 Mbps?

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.
NetEdit FAQ0038 (see also ECOM FAQ0100)
Q: Can the ECOM100 send e-mail via my public ISP account (e.g. Gmail, Juno, AOL, Charter, etc.)?
A: Most of the time this will not work, mainly due to the ISP's security measures and the fact that many web-based e-mail services are not able to be accessed via SMTP protocol.
Basically, the ECOM100 was not designed to send e-mail in this fashion, but rather, was designed to send e-mail to an e-mail server on its own local area network. However, if you do not have a local area network e-mail server available then:
The 1st thing to try is:
(1) Put a PC on the ECOM100's local network.
(2) See if you can setup your PC's e-mail (e.g. Microsoft Outlook) to get e-mail from your 3rd-party ISP. Your IT personnel will have to help you with this; as Host Engineering nor the techs at Automation Direct can help you with this.
(3) If you and your IT personnel can read e-mail from your 3rd-party ISP this indicates you have at least an open channel to your ISP's e-mail server.
(4) Attempt to send an e-mail using this PC's setup. This is vitally important.
If the PC's e-mail send does not work, then you will not be able to get the ECOM100 to do it either.
If, however, the PC's e-mail send
works using the 3rd-party ISP setup, then there is a slight chance you
can get the ECOM100's e-mail send to work by:
(1) Using the same Server IP Address setting on the ECOM100 as was used in your PC's setup.
(2) Using the same Sender EMail Address setting on the ECOM100 as was used in your PC's setup.
(3) Using the same SMTP Port number on the ECOM100 as was used in your PC's setup.
(4) Using the same Authentication Username and Password on the ECOM100 as was used in your PC's setup.
NOTE: The ECOM100's e-mail Authentication setup is currently only configurable via the HTML setup page of the ECOM100 (i.e. use a web browser like Internet Explorer, Chrome, Mozilla, etc. and type in the IP address of the ECOM100 to access). Also, another show-stopper is the fact that the ECOM100 only uses one form of e-mail authentication whereas your ISP may use something different.
So, the odds of getting this to work are very slim, but it is sometimes possible.
NetEdit FAQ0039 (see also ECOM FAQ0110;
Q: When setting up E-mail for the ECOM100, is it necessary that the SMTP Server IP Address be a "name" instead of a static IP?
A: No, this is not possible. This would require that the ECOM100 support the DNS protocol, which it doesn't. Instead the ECOM100 was designed to send e-mail to an e-mail server on its own LAN which normally has a static IP address.
If all you have is a name to work with, then you can find the static IP by doing the following:
Replace, <name> with your e-mail server's DNS name. When this is executed, you will see something like:
Pinging <name> [<IP Address>] with 32 bytes of data:
Reply from <IP Address>: bytes=32 time=205ms TTL=55
Reply from <IP Address>: bytes=32 time=254ms TTL=55
Reply from <IP Address>: bytes=32 time=215ms TTL=55
Reply from <IP Address>: bytes=32 time=266ms TTL=55
Ping statistics for <IP Address>:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 205ms, Maximum = 266ms, Average = 235ms
The IP address contained in the brackets after the server's DNS name is the static IP of your e-mail server.

FAQ0086, EDRV FAQ0029, ERM FAQ0060, EZEthernet FAQ0032)
Q: What do the Ethernet Stats at the bottom of NetEdit specifically mean?
A: These are stats that are reported up to the firmware from the hardware communication components. They are technically defined as:
Missed Fr - "Missed Frames" - A count of the packets missed due to overruns, unavailable buffers or a disabled receiver.
TX Coll - "Transmit Collisions" - A count of the packets which had a late collision while being received.
Lost Pkts - "Lost Packets" - A count of the packets discarded because they were too long or too short.
Bad Pkts - "Bad Packets" - A count of the packets which have bad CRCs (checksums).
Unknown - A count of the packets which contain invalid symbols, extra bits or resulted in a receiver overrun condition.
TX Errors - "Transmit Errors" - A count of the packets which could not be sent because the transmitter was unavailable for an extended period of time.
