I am having issues getting Netedit 3 to recognize my ECOM 100 card in a DL06. All of the dip switches are set to 0 which I believe means that module ID assignment would come from the software. I have read that Netedit uses a broadcast to locate modules on the subnet by virtue of a broadcast will not traverse a router. I thought that this may be the reason that I could not see the card. However, when I connected my laptop directly to the card with a crossover cable, I still can not see the card in Netedit despite getting link, 100 Mbps and activity indications on the card. The PLC display registers the module fine in Slot 1. I have tried the crossover connection direct to the card using both Vista and Windows 7 but get nothing when I scan the network. About the only thing that I have not tried is disabling the Windows FW but thought I would bounce this off of some experts first. Any ideas on what I may be doing wrong or do I have a bad card? Thanks for any advice or suggestions.

I forgot to mention in my original post that I disabled all of the other network interfaces, leaving only the hard wire interface to the ECOM active during the scan.

If you are trying to use IPX, disabling the other adapters doesn't always disable them. It's a Windows networking quirk. Go into each adapter and uncheck the IPX protocol except for the one that you are trying to use.

As he is using Vista and Win7, he may not have IPX even installed...

bfitz,
You are correct - IPX is not installed. Just IP. I am going to try and set a module ID with the dip switches when I get home to see if that has any effect and I will report the results.
Thanks

Well, I tried setting a module ID via the DIP switches, disabling the Windows FW and even tried a different slot in the DL06 - all to no avail. Any other ideas that anyone can think of? Appreciate any insight.

The problem boils down to two concurrent problems: A) You don't have IPX installed on your laptop, which removes that communications option from the table and B) the ECOM does not have a reachable IP address.
Solving A on Vista or Win7 looks like it would be a real treat.
Solving B has a few different solutions.
I _assume_ that you are not on a network with a DHCP server. From my understanding, the ECOM is factory set to look for a DHCP server and request an address be assigned. Your NetEdit software should have found an ECOM that had an address by this method. If you want to go this route, you could download a DHCP server program to your laptop and set it to distribute addresses to clients. Then reboot (cycle power) on the ECOM while connected and it should receive an IP address. As long as the network adapter in your laptop has an address from the same network, it should be able to talk to it.
Another option is to use the serial link and some ladder to assign an IP address to the ECOM card. See the Ibox manual supplement for usage. If you go this route, you will not need to (or be able to permanently) set the IP address of the ECOM through the NetEdit software. When the Ibox is retriggered, it will overwrite the NetEdit settings with the pre-programmed values.
A third option would be to try to use the arp command on your computer to link an IP address to the MAC address of the ECOM card. I have not tried this and don't know if it would work, but you could give it a try. This website details the command and its usage. You may have to delete the arp listing when you are finished with NetEdit (it shouldn't be needed anymore). Note that this method only associates an IP address with a MAC address for YOUR computer. It only updates the local arp tables, so other devices will not be able to make the connection. The attraction to this option for me would be: no software to download and install; and no permanent IP address config in the ladder. Permanent config in the ladder may be a benefit to you, however.
Hope that gives you some options to choose from. Let us know if you still have trouble.

Bfitz,
You are the man! Using the Ibox to configure the card worked like a champ. Once I statically assigned an IP, everything works like it should and I can see the card in Netedit, etc. Thank you very much for your help and guidance. Hopefully I will be able to return the favor one day.

No problem, glad I could help. Good luck with the rest of your project.
