Connection paths

Ignition
1

good morning everyone.

I have a question related to setting up a path to connect one PLC to our ignition gate way. my main PLC has:
1756-EN4TR (IP 10.129.0.2)card slot 2
1756-L83ESK (IP 10.128.208.197)slot 0.
remote PLC to where i want to connect is compact Logix (IP 10.129.0.18)
Can you guys give any idea how to create a path?

  1. Select the appropriate driver for the PLC that you ultimately want to connect to, depending on firmware.
  2. Set the Host Name to the IP address of the Gateway Controller (10.128.208.197)
  3. Set the Connection path to something like:
1,2,2,10.129.0.18

You may also need to append the appropriate port number to the end of the connection path ( I can never remember when it's needed and when it isn't). It will be either 2, or 3 depending on what model of CompactLogix controller you are using and how you have configured the ethernet ports in the controller.

There is actually pretty good documentation about this in the manual, though no example for your exact configuration. Fairly simple to make the leaps you need to get it going though.

thanks for responding.
so you are saying that hostname should have the IP directly connected to the Server? I just tried this IT populated all the tags on my Main PLC (not the ones from 10.129.0.18)
Yes, there is a good amount of information, but I am doing something wrong.

Yes.

I think the problem here is most likely due to trying to use the controller as the main connection to the network.

I don't have enough knowledge to know that for sure, but I think you may need another Ethernet module.

@Kevin.Herron might be able to better answer.

Perhaps swapping the Ethernet card in Slot 2 and the controller's IP addresses would work, of course you would need to alter the path appropriately as well.

That's what you get when you omit a connection path. Did you put the recommended connection path into that device's settings?

6

Yes, I placed the connection path. I tried the recommended one and also some variants according to the literature.

thank you for the help, hope I don't need other ethernet module.

Irose, thanks for your help, I found what I was missing this was the correct path: 1,0,2,10.129.0.18,1,0 however, It did not populate my tags divided by program from my ladder logic, it just gave me a list of tags. do you guys think that I am using the wrong ignition driver?

No, that's normal for programs that use mostly (or entirely) controller-scope tags. (Necessary for multiple programs to share data, so fairly common.)
