ControlLogix: Extract IP address from Ethernet/IP module

I have a program that has a lot of message instructions. Sometimes, I need the user to select to route those message instructions to a different device. Until now, I've hard-coded the two possible paths into some strings and written the one I needed into the message instruction path.

But now I've hit a situation where hard-coded paths may not work. However, if I could extract the IP address from a module (someone else will configure it), then I could populate the MSG paths from there. The program will be more flexible, and I'll spend less time supporting it.

Has anyone found a way to get the IP address out of a profile module?

Another option would be to allow the program to update the Module's IP address.

Thanks in advance for any thoughts and suggestions!

Thanks John!

You're welcome. I looked into actually changing an EN2T IP address with program logic. It seemed too involved to do and I didn't what to trust it in the field.
