Check the position of those switches as well, assuming they exist on this particular module.
Yep, I made this post before I had dug into the manual and indeed the first time i used BOOTP i had skimmed and didnt' see the part about disabling DHCP!! all is well now. Next is to actually get the Delta V controller controlling it. But, the PLC side of things seem to be resolved.

Well done. Persistence pays off and the challenge is always half the fun (at least for me). Glad you got it working.
