Thanks for the reply...
I tried to change the RPI to 250ms, but it doesn't change the error. Still Code 16#0203. Is there some config on the controller end or RSLinx that I can't find, which needs to match the IO RPI?
When I first set this up, the AENT also had the same error, until I changed the Electronic Keying to Compatible Keying, but that doesn't seem to help with the IO modules. I've tried Compatible, Exact Match, and Disabled on the IO modules, but no effect on the comm error.
Thanks again... I've been pulling my hair out over this...
