Most of what I know about configuring MSG instructions I've learned from reading answers to people's problems on this site
This particular issue has at least some documentation under the MSG instruction in the Logix5000 Controllers General Instructions Reference Manual, specifically the 'Specify the Communication Details' section.
Wow, thanks. That section of the manual is both vague and profoundly flexible at the same time; apparently almost every AB device is a router; all you need to know is how it is configured. I wonder if there are more than a few dozen people on the planet who fully comprehend this, or if everyone goes by trial and error or finding someone who did summat similar.
It is just like uunet.
