Hi Dave,
Most of our examples are for Studio 5000, but it will be very similar in Logix 500. I did find an older example here:
Between that and the ‘Network Guide - Ethernet Slave’ and the ‘Reading/Writing data from Anybus X-gateway using ControlLogix MSG Instruction’ docs (https://www.anybus.com/support/file-doc-downloads/x-gateway-specific/?orderCode=ab7632) he should get a good idea of how to write the MSG instructions. Of course, he can always give us a call or ask us on HMS.how if he has any questions.
Thank you,
Kyle
