I am using a Controllogix processor with a DHRIO card to talk to a 1794 ASB. The ASB rack has 4 analog input cards. I have them programmed the MSG for the analog inputs and they are working correctly.

The problem is with the 1794-OF4I MSG instructions.
How long is the read instruction?
How long is the write instruction?
Do I need to have any additional information in the write instruction?

I can not find programming examples for RSLogix 5000.

Thanks
