I have a project up with a Schnieder M580 PLC and with a BMENOC0301 card.
The majority of the comms will be Modbus TCP/IP.

I need to check Modbus TCP/IP comms as I am setting up a C-More CM5 to talk to it.

Does Control Expert any unique setup for Enabling Modbus TCP/IP?

I have tried to just show a few values to no success. (%MW4001, %MW4002, etc.)

I cannot see any values remotely via Modscan64.
Ask me questions and I will answer.
 
M580 has native modbus tcp support by default.
However you need to allow communications (cyber security settings, set IP and adjust variable ranges.
I think that by default there is some 1024 word variables (%MW0..%MW1023) so address %MW4001 is not accessible by default.
