M580 Modbus communication Woes

[Terry_Howsham]

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.

My IP Address is 192.168.6.3

Modscan64 sees this as a valid IP address.

Please check if the information below is correct

1) M580 PLC (BMENOC0301) = Modbus Slave, Modscan64 = Modbus Master
2) Is the ping test from PC running Modscan64 to BMENOC0301 normal?
3) If Modscan64 is Modbus Master, %MW4001 and %MW4002 data must be set as follows to read from PLC.

If you have the default security configuration for your NOC0301 then yes, the "Access Control" portion will stop communications from working. Try disabling that list or adding your computer's IP.

If you are trying to reach the first Analog Output. Try just %MW0001 and %MW0002, C-more might be offset by 1. I use AVEVA Edge 2023 with the Schne driver. It is exact, no offset. C-more is a very cheap and dirty (Notice, I didn't say robust) HMI. I would not recommend it.
