Monitor Ethernet Channel Messages Recieved

[ryanAstiefes]

I would like to monitor my M340 Ethernet Messages. I can view them while connected to the controller using Control Expert but would like use them in some logic. Attached is the Messages I would like to use.

I added the ethernet port to a IODDT and can see some of the status words/bits but not the messages recieved. I've attached the IODDT.

Is there a way to view these messages in my logic?

Hello,

The message that you refer is the TAG COMMENT and cannot be used in the logic, it is only for information propose.

How would I go about monitoring Modbus TCP transactions?

Hello,

What info do you need?

When communicating with my SCADA system I would like to view transactions between the two to verify communication integrity. If communications are lost due to a PLC comm fault I would like to reboot the PLC. I guess I could do a heart beat circuit if this option is not available.
