I have a project coming up with a M580 cpu with a NOC0301 card.
The majority of the comms will be EIP, which I'm familiar with, but I will have some devices that are Modbus TCP. I have never used modbus in 30 years of programming, so I am looking for some help getting the device setup in ControlExpert (only my 2nd project with SE). The only device I have on hand to test MTCP is a cognex barcode scanner. I know it will do EIP, but I'm trying to stay ahead of this project by learning how to setup MTCP.
Attached are pics of what I have, no matter what I've done so far, I cannot get the Freshness bit to come true, or get any data from the BCR.
My current Connection is ID(255), Read (0) Len (2), Write (0) Len 2.
Any help or insights would be appreciated.
Thanks.
