Transferring information over MPI network

[cartduty]

Hello All, I'm sure this will be simple for some of you, but I lack experience in this area. I have 8 CPU31x PLC's connected via MPI network. I want to create a DB to monitor a byte from each PLC from one "main" PLC. We are simply wanting to detect from one station, if there is a machine fault from any other station. Any ideas or advice would be appreciated!! Thanks! cartduty

Hello cartduty. For MPI, look into the blocks X_PUT and X_GET. Alternatively there is global data transfer: It does what the name says - provides a few datawords that are constantly transmitted and can be queried by all MPI nodes.

Thanks Jesper. I'll try it!
