Hey everyone,
Just wanted to see if anyone had any opinions on programming in a PLC that is essentially just being used to store data that's being written to it by another PLC? We have a lift station with a CompactLogix doing the control, but the spec called for a serial radio link back to the water utility, therefore the panel builder put in a MicroLogix 1100 to interface between the CompactLogix and the radio. I have all of the digital and analog I/O being written into the Micro from the Compact and have the I/O labelled, but what would you consider the bare minimum programming (if any) inside the Micro if it's not actually controlling anything? Would you include a comms heartbeat? Or something more elaborate?
Thanks in advance!
