Hello everybody, what would be the best method to connect a redundant GW setup to a pair of siemens redundant S7-1500R?
I’ve seen a few posts where people configured 3 plc connections (PLC_MASTER, PLC1 and PLC2) and wrote a script that detects a loss of communication with PLC1 or PLC2 and change the IP adress of PLC_MASTER.
I am also thinking of adding a third party OPC server like Kepware on each GW PC.
Other option… WinCC
I would appreciate hearing your opinion and thoughts on this
