Hello all, first time, long time.
I'm new to the Siemens world and have latched on to a daunting project. I'm setting up an S7-300 plc with 2 remote IO racks and a WinCC Comfort HMI. For an added degree of difficulty it will also include having Software Redundancy.
My first question is, how do I set up module diagnostics? I have two IM-153s at each rack and will be using redundant IO. Rack 1 is primary while rack 2 is secondary. I need a way to determine the health status of each module and IO point so that I can use the logic to determine which IO point to use.
Unfortunately, this is not like the S7-400 so I don't think it can be done by simply using hardware redundancy.
Also, since I am using Software Redundancy, I have to use S7 Pro version 5.5 instead of TIA Portal. Please kindly advise if you have any pointers for me.
