Hello all,
I have been designing Functional Safety systems with Safety Relays, but for a new system I might consider a PLC as there are additional I/O requirements.
My questions are:
1. Can a safety-rated PLC replace safety relays - can they do pulse testing of emergency stop circuits?
2. Does monitoring of force-guided contactors have to be programmed separately?
3. Does anyone have experience using OPC-UA to interface with Python to read inputs and set outputs from a PLC?
