Is there a way to link an input and output? I have an IRC5 control that has the CI502 option with ProfiSafe network. I have two dual channel door switches going into that. I would like tie those inputs to a digital output going to my external PLC through the ABB Anybus EIP option for monitoring.

Yes, it is called a cross connection.
