We have a PV1000 connected to a ControlLogix. The PV has two Serial ports. "RS 232 DF1" and "RS 232". The ControlLogix is connected to the "RS 232 DF1"-port. What's the use of the "RS 232"-port? I tried to get comms with both the PLC and the PV similtaniously, but it doesn't work. I have to disconnect one to get to the other.
So what is it there for?
