I have installed the Allen-Bradley Driver module and OPC UA module. I believe all of my 20+Allen-Bradley Contrologix PLC's are communicating through the AB Driver. I am also using UaExpert to pull data to a different server. My client and server opc ua certificate expired on 11/18/2024 on Ignition server and the UaExpert stopped working. If I regenerate the server and client certificates, will it affect 1) comms to plc's 2) Ignition clients in field being able to connect back to server.
I think you have to restart at least the OPC UA module if not the whole Ignition Gateway after re-generating them, so that will have some effect.
Restarting the module will interrupt comms to your devices.
Restarting the Gateway obviously interrupts everything.
