I have an OPC server running that signals when a break is happening for the shift. The OPC servis and the PLC are both connected to our Ignition SCADA software. I want to have my PLC be aware of when a break is happening to perform different functions (i.e. turning a light a different color). I'm aware that Ignition can write to the PLC tags directly, but I don't want to have to send out a status signal for every PLC when we start getting more systems running. I would rather have the PLC "ping" the OPC tag to get the status.
Is there a way for a PLC to read an OPC server tag?
I'm running a CompactLogix L16ER PLC with no extra modules.
Thanks!
