Application Cases WESTINGHOUSE 1C31179G01
- Coal – Fired Power Plant: A utility deployed WESTINGHOUSE 1C31179G01 to connect its Ovation controller to 24 remote I/O nodes in a 500MW power plant. Redundant paths prevented communication loss during a network switch failure, avoiding a 6 – hour shutdown that would have cost $1.2M in lost generation.
- Petrochemical Refinery: A refinery used WESTINGHOUSE 1C31179G01 to link its Ovation DCS to remote I/O in a distillation unit. Auto – configuration cut commissioning time for a 16 – node expansion from 3 days to 8 hours, accelerating project completion.
- Water Treatment Plant: A water utility integrated WESTINGHOUSE 1C31179G01 into its Ovation system to control 12 remote I/O nodes across its treatment process. Built – in diagnostics detected a failing remote module, allowing replacement before a critical pump failure that would have disrupted water supply to 50,000 residents.
