Foxboro P0960AW CP30 Control Processor Module I/A Series DCS

The Foxboro P0960AW (CP30) is a rack-mounted control processor module designed for the I/A Series Distributed Control System (DCS). As the central processing unit of a control node, the CP30 executes regulatory control logic, sequential operations, and manages communication with Fieldbus Modules (FBMs) over the redundant Module Fieldbus. The CP30 serves as the "brain" of the I/A Series rack, running PID loops, Boolean logic, timers, and data acquisition tasks while maintaining high-speed communication with operator workstations and application processors via the Nodebus. Its architecture supports redundant configurations, ensuring uninterrupted process control even during hardware faults. This processor is widely deployed in continuous process industries including oil and gas, power generation, chemical processing, and water treatment, where reliability and deterministic control performance are critical.
