Schneider Electric / Invensys / Foxboro P0961FR Control Processor CP60 Module

The Schneider Electric / Invensys / Foxboro P0961FR is a Control Processor 60 (CP60) module engineered for distributed control within the Foxboro I/A Series DCS. This 32-bit processor executes regulatory, logic, timing, and sequential control algorithms at 100 MHz clock speed. It manages real-time data acquisition, alarm detection and notification, and bidirectional communication between Fieldbus Modules, field devices, controllers, and supervisory systems.

The module supports user-defined control strategies including PID and sequential logic, with 2 Mbps data throughput for inter-module communication.
