FOXBORO CP40 Product Brief Description

The FOXBORO CP40 is a high-performance control processor for Foxboro I/A Series DCS distributed control system. It serves as the core computing unit of the control node, executing real-time PID closed-loop control, interlock protection, sequence logic and batch control algorithms. It communicates with FBM field bus I/O modules over the fieldbus and exchanges process data, alarms and trend information with operator workstations via the plant mesh network. It supports simplex or fault-tolerant redundant pair deployment for high availability in critical process units.
