Product Details

1C31227G01 core controller module


1C31227G01 is a core controller module developed by Westinghouse (now integrated into Emerson Automation Solutions) for its Ovation Distributed Control System (DCS). It serves as the "brain" of the Ovation DCS, responsible for executing control logic, processing real-time data from I/O modules, and coordinating communication with upper-level systems—critical for ensuring stable and precise control of industrial processes in harsh environments like power plants and petrochemical sites. Below is its detailed information:

1. Core Technical Specifications

Parameter CategorySpecific Details
Processor & Performance- CPU: High-performance 32-bit industrial-grade processor (frequency ≥500MHz), supporting parallel execution of multiple control loops.- Control capacity: Up to 4096 I/O points (analog + digital) and 1024 control loops (e.g., PID, cascade control), meeting the needs of medium-to-large industrial processes.- Memory: 256MB RAM (for real-time data processing) + 512MB flash memory (for storing control programs and configuration files), supporting data retention without power for ≥72 hours.
Supported Control Logic- Native support for standard control algorithms: PID (proportional-integral-derivative), cascade control, feedforward control, ratio control, and interlock logic.- Custom logic: Compatible with IEC 61131-3 programming standards (e.g., ladder diagram, function block diagram, structured text), enabling flexible customization for complex processes.- Real-time performance: Control cycle as short as 10ms (for fast-response loops like boiler pressure control), ensuring timely adjustment of process parameters.
Communication Interfaces- Backplane communication: Ovation proprietary high-speed backplane bus (data rate ≥100Mbps), connecting to I/O modules (e.g., 1C31194G03, 1C31201G01) and power modules (1C31234G01) for real-time data exchange.- External communication: 2 Ethernet ports (RJ45, 10/100Mbps adaptive) for connecting to Ovation HMI, engineering workstations, or upper-level SCADA systems; supports protocols like Modbus TCP, Ethernet/IP, and OPC UA.- Diagnostic port: 1 RS232 port (DB9) for local configuration, program download, and fault troubleshooting.
