Technical Specifications

Function Description

The 900C32-0140-00 module is used as the core control processor in HC900 systems, responsible for managing all automation and process logic tasks.

Its main functions include:

• Executing PID control loops for industrial processes
• Running logic, sequencing, and interlock programs
• Managing real-time input/output data processing
• Coordinating communication with I/O modules
• Handling alarms, events, and system diagnostics
• Supporting SCADA/HMI integration

Working Principle

The controller operates as a continuous closed-loop control processor:

1. Field devices send signals via I/O modules
2. The CPU receives real-time process data
3. Control algorithms (PID, logic, sequencing) are executed
4. Output commands are generated based on system conditions
5. Commands are sent to output modules and field devices
6. The cycle repeats continuously for stable process control

This ensures precise and deterministic control of industrial processes.
