- Coordinating communication between I/O racks and SCADA systems
- Handling alarms, interlocks, and system states
- Supporting distributed control architectures
- Maintaining continuous industrial process regulation
Working Principle
The module operates as a real-time control processor:
- Field devices send signals to I/O modules
- I/O data is transmitted to the CPU module
- The CPU executes configured control logic
- Outputs are calculated based on process conditions
- Commands are sent back to field devices via output modules
- The cycle repeats continuously for stable process control
This ensures deterministic and reliable automation performance.
