- Coordinating output commands to safety actuators
- Performing continuous system diagnostics and self-checks
- Managing communication across FSC system modules
- Ensuring fail-safe operation in abnormal conditions
It is the core decision-making unit of the FSC safety system.
Working Principle
The module operates within a fail-safe control architecture:
- Field sensors and safety devices send signals to input modules
- Input data is transmitted to the FSC CPU module
- The CPU continuously evaluates safety logic conditions
- If a hazardous condition is detected, safety actions are triggered
- Output modules activate shutdown devices or alarms
- The system continuously performs self-diagnostics to ensure reliability
The design ensures that any internal fault leads to a safe system state.
