Working Principle After power on, the CPU module executes comprehensive self-test. Dual independent processors run identical safety program and cross-check calculation results every scan cycle. The module exchanges input and output data with distributed I/O modules via safety backplane bus. When safety trip condition is satisfied, the CPU sends command to I/O modules to de-energize safety outputs. Watchdog circuit monitors processor operation continuously. If mismatch or program halt occurs, the controller forces all safety outputs to predefined safe state and records fault event.
Installation Requirements
- Install CPU module into HIMatrix F35 DIN rail rack.
- Use shielded twisted pair cable for safety network and serial service wiring.
- Separate safety communication cables from high-power motor cables.
- Complete rack protective earth connection.
