Working Principle: After the system is powered on, the main processor module initializes the system program and completes handshake communication with all I/O modules in the rack. The module cyclically collects all field sensor signals and operating state data, executes preset control algorithms and protection logic, and outputs accurate control commands to field actuators. The module monitors the operating state of the entire rack in real time, automatically records fault codes and event records when abnormalities occur, and maintains system stable operation through self-recovery mechanisms.
Installation Requirements: Insert the processor module into the dedicated CPU slot of the control rack Ensure complete docking and locking of the backplane bus interface Guarantee reliable grounding of the control cabinet to ensure equipotential balance Reserve sufficient heat dissipation space around the module to avoid overheating Complete system program configuration and bus address matching after installation Carry out full-system debugging to verify communication and control functions
Precautions for Use: Must cut off the total power supply of the rack before disassembly and assembly Strictly implement anti-static protection during maintenance Prohibit random modification of internal system program and core parameters Avoid strong vibration and impact on the module during operation Regularly check bus connector contact status to prevent poor communication Prevent cabinet humidity overload and condensation corrosion
