IV. Working Principle
Power-on Initialization & Self-test: The CPU receives 5VDC power from rack backplane and automatically completes hardware self-check, core initialization, flash firmware loading, RAM verification and communication port detection after power-up; it enters RUN or STANDBY mode once no hardware faults are confirmed.
Program Loading & Execution: User programs, process parameters and system configurations are loaded from flash and backup RAM. Following cyclic scan logic, the CPU sequentially executes instructions for logic computation, sequence control, mathematic calculation, PID regulation and interlock judgment.
I/O Backplane Scheduling & Data Exchange: Via high-speed Series 90-70 VME backplane bus, the CPU periodically polls all I/O modules to collect discrete and analog field signals and outputs control commands to respective output modules for on-site equipment regulation.
Multi-channel Communication Data Exchange: RS232 and RS485 ports establish links with programming terminals, upper-level SCADA systems, field instruments and interlocked equipment to upload runtime data, receive control orders and synchronize process parameters in real time.
Data Storage & Power-fail Protection: Critical runtime data, recipe parameters and equipment status are cached into battery-backed RAM during operation. The onboard backup battery sustains RAM power during unexpected blackouts, while core firmware is permanently stored in flash to avoid data loss and system crash.
Fault Monitoring & System Safeguard: Real-time monitoring covers hardware status, bus communication, program execution and port conditions. Upon program exception, bus dropout or hardware failure, the unit triggers fault alarms, freezes operating status or initiates safe shutdown to protect the whole control system.
System Expansion & Collaborative Processing: Compatible with diverse expansion modules to add Ethernet communication, high-speed counting, redundant control and coprocessing functions for implementation of sophisticated large-scale automated control workflows.
