3. Working Principle

System Initialization & Parameter ConfigurationAfter power-on, the CPU automatically completes self-inspection and system initialization, and detects operating status of internal units, backplane bus and connected I/O & communication modules. It enters ready state after confirming normal operation. Engineers download control programs compiled with IEC 61131-3 standard languages into the CPU via Unity Pro, and configure communication parameters, I/O addresses, redundancy modes and protection thresholds to finish system matching.
Signal Collection & Command ReceptionConnected with I/O modules via backplane bus, the CPU collects real-time analog and digital signals from on-site sensors and actuators such as temperature, pressure, flow rate and equipment status. These signals are filtered and calibrated into recognizable digital data. Meanwhile, it receives control commands including parameter adjustment and equipment start-stop instructions issued by upper computers and remote terminals through communication interfaces.
Logic Operation & Control OutputAccording to preset control programs, the CPU conducts complex logic calculation, arithmetic operation and process analysis on collected field signals and received commands, generates control signals and sends them to I/O modules via backplane bus to drive on-site actuators such as valves, motors and indicators for precise production and equipment control. Built-in algorithms realize closed-loop adjustment of process parameters to guarantee stable production.

Redundant Control & Fault HandlingUnder dual hot standby configuration, primary and standby CPUs synchronize programs, data and operating status in real time. Once the primary CPU fails, the standby one will take over system control automatically within 100ms to avoid production interruption. During operation, the CPU monitors its own status, bus communication and I/O module status in real time. It triggers fault alarms, lights corresponding indicators and uploads fault information to upper systems for rapid troubleshooting. The built-in lithium battery preserves memory data to prevent program and data loss after power failure.

Data Interaction & Remote MaintenanceVia Ethernet, serial ports and fieldbus interfaces, the CPU uploads on-site data, equipment operating status and fault information to upper computers, and receives remote control commands and parameter settings. Engineers can remotely monitor system status, modify parameters and update programs through upper computers to complete debugging and maintenance without on-site presence, greatly improving work efficiency.
