IV. Working Principle

Power-on initialization & self-test: After energization, the module automatically executes hardware diagnosis, flash medium inspection, communication port verification and fieldbus protocol matching. Once storage units, communication links and power supply are validated normal, it completes bus handshaking with the master CPU and enters standby mode.
Extended system storage service: During regular operation, it acts as an external high-speed storage medium for the master CPU to store large user programs, process formulas, PID setpoints and operational logs, easing main controller storage load and improving overall program execution and data access efficiency.
Real-time intelligent data validation: Continuous online check of stored data identifies and isolates faulty flash blocks automatically to correct data deviation, while critical runtime information is cached in real time to secure data integrity and precision.
High-speed fieldbus data exchange: It establishes PROFIBUS DP/V1 links with field smart instruments and remote I/O modules to upload acquired field data and download control commands from the master CPU, expanding available communication channels and system transmission bandwidth.
Power-fail automatic data solidification: Upon unexpected power loss or equipment breakdown, the module instantly triggers data lock-in logic to permanently write runtime parameters, process status and interlock configurations into flash memory for quick data synchronization and system recovery after power restoration.
Data backup & restore for maintenance: Supports automatic system backup and manual user backup; one-click restoration from archived data shortens downtime and commissioning periods when programs or parameter configurations get corrupted.
Real-time synchronization with main controller: Constantly synchronizes operational status, stored datasets and communication parameters with the host CPU to assist logic computation, closed-loop regulation and equipment interlock, guaranteeing stable, efficient and uninterrupted operation of the whole automation system.
