Working Principle
Communicates with field I/O modules via a high-speed bus, processes real-time data using built-in advanced control algorithms, and transmits control results to the execution and supervisory layers through redundant Ethernet.
Installation Requirements
- Must be securely locked into dedicated control rack slots.
- Ensure stable 24VDC redundant power supply.
- Avoid installation near strong interference sources such as variable frequency drives.
Usage Precautions
- Always wear an anti-static wrist strap before handling the module.
- Strictly prohibit operation in environments exceeding temperature or humidity limits.
- Never disassemble internal components of a faulty module independently.
