Working Principle
The module acts as bidirectional data gateway: collects all I/O module real-time data on ACN backplane, packages data according to configured industrial communication protocols and transmits to upper DCS via Ethernet/RS485 ports. Downwardly receives control commands from host system, converts protocol format and distributes target instructions to corresponding rack I/O modules via internal ACN bus. Dual Ethernet ports implement seamless redundant switching when primary communication link fails.
Advantage Highlights
- Multi-protocol one-stop conversion eliminates additional external gateway hardware
- Dual redundant Ethernet ports ensure uninterrupted upper system communication
- High-speed backplane throughput supports full rack 32-channel synchronous data upload
- Hardware watchdog automatic fault recovery reduces system offline duration
- Universal compatibility with all Metso D2014XX, D2018XX, D2019XX series modules
- Compact single-slot design saves rack installation space
Applicable Industries
- Full spectrum of Metso process automation supporting industries: mining, metallurgy, pulp & paper, chemical, oil & gas, water treatment, cement manufacturing
Installation Requirements
- Install in any empty slot of Metso ACN CS 8/16-slot standard control rack
- Maintain 10 mm vertical ventilation gap between adjacent modules
- All external communication cables adopt fully shielded industrial Ethernet cable
- Cabinet PE grounding resistance ≤ 4 Ω to suppress communication interference
- Hot-swap allowed only when rack backplane bus is running normally
- Cabinet internal operating temperature controlled below 55 °C continuously
Operation & Maintenance Precautions
- ESD anti-static wrist strap required during module disassembly and wiring
- Conduct 6-monthly inspection of Ethernet port contact dust accumulation
- Configure redundant communication link parameters before formal system commissioning
- Avoid installation adjacent to high-power frequency converter modules
- Store spare modules in sealed anti-static packaging with desiccant
- Cut off external communication cable power before replacing damaged communication ports
