Working Principle The module communicates with all I/O cards on the rack backplane to collect input data and distribute output commands received from host controller. It converts backplane parallel data into network protocol packets and transmits to main controller. Received network packets are parsed and converted into backplane signals for I/O modules. Built-in diagnostic circuits monitor backplane and network communication health and report faults via LED indicators.
Installation Requirements
- Insert module into designated slot of rack with power off
- Connect network cable to module communication port
- Complete rack protective earth connection
- Keep ambient temperature 0 °C to +60 °C
- Configure network station address in controller software
- Verify data exchange between I/O rack and main controller after power on
- Lock front panel latch
Precautions
- Wear ESD protection during module handling
- Confirm network address uniqueness in control network
- Use shielded network cable and proper grounding
- Do not hot swap module without system redundancy
- Store spare module in anti-static packaging
- Check network link LED periodically
- Isolate rack power before removing module
