Maintenance
- Routine inspection: Check module LED status, CEX bus connector and Ethernet cable connection every 6–12 months
- Clean module surface with dry compressed air; liquid solvent cleaning is strictly prohibited
- ESD protection must be adopted during disassembly, anti-static wristband required
- If Modbus communication timeout or link loss occurs, check Ethernet wiring, IP address configuration and slave device status
- Do not energize the module if PCB corrosion, burn marks or condensation are found
- We support function testing, refurbishment and spare replacement service for this CI867K01 communication kit
Installation
- Hot-swap replacement can be performed following system safety procedure or cut off cabinet power supply.
- Wear anti-static wristband to prevent electrostatic damage to PCB and communication chips.
- Install TP867 baseplate into rack slot, insert CI867 module and lock fastening latch.
- Connect shielded Ethernet cables to RJ45 ports, properly ground cable shielding.
- Configure Modbus TCP mode, IP address, slave station and data mapping parameters via Compact Control Builder.
- Check all wiring and confirm no loose connections.
- Restore power supply, verify CEX bus communication.
- Test data read/write with Modbus TCP field devices, confirm stable data exchange and complete commissioning.
