ABB TP867 Communication Interface Baseplate

ABB TP867 is a passive communication baseplate developed for ABB AC 800M controller under System 800xA DCS platform. It serves as the carrier and signal interface for CI867, CI868 and other communication modules, providing dual RJ45 Ethernet ports and CEX bus backplane connection.

This baseplate comes with CH1 10/100Mbps and CH2 10Mbps Ethernet interfaces, supporting galvanic isolation and hot swap of the upper communication module. It adopts DIN rail mounting, widely used as spare parts for process control DCS cabinet upgrade and maintenance in chemical, power and pulp & paper industries.

FAQ

1. Q: Can TP867 work alone without CI867 module?
   A: TP867 is passive baseplate only, it must work with matching communication module like CI867 to realize network communication.
2. Q: What are typical baseplate failure symptoms?
   A: Ethernet port no link, CEX bus communication interruption, upper communication module cannot be recognized.
3. Q: How to complete commissioning and diagnosis?
   A: Mount TP867 on DIN rail, install CI communication module, connect Ethernet cable and verify CEX bus and network link status.
