Product Functions
This high-performance communication module mainly undertakes Modbus TCP protocol data transmission and system docking tasks. It features dual RJ45 Ethernet ports to support independent network connection and redundant backup operation. The module efficiently collects real-time operating data from Modbus TCP slave devices such as sensors, inverters and on-site control units, including operational parameters, status feedback and fault information. It transmits valid field data to the AC800M main controller for logical analysis and processing, and simultaneously forwards control commands issued by the upper system to field equipment. In addition, it supports real-time network status monitoring, automatically identifies connection faults, and records communication logs to ensure continuous and orderly data interaction.
Product Features
ABB CI867K01 (3BSE043660R1) boasts outstanding communication performance and industrial environmental adaptability. It supports 10/100Mbps adaptive Ethernet transmission, delivering fast and stable data transmission with low latency. The dual-port redundant design effectively avoids network disconnection caused by single-point failure, greatly improving system operation reliability. With low power consumption and strong electromagnetic interference resistance, it can operate stably in harsh industrial environments with high temperature and strong electromagnetic radiation. The module comes with a supporting TP867 baseplate for quick and standardized installation, supports hot swapping for convenient on-site maintenance, and complies with international industrial safety standards, featuring long service life and excellent system compatibility.
