ABB CI867AK01 3BSE0929689R1 Modbus TCP Interface

ABB CI867AK01 3BSE0929689R1 is a Modbus TCP interface module used to connect AC 800M controllers with external Ethernet devices in industrial automation systems. It uses the Modbus TCP protocol to combine the simplicity of Modbus RTU with Ethernet TCP/IP to provide data exchange. The following is a detailed overview of its main functions, features and applications:

Fuctions & Features

• Support Modbus TCP protocol: Based on the request-response mechanism, the ABB CI867AK01 module provides different services through function codes, connecting the traditional Modbus RTU protocol with Ethernet and TCP/IP networks.

• Equipped with Ethernet interface: It is a single-channel Ethernet interface. The ABB CI867AK01 module supports full-duplex 100Mbps data transmission rate and can be connected to the main network through an Ethernet switch.

• Support master-slave function: The ABB CI867AK01 module supports the master-slave function of Modbus TCP and can work as a master or slave device. Each CI867A module supports up to 70 slave devices and 8 master devices.

• Working mechanism: The ABB CI867AK01 module is configured with redundant working mode. There will be two or more CI867AK01 modules running simultaneously in the system, and they will monitor and back up each other. Under normal circumstances, the main module is responsible for data communication and processing, and the standby module is in hot standby state, synchronizing the data and status of the main module in real time.

Specification

Application
