ABB CI857 Communication Interface Module

The ABB CI857 Communication Interface Module is a high-performance communication interface module in the AC 800M controller series. Here is a detailed introduction to it:
I. Basic Information
Product Number: 3BSE018144R1
Brand/Manufacturer: ABB Company
Series: AC 800M Controller Series
Type: Communication Interface Module

Main features
High-performance communication:
The CI857 module supports high-speed data transmission, with a transmission speed of up to 10 Mbit/s, which can meet the requirements of real-time and high-speed communication in industrial automation systems.
It realizes some functions of the physical layer and data link layer of the Ethernet protocol, such as address resolution, data framing, and flow control, ensuring the stability and reliability of data transmission.
Support for multiple communication protocols:
The CI857 module supports ABB’s INSUM communication protocol, which is a system used for motor and switch device control and protection. Through TCP/IP gateway and CI857 interface module, PLC can be integrated with the INSUM system to achieve data exchange and function sharing.
In addition, the CI857 module also supports Profibus DP-V1 master/slave protocol, which complies with EN 50170 standards, with a data transmission rate of up to 12 Mbps, and can connect up to 125 slave devices.
Modular design:
The CI857 module adopts a modular design, making it convenient for users to expand and configure according to actual needs. It supports hot-swappable function, allowing module replacement and upgrade without interrupting the system operation.
The front panel of the module is equipped with indicator lights, facilitating users to monitor the operation status of the module. At the same time, it provides an RJ-45 female interface (8 pins), facilitating connection with network devices such as Ethernet.
High reliability and stability:
The CI857 module is designed for industrial environments and has high reliability and stability. It can operate normally under harsh working conditions, ensuring the continuity and stability of industrial automation systems.
The module supports redundant configuration (although some materials indicate that the CI857 itself does not support line redundancy and module redundancy, the AC 800M series controller as a whole supports redundant technology, and users can achieve system redundancy through other methods), improving the system’s availability and reliability.
Easy configuration and management:
The CI857 module provides configuration and management tools, facilitating users to set and monitor the module. Users can configure and manage the communication parameters, network settings, etc. of the module through these tools, simplifying the system maintenance and management process.

Application scenario
Industrial Automation System: The CI857 module is widely used in industrial automation systems to facilitate high-speed data exchange between controllers and various on-site devices. It can connect sensors, actuators, intelligent instruments, and other equipment to achieve real-time monitoring and control of industrial processes.
Motor and Switch Equipment Control and Protection: By supporting the INSUM communication protocol, the CI857 module can be integrated with ABB’s motor and switch equipment control and protection system, enabling higher-level functional integration and configuration flexibility.
Multi-brand Equipment Integration: The CI857 module supports multiple communication protocols and interfaces, allowing it to connect different brands and types of devices, enabling seamless communication and data exchange between devices. This helps users build more open and flexible industrial automation systems.
