ABB CI869K01 3BSE049110R1 Ethernet Communication Interface Module

The ABB CI869K01 with order code 3BSE049110R1 is a high-performance Ethernet communication interface designed for the ABB AC 800M series of high-end Process Automation Controllers, which are a core part of the System 800xA or Compact Product Suite automation system. This module functions as a powerful and versatile network interface card, significantly expanding the controller connectivity capabilities by providing two independent, high-speed Ethernet ports for connecting to plant networks, engineering stations, operator stations, and other intelligent devices.

Technical Specifications

The CI869K01 features two independent Ethernet ports with 10/100/1000 Mbps Gigabit capability, using standard RJ45 connectors labeled X1 and X2. The module is not a simple switch but an intelligent communication module that plugs directly into the AC 800M controller rack. It supports real-time and non-real-time communication protocols, most notably MODBUS TCP/IP for both client and server operations and IEC 61850 for electrical substation automation. The K01 suffix indicates a specific hardware revision with advanced features.

Communication Protocols

The CI869K01 provides the infrastructure for ABB high-speed peer-to-peer communication over the CEX bus between multiple AC 800M controllers and their I/O systems via CI854 and CI855 modules, which is critical for building large, distributed, and synchronized control architectures. The module supports MODBUS TCP/IP client and server modes for seamless integration with a wide range of MODBUS-compatible field devices and SCADA systems. For power utility applications, the module supports IEC 61850 server and client profiles, enabling direct communication with intelligent electronic devices in electrical substations.

Network Redundancy and Performance

The CI869K01 supports hard real-time communication over the CEX bus for time-critical controller-to-controller and controller-to-I/O communication. The dual Ethernet ports can be configured for network redundancy, ensuring continued communication in the event of a cable or switch failure. Configuration is performed within the ABB Control Builder M or later Automation Builder engineering environment, involving setting IP addresses, subnet masks, gateways, and enabling specific protocols for each port. The module also supports ABB native protocols for communication with 800xA or Compact HMI and engineering stations, as well as OPC connectivity via software.

Applications

The ABB CI869K01 is essential for modern, networked control systems requiring integration with enterprise networks, SCADA systems, and intelligent field devices. Typical applications include large-scale process automation in chemical, petrochemical, and pharmaceutical industries, power generation and distribution systems requiring IEC 61850 communication, and manufacturing facilities with distributed control architectures requiring high-speed deterministic communication between multiple controllers and I/O systems.
