The ABB CI867AK01 (3BSE092689R1) is a high-performance Modbus TCP communication interface module designed for the ABB AC 800M control system family. This kit includes the CI867 communication module and the required TP867 mounting base for seamless integration into the controller rack.

Features

• Dual RJ45 Ethernet ports supporting 10/100 Mbps data rates.
• Configurable as both Modbus TCP client (master) and server (slave).
• Supports cyclic and acyclic data exchange for process variables.
• Compatible with standard Modbus data types including coils, discrete inputs, and registers.
• Supports 16-bit and 32-bit register access with configurable byte/word swapping.
• Hot-swap capability allows for module replacement without requiring a system shutdown.
• Integrates directly into the Control Builder M or Compact Control Builder engineering environment.

Applications

• Oil and Gas: Integration of remote I/O and field devices on offshore platforms and refineries.
• Power and Utilities: Data exchange with power meters and protection relays in water treatment and power plants.
• Chemical and Petrochemical: Reliable communication bridge for third-party PLCs and variable frequency drives.
• Manufacturing: Scalable connectivity for automated batch processing and high-availability systems.

Technical Specifications

Installation Guidelines

• Mount the TP867 baseplate onto a standard 35 mm top-hat DIN rail.
• Slide the baseplate along the rail to engage the CEX-Bus side connector with the controller or adjacent module.
• Align the CI867 module with the TP867 base and press firmly until the locking mechanism clicks.
• Ensure proper grounding of the DIN rail to maintain EMI immunity.
• Always power down the system before installing or removing modules if hot-swap procedures are not explicitly active in your specific configuration.

FAQ

What is the primary function of the CI867AK01?

The CI867AK01 acts as a communication bridge, allowing the ABB AC 800M controller to exchange process data with third-party Modbus TCP-compatible devices such as VFDs, motor starters, and remote I/O stations.

Does this module support redundancy?

Yes, the CI867 supports redundant configurations, allowing for high-availability communication in critical industrial applications.

Can this module be used as a master and a slave?

Yes, the module is highly flexible and can be configured to act as a Modbus TCP client (master) to poll field devices or as a server (slave) to provide data to upper-level SCADA or DCS systems.
