ABB CI868K01-eA 3BSE048845R2 Communication Module
The ABB CI868K01-eA (article number 3BSE048845R2) is a high-performance communication interface module for the AC800M series programmable logic controllers (PLC). It provides Ethernet-based connectivity with PROFINET IO (controller or device) and Modbus TCP protocols, enabling seamless integration of AC800M into industrial automation networks.
Protocols and Performance
The module supports PROFINET IO Conformance Class B (RT, Real-Time) with a cycle time down to 1 ms for 128 devices. It acts as a PROFINET controller (master) to manage up to 128 sub-devices, or as a PROFINET device (slave) for connection to higher-level controllers. Modbus TCP is supported concurrently on a separate port. The module includes two independent Ethernet ports (switchable) for line or ring topology, with link redundancy (RSTP).
Hardware Specifications
Dimensions: 119 mm x 45 mm x 102 mm. Weight: 0.2 kg. Power supply: 5 V DC from backplane (max 250 mA). The module occupies one slot in an AC800M I/O rack (S800 or S100). It features a built-in web server for diagnostics, accessible via standard browser. Status LEDs indicate power (green), link/activity (yellow), PROFINET communication (green/red), and module error (red).

Configuration and Programming
Configuration is performed in ABB Control Builder or Automation Builder. The user assigns a unique IP address via the module’s rotary switches (0-255) or via the engineering tool. A GSDML file is provided for PROFINET integration. The module supports up to 2 KB of cyclic input data and 2 KB of output data. Acyclic data (e.g., parameters) is handled via record data communication. Firmware updates are done over Ethernet using the ABB firmware manager tool.
Environmental Compliance
Operating temperature: -25°C to +70°C. Storage: -40°C to +85°C. Humidity: 5% to 95% (non-condensing). Protection: IP20. The module is certified for CE, UL, and ATEX Zone 2 (gas group IIC). It meets RoHS and WEEE standards. Vibration: 2 g (5-100 Hz) per IEC 60068-2-6.
Typical Applications
Used in process automation, manufacturing lines, and energy management systems. The CI868K01-eA allows an AC800M PLC to control PROFINET drives (e.g., ABB ACS880), I/O devices (e.g., WAGO, Siemens ET200), and communicate with SCADA via Modbus TCP. The dual-port switch enables daisy-chaining, reducing cabling costs for distributed machinery.
