ABB CI868K01 Communication Interface Module (3BSE048845R1)

The ABB CI868K01 (order code 3BSE048845R1) is a high‑performance communication interface module designed for ABB's AC 800M series controllers and System 800xA. It acts as a PROFINET IO device, allowing the ABB controller to communicate seamlessly with PROFINET IO controllers (e.g., Siemens S7‑1200/1500) and PROFINET field devices. The module supports both RT (Real‑Time) and IRT (Isochronous Real‑Time) classes of PROFINET, making it suitable for deterministic motion control and high‑speed I/O communication.

PROFINET Features

The CI868K01 supports PROFINET IO V2.3 and includes features such as device replacement (LLDP, DCP), shared device, and media redundancy (MRP client). It provides a GSDML file that describes the module's I/O data structure, which can be imported into any PROFINET engineering tool. The module also supports SNMP for network diagnostics and can be accessed via a standard web server for status monitoring.

Integration with ABB Control Systems

In an 800xA or AC 800M system, the CI868K01 is added to the hardware configuration using Control Builder M Professional. The module appears as an I/O bus device, and its process data is mapped to controller variables. Up to four CI868 modules can be installed per controller, each with its own PROFINET network. The module supports both cyclical I/O data and acyclic parameter access (records) via PROFINET.

Configuration and Commissioning

The module is configured via the Control Builder software. The user defines the slot and subslot structure (matching the GSDML). For each subslot, the I/O size is set. The module’s IP address can be assigned via DCP (Discovery and Configuration Protocol) or statically using the built‑in web interface. After downloading the configuration, the module automatically establishes communication with the PROFINET IO controller.

LED Indication and Diagnostics

Four LEDs on the front panel indicate: power (green), module status (green/red flashing for errors), link/activity (yellow/green on each RJ45 port), and PROFINET communication state (solid = data exchange, blinking = waiting). Detailed diagnostic information is available in the 800xA event list and through the web interface, which displays network statistics and error counters.

Physical and Environmental Data

The module is housed in a metal casing for better EMC shielding. It mounts on a standard DIN rail and occupies the width of a single slot (45mm). It is rated for vibration 2g (10–150Hz) and shock 15g. The module is CE, UL, and RoHS certified. It is suitable for operation in pollution degree 2 environments.

Typical Applications

The CI868K01 is used when an ABB control system needs to exchange real‑time data with a PROFINET‑based plant network, for example connecting an 800xA controller to Siemens drives, I/O blocks, or robots. It is also used for integrating ABB safety systems (AC 800M High Integrity) into a PROFINET safety network via PROFIsafe (with appropriate configuration).

Firmware and Maintenance

Firmware updates are performed via Control Builder. The module has a non‑volatile memory that retains configuration even after power loss. No battery or other user‑serviceable parts are inside. The estimated MTBF is 200,000 hours.

Conclusion

The ABB CI868K01 (3BSE048845R1) provides a reliable and high‑speed gateway between ABB controllers and PROFINET networks, enabling seamless integration into multi‑vendor automation architectures.
