ABB CI522AK04 3BSE018451R1 PROFIBUS DP Communication Module
The ABB CI522AK04 with part number 3BSE018451R1 is a high-speed PROFIBUS DP communication module from the AC 800M series, designed to enable seamless data exchange between industrial controllers and PROFIBUS DP field devices. The module supports both master and slave modes for flexible automation integration, allowing it to function as either a DP master controlling multiple slave devices or as a DP slave connected to a higher-level master controller.
Technical Specifications
The CI522AK04 3BSE018451R1 supports PROFIBUS DP communication speeds from 9.6 kbps up to 12 Mbps with auto-negotiation capability. The bus topology supports line and star configurations with repeaters, accommodating up to 127 nodes per bus segment. Maximum cable length varies with baud rate, extending to 1000 meters at 9.6 kbps and 100 meters at 12 Mbps using standard PROFIBUS DP cable. The module features bus isolation rated at 500V AC for one minute, providing protection against electrical interference and ground loops. Power supply is 24V DC ±10% with a typical power consumption of 2.5 watts and maximum of 3.5 watts.

Master and Slave Modes
The CI522AK04 supports both master and slave modes of operation. In master mode, the module acts as a PROFIBUS DP master, controlling communication with multiple slave devices, managing cyclic data exchange, and handling parameter assignment and diagnostics. In slave mode, the module allows the AC 800M controller to act as a DP slave on a PROFIBUS network, enabling integration into larger automation architectures where another controller serves as the network master. This dual-mode capability provides flexibility for various system integration scenarios, from small standalone applications to large distributed control networks.
Core Functions and Features
Core functions of the CI522AK04 include high-speed data transmission for real-time control, bus fault detection for network reliability, and device status monitoring for field device health. The module supports bus fault detection to identify communication issues and maintain system integrity. Device status monitoring allows the controller to receive diagnostic information from connected PROFIBUS DP field devices, including sensors, drives, and valves, enabling predictive maintenance and rapid fault diagnosis. The module is compatible with ABB AC 800M controllers and PROFIBUS DP field devices, and is configured using Compact Control Builder software.
