ABB CI532V03 3BSE003828R1 AF 100 PROFIBUS DP Master Module
The ABB CI532V03 with order code 3BSE003828R1 is an AF 100 PROFIBUS DP master communication interface module designed for ABB Advant Master, MOD 300, and S800 I/O systems. This module serves as the primary communication head for an S800 I/O station, enabling the station to function as a remote I/O drop on the AF 100 network under the control of an Advant Master or MOD 300 series controller acting as the DP master. The V03 suffix denotes a specific hardware version of the CI532 module.
Technical Specifications
The CI532V03 is installed in the left-most slot of an S800 I/O rack. On its backplane side, it manages all data exchange with other S800 I/O modules in the same rack, including digital and analog modules. On its network side, it connects via the AF 100 interface, an RS-485 physical interface using a 9-pin D-sub female connector. The module supports PROFIBUS DP standard baud rates from 9.6 kbps up to 12 Mbps, typically auto-configured by the master. The CI532V03 acts as a DP-V1 slave on the network, cyclically exchanging process data including input and output images with the central controller.
AF 100 Fieldbus Protocol
The AF 100 fieldbus is ABB's implementation of the PROFIBUS DP-V1 standard for its Advant and MOD 300 Distributed Control Systems. The CI532V03 supports this protocol, enabling deterministic communication between the central controller and distributed I/O points. The DP-V1 standard includes both cyclic data exchange for process data and acyclic services for parameterization, diagnostics, and alarm handling. This dual capability allows the module to support not only real-time control data but also configuration and diagnostic communication for comprehensive system management.
Design and Installation
The CI532V03 is designed for reliable operation in industrial environments, featuring wide temperature tolerance and electromagnetic compatibility to withstand the interference common in factory and process automation settings. The module is installed directly into the S800 I/O rack, requiring no additional cabling for backplane communication. The front panel includes status indicators for power, communication activity, and fault conditions, facilitating on-site troubleshooting and system monitoring. The 9-pin D-sub connector provides a standardized PROFIBUS DP connection point for network cabling.

System Integration
The CI532V03 plays a crucial role in extending the I/O capabilities of an Advant or MOD 300 DCS in a distributed manner, allowing I/O points to be located close to field devices while maintaining deterministic communication with central processors. The module is compatible with the full range of S800 I/O modules, providing flexibility in configuring remote I/O stations for specific application requirements. The CI532V03 maps the I/O data from S800 modules into a predefined process image that is cyclically exchanged with the DP master, ensuring timely and reliable data transfer.
Applications
The ABB CI532V03 3BSE003828R1 is deployed in distributed control system applications requiring remote I/O communication. Typical applications include process automation in chemical plants and refineries, power generation facilities requiring distributed I/O for turbine and boiler control, and manufacturing plants with geographically distributed equipment. The module is used wherever S800 I/O stations need to be located remotely from the central controller, providing deterministic communication over the AF 100 PROFIBUS DP network while maintaining the flexibility and scalability of distributed I/O architecture.
