ABB CI532 3BSC140120R1 Communication Interface Module
The ABB CI532 with order code 3BSC140120R1 is a communication interface module designed for the ABB Advant Master, MOD 300, and S800 I/O system. This module serves as a critical communication gateway or fieldbus coupler, enabling the connection of ABB S800 I/O stations to higher-level control networks or to older Advant controller buses. Its primary function is to translate protocols, allowing the centralized controller to access and manage a distributed cluster of remote I/O points via a high-speed, deterministic fieldbus.
Technical Specifications
The CI532 is typically installed as the head or master module in an S800 I/O rack. It connects to the controller bus, specifically the Advant Fieldbus AF 100 which is based on PROFIBUS DP, on one side and to the S800 I/O backplane on the other. The module acts as a PROFIBUS DP slave device on the fieldbus network, with a configurable station address. The primary function is interfacing S800 I/O racks to the Advant Fieldbus AF 100, which is a PROFIBUS DP-V1 network.

Data Mapping and Configuration
The CI532 maps the I/O data from the S800 modules into the memory area of the main controller, mapping S800 I/O points to a defined block of PROFIBUS process image data that is cyclically exchanged with the PROFIBUS master. This architecture allows for distributed I/O placement close to field devices, reducing wiring costs while maintaining fast and reliable communication. The module manages the data exchange with all I/O modules in connected racks via its local bus interface. Configuration is performed using ABB engineering tools such as Advant Station or MOD 300 tools.
Legacy System Integration
The 3BSC140120R1 order code specifies a particular variant of the CI532, including its firmware and hardware configuration. This module is a key component in modernizing or extending legacy Advant and MOD 300 systems with the flexible S800 I/O technology. It allows facilities with existing Advant Master or MOD 300 controllers to incorporate modern S800 I/O modules while maintaining compatibility with the existing control infrastructure, protecting capital investment while enabling system upgrades.
Applications
The ABB CI532 3BSC140120R1 is deployed in industrial automation applications requiring distributed I/O connectivity for Advant Master and MOD 300 systems. Typical applications include process automation in chemical and petrochemical plants, power generation facilities with legacy control systems, and manufacturing plants requiring remote I/O placement. The module is also used in modernization projects where older Advant or MOD 300 systems are being upgraded with S800 I/O technology, as well as in greenfield installations where S800 I/O needs to be integrated with Advant Master controllers.
