Overview
The ABB CI853 Communication Module is engineered to provide flexible and secure serial communication for distributed control systems. It supports both COMLI (ABB’s proprietary protocol for asynchronous master/slave communication) and MODBUS RTU, which is widely adopted across industrial devices due to its simplicity and reliability. Moreover, the CI853 allows extended cable lengths when combined with fiber optic converters, making it suitable for large‑scale installations. In addition, the module supports hot‑swap functionality, reducing downtime during maintenance and upgrades.

| Product Type | Communication Interface Module CI853 |
Typical Applications
-
Process industries: Connecting sensors, actuators, and controllers in chemical and pharmaceutical plants.
-
Power generation: Linking turbine and boiler control systems with distributed controllers.
-
Water treatment facilities: Supervising pumps, mixers, and monitoring equipment via MODBUS RTU.
-
Manufacturing automation: Integrating operator panels, drives, and interlocks with ABB AC 800M systems.
-
Infrastructure systems: Providing reliable communication for building automation and utility monitoring.
For instance, engineers often deploy the CI853 to bridge ABB controllers with third‑party devices using MODBUS RTU. Moreover, its hot‑swap capability ensures minimal downtime, while COMLI protocol provides robust communication between ABB controllers in redundant configurations.
