Product Overview
Integrating motor control and switchgear monitoring into your AC 800M controller has never been more efficient. The ABB CI857 Industrial Automation Module bridges the gap between INSUM devices and the AC 800M, enabling higher functionality integration, multidrop configurations, and precise time distribution and time stamping directly in the switchgear. This module leverages standard Ethernet technology to achieve longer communication distances, making it an ideal choice for distributed industrial environments.
The ABB CI857 is powered directly by the processor unit via the CEX-Bus, eliminating the need for an additional external power source. This simplifies installation and reduces wiring complexity, allowing you to focus on your core operations.
Key Features & Benefits
-
High Capacity: Supports up to 256 MCUs (or other INSUM devices) per AC 800M with PM864 or PM866, and up to 128 with PM861.
-
Scalable Architecture: Up to 6 CI857 modules can be installed per AC 800M, each handling up to 128 INSUM devices.
-
Efficient Communication: Each CI857 supports up to 2 INSUM TCP/IP Gateways, with each gateway managing up to 128 INSUM devices across 4 LonWorks subnets (max 32 devices per subnet).
-
Fast Loop Speed: Typical closed-loop response time is 500 ms (indication from one motor to operation of another, assuming a 250 ms control cycle).
-
Hot Swap Capability: Replace or add modules without shutting down the system, minimizing downtime.

Real-World Applications
The ABB CI857 excels in industries where reliable motor control and switchgear monitoring are critical. In a typical manufacturing plant, this module enables seamless coordination between multiple motors, reducing response time and improving operational safety. For example, in a conveyor system, the CI857 can quickly signal a downstream motor to stop when an upstream motor faults, preventing product damage and minimizing downtime.
In power generation facilities, the CI857 supports time stamping and time distribution, ensuring accurate event logging for troubleshooting and compliance. Its multidrop configuration capability allows you to connect multiple INSUM devices over long distances using Ethernet, reducing cabling costs and simplifying system architecture.
Installation & Setup Guidance
Installing the ABB CI857 is straightforward. The module mounts onto the CEX-Bus backplane of the AC 800M controller. No additional power supply is needed, as the module draws power from the processor unit. Connect the RJ-45 female connector to your INSUM TCP/IP Gateway using standard Ethernet cables. Ensure the module is properly seated and secured to guarantee reliable communication. For optimal performance, verify that the firmware of the AC 800M supports the CI857 and configure the communication parameters in the INSUM Communication Library.
Maintenance & Reliability
Routine maintenance for the CI857 is minimal. Periodically inspect the Ethernet connections for secure fit and check for any signs of corrosion, especially in harsh environments. The module's IP20 protection class requires installation in a clean, dry enclosure. Operating within the specified temperature range (0 to +55 °C) ensures long-term reliability. The hot-swap feature allows you to replace a faulty module without stopping the entire system, reducing downtime and maintenance costs.
Compatibility & Integration
The ABB CI857 is specifically designed for use with ABB's AC 800M controllers. It communicates using the INSUM protocol, making it compatible with INSUM devices and gateways. With support for up to 6 CI857 modules per AC 800M, you can build a highly scalable motor control network. The module integrates seamlessly with the INSUM Communication Library, providing function blocks for easy programming.
Selection Guide & Purchasing Advice
Before purchasing the ABB CI857, verify your AC 800M controller model (PM861, PM864, or PM866) to ensure compatibility. Confirm the number of INSUM devices you need to connect and the required communication distance. If you need to expand beyond 128 devices per CI857, consider adding more modules.
