ABB CI858K01 3BSE018135R1 | DriveBus High-Speed Communication Interface

The ABB CI858K01 is a high-performance communication interface kit designed to connect the AC 800M controller to ABB drives via the DriveBus protocol. This interface is crucial for applications requiring high-speed, deterministic coordination between the control system and variable speed drives. By utilizing a fiber optic link, the CI858K01 ensures rapid data exchange for torque, speed, and position control while providing total electrical isolation, making it ideal for the most demanding industrial drive applications.

Application Areas

The CI858K01 is primarily utilized in sectors that depend on synchronized multi-drive systems, such as metals processing (rolling mills), paper machines, and large-scale crane operations. It is the standard interface for connecting AC 800M controllers to ACS600, ACS800, ACS880, and DCS600/800 drives. Its high-speed nature makes it perfect for section-controlled machinery where precise tension and speed matching are critical to product quality.

Product Operating Instructions

The CI858K01 should be mounted on its included TP858 baseplate within an AC 800M controller rack. Ensure that the fiber optic cables (POF) are cut with the correct tool to a 90-degree angle to ensure maximum light transmission. When connecting to the drives, follow a “ring” or “star” topology as dictated by the system design, ensuring the transmitter (Tx) of the module connects to the receiver (Rx) of the drive. Configuration must be performed in ABB Control Builder M, where the DriveBus branch is defined and the individual drive addresses are mapped. Always ensure the fiber optic bend radius is not less than 25mm to avoid signal attenuation.

Common Questions & Answers

Q: How does DriveBus differ from standard Profibus or Modbus? A: DriveBus is optimized specifically for motor control, offering much faster update cycles and synchronization than general-purpose fieldbuses, which is necessary for high-performance drive coordination.

Q: Can the CI858K01 be used in a redundant AC 800M system? A: Yes, it is fully compatible with redundant CPU configurations. In such cases, the module remains on its own baseplate but communicates with the active processor.

Q: What is the maximum distance for the fiber optic link? A: Using standard plastic optical fiber, the maximum distance between nodes is typically 15 meters. For longer distances up to 200 meters, specialized HCS fiber and compatible adapters must be used.

Q: Do I need a separate power supply for the CI858 module? A: No, the module draws its internal logic power directly from the controller’s ModuleBus via the TP858 baseplate.
