ABB CI858K01 3BSE018135R1 – DriveBus Communication Interface Module

Product Overview

The ABB CI858K01 3BSE018135R1 is a DriveBus communication interface module specially designed for ABB’s AC 800M and System 800xA automation platforms. It acts as a high‑performance communication bridge between the control system and multiple ABB drives or special I/O units, delivering reliable data exchange and coordinated control in complex industrial applications.

Key Features

• DriveBus Protocol Support: Implements the ABB proprietary DriveBus protocol for real‑time communication with drives and devices.
• High Connectivity: Supports connection of up to 24 ABB drives per module, enabling large‑scale distributed control.
• Hot‑Swappable Design: Allows module replacement or service without halting the control system, improving uptime.
• CEX‑Bus Powered: Powered directly from the controller’s CEX‑Bus, eliminating the need for an external power supply.
• Compact & Lightweight: Designed for efficient installation in control cabinets or DIN‑rail applications.
• IP20 Protection: Suitable for industrial control environments.

Structure & Functional Design

The CI858K01 consists of two primary components:

• CI858 Communication Interface: The core communication unit handling DriveBus protocol exchange.
• TP858 Baseplate: Provides mechanical support and connection interface for field wiring and system backplane.

The baseplate includes connectors for DriveBus field cabling, while the interface unit contains logic and communication circuitry to interface with both drives and the AC 800M/CEX‑Bus backplane.

Applications & Integration

This module is widely used in industrial automation systems requiring synchronized multi‑drive operation and flexible communications:

• Rolling mills and paper machine drive systems – for coordinated motion control.
• Process automation systems incorporating multiple VFDs and special I/O.
• Machine lines and material handling systems requiring real‑time control and high data throughput.
• Large manufacturing lines where DriveBus helps centralize communication and control.

Installation & Commissioning

• Mounting: Attach the module with its baseplate in the control cabinet or rack unit designated for DriveBus modules.
• Cabling: Connect DriveBus field wiring to the baseplate connectors; integrate with controller backplane via CEX‑Bus.
• Hot Swap Capability: Replace or service the module while the system is operating, supported by DriveBus redundancy design.
• Configuration: Parameterize DriveBus node settings such as addresses and speeds per system documentation.

Maintenance & Troubleshooting

• Periodic Inspection: Check connectors for wear, dust, or corrosion.
• Firmware Checks: Ensure module firmware aligns with controller and drive versions.
• Network Diagnostics: Monitor DriveBus traffic and signal integrity during commissioning and operation.

Benefits & Use Case Highlights

• Improves system scalability by supporting multiple drives on a single communication backbone.
• Enhances maintenance efficiency via hot‑swap capability.
• Reduces wiring complexity and improves synchronization in distributed control architectures.
