Product Overview

The ABB CI858K01, cataloged under order number 3BSE018135R1, serves as a specialized communication gateway within the ABB AC 800M controller ecosystem. This unit is engineered to manage the proprietary DriveBus protocol, providing the high-speed data path required to link central control logic with the high-performance drive fleet. By offloading drive communication tasks from the main processor, the CI858K01 ensures that demanding motion control loops are executed with the deterministic timing required for heavy industrial processes.

For plant engineers and automation specialists, this module acts as a critical node in motion-centric architectures. It translates abstract control signals into the precise, high-speed instructions required by ABB drives, allowing for the centralized oversight of large-scale motor fleets. With a capacity to manage up to 24 individual drive units through a single node, the module reduces physical network complexity, diminishes signal latency, and provides a centralized diagnostic stream that is essential for maintaining the operational rhythm of complex machinery.

Technical Specifications

Model Configuration Explanation

The CI858K01 configuration is a bundled solution, which includes the CI858 interface module and the TP858 baseplate. This integration is designed for streamlined deployment within existing AC 800M racks. The baseplate acts as the passive physical link to the CEX-Bus, which facilitates both data communication and power distribution. Because the module draws power directly from the CEX-Bus, system builders do not need to factor in external power distribution for this specific node, significantly simplifying the wiring cabinet layout and reducing the likelihood of power-related noise interference in the drive network.

Typical Applications

The CI858K01 is primarily utilized in environments where multi-drive coordination determines process throughput and quality:

• Paper & Pulp Manufacturing: Coordinating the complex speed-matching of rollers and drying sections to prevent paper web tension issues.

• Rolling Mills: Controlling massive electric motor lines in metallurgical facilities, where sub-millisecond synchronization of roll speeds is non-negotiable.

• Large-Scale Conveyor Systems: Managing hundreds of motors across distributed material handling lines to ensure load distribution and energy efficiency.

• Printing & Converting: Ensuring high-precision synchronization for multi-axis printing stations, where minor speed deviations lead to catastrophic alignment errors.

• Utility Pumping: Utilizing the diagnostic stream to monitor the health and torque profile of pumps in municipal water treatment arrays.

System Compatibility

The CI858K01 is specifically tuned for the ABB AC 800M controller platform. It functions as a CEX-Bus module, meaning it integrates directly into the I/O rack structure. Compatibility extends through the full 800xA and Advant OCS engineering suites. When integrated into these systems, the drive fleet managed by the CI858K01 appears as standard objects within the control software, allowing engineers to configure drive parameters, monitor alarms, and execute fault resets without ever needing to physically interface with the drive cabinet.

Installation Guidelines

• Baseplate Mounting: Secure the TP858 baseplate to the standard DIN-rail of the AC 800M subrack. Ensure the CEX-Bus connector is aligned correctly to prevent bent pins during module insertion.

• Module Insertion: The CI858 module should be slid into the baseplate until a firm mechanical connection is felt. Lock the module using the built-in locking tabs to ensure reliable electrical contact.

• Fiber Optic/Cable Routing: Route DriveBus cables in separate conduits from high-voltage power lines to maintain signal integrity. Use only approved ABB DriveBus cabling to maintain the 8 Mbit/s rated speed.

• Hot-Swap Procedure: To perform an online replacement, ensure the AC 800M processor is configured for hot-plugging. Unlock the module, withdraw it steadily, and replace it with the new unit. The bus will automatically detect the new module.

• Grounding: Ensure the TP858 baseplate is properly bonded to the cabinet’s main ground bar to establish a low-impedance path for shielding interference.

Product Advantages

• High-Speed Determinism: The 8 Mbit/s transfer rate provides the necessary bandwidth for real-time motion control, preventing the communication bottlenecking that can occur in legacy systems.

• Consolidated Architecture: By managing up to 24 drives on one module, the CI858K01 significantly reduces the controller’s hardware footprint, leaving more slots open for additional I/O or specialized interfaces.

• CEX-Bus Integration: The elimination of external power supplies for the module not only saves physical space but also reduces the number of failure points in the system.

• Predictive Diagnostics: The module feeds detailed health and performance data to the central controller, allowing for the early detection of bearing wear, over-temperature conditions, or torque anomalies before they trigger a system-wide shutdown.

Ordering Information

The CI858K01 is provided as a complete hardware kit including the module and baseplate. When preparing for site installation, ensure that the AC 800M hardware library on your engineering workstation is updated to the latest revision to support the CI858 module's features. We recommend verifying the number of drives per cabinet against the 24-drive limit per module to plan for your total hardware requirements.

Frequently Asked Questions

• Q: Can I use the CI858K01 to connect to drives from other manufacturers?

  A: No, the CI858K01 is specifically engineered for the ABB DriveBus protocol and is only compatible with ABB drives that support this communication standard.

• Q: Does the hot-swap function require a controller reset?

  A: No, the AC 800M system is designed to handle hot-swapping at the bus level without requiring a full processor reset or interruption to other I/O processes.

• Q: What happens if the CEX-Bus power is interrupted?

  A: The CI858K01 will cease communication immediately. Since the CEX-Bus also powers the processor, this would indicate a major system power failure for that subrack.

• Q: Is the 24-drive limit a hard physical constraint?

  A: Yes, the addressing and timing architecture of the module supports a maximum of 24 logical nodes. Exceeding this will result in communication errors.

• Q: How does the module handle signal noise?

  A: The module uses differential signaling and robust shielding protocols typical of the DriveBus standard, which provides high noise immunity for harsh plant floors.

• Q: Can the CI858K01 be used in a redundant controller setup?

  A: Yes, it is fully compatible with redundant AC 800M controller configurations, allowing the drive network to remain active even during a controller failover.

• Q: What maintenance is required for the module?

  A: The module is solid-state and requires no periodic maintenance other than ensuring the ventilation to the AC 800M subrack is clear and dust-free.

• Q: Where can I find the latest firmware for this module?

  A: Firmware updates are managed via the ABB 800xA system update portal or through the standard hardware library packages provided by your regional ABB support team.
