ABB CI851K01 Profibus DP Communication Interface Module

Description

ABB CI851K01 Profibus DP Communication Interface Module

The ABB CI851K01 is a high-performance PROFIBUS DP-V1 Communication Interface Kit designed for ABB’s System 800xA and Compact Product Suite automation platforms. It is used to connect the AC 800M controller to a decentralized network of field devices, instruments, and remote I/O.

Product Detailed Description

The CI851K01 operates as a master module on the PROFIBUS DP bus. It handles high-speed cyclical data exchange with slave devices (such as drives, motor starters, and remote I/O stations) as well as acyclical data (such as parameters and diagnostics) via the DP-V1 protocol extension.

The “K01” suffix indicates that this is a complete kit, which typically includes the CI851 communication interface module, the TP851 baseplate, and the necessary bus connectors/terminators.

Technical Parameters

Product Advantages

• High-Speed Integration: Supports the full 12 Mbps transmission rate, ensuring rapid loop updates and deterministic I/O responses for time-critical industrial loops.
• DP-V1 Capabilities: Enables intelligent device management (Asset Optimization). Maintenance teams can read complex diagnostic data and configure smart instruments remotely over the bus using FDT/DTM tools.
• Hot-Swapping: The module supports “Hot-Configuration in Run” (HCIR) and hot-swapping when paired with a redundant setup, allowing for replacements without halting production.
• System Native Compatibility: Designed exclusively for the AC 800M controller, ensuring no driver conflicts, simplified tag mapping, and seamless integration within the Control Builder M engineering software.

Important Considerations & Precautions

• Bus Termination: Ensure that the physical PROFIBUS DP network is correctly terminated with active terminators at both physical ends of the line. Improper termination is the primary cause of signal reflections and intermittent faults.
• Cable Routing: PROFIBUS lines must be separated from high-voltage AC cables and Variable Frequency Drive (VFD) output cables to minimize electromagnetic interference (EMI). Use shielded twisted-pair cables designed specifically for PROFIBUS.
• Address Configuration: No two devices on the same network can share a PROFIBUS address. Always configure unique slave addresses before commissioning the line.
• Baseplate Handling: Do not force the module into the TP851 baseplate. Ensure the alignment pins match precisely to avoid bending the connector pins.

Product Applications

The CI851K01 is used across diverse processing and manufacturing sectors to manage field networks:

• Oil & Gas / Petrochemical: Interfacing AC 800M controllers with remote valve manifolds, flowmeters, and analytical instruments located across production blocks.
• Power Plants: Connecting the main control system to distributed motor control centers (MCCs) and turbine control subsystems.
• Water & Wastewater Treatment: Linking localized pump stations and chemical dosing skids to a centralized control room.
• Pulp & Paper / Mining: Managing large arrays of variable speed drives (VFDs) and heavy machinery sensors on standard fieldbus networks.
