CI930F ABB AC 900F PROFIBUS DP-V1 Communication Interface

Product Overview

The ABB CI930F (3BDH001010R0002) functions as a high-performance PROFIBUS DP Master Communication Module specifically designed for the ABB AC 900F controller within the Freelance DCS ecosystem. This 100% brand new, original module establishes the critical communication link between the central controller and field-level assets, including smart sensors, actuators, motor drives, and remote I/O stations. By supporting both DP-V0 and DP-V1 standards, the CI930F enables both cyclic data exchange and acyclic parameter access. It serves as the backbone for distributed automation, ensuring synchronized control and deep diagnostics across complex process plant networks.

Technical Specifications

The CI930F utilizes dual-port memory and redundant port architecture to maximize data throughput and network uptime.

Engineering Advantages

The ABB CI930F 3BDH001010R0002 resolves fieldbus bottlenecks and reliability concerns through specialized hardware features:

• Native Line Redundancy: The CI930F features two D-Sub 9-pin connectors (A and B). This hardware configuration supports physical line redundancy, allowing the network to survive a cable break or connector failure without interrupting the process. The module switches paths instantaneously to maintain controller-to-slave connectivity.

• Dual Protocol Support (DP-V0/V1): By integrating DP-V1 capabilities, the module handles more than just simple I/O bits. It allows for the acyclic transfer of complex device parameters and diagnostic data. This enables remote calibration of field instruments and advanced troubleshooting directly from the Freelance engineering station.

• High-Speed Deterministic Exchange: The 64 kB dual-port memory architecture facilitates rapid data transfer between the PROFIBUS ASIC and the AC 900F CPU. This minimizes internal latency, ensuring that motor stop commands or safety interlocks propagate through the network with maximum speed.

• Plug-and-Play Backplane Integration: The module draws both power and logic signals directly from the AC 900F backplane. This eliminates the need for external power wiring and simplifies the physical installation, allowing for modular system expansion as plant requirements grow.

FAQs

• Does the CI930F require an external power supply?

  No. The module draws its required 80 mA current directly from the AC 900F controller backplane. You only need to provide the 24 V DC supply to the controller rack itself.

• How many PROFIBUS slaves can a single CI930F manage?

  The CI930F follows standard PROFIBUS specifications and manages up to 126 slave devices. However, ensure you use RS485 repeaters if your network segment exceeds 32 devices to maintain signal integrity.

• Is this module compatible with older Freelance software versions?

  The CI930F requires ABB Freelance Version 2013 or higher. If you are running an older version, you must upgrade your software environment to ensure the GSD files and configuration tools recognize the 3BDH001010R0002 hardware.

• Can the CI930F operate at the maximum PROFIBUS speed?

  Yes. The module supports the full PROFIBUS speed range up to 12 Mbit/s. The actual operating speed depends on the total cable length and the quality of the PROFIBUS cabling used in your installation.
