ABB CI801 3BSE022366R1 – PROFIBUS DP Interface Module | AC800M Series
Engineering Background
The ABB CI801 (Part No. 3BSE022366R1) is a dedicated PROFIBUS DP communication interface module designed for integration within ABB’s AC800M Modular Controller platform — the backbone of ABB’s System 800xA Distributed Control System (DCS). Engineered for deterministic fieldbus communication in process-critical environments, the CI801 bridges the AC800M controller with PROFIBUS DP slave devices including remote I/O, drives, positioners, and intelligent field instruments.
Product Positioning
Targeted at process automation engineers and system integrators operating in oil & gas, power generation, chemical processing, and pulp & paper industries, the CI801 delivers reliable, high-speed PROFIBUS DP master functionality directly within the AC800M backplane — eliminating the need for external gateways and reducing system complexity. Konmask.com supplies this module as a genuine, tested component with full traceability documentation available upon request.

Engineering Advantages
- Native Backplane Integration: Plugs directly into the AC800M module rack — no external cabling or gateway hardware required, minimizing latency and failure points
- Full DP Master Class 1 Compliance: Supports cyclic data exchange with all standard PROFIBUS DP slaves; compatible with GSD file-based device configuration
- High Baud Rate Flexibility: Auto-negotiates from 9.6 kbps to 12 Mbps, accommodating both legacy and modern PROFIBUS networks on the same segment
- Redundancy-Ready: Supports AC800M controller redundancy configurations for SIL-rated and high-availability process applications
- Seamless 800xA Integration: Fully supported within ABB System 800xA engineering environment — device objects, faceplates, and diagnostics available natively
- Compact Form Factor: Standard AC800M module width preserves rack space in congested control cabinets
System Architecture & Signal Flow
The CI801 occupies a module slot in the AC800M controller unit (CEX bus). The AC800M CPU communicates with the CI801 via the internal module bus. The CI801 then acts as PROFIBUS DP Master on the external fieldbus segment, cyclically polling configured slave devices. Process data (I/O values, status, diagnostics) is mapped directly into the AC800M application data space and accessible to Control Builder M function blocks in real time.
Typical topology: AC800M CPU → [CEX Backplane] → CI801 → [PROFIBUS DP cable, 9-pin D-Sub] → DP Slaves (Remote I/O, Drives, Transmitters)
Termination resistors must be enabled at both physical ends of the PROFIBUS segment. Cable specification: shielded twisted pair, Type A (IEC 61158-2).

Technical FAQ
Q: Is the CI801 compatible with AC800M PM851, PM856, and PM860 CPUs?
A: Yes. The CI801 is compatible with all AC800M CPU variants that support the CEX module bus, including PM851, PM856, PM860, and PM861 processors.
Q: Can the CI801 operate as a PROFIBUS DP slave?
A: No. The CI801 functions exclusively as a Class 1 DP Master. For slave functionality within AC800M, refer to the CI840A module.
Q: How many CI801 modules can be installed per AC800M controller unit?
A: Up to 8 communication interface modules (CI-type) can be installed per AC800M controller unit, subject to backplane slot availability and CPU load constraints.
Q: What software is required to configure the CI801?
A: Configuration is performed using ABB Control Builder M (CBM) Professional or Standard edition. GSD files for connected slave devices must be imported into the CBM hardware library.
Q: Does the CI801 support PROFIBUS PA?
A: No. The CI801 supports PROFIBUS DP only. PROFIBUS PA segments require a DP/PA coupler (e.g., ABB IMFP12) connected downstream of the CI801 DP port.
Q: What is the maximum cable length per PROFIBUS segment?
A: At 12 Mbps: 100 m; at 1.5 Mbps: 200 m; at 500 kbps: 400 m; at 187.5 kbps: 1000 m; at 9.6–93.75 kbps: 1200 m. Repeaters can extend total network length.
