ABB CI801 (3BSE022366R1) – Fieldbus Communication Interface Module | AC800M Controller Platform
Engineering Background
The ABB CI801 is a dedicated fieldbus communication interface module engineered for the AC800M Modular Controller platform — ABB’s flagship DCS/PLC solution widely deployed in power generation, oil & gas, pulp & paper, and chemical processing industries. The CI801 enables seamless integration between the AC800M controller and PROFIBUS DP field devices, providing deterministic, high-speed process data exchange in demanding industrial environments.
Product Positioning
Designed for system integrators and process automation engineers who require a proven, OEM-sourced communication interface with full compatibility across the AC800M ecosystem. The CI801 (part number 3BSE022366R1) is a direct ABB factory component — not a third-party substitute — ensuring full firmware compatibility, diagnostic transparency, and long-term supportability within existing ABB 800xA and Symphony Plus architectures.

- Redundancy Support: Compatible with AC800M redundant controller configurations for high-availability architectures
- Diagnostic Transparency: Slave diagnostics accessible directly through ABB 800xA or Symphony Plus HMI layers
- Scalable Topology: Supports star, line, and tree PROFIBUS segment topologies with repeaters
- Long-Term Availability: ABB AC800M platform with extended lifecycle support — CI801 remains an active catalog item
System Architecture & Signal Flow
The CI801 mounts directly onto the AC800M controller module rack. The AC800M CPU communicates with the CI801 via the internal S800 I/O bus, which the CI801 translates into PROFIBUS DP protocol frames on the external DB9 fieldbus segment. Process data (inputs/outputs) is mapped cyclically between PROFIBUS DP slave devices and the AC800M application program variables. Configuration and parameterization are performed offline in ABB Control Builder M and downloaded to the controller — the CI801 requires no standalone configuration tool.
Signal Flow: AC800M CPU Application ↔ S800 Backplane Bus ↔ CI801 ↔ PROFIBUS DP Segment ↔ Field Devices (transmitters, drives, positioners, remote I/O)

Technical FAQ
Q: Is the CI801 compatible with AC800M firmware versions above 5.x?
A: The CI801 hardware is compatible across AC800M firmware generations. Verify the specific firmware compatibility matrix in ABB document 3BSE036351 (AC800M Hardware Unit Description) for your controller revision.
Q: Can the CI801 operate as a PROFIBUS DP slave?
A: No. The CI801 is a DP Master Class 1 module only. For slave functionality, refer to ABB CI840A or CI854A modules.
Q: What is the maximum cable length per PROFIBUS DP segment?
A: At 1.5 Mbps, maximum segment length is 200 m. At 93.75 kbps, up to 1200 m. Use repeaters to extend beyond single-segment limits.
Q: Does the CI801 support PROFIBUS PA?
A: No. CI801 is PROFIBUS DP only. PROFIBUS PA requires a DP/PA coupler or link device in the segment.
Q: Is a warranty provided?
A: Konmask provides a 90-day functional warranty on all verified surplus units. Extended warranty options available — contact us for details.
