3BSE022366R1 CI801: CI801 integration note: PROFIBUS role, I/O supervision and configuration
CI801 (3BSE022366R1) is an S800 I/O Fieldbus Communication Interface that connects the I/O system to a controller over PROFIBUS DP-V1. ABB's hardware-selector description includes I/O ModuleBus supervision, isolated power to I/O modules, OSP handling, Hot Configuration In Run and HART pass-through. CI801 is a fieldbus interface; it is not the controller itself.

Field verification sequence
- Confirm the complete device identity and supply.
- Check terminal, bus and accessory compatibility.
- Test normal, fault and recovery behavior before handover.
Selection and compatibility checks
For 3BSE022366R1, verify the PROFIBUS DP-V1 master, GSD/device configuration, address, segment limits, I/O load, supply and environmental approvals. ABB lists CI801 as a slave interface without line or module redundancy and without hot swap. Make sure the selected design accounts for these limits rather than assuming the feature set of another CI8xx interface.
Role in the control or protection system
Use CI801 in a supported S800 I/O topology where the controller communicates with distributed I/O through PROFIBUS. Design the bus address, segment, termination and fieldbus power carefully, then coordinate the I/O configuration and OSP behavior with the controller project. HART pass-through must be enabled and supported across the complete path.
For 3BSE022366R1 CI801, establish the equipment boundary before procurement: record the host controller or panel, the connected field device, the installed hardware and firmware revisions, the supply source, the protection method and the required operating sequence. A family-name match is not enough to confirm that 3BSE022366R1 CI801 is a compatible replacement. Check all interfaces and accessories against the exact ABB documentation.
Commissioning and acceptance
After installing CI801, inspect bus termination and shield bonding, then check diagnostics at both the controller and interface. Verify every I/O module, channel status and HART communication path. Test the defined OSP response and document the bus map, module revision and configuration files.
A practical acceptance record for 3BSE022366R1 CI801 should include the nameplate photograph, order code, terminal and connector condition, configuration or setting values, software revision where applicable, test equipment and measured results. If 3BSE022366R1 CI801 is installed as part of a larger system, record the system-level response as well as the local device indication.
