Product Introduction
A distributed I/O station is only as dependable as its communication interface. If the fieldbus connection fails, the controller can lose access to an entire group of process signals even when individual I/O modules remain operational.
The ABB CI801 is the PROFIBUS DP-V1 Fieldbus Communication Interface for the S800 I/O system. It connects the local I/O station to a supervisory controller while managing ModuleBus communication, I/O module supervision, and configuration functions. Additional capabilities include Output Set as Predetermined (OSP), Hot Configuration In Run (HCIR), and HART pass-through. For plants maintaining established S800 installations, the CI801 remains an important communication spare.

Field Applications & Technical Pitfalls
Typical Applications
1. Distributed Process I/O Stations
The CI801 provides the communication link between S800 I/O modules and the parent control system. It is used in distributed architectures where field signals are collected locally and transferred to a central controller over PROFIBUS DP-V1.
2. System 800xA Process Automation
Within ABB System 800xA installations, the CI801 supports communication between the S800 I/O station and the controller. It handles local I/O supervision and configuration-related functions, reducing the need for a separate communication interface for each individual I/O module.
3. Smart Instrument Integration
HART pass-through allows compatible smart field instruments to exchange additional device information through the analog I/O communication path. This can support instrument configuration and maintenance without relying solely on the 4–20 mA process signal.
Three Replacement Checks Engineers Should Not Skip
1. Verify the PROFIBUS configuration.
The operates as a PROFIBUS DP-V1 slave. Check the network address, GSD configuration, bus parameters, connector wiring, and controller-side configuration before replacing the module. A replacement with a different fieldbus interface cannot be treated as a direct substitute.
2. Check the supported S800 I/O module list.
The basic system software loaded in the does not support every I/O module. ABB documentation identifies DI825, DI830, DI831, DI885, AI880, DI880, and DO880 among the unsupported modules for the referenced software configuration. Verify the installed I/O lineup and software compatibility before ordering.
3. Review the redundancy and replacement procedure.
The does not support line redundancy, module redundancy, or hot swapping. Do not assume that it can be replaced online without affecting the I/O station. Review the system architecture and approved shutdown or maintenance procedure first.
Field note: A may show normal power status while the controller still cannot communicate with the I/O station. In this situation, check PROFIBUS addressing, bus termination, connector wiring, and the local ModuleBus configuration before concluding that the replacement module is defective.
Important: The is not equivalent to the CI840A or CI845. Those models have different communication and redundancy characteristics. Compare the complete article number and system architecture before considering any alternative.
Quality Control (QC) SOP & Transparency
Our inspection process for the ABB focuses on part-number accuracy, communication interfaces, and physical condition.
- Part Number Verification: Confirm the designation and 3BSE022366R1 article number against the customer’s requirement.
- Visual Inspection: Examine the housing, PCB, connectors, terminals, and front-panel indicators for damage, corrosion, or signs of improper handling.
- Accessory Check: Verify the power supply connector and TB807 ModuleBus terminator where included in the supplied package.
- Functional Testing: Where a compatible I/O rack and PROFIBUS test setup are available, check startup, communication status, and ModuleBus operation.
- Configuration Review: Confirm that the intended I/O modules are supported by the installed software configuration.
- Final QA and Packaging: Record inspection findings and protect the communication connectors and module housing for export shipment.
Live video inspection can be arranged after the goods arrive at our headquarters. A 12-month warranty is available, subject to order confirmation and the agreed product condition.
Frequently Asked Questions (FAQ)
Q1: What is the ABB 3BSE022366R1 used for?
It is a PROFIBUS DP-V1 Fieldbus Communication Interface for ABB I/O. It connects an I/O station to a parent controller and manages local I/O communication and supervision.
Q2: Is the a PROFIBUS master or slave?
It operates as a PROFIBUS DP-V1 slave. The parent controller communicates with the over the fieldbus.
Q3: Does the support HART communication?
Yes. It supports HART pass-through, allowing compatible HART field devices to exchange additional information through the relevant analog I/O arrangement.
Q4: How many I/O modules can one support?
ABB specifies up to 12 I/O modules on the electrical ModuleBus. Up to seven I/O clusters can be connected through TB842 optical ModuleBus arrangements, subject to the system configuration.
Q5: Can the be hot-swapped?
No. ABB’s product specifications identify hot swap as unsupported. Follow the plant’s approved maintenance procedure before removing or replacing the module.
Q6: Is the compatible with CI840A or CI845?
They belong to the I/O communication interface family but use different communication architectures and have different redundancy features. They should not be considered direct replacements without a system-level compatibility review.
Q7: What warranty and inspection support do you provide?
We offer a 12-month warranty, subject to order confirmation and product condition. Part-number verification, visual inspection, and applicable functional testing can be arranged. Live video inspection is also available after the goods arrive at our headquarters.
