4. Product Introduction (Anti-Template)
The ABB CI858K01 (ordering code 3BSE018135R1) is a DriveBus communication interface module for the AC 800M controller in System 800xA. It enables high-speed optical communication between the controller and ABB drives (and certain special I/O units) using the DriveBus protocol.
The supplied package includes the CI858 communication interface and the TP858 baseplate. Up to 24 ABB drives can be connected to one CI858; a maximum of two CI858 modules can be mounted on a single AC 800M controller via the CEX-Bus. When multiple drives are connected, a branching unit (NDBU) is required to create a logical bus in a physical star topology. The module supports hot-swap and draws its power directly from the CEX-Bus, so no external power supply is needed. DriveBus is particularly suited to sectional drive applications such as paper machines and rolling mills.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Confirm full designation (CI858K01 / 3BSE018135R1), presence of both the CI858 module and TP858 baseplate, and condition of the optical connector. Photograph all labels.
- Functional Testing – Install on a compatible AC 800M CEX-Bus, verify power-up and basic communication readiness where test equipment is available.
- QA & Packaging – Protect the optical port and baseplate connectors, clean the unit, and pack in anti-static protective packaging.
- Global Logistics & Export Compliance – Classify under the correct HS code for industrial communication modules. Packaging must protect the optical interface; export documentation is prepared to minimize customs delays.
6. Technical Pitfalls & Integration Warnings
Optical Fiber Handling – Use only approved optical cables and maintain clean connectors. Contaminated or damaged fibers are a common cause of communication failure.
Branching Unit Requirement – When connecting more than one drive, an NDBU branching unit is mandatory. Incorrect topology prevents proper DriveBus operation.
CEX-Bus Limits – A maximum of two CI858 modules is supported per AC 800M controller. Exceeding this limit is not allowed.
Hot-Swap Procedure – Although hot-swap is supported, follow ABB guidelines to avoid disruption of existing DriveBus traffic during replacement.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified CI858K01 3BSE018135R1?
As a specialized AC 800M communication module, availability depends on surplus stock. Typical lead time after verification is 5–15 business days plus standard shipping.
What is the function of the CI858K01?
It is the DriveBus interface that connects ABB drives to an AC 800M controller via optical communication.
What does the package include?
The communication interface module and the TP858 baseplate.
How many drives can be connected?
Up to 24 drives per module (branching unit required for more than one drive).
Does it need an external power supply?
No. It is powered from the AC 800M CEX-Bus.
Is the module still in production?
Yes. The DriveBus interface remains part of the active AC 800M communication module portfolio for System 800xA.
What should be confirmed before ordering a replacement?
Exact ordering code (3BSE018135R1), presence of the TP858 baseplate, number of drives to be connected, and compatibility with the existing AC 800M controller and DriveBus network.
