Product Introduction
The ABB CI858K01 3BSE018135R1 is a DriveBus communication interface for AC 800M controllers. Its job is to provide the communication path between the controller and compatible ABB drives or ABB Special I/O units using ABB’s DriveBus protocol. The K01 package contains the CI858 communication interface together with its TP858 baseplate.
DriveBus was developed for applications where the controller needs direct communication with ABB drive systems, particularly sectional-drive installations such as rolling mills and paper machines. One CI858 can handle up to 24 ABB drives, while an AC 800M controller can accommodate up to two CI858 interfaces.

Application Scenarios & Field Pitfalls — Engineer’s Perspective
Engineering Pain Point
A failure can look like a drive problem even when the actual fault is in the controller-side communication path. Drive status, commands, diagnostics, and configuration depend on the correct DriveBus interface and physical optical connection.
Typical Applications
- ABB AC 800M controller systems requiring DriveBus communication
- Rolling mill sectional-drive systems
- Paper-machine drive control
- ABB drive networks using optical DriveBus connections
- AC 800M systems communicating with ABB Special I/O units
Technical Pitfalls to Avoid
- Do not treat as a generic Ethernet or fieldbus module.
It is specifically a DriveBus interface. The communication protocol is ABB DriveBus, not standard Ethernet, Modbus TCP, or PROFIBUS. - Check the complete K01 package.
ABB defines CI858K01 / 3BSE018135R1 as a package containing the module and TP858 baseplate. Buying a module alone is not equivalent to receiving the complete K01 package. - Verify the optical network arrangement.
ABB specifies an optical connector for the . Fiber type, optical components, DriveBus topology, and connected drive hardware should be checked against the existing installation before commissioning. - Do not assume redundancy.
ABB explicitly lists both line redundancy and module redundancy as unavailable for . Two units can be installed on an AC 800M controller, but that should not be interpreted as automatic communication redundancy. - Check the CEX-Bus configuration.
The receives its operating power through the processor unit via the CEX-Bus and does not require a separate external power source. CEX-Bus capacity and termination should therefore be checked when adding or replacing the interface.

Procurement Check
For an ABB 3BSE018135R1, verify these items before approving a replacement:
- Exact designation:
- Product ID: 3BSE018135R1
- communication module included
- TP858 baseplate included
- Existing AC 800M processor and CEX-Bus architecture
- DriveBus optical connection
- Connected ABB drive models
- Number of DriveBus-connected drives
- Existing NDBU branching arrangement, if multiple drives are connected
- Controller configuration and application software
- Communication-interface firmware

Recommended procurement description:
ABB 3BSE018135R1 DriveBus Interface Package, AC 800M Communication Module, ABB DriveBus Master, 8 Mbit/s Optical Interface, Includes and TP858 Baseplate.
The important distinction is simple: is a controller-to-drive communication interface, not a drive itself and not a general-purpose I/O card. For field replacement, matching the DriveBus architecture and package is more important than matching the physical dimensions alone.
