ABB CI867K01 (3BSE043660R1) – Modbus TCP Communication Interface Module | AC800M Platform
The ABB CI867K01, part number 3BSE043660R1, is a dedicated Modbus TCP communication interface module engineered for integration within ABB’s AC800M Distributed Control System (DCS) and PLC platform. Designed for procurement engineers and system integrators operating in process-critical environments, this module delivers deterministic Ethernet-based fieldbus connectivity with the reliability and interoperability demanded by modern industrial automation architectures.
Product Positioning: The CI867K01 serves as the primary Modbus TCP gateway within the AC800M controller rack, enabling seamless data exchange between the AC800M CPU and third-party Modbus TCP-compliant devices — including drives, meters, remote I/O, and SCADA systems — without additional protocol converters or middleware.

- Diagnostics: Full module health status visible in Control Builder M; LED indicators for link, activity, and fault states
- Scalability: Multiple CI867K01 modules can be installed per rack to expand Modbus TCP node capacity
System Architecture & Signal Flow
The CI867K01 occupies a standard module slot in the AC800M S800 I/O rack or the PM8xx CPU rack. Communication flow is as follows:
- AC800M CPU executes application task and writes/reads process data to/from CI867K01 via CEX-Bus backplane
- CI867K01 maps internal data to Modbus register tables (Coils 0x, Discrete Inputs 1x, Input Registers 3x, Holding Registers 4x)
- Modbus TCP frames are transmitted/received over the RJ-45 Ethernet port to/from field devices or SCADA
- Response data is written back to the AC800M application database within the configured scan cycle
Configuration is performed entirely within ABB Control Builder M using the CI867K01 hardware library object — no manual IP configuration via external tools required.

Technical FAQ
Q: Is CI867K01 compatible with AC800M PM891 redundant controllers?
A: Yes. The CI867K01 is fully compatible with PM891 and supports hot-standby redundancy configurations. During CPU switchover, Modbus TCP connections are re-established automatically within the configured timeout period.
Q: Can CI867K01 act as both Modbus TCP Master and Slave simultaneously?
A: No. The module operates in one role per configuration instance. However, multiple CI867K01 modules in the same rack can be configured independently — one as Master, another as Slave.
Q: What Control Builder M version is required?
A: ABB Control Builder M version 5.1 or later is recommended. The CI867K01 hardware library must be installed. Consult ABB document 3BSE043660R1 release notes for version-specific compatibility.
Q: Is the module suitable for hazardous area installation?
A: The CI867K01 itself is rated IP20 for standard control room / cabinet installation. For Zone 2 hazardous areas, it must be installed within an ATEX-certified enclosure meeting the required Ex e or Ex p protection concept.
Q: What is the maximum number of Modbus TCP nodes supported?
A: Up to 10 simultaneous TCP connections per module. For larger node counts, additional CI867K01 modules can be added to the rack.
