ABB CI867K01 3BSE043660R1 Retrofit PROFINET IO Module

ABB CI867K01 3BSE043660R1 Retrofit PROFINET IO Module: Legacy System Compatibility & Smooth Upgrade

The ABB CI867K01 (Part No. 3BSE043660R1) is a PROFINET IO communication interface module designed for the ABB AC800M controller platform. As industrial facilities worldwide face the challenge of maintaining aging distributed control systems (DCS) and programmable logic controller (PLC) networks, the CI867K01 has become a critical component in retrofit projects, discontinued spare part replacement programs, and control cabinet modernization initiatives. NINERMAS maintains verified stock of this module with full functional testing and a 12-month warranty, supporting customers who need to extend the operational life of their existing automation infrastructure without committing to a full system overhaul.

The CI867K01 slots directly into the AC800M processor unit — typically alongside the PM861A, PM864A, or PM866A controller modules — and provides a dedicated PROFINET IO controller interface. This allows the AC800M to communicate with field devices, remote I/O stations, and distributed peripherals over a standard PROFINET network. In legacy installations where the original CI867 (without the K01 revision) or earlier communication modules such as the CI854A (PROFIBUS DP) or CI855 were used, the CI867K01 represents a direct upgrade path that preserves the existing rack and backplane infrastructure while enabling migration to PROFINET-based field devices.

Retrofit Planning for Existing Automation Systems

Successful integration of the CI867K01 into a legacy AC800M system begins well before the module arrives on site. Engineers responsible for the retrofit must first audit the existing rack configuration to confirm that a compatible module slot is available. In many older AC800M installations, the rack may already be populated with a CI854A PROFIBUS DP module, a CI855 AF100 interface, or an earlier revision CI867. If the replacement is a like-for-like CI867K01 swap, the physical installation is straightforward — the module slides into the same slot position and the backplane connection is maintained. However, if the project involves migrating from PROFIBUS DP to PROFINET, the engineering scope expands significantly.

Before removing the existing communication module, the project team should export a full backup of the AC800M application using Control Builder M Professional. This backup preserves all function block logic, I/O signal assignments, and communication object configurations. The PROFINET device list must then be rebuilt within the project, with each field device — including remote I/O stations such as the S800 I/O modules (AI810, AO810V2, DI810, DO810) connected via CI820V1 or CI830 fieldbus modules — re-declared as a PROFINET IO device using its GSDML file. Signal mapping between the controller application and the new PROFINET device addresses must be verified against the original PROFIBUS DP signal list to ensure no I/O points are lost during migration.

Power supply capacity is a frequently overlooked aspect of retrofit planning. The SD802F or SD803F power supply modules feeding the AC800M rack must be confirmed to have sufficient headroom to support the CI867K01 alongside existing modules. If the rack is already near capacity, a supplementary power supply or load redistribution across multiple racks may be required. Similarly, the TB820V2 termination board and associated field wiring must be inspected to confirm that terminal assignments remain compatible with the new module’s I/O channel mapping.

For installations where the AC800M communicates upstream to an ABB 800xA Distributed Control System, the addition of the CI867K01 may require updates to the 800xA system topology configuration, OPC server settings, and operator station HMI graphics. Faceplates linked to PROFIBUS DP device objects will need to be remapped to their PROFINET equivalents. In parallel, any AF100 or Modulebus segments that previously bridged the AC800M to legacy S100 or S200 I/O panels should be reviewed for compatibility with the new communication architecture. If signal isolators or MTL or P+F barriers are present in the field wiring, their terminal assignments and loop power configurations must be verified against the new I/O module channel specifications.

Downtime Control During System Migration

Minimizing production downtime during a CI867K01 retrofit requires a structured migration plan that separates preparation work from the actual cutover window. The majority of engineering effort — including project backup, PROFINET device configuration, GSDML import, signal remapping, and offline simulation — should be completed before any live system work begins. Where the control system architecture permits, a parallel commissioning approach can be used: the new CI867K01 and its associated PROFINET field devices are configured and tested on a bench or in a staging rack before the cutover, allowing engineers to validate communication links, I/O response, and controller logic without interrupting production.

During the cutover window itself, the sequence should follow a defined procedure: isolate the affected control loop or production segment, export a final application backup, remove the legacy communication module, install the CI867K01, restore power, download the updated application, and verify all I/O signals against the pre-migration signal list. The use of a programming cable (such as the TK212A USB-to-serial adapter) connected directly to the AC800M processor’s local port allows engineers to monitor controller status and download application updates without relying on the network infrastructure that is being reconfigured. Once the CI867K01 is online and all PROFINET devices are communicating, a full I/O scan and loop check should be performed before returning the system to automatic control.

For critical processes where even a brief interruption is unacceptable, a hot-standby or redundant controller configuration using paired PM864A or PM866A processors with redundant CI867K01 modules can be considered. In this architecture, the standby controller maintains a synchronized copy of the application state, allowing seamless bumpless transfer if the primary module is replaced. NINERMAS can supply matched pairs of CI867K01 modules with verified firmware revision alignment to support redundant configurations.

All CI867K01 modules supplied by NINERMAS undergo a pre-shipment functional test that verifies PROFINET communication initialization, backplane interface integrity, and firmware version. A test report is included with each shipment. The 12-month warranty covers manufacturing defects and functional failures under normal operating conditions, providing customers with confidence that the replacement module will perform reliably from the moment it is installed.

Retrofit Support FAQ

Q1: Can the CI867K01 3BSE043660R1 directly replace an older CI867 module without any software changes?
A: In most cases, yes — if the existing project was configured for a CI867, the CI867K01 is a hardware-compatible replacement that fits the same slot and uses the same backplane interface. However, you should verify that the firmware version of your PM861A, PM864A, or PM866A controller is compatible with the CI867K01 revision. A Control Builder M project update may be required to recognize the new module revision. NINERMAS recommends exporting a full project backup before any module swap.

Q2: What is involved in migrating from a CI854A (PROFIBUS DP) to the CI867K01 (PROFINET IO)?
A: This is a protocol migration, not a direct replacement. You will need to reconfigure all field devices from PROFIBUS DP to PROFINET IO, import GSDML files for each device, remap I/O signals in Control Builder M, and update any 800xA system topology and HMI configurations. NINERMAS can provide technical documentation and pre-shipment testing support to help plan the migration scope before the cutover window.

Q3: Does NINERMAS test CI867K01 modules before shipment, and what warranty is provided?
A: Yes. Every CI867K01 unit supplied by NINERMAS is functionally tested prior to shipment, with a test report included in the package. All modules are covered by a 12-month warranty from the date of shipment, covering manufacturing defects and functional failures under normal operating conditions. Replacement or repair is arranged promptly in the event of a warranty claim.

Q4: How quickly can NINERMAS ship the CI867K01 3BSE043660R1, and is stock available?
