Product Introduction
When your ABB System 800xA DCS and AC 800M control system needs a highly reliable dedicated communication unit to realize seamless data interconnection between the controller and third-party PLCs, power meters, variable frequency drives and intelligent field instruments, this kit acts as the core Modbus TCP protocol gateway.
It is a flagship high-performance Modbus TCP communication interface kit from ABB AC 800M series, specially designed for large industrial process control scenarios. It supports Modbus TCP master/slave dual mode, and is also compatible with Modbus RTU/ASCII protocol via RS-485 serial port. It is equipped with 2 independent 100Mbps full-duplex Ethernet ports, supporting network redundancy and hot-swap, with a maximum of 70 slave stations or 8 master stations per module, and up to 12 such modules can be mounted on the CEX bus. The complete kit includes the CI867 communication interface module and the matching TP867 baseplate, which can effectively share the communication load of the AC 800M CPU, and its industrial-grade wide temperature design fully adapts to harsh industrial site environments, making it a core replacement part for ABB DCS control system maintenance and retrofit projects.

Field Application & Technical Pitfalls
Critical Industrial Scenarios
- **Large Petrochemical Plant DCS System Third-Party Device Interconnection: Acts as the core Modbus TCP protocol gateway for ABB System 800xA DCS systems in petrochemical production plants, realizing seamless data exchange between AC 800M controllers and on-site power meters, variable frequency drives and third-party PLCs, ensuring the full data transparency of the production process control system.
- **Thermal Power Plant DCS System Auxiliary Equipment Communication: Delivers reliable high-load communication performance for power plant ABB DCS systems, adapting to long-term high-temperature operation industrial environments, meeting the stable data interconnection requirements between the main control system and a large number of auxiliary intelligent devices.
- **Metallurgical Factory Large Automation System Heterogeneous Equipment Integration: Adapts to high-vibration and high-dust metallurgical workshop environments, providing stable Modbus TCP communication support for the interconnection between ABB AC 800M controllers and various heterogeneous intelligent field instruments.
Non-Negotiable Technical Pitfalls
- ⚠️ Bold Warning 1: Never arbitrarily use non-matching non-TP867 standard baseplates for installation. The third communication channel will experience CEX-Bus signal deviation that causes the Modbus TCP connection to drop frequently.
- ⚠️ Bold Warning 2: Skipping the pre-commissioning full Modbus network performance test will leave you with hidden data transmission interruption risks. This kit must confirm the full network deterministic transmission performance fully meets ABB DCS communication specifications before putting into operation.
- ⚠️ Bold Warning 3: Do not arbitrarily configure the number of connected slave stations to exceed 70. The third communication channel will experience CPU overload that causes the module to crash and lose communication.
A large petrochemical plant maintenance team once swapped an ABB CI867K01 3BSE043660R1 kit and skipped the full network performance test. The hidden single communication channel slave station response timeout caused the power meter data to be lost, resulting in a 1-hour partial shutdown of the production unit.
Quality Control (QC) SOP & Transparency
- Inbound Verification: Cross-check the OEM serial number against ABB’s official AC 800M part registry, confirm the part number CI867K01 3BSE043660R1 matches the factory label, and inspect no bent pins or corrosion on all CEX-Bus backplane and Ethernet connectors.
- Live Rig Testing: Power the unit in a calibrated ABB AC 800M system test bench, simulate Modbus TCP multi-slave station communication scenarios, and confirm full 2-hour continuous stable 100Mbps data transmission operation.
- Parameter Testing: Verify the Modbus TCP master/slave dual mode communication performance meets factory specifications, confirm the data transmission packet loss rate is 0, and validate all status LED indicators and network diagnosis functions work properly.
- Final QA & Packaging: Seal the tested kit in a static-shielding anti-static bag, attach a unique QC passed serial label, and nest it in foam padding inside a rigid industrial shipping carton.
Frequently Asked Questions (FAQ)
- Can I hot-swap this module while the DCS control system is running? Yes, it supports AC 800M backplane hot-swap function, but you must first confirm that the redundant communication link is operating normally and has completed full data synchronization, then perform the replacement operation, otherwise you will trigger unexpected Modbus station communication interruption risks.
- What exact systems is this module compatible with? It works natively with ABB System 800xA and AC 800M series process control systems, and cannot be directly used in non-ABB DCS systems without custom protocol adaptation.
- How long is the standard warranty for this new surplus unit? 12 months from delivery. It covers all manufacturing defects, but does not extend to units damaged by miswiring, improper network parameter configuration, or overloading the number of slave stations in the field.
- How do I tell a genuine OEM unit apart from a refurbished clone? Genuine ABB CI867K01 3BSE043660R1 kits have a laser-etched part number on the PCB, not a printed sticker. Clone units almost always fail the full Modbus TCP multi-station continuous communication performance test.
- What is the typical lead time for shipment? In-stock units ship within 48 hours. If you require official ABB factory Modbus TCP communication performance test documentation, add 2 extra business days to the turnaround window.
- Can this module replace the older ABB legacy Modbus TCP communication unit? Well, technically it fits the same standard AC 800M CEX-Bus slot footprint, but you must confirm the AC 800M controller firmware version fully supports the module before replacement to ensure 100% system compatibility.
