ABB CI867 (3BSE043661R1) – PROFINET communication interface module for AC 800M / System 800xA

The ABB CI867 (part number 3BSE043661R1) is a communication interface module designed to bring PROFINET IO connectivity to AC 800M controllers within System 800xA. From my experience, it’s typically used when an existing AC 800M needs to talk directly to PROFINET-based remote I/O, drives, and smart devices without adding a separate gateway. You might notice that it streamlines engineering too—device setup via GSDML is straightforward and diagnostics flow neatly into Control Builder/800xA.

Key Features

• PROFINET IO (RT) connectivity – Typically used as a PROFINET IO Controller for AC 800M to interface with PROFINET remote I/O, drives, and HMIs.
• Dual RJ45 Ethernet ports – 10/100Base‑T(X) with a built-in 2‑port switch for easy line or star topologies using shielded copper.
• Integrated diagnostics – Device/alarm diagnostics are accessible from Control Builder / 800xA, which seems to reduce troubleshooting time on site.
• GSDML-based device integration – Fast device import and parameterization; in many cases you can reuse existing project libraries.
• Industrial robustness – Designed for cabinet installation in typical plant environments; supports shield bonding and grounding practices for EMC.
• CEX-bus module – Powered and managed via the AC 800M CEX-bus, avoiding external, dedicated power supplies.

Technical Specifications

Application Fields

The CI867 is a practical choice when standardizing on PROFINET across:

• Packaging lines with PROFINET remote I/O and servo drives
• Material handling and intralogistics (VFDs, barcode readers, safety I/O via PN)
• F&B and pharma skids where OEM modules come PROFINET-ready
• Brownfield upgrades migrating from legacy fieldbuses to Ethernet-based I/O

A packaging OEM told us they swapped a gateway setup for CI867 on an AC 800M and shaved roughly a third off their panel wiring time, mainly because device commissioning moved into one engineering environment.

Advantages & Value

• Native integration – Works within the 800xA/AC 800M ecosystem, so engineering and diagnostics stay consistent.
• Reduced hardware – No extra gateways in most cases; fewer potential points of failure, easier spares.
• Future-friendly – PROFINET IO is widely supported by I/O, drives, and instrumentation vendors, simplifying multi‑brand projects.
• Support and lifecycle – ABB’s long lifecycle support for AC 800M modules typically keeps fleets maintainable for years.

Installation & Maintenance

• Cabinet environment – Install on DIN‑rail inside a ventilated control cabinet. Keep ambient typically within 0…55 °C and non‑condensing humidity.
• Wiring – Use shielded Cat5e/Cat6 industrial Ethernet. Bond shields 360° at the cabinet entry where possible. Maintain proper grounding to reduce EMC issues.
• Topology – For most machines, a line topology via the dual‑port switch works well; for higher availability, consider ring redundancy where supported in your firmware.
• Safety – De‑energize the system before insertion/removal. Observe ESD precautions when handling the module.
• Routine care – Periodically check connector tightness, clean dust filters, and review event logs in 800xA. Plan firmware updates during scheduled downtime after validation.
• Supporting components – Typical accessories include the AC 800M CEX‑bus connection cable, DIN‑rail base, and pre‑made shielded RJ45 patch cords.

Quality & Certifications

• Manufacturer certifications commonly include CE and UL for industrial control equipment; RoHS/REACH compliance is typically available for ABB modules.
• Standard manufacturer warranty applies; our provided warranty coverage is 365 days from delivery.

Note: CI867 3BSE043661R1 appears to be a later hardware revision within the CI867 family. If you are matching an existing installed base (or enabling specific features like redundancy modes), share your firmware target and topology so we can confirm compatibility before shipment.
