The ABB CI873 is a powerful Ethernet Communication Interface module designed for the AC 800M controller within the ABB Ability System 800xA distributed control system. It's a critical component for enabling high-speed, reliable communication between the controller and various devices and networks in an industrial environment.

Product Description

The CI873 is a communication interface that primarily connects the AC 800M controller to external Ethernet devices using EtherNet/IP and DeviceNet protocols. This module provides robust and flexible connectivity options for demanding industrial applications.

It's designed to seamlessly integrate into the AC 800M controller's CEX-Bus, expanding its communication capabilities. The CI873 typically features two RJ45 Ethernet connectors (though only one, CH1, might be used for 100Mbps communication in certain configurations, as seen in the CI873A variant). Its architecture includes the CEX-Bus logic, a communication unit, and a DC/DC converter, drawing power from the +24V supply via the CEX-Bus. This design ensures stable power delivery and reliable operation.

A significant feature of the CI873 is its support for module redundancy, which enhances system availability by allowing a hot-swappable replacement without interrupting operations. It can also support up to 6 redundant pairs of CI873A modules from System 800xA 5.1 FP4 onwards, indicating its scalability for large, critical systems.

Product Specifications (Based on common CI873/CI873A variants)

• Manufacturer: ABB
• Model Name: CI873 (often seen as CI873A or CI873-K01, with slight variations in part numbers like 3BSE056899R2 for the CI873-K01 kit or 3BSE092695R1 for CI873A).
• Product Type: Ethernet Communication Interface Module
• Ports: Typically two RJ45 Ethernet connectors (e.g., on the associated baseplate like TP867).
• Compatibility: Designed for use with ABB AC 800M controllers within the ABB Ability System 800xA platform.
• Communication Protocols: Supports EtherNet/IP and DeviceNet protocols.
• Master/Slave Role: Functions as a Master.
• Data Rate: 10/100 Mbit/s.
• Redundancy: Supports module redundancy (hot-swappable). Does not support line redundancy.
• Power Consumption (Typical): Around 160 mA from a 24V supply.
• Physical Dimensions (Approximate for the module itself):
• Depth: 185 mm (7.3 in.)
• Height: 127.5 mm (5.0 in.)
• Width: 20 mm (0.8 in.)
• Weight (including base): Approximately 0.4 kg (0.88 lbs).
• Environmental:
• Operating Temperature: +5 to +55 °C (+41 to +131 °F).
• Storage Temperature: -40 to +70 °C (-40 to +158 °F).
• Relative Humidity: 5 to 95 %, non-condensing.
• Protection Class: IP20.
• Certifications: CE-marking, UL 61010-1, UL 61010-2-201, UL 60079-15 (for hazardous locations: cULus Class 1, Zone 2), DNV-GL marine certificates.

• Software Compatibility: Requires specific System 800xA versions (e.g., CI873A from 5.1 FP4, and works with 6.0.3.3, 6.1.1 and subsequent versions).

The CI873A is an AC 800M communication interface that connects to external Ethernet devices using the EtherNet/IP protocol. The TP867 Baseplate has two RJ45 Ethernet connectors, but only the CH1 connector that supports 100Mbps is used. The CI873 expansion unit contains the CEX-Bus logic, a communication unit, and a DC/DC converter that supplies the required voltage from +24 V supply through the CEX-Bus.

The CI873A module will only work with System 800xA 6.0.3.3, 6.1.1 and subsequent versions. The CI873A support 6 redundant pairs of CI873A from 5.1 FP4

Product Application Cases

The ABB CI873 is a vital communication link in complex industrial automation environments where robust and flexible networking is essential for control, monitoring, and data exchange.

• Process Control Systems: In large-scale industries like oil and gas, petrochemicals, power generation, and chemical processing, the CI873 connects AC 800M controllers to plant-wide Ethernet/IP and DeviceNet networks. This facilitates real-time data exchange between controllers, intelligent field devices (like smart sensors and actuators), and higher-level systems (SCADA, MES), enabling precise control and optimization of critical processes.
• Factory Automation: In discrete manufacturing, automotive production, and general assembly lines, it allows AC 800M controllers to communicate with various factory floor devices and systems, including robotic cells, machine vision systems, and conveyor controls. This ensures synchronized operations and efficient material flow.
• Distributed Control Systems (DCS): As an integral part of System 800xA, the CI873 supports distributed control architectures, enabling controllers located in different areas of a plant to communicate and coordinate over a unified network.
• Remote I/O and Device Integration: It acts as a gateway for integrating remote I/O devices or third-party equipment that communicate via EtherNet/IP or DeviceNet into the ABB control system, extending the reach and capabilities of the main controller.
• Safety and Interlock Systems: While not a safety controller itself, reliable communication via the CI873 is critical for transmitting status and command signals in complex interlock and shutdown systems within industrial facilities.
