ABB CI854B PROFIBUS DP Communication Interface Module for AC 800M

Technical Specifications Breakdown

• Communication Protocol: PROFIBUS DP-V1 — a widely adopted fieldbus standard for deterministic data exchange.
• Transmission Speed: 9.6 – 12,000 kbit/s, allowing flexible integration with devices of varying speed requirements.
• Number of Channels: 2, enabling redundant line topology for increased network reliability.
• Master Redundancy: Supported via two CI854B modules, which can be combined with CPU redundancy and CEXbus redundancy (BC810) for mission-critical applications.
• Hot Swap: Yes — replace a module without powering down the system, minimizing downtime.
• Power Consumption: 190 mA typical at 24 V DC.
• Operating Temperature: 0 to +55 °C (+32 to +131 °F), suitable for industrial environments.
• Protection Class: IP20 per EN60529, IEC 529.
• Dimensions: 59 mm wide x 185 mm high x 127.5 mm deep; weight 700 g including base.

Industry Applications

In a water treatment plant, for example, redundant CI854B modules ensure continuous communication between the AC 800M controller and remote pump stations, preventing costly shutdowns.

Installation & Setup Guidance

Mount the CI854B on a DIN rail using the included TP854 baseplate. The module interfaces directly with the S800 I/O system and other PROFIBUS DP/DP-V1 and FOUNDATION Fieldbus systems. For proper termination, install connectors with built-in termination at the two outermost nodes of the PROFIBUS DP segment. Ensure the connector is plugged and powered to guarantee correct termination. Verify compatibility with System 800xA 6.0.3.2 and Compact Control Builder 6.0.0-2 or later.

Maintenance & Reliability

Periodically inspect the module for dust accumulation and ensure ventilation around the IP20 enclosure. The CI854B operates reliably in environments with pollution degree 2 per IEC/EN61131-2 and is G3 corrosion protected per ISA 71.04. Its hot swap capability allows replacement without system downtime, reducing maintenance costs. For safety-critical applications, follow the manufacturer's safety manual during inspection and testing.

What Is the ABB CI854B?

This PROFIBUS DP-V1 master communication interface connects remote I/O, drives, low voltage electrical equipment, and controllers to the AC 800M system. With two PROFIBUS ports, it supports line redundancy and PROFIBUS master redundancy, ensuring continuous operation even if one path fails.

Compatibility & Integration

The CI854B connects to the AC 800M controller and supports PROFIBUS PA via the LD 800P linking device. It works with HI Controllers and can be used with up to 12 units on the CEX bus. The module is CE marked, carries marine certificates (ABS, BV, DNV-GL, LR), and complies with EU, UAE, and CN RoHS as well as WEEE Directive 2012/19/EU.

Selection Guide & Purchasing Advice

Before ordering, confirm your system software version meets the minimum requirements (System 800xA 6.0.3.2, Compact Control Builder 6.0.0-2). The package includes the CI854BK01 Communication Interface and TP854 Baseplate. For master redundancy, you will need two CI854B modules.
