ABB CI854AK01 3BSE030220R1 PROFIBUS-DP/V1 Communication Interface

Description

ABB CI854AK01 3BSE030220R1 – PROFIBUS-DP/V1 Communication Interface

Product Introduction

The ABB CI854AK01 3BSE030220R1 is a PROFIBUS-DP/V1 communication interface for ABB AC 800M controller systems used within System 800xA and related control architectures. Its primary purpose is to connect the AC 800M controller to PROFIBUS field devices, including remote I/O, drives, electrical equipment, and other PROFIBUS-capable devices. The CI854A operates as a PROFIBUS master and provides two PROFIBUS communication ports, allowing line redundancy to be implemented where the system architecture requires it. ABB documentation specifies communication speeds from 9.6 kbit/s through 12 Mbit/s.

The ABB CI854AK01 3BSE030220R1 is supplied as a package consisting of the CI854A communication interface and TP854 baseplate. The interface connects to the AC 800M controller through the CEX-Bus, while the TP854 provides the physical PROFIBUS connections. ABB lists both PROFIBUS line redundancy and communication-module redundancy as supported functions. Master redundancy can be implemented using two CI854A modules, which can also be combined with CPU and CEX-Bus redundancy in appropriately engineered AC 800M systems.

The ABB CI854AK01 3BSE030220R1 is now a classic/legacy product rather than ABB’s preferred choice for new installations. ABB’s product documentation explicitly states that this version is intended as a spare for existing systems and identifies CI854BK01, 3BSE069449R1 as the replacement for new installations. This distinction matters when planning a system expansion: replacing a failed CI854A in an established project is different from designing a new PROFIBUS interface around the current CI854B generation.

Technical Specifications

ABB’s System 800xA catalog confirms the CI854AK01 article number and PROFIBUS-DP interface function, while the CI854A hardware selector provides the two-port, speed, redundancy, connector, and power-consumption information.

Main Features and Engineering Considerations

PROFIBUS-DP Master Interface

The primary function of the is PROFIBUS master communication. It provides the AC 800M controller with access to distributed PROFIBUS devices rather than performing conventional local analog or digital I/O itself. This makes it particularly useful in installations where field devices or remote I/O remain on PROFIBUS while the primary control logic resides in the AC 800M controller.

Two PROFIBUS Ports

The provides two PROFIBUS ports and supports line redundancy. This is useful in installations where communication availability is important and the network has been engineered around redundant PROFIBUS paths. ABB also documents master redundancy using two modules.

Do not confuse two PROFIBUS ports with two independent controllers. The module is still a communication interface attached to the AC 800M architecture. The actual redundancy behavior depends on the controller configuration, CEX-Bus arrangement, network topology, and Control Builder project.

AC 800M Integration

The is designed specifically for the AC 800M platform. It communicates with the controller over the CEX-Bus and is mounted using the applicable baseplate arrangement. ABB documentation identifies support across several AC 800M/System 800xA hardware and software generations.

During replacement, verify the controller hardware revision and project/software version instead of assuming that every AC 800M controller installation is interchangeable.

Legacy Lifecycle

This is one of the most important procurement considerations. ABB identifies as a spare-part item for existing installations and states that it is not intended for new installations. ABB specifies CI854BK01, 3BSE069449R1 for new installations.

For a plant with an established network, however, retaining the exact spare can still be the most practical option when minimizing software changes, network revalidation, and commissioning work is more important than modernization.

Application Scenarios

• ABB AC 800M controller systems
• ABB System 800xA process-control installations
• PROFIBUS-DP remote I/O networks
• PROFIBUS-connected drives
• Distributed field instrumentation
• Electrical equipment using PROFIBUS-DP
• Redundant PROFIBUS communication architectures
• Maintenance of legacy AC 800M installations

Engineer’s Guide: Field Pitfalls

1. Do not confuse with CI853 or CI867.
CI853 is an RS-232 communication interface, while CI867 is a MODBUS TCP interface. is specifically the PROFIBUS-DP interface. ABB’s catalog separates these communication modules by protocol.

2. Check whether the application requires or CI854B.
The is the classic version. ABB identifies CI854BK01 / 3BSE069449R1 as the replacement for new installations. Do not substitute purely based on physical appearance.

3. Verify the TP854 baseplate.
The complete package includes the TP854 baseplate. If purchasing only a communication module, verify exactly what is included in the offered item.

4. Check PROFIBUS termination.
ABB specifically notes that the PROFIBUS network must be terminated at the two outermost nodes. Improper termination can produce intermittent communication problems that may initially look like a defective .

5. Verify redundancy architecture.
A two-port does not automatically mean the entire network is redundant. Check the actual topology, controller redundancy, CEX-Bus configuration, PROFIBUS cabling, and engineering configuration.

Frequently Asked Questions

What is ABB ?

It is an AC 800M PROFIBUS-DP/V1 communication interface. It operates as a PROFIBUS master and connects the AC 800M controller to PROFIBUS field devices.

What is the ABB part number?

The ABB Product ID is 3BSE030220R1, with type designation .

How many PROFIBUS ports does have?

The has two PROFIBUS ports, supporting line redundancy.

What communication speed does it support?

The documented transmission range is 9.6 kbit/s to 12 Mbit/s.

Is still suitable for new AC 800M installations?

ABB classifies this version as a classic/legacy spare and recommends CI854BK01, 3BSE069449R1 for new installations.

What does the package contain?

The documented package contains the communication interface and TP854 baseplate.

Procurement Note

For ABB 3BSE030220R1, the complete part number should be treated as the purchasing reference. Before accepting a replacement, verify:

• designation
• 3BSE030220R1 order number
• hardware revision
• baseplate availability
• AC 800M controller generation
• Control Builder/System 800xA version
• PROFIBUS network topology
• Redundancy requirements
• Existing PROFIBUS device configuration
• Module condition and diagnostic test results

For an existing plant, an exact spare can be preferable to an immediate migration to CI854B because changing the communication interface may introduce engineering and validation work. For a new system design, however, ABB’s own documentation points toward CI854BK01 / 3BSE069449R1 rather than the legacy .
