ABB CI570 MasterFieldbus Communication Module

Description

Key Technical Specifications

The CI570 is ABB’s MasterFieldbus Interface communication module for the Advant Controller family. It enables communication between the controller and MasterFieldbus networks used in legacy ABB DCS architectures. ABB documentation lists the CI570 as a supported communication option for the Advant Controller 450 platform, and it remains available as a lifecycle spare part for existing installations.

Product Introduction

The ABB CI570 (3BSE001440R1) is a MasterFieldbus communication interface designed for ABB Advant Controller systems. Installed as a communication submodule, it provides deterministic data exchange between the controller and the MasterFieldbus network, supporting distributed control applications in power generation, chemical processing, pulp and paper, and other continuous-process industries.

Although the Advant platform is now considered a legacy control system, thousands of installations remain in operation. For these systems, replacing a failed CI570 is generally far more practical than performing an unplanned migration of the entire DCS communication infrastructure. ABB continues to identify the CI570 as a lifecycle spare part for Advant Master systems.

Installation & Configuration Guide

Stage 1 – Pre-Installation Preparation

⚠️ Safety First

1. Notify operations of the planned shutdown.
2. Perform Lock-Out/Tag-Out procedures.
3. Remove cabinet power.
4. Wait at least 5 minutes for internal power supplies to discharge.
5. Wear an ESD wrist strap.

Required Tools

• Phillips screwdriver
• Digital multimeter
• ESD wrist strap
• Camera for recording wiring
• Identification labels

Before Removal

• Record controller configuration.
• Document communication settings.
• Photograph communication cables.
• Verify controller firmware revision.

Stage 2 – Removing the Existing Module

1. Remove controller power.
2. Disconnect communication cables.
3. Release retaining hardware.
4. Carefully withdraw the CI570.
5. Inspect connectors and backplane contacts.

⚠️ Keep the original module until the replacement has completed commissioning.

Stage 3 – Installing the New Module

1. Confirm the replacement is CI570 (3BSE001440R1).
2. Install the communication module fully into its slot.
3. Reconnect all communication wiring.
4. Verify connector seating.
5. Restore controller configuration if required.

Installation Checklist

• ✔ Correct model number
• ✔ Module fully seated
• ✔ Communication cables secure
• ✔ Controller recognizes module
• ✔ Network parameters verified

Stage 4 – Power-On & Testing

1. Restore controller power.
2. Observe diagnostic LEDs.
3. Verify MasterFieldbus communication.
4. Confirm all network nodes respond normally.
5. Monitor controller diagnostics for communication faults.

⚠️ Field Tip: On older Advant systems, communication failures after replacement are more often caused by incorrect network configuration or cable issues than by a defective replacement module.

Frequently Asked Questions

1. What is the CI570 used for?

The CI570 is a MasterFieldbus communication interface that connects ABB Advant Controllers to a MasterFieldbus network for controller-to-controller and distributed system communication.

2. Is the CI570 still manufactured?

No. It is considered a legacy Advant Master product. Most available units today are new surplus inventory or professionally tested refurbished modules.

3. Which controllers support the CI570?

The module is supported by ABB Advant Controller 450 and other compatible Advant Controller platforms that accept MasterFieldbus communication submodules.

4. Can the CI570 be replaced while the controller is powered?

No. ABB controllers using the CI570 are not designed for hot-swapping communication submodules. Always remove power before replacement to avoid communication faults or hardware damage.

5. Why does the controller report communication errors after replacement?

The most common causes include:

• MasterFieldbus address mismatch
• Incorrect communication configuration
• Loose backplane connection
• Damaged network cabling
• Controller firmware incompatibility

6. Is there a direct replacement?

For most legacy Advant Master installations, the CI570 (3BSE001440R1) remains the specified replacement. Before considering migration to newer communication technologies, verify controller hardware, firmware revision, and the overall lifecycle strategy for the DCS, as replacing the interface alone is often the most cost-effective maintenance approach.
