4. Product Introduction

The ABB BC810 (3BSE031154R1) is a CEX-Bus Interconnection Unit designed for the ABB AC 800M controller family within the System 800xA automation platform. It divides the CEX-Bus into independent communication segments, allowing redundant controller configurations and supporting high-availability process control architectures.

The BC810 is commonly installed in power generation, oil and gas, chemical processing, and other continuous-process industries where controller redundancy and online maintenance are essential. It supports hot-swapping of CPUs, helping minimize production downtime during controller replacement or maintenance.

5. Installation & Configuration Guide

 

Stage 1 – Pre-Installation Preparation (10 Minutes)

⚠️ Safety First

  1. Notify plant operations before maintenance.
  2. Place the controller in a safe operating state.
  3. Apply Lock-Out/Tag-Out (LOTO).
  4. Remove cabinet power if the maintenance procedure requires it.
  5. Wear an ESD wrist strap before handling the module.

Required Tools

  • Phillips screwdriver
  • ESD wrist strap
  • Digital multimeter
  • Cable labels
  • Smartphone for wiring documentation

Backup Tasks

  • Back up the AC 800M project.
  • Record controller redundancy status.
  • Photograph all CEX-Bus cable connections.
  • Verify controller firmware versions.

 

Stage 2 – Removing the Existing BC810

  1. Label every CEX-Bus cable.
  2. Disconnect the TK851 interconnection cable.
  3. Remove the TB850 bus terminator if required.
  4. Release the mounting mechanism.
  5. Remove the BC810 carefully from the baseplate.

⚠️ Inspect the CEX-Bus connectors before installing the replacement module.

 

Stage 3 – Installing the New BC810

  1. Verify the replacement part number (3BSE031154R1).
  2. Install the BC810 onto the TP857 baseplate.
  3. Connect the TK851 interconnection cable.
  4. Install the TB850 CEX-Bus terminators.
  5. Verify all connectors are fully seated.

Installation Checklist

  • ✔ Correct module installed
  • ✔ Baseplate secure
  • ✔ CEX-Bus cable connected
  • ✔ Terminators installed
  • ✔ 24 VDC power verified

 

Stage 4 – Power-Up & Commissioning

  1. Restore 24 VDC power.
  2. Verify controller startup.
  3. Confirm CEX-Bus communication.
  4. Verify redundancy synchronization.
  5. Check controller diagnostics.
  6. Perform a redundancy switchover test if permitted by plant procedures.

⚠️ Troubleshooting

No CEX-Bus Communication

Check:

  • TK851 cable installation
  • TB850 terminators
  • Baseplate connections
  • 24 VDC power supply

Redundancy Not Established

Verify:

  • Matching controller firmware
  • Correct redundancy configuration
  • CEX-Bus integrity
  • Controller addressing

 

6. Frequently Asked Questions (FAQ)

Q1. What is the purpose of the BC810?

The BC810 is a CEX-Bus interconnection unit that divides the communication bus into separate segments for redundant AC 800M controller configurations. It enables high system availability and supports online CPU replacement.

Q2. Does the BC810 support hot-swapping?

Yes. One of its primary functions is supporting hot replacement of AC 800M CPUs while maintaining CEX-Bus communication in redundant systems.

Q3. Which systems use the BC810?

The BC810 is designed for ABB AC 800M controllers operating within ABB System 800xA architectures that require CEX-Bus redundancy.

Q4. What components are included in the BC810 kit?

A standard BC810K02 kit includes:

  • 2 × BC810 interconnection units
  • 2 × TP857 baseplates
  • 1 × TK851 interconnection cable
  • 2 × TB850 CEX-Bus terminators

Q5. Is the BC810 suitable for high-availability systems?

Yes. It is specifically engineered for redundant AC 800M controller configurations, making it suitable for applications where continuous operation and minimal downtime are required.

Q6. What should I verify before replacing a BC810?

Before replacement, verify:

  • Exact part number (3BSE031154R1)
  • Controller firmware compatibility
  • CEX-Bus cable routing
  • Redundancy configuration
  • 24 VDC power supply
  • TK851 cable and TB850 terminator condition

Taking photos of the existing installation before removal is recommended, as it significantly reduces commissioning time and helps prevent CEX-Bus wiring errors.
