More Information

Overview Manuals Network Setup Termination Replacement Application
  • Connects an X20 station as a CANopen slave
  • Supports automatic or fixed transfer-rate selection
  • Provides an integrated CANopen terminating resistor

X20BC0043 is a B&R canopen slave bus controller designed for the X20 System.

The controller couples an X20 I/O station to a CANopen network and manages fieldbus communication for the attached station modules.

Before installation or replacement, verify the complete material number, the exact legacy model without the -10 suffix, CANopen node and bit-rate settings, five-pin TB2105 connection, network termination, cable length and topology, X20PS9400 or X20PS9402, X20TB12, X20BB80, and the saved Automation Studio project.

Availability, condition, price, and shipping time for X20BC0043 are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • The CANopen node and transfer rate must match the network plan
  • Maximum distance depends on correct CAN topology and bit rate
  • The five-pin TB2105 connection must follow the documented pinout
  • The terminating resistor is integrated
  • Only the physical ends of the CAN segment should be terminated
  • Termination state should be checked during commissioning
  • The exact legacy catalog number must be confirmed
  • Do not import -10-only parameters without evidence
  • Back up the Automation Studio and CANopen configuration before exchange
  • Connecting distributed X20 I/O to a CANopen master
  • Maintaining legacy CANopen X20 stations
  • Replacing an exact X20BC0043 while preserving network configuration
Description
X20BC0043 is a B&R canopen slave bus controller for the X20 System.

Official B&R historical documentation identifies the exact X20BC0043 as a CANopen slave supporting up to 1000 m bus distance, up to 1 Mbit/s transfer, automatic or fixed bit-rate selection, and an integrated terminating resistor.

Before installation or replacement, confirm the complete material number, the exact legacy model without the -10 suffix, CANopen node and bit-rate settings, five-pin TB2105 connection, network termination, cable length and topology, X20PS9400 or X20PS9402, X20TB12, X20BB80, and the saved Automation Studio project.

Technical notes
X20BC0043 is a legacy CANopen slave bus controller. Do not substitute X20BC0043-10 specifications automatically; verify the exact catalog number, five-pin CANopen terminal, node and bit-rate configuration, termination, power-supply module, bus base, terminal block, and saved project before replacement.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Is B&R X20BC0043 the same product as X20BC0043-10?
No. X20BC0043 is a legacy exact catalog number and X20BC0043-10 is a later distinct model. Confirm the label and use exact-model documentation for replacement decisions.
What should be backed up before replacing B&R X20BC0043?
Save the Automation Studio project, CANopen node ID, transfer rate, PDO mapping, I/O configuration, diagnostics, and station power layout.
Why can a replacement B&R X20BC0043 remain offline on CANopen?
Check the node ID, bit rate, five-pin terminal wiring, cable polarity, shield, segment length, topology, termination, and master configuration.
How should the integrated terminator on B&R X20BC0043 be used?
Enable termination only when the controller is at a physical end of the CAN segment; duplicate or missing termination can destabilize communication.
Can B&R X20BC0043 use any X20 power module?
No. Official historical documentation lists X20PS9400 or X20PS9402 together with X20TB12 and X20BB80; verify the complete assembly.
What determines the usable cable distance for B&R X20BC0043?
The CAN bit rate, cable type, topology, stubs, termination, grounding, and EMC environment determine the practical distance; 1000 m is the documented maximum.
What should be checked when CANopen errors appear intermittently on B&R X20BC0043?
Inspect supply stability, connectors, shield and ground, termination, duplicate node IDs, bus loading, error counters, cable routing, and the master diagnostics.
