Description
B&R X20BC0087 Modbus TCP UDP Bus Controller

The B&R X20BC0087 connects X20 and X2X Link I/O modules to Modbus TCP or Modbus UDP networks. Its two external RJ45 ports and integrated switch simplify line wiring through multiple remote I/O stations.

The controller supports DHCP, BOOTP and configurable I/O cycles from 0.5 to 4 ms. Compared with protocol-specific real-time controllers such as X20BC00G3, the X20BC0087 is intended for broadly compatible Modbus applications rather than synchronized high-speed motion networks.

Key Features

  • Modbus TCP and Modbus UDP slave
  • Integrated Ethernet switch
  • 10/100 Mbit/s communication
  • 1 ms minimum fieldbus cycle
  • Configurable 0.5 to 4 ms I/O cycle
  • DHCP and BOOTP support

Typical Applications

  • Modbus TCP remote I/O
  • Process skids and utility equipment
  • Building and energy automation
  • Packaging and conveying machinery
  • Multi-vendor control systems

FAQ

Q: Is X20BC0087 a Modbus master?

A: No. It operates as a Modbus TCP or Modbus UDP slave and requires a compatible master.

Q: Can the two RJ45 ports be used for line wiring?

A: Yes. The integrated switch allows Ethernet connections to continue to another station.

Q: Does it support both TCP and UDP?

A: Yes. The controller supports Modbus communication over TCP/IP and UDP/IP.
