Description:
  • Fieldbus: CAN bus
  • Automatic firmware update via the fieldbus
  • Integrated I/O access in B&R Automation Studio
  • Integrated terminating resistor

The bus controller makes it possible to connect X2X Link I/O nodes to CAN I/O. CAN I/O is a transfer protocol based on standard CAN bus that is fully integrated in the B&R system.

Up to 43 logic I/O modules can be connected to the bus controller. Up to 16 of them can be analog modules.
