4.5.6.1 General information
The X20BC0073 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 fully integrated in the B&R system. From the user's point of view, it doesn't
matter if I/O points are operated locally or remotely via CAN I/O.
Up to 43 I/O modules can be connected to the bus controller. Up to 16 of them can be analog modules.
•
Fieldbus: CAN bus
•
Automatic firmware update via the fieldbus
•
Integrated I/O access in B&R Automation Studio
•
Integrated terminating resistor
Information:
The bus controller is unable to detect modules after a gap in the X2X Link station numbers. This can
be caused by:
•
X20 modules not being connected
•
Modules with integrated node number switch, such as the X20BM05
Information:
Only the standard function model (see the respective module description) is supported when the bus
controller is used together with multi-function modules it has automatically configured itself.
