B&R X20BR7300
Fieldbus: CAN bus Automatic firmware update via the fieldbus Integrated I/O access in B&R Automation Studio The bus receiver 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 logical I/O modules can be connected to the bus receiver. Up to 16 of these can be analog modules.
