1) The interfaces, etc. available on the device or module have been numbered as such for easy identification. This numbering may differ from that used by
the particular operating system.
2) This interface (if available) is enabled automatically in BIOS as CAN with default I/O address 384h/385h and IRQ 10.

The baud rate can be set in Automation Studio either with predefined values or with the bit timing register. More
information on this can be found in the Automation Studio help system.

CAN - Bus length and cable type
The type of cable used depends largely on the required bus length and the number of nodes. The bus length is
mainly determined by the bit rate. In accordance with CiA (CAN in Automation) the maximum bus length is 1000
meters.
The following bus lengths are permitted with a maximum oscillator tolerance of 0.121%:
