Technical data
2.3.5.1.3.2 CAN bus 1 interface - Pinout
The CAN bus 1 interface on the system unit is referred to as IFx.
A terminating resistor can be enabled or disabled for the CAN bus 1 interface. The L1 LED status indicator indicates
whether the terminating resistor is switched on or off.
The electrically isolated CAN bus interface is a 10-pin female connector.

1) The interfaces, etc. available on the device or module have been numbered as such for the purpose of clear differentiation. This numbering may deviate
from the numbering used by the respective operating system, however.
2) This interface can only be used in Automation Runtime and is referred to as IF3 in Automation Studio / Automation Runtime. It is not a "PC interface" and
therefore not shown in BIOS.
CAN driver settings
The baud rate can be set either with predefined values or the bit timing register. For additional information, see
Automation Help.

CAN1 - Bus length and cable type
The type of cable to be used depends largely on the required bus length and number of nodes. The bus length is
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%:
Extension
≤1000 m
≤200 m
≤100 m
