Terminating resistor
A terminating resistor is integrated in the interface option above the ETH1 interface. A switch is used to enable
or disable the terminating resistor for the CAN bus 1 interface. The L1 LED status indicator indicates whether the
terminating resistor is enabled or disabled. The terminating resistor cannot be enabled/disabled for the CAN bus
2 interface.
Terminating resistor
On
The terminating resistor is enabled.
Off
The terminating resistor is disabled.
Table 69: Terminating resistor
3.4.1.3.3 CAN bus 2 interface - Pinout
The CAN bus 2 interface on the system unit is referred to as IFx.
The terminating resistor cannot be enabled/disabled for the CAN bus 2 interface. A terminating resistor must there-
fore be taken into account when wiring.

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 can only be used in Automation Runtime and is referred to as IF4 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 in Automation Studio either with predefined values or with the bit timing register. For
additional information, see Automation Help.
