Terminating resistor
A terminating resistor is integrated in the interface option above the ETH1 interface. A switch is used to switch
the terminating resistor on or off for the CAN bus 1 interface. The L1 LED status indicator indicates whether the
terminating resistor is switched on or off. The terminating resistor cannot be switched on/off for the CAN bus 2
interface.
Terminating resistor
On
The terminating resistor is switched on.
Off
The terminating resistor is switched off.

Table 119: Terminating resistor
2.3.5.1.3.3 CAN bus 2 interface - Pinout
The CAN bus 2 interface on the system unit is referred to as IFx.
The terminating resistor cannot be switched on/off for the CAN bus 2 interface. A terminating resistor must therefore
be taken into account when wiring.

The CAN bus interface is a 10-pin female connector without electrical isolation.

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 IF4 in Automation Studio / Automation Runtime. It is not a "PC interface" and
therefore not shown in BIOS.
