Table 129: CAN - Bus length and transfer rate
1) The specified cable length is only valid with the values specified in Tab. 66 "CAN driver settings" . Cable lengths additionally depend on the values in the
timing register.
The material used for the cable should have all or most of the following properties in order to achieve an optimal
transfer rate.

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 interface. The L1 LED status indicator indicates whether the
terminating resistor is enabled or disabled.
Terminating resistor
On The terminating resistor is enabled.
Off The terminating resistor is disabled.

3.4.6.3.4 Shielding
For the interfaces on the 10-pin female connector, the interface shield can be put on pin 2 of the female connector.
A functional ground connection, which can also be used for the cable shields, is located on the interface plate of
the system unit.
3.4.6.3.5 LED status indicators - L1, L2, L3
The interface option has 3 integrated LEDs located above the terminating resistor.

Status/Error LED
The Status/Error LED is a green and red dual LED. The LED status can have different meanings depending on
the operating mode.
