Functional description

5.2.3 CAN-Bus settings [CANBus1] / [CANBus2]

5.2.3.1 [BaudRate]

There are three possibilities for setting the baudrate.

1. Automatic baudrate detection (BaudRate=Auto):

The status diagram (Fig. 4-1) shows the function of the automatic baudrate

detection.
Note: The baudrate can only be detected if there is bus traffic and at least

two nodes per segment are active.
