CAN Bus Setup
This section explains how to correctly configure the CAN bus. The following parameters
must first be set: Station number and data transfer rate.
CAN bus station number
Each CAN bus station is assigned its own station number. With this station number, data
can be exchanged with other stations connected to the bus. Up to 31 stations can be in-
stalled in a CAN bus system. However, each station number can only be assigned once.
CAN bus data transfer rate
The data transfer rate (baud rate) for the CAN bus can be set. However, the longer the
length of the bus, the smaller the transfer rate that must be selected.

These values are valid for the following cable: 120
, Twisted Pair.
NOTE: For the CAN bus protocol: 1 kbit/s = 1 kBaud.
