PROFIBUS hardware installation
B.2.1.1. Bus nodes
Bus nodes connect one bus station with 2 other stations.
You might therefore refer to them as T-junctions as they provide
two cable connectors and a D-Sub plug that connects
to the bus station. They are delivered fully configured with
series inductances for cable type A.
To make connecting the bus cables easier, the connector
has 4 screw-type terminals, two for the incoming cable and
two for the outgoing one (see illustration).
