Example of the required topology
You can see an example created with STARTER below. 3 Basic Line Modules, 2 Motor
Modules and an auxiliary drive are configured. The parallel connections can be clearly seen
in the topology tree as one infeed and one drive. You can also see the additional auxiliary
drive. The DRIVE-CLiQ connections are shown as a thin line. The three parallel Line
Modules are connected to one DRIVE-CLiQ line, the two Motor Modules to the next DRIVE-
CLiQ line, and the auxiliary drive to a third line.
