Connecting infeed units in parallel
To connect infeed units (Line Modules) in parallel with already added modules, proceed as
follows:
1. Open "Line Modules" in the hardware catalog.
2. If you have not yet inserted any infeed unit, drag the desired, non-specified infeed unit
into the device view and specify this infeed unit (refer to Chapter "Specifying an infeed
unit (Page 94)").
3. Drag a non-specified infeed unit into the DRIVE-CLiQ editor in the light gray area of the
existing infeed unit.
Figure 4-13
Then also specify the infeed unit connected in parallel (refer to Chapter "Specifying an
infeed unit (Page 94)").
You can connect further infeed units in parallel in the same manner.
Result:
The infeed unit connected in parallel is inserted and specified. The white area turns gray.
The infeed units are linked with one another via interfaces X201 and X200.
Note
If required, parallel connection can be activated or deactivated for individual infeed units via
the inspector window (Line Module_xx/drop-down list "Component activation").
For deactivation, the respective infeed unit must be disconnected from the network (using a
contactor, for example). Motor supply cables must be opened.
