Comparison of topologies at Power On
Comparing the topologies prevents a component from being controlled/evaluated incorrectly
(e.g. drive 1 and 2).
When the drive system boots, the Control Unit compares the detected actual topology and
the electronic rating plates with the target topology stored on the memory card.
You can specify how the electronic rating plates are compared for all the components of a
Control Unit via p9906. The type of comparison can be changed subsequently for each
individual component. You can use p9908 for this or right-click in the topology view in the
STARTER tool. All data on the electronic rating plate are compared by default.
The following data in the target and actual topologies is compared depending on the settings
made in p9906/9908:
● p9906/p9908 = 0 component type, order number, manufacturer, serial number
● p9906/p9908 = 1 component type, order number
● p9906/p9908 = 2 component type
● p9906/p9908 = 3 component class (e.g. Sensor Module or Motor Module)
