Example: Distributed structure
Several direct length measuring systems are used in a machine. These are to be combined
in a control cabinet and connected to the Control Unit via a DRIVE-CLiQ cable.
When a DMC20 is used, up to five measuring systems can be combined.
Figure 12-8 Example, distributed topology using DMC20
Using the hot-plugging function, components can be withdrawn from the operational drive
line-up (the other components continue to operate) on the DRIVE-CLiQ line. This means that
all of the drive objects or components involved must first be deactivated/parked using
parameter p0105 or STW2.7.
The following requirements must be satisfied:
Hot-plugging only functions when a drive object is connected in a star configuration to a
Control Unit or to the DRIVE-CLiQ Hub DMC20/DME20.
The system does not support removing DRIVE-CLiQ connections between the other DRIVE-
CLiQ components, e.g. Sensor/Terminal Module to Motor Module, Motor Module to Motor
Module.
