11.4 Application examples with the DMC20
11.4.1 Features
The DRIVE-CLiQ Hub Module Cabinet 20 (DMC20) has the following features:
● Own drive object
● 6 DRIVE-CLiQ ports
● Own faults and alarms
Typical applications would include:
● Implementation of a distributed topology via a DRIVE-CLiQ cable
● Hot plugging (a DRIVE-CLiQ connection is withdrawn in operation)
11.4.2 Description
The DRIVE-CLiQ Hub Module Cabinet 20 (DMC20) is used for the star-shaped distribution
of a DRIVE-CLiQ line. With the DMC20, an axis grouping can be expanded with four DRIVE-
CLiQ sockets for additional subgroups.
The component is especially suitable for applications which require DRIVE-CLiQ nodes to be
removed in groups, without interrupting the DRIVE-CLiQ line and therefore the data
exchange.
11.4.3 Example, distributed topology
Description
Several direct length measuring systems are used in a machine. These are to be combined
in an electrical cabinet and connected to the Control Unit via a DRIVE-CLiQ cable.
When using a DMC20, up to five measuring systems can be combined. The measuring
systems are not assigned directly to the drive objects. Instead, they must be assigned to the
drive objects in the topology view in STARTER.
