DRIVE-CLiQ topology
NX components can be connected to the Control Unit via DRIVE-CLiQ. The following rules
apply for the wiring:
Only one star topology is permitted between the NX and the Control Unit. This means
that only one NX can be operated per DRIVE-CLiQ port on a Control Unit.
DRIVE-CLiQ ports not assigned to NX can be wired to other DRIVE-CLiQ components.
Once an NX has been connected and configured, you cannot simply insert it into a
different DRIVE-CLiQ port, as the addresses of the integrated drives are set permanently
from the point of view of the PLC. The following table illustrates this relation:
