CX32-2 DRIVE-CLiQ topology
In contrast to other DRIVE-CLiQ components (e.g. terminal modules), special rules apply
when wiring the CX32-2.
● Only a point-to-point topology is possible between the CX32-2 and SIMOTION D. Each
CX32-2 needs its own DRIVE-CLiQ port on the SIMOTION D control unit.
● When a CX32-2 is inserted in an existing DRIVE-CLiQ connection (target port for CX32-2
is occupied, e.g. by a TM31), this connection is disconnected and replaced by the
CX32-2 connection. The component that is freed up is moved to the component archive
of the SINAMICS topology overview. A notice is displayed indicating that the component
has been moved to the archive. The components must then be reassigned.
● A CX32-2 is inserted via HW Config (see Section Configuration of a CX32-2 (Page 194)).
Whe
reby the selection made for the PROFIBUS address automatically and permanently
assigns the DRIVE-CLiQ port for connecting the CX32-2. Given that this assignment is
permanent, the following points must be noted:
– An inserted and configured CX32-2 cannot be connected to another DRIVE-CLiQ port
without taking additional measures. Reconnecting a CX32-2 results in a discrepancy
between the specified and actual topologies of the DRIVE-CLiQ components.
– A cross-exchange of two occupied DRIVE-CLiQ ports is not permitted. Such an
exchange results in inconsistencies in the specified-actual topologies.
– Once it has been created in HW Config, the connecting port of a CX32-2 cannot be
changed.
– To change the connecting port of a CX32-2, the CX32-2 must be deleted from HW
Config and recreated with another address.
– To delete a CX32-2, it must be deleted from HW Config and then the configuration
saved and compiled.
– It is not possible to replace a control unit with six DRIVE-CLiQ ports (D435-2, D445-2
or D455-2) with a control unit with four DRIVE-CLiQ ports (D425-2) when a CX32-2
has been configured with address 14 or 15 (a control unit with four DRIVE-CLiQ ports
does not have the DRIVE-CLiQ ports X104/X105 and consequently not the addresses
14 and 15).
– The previous CX32 version cannot be used on a D4x5-2, see Section Permissible
combi
nations (Page 306) in Migration of D4x5 to D4x5-2.
