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 211)).
Whereby 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).
