number (depending on the component type) are not checked, as the HW version, for example,
is coded in these. This mechanism is also applied when several components are replaced.
Modified wiring following module replacement
In the default setting for the topology comparator, modified wiring configurations of the DRIVE-
CLiQ components (e.g. a cross-exchange) are not accepted for safety reasons and are
generated by a fault.
If a cross-exchange of components is required (i.e. existing components are replaced with
other existing components, and no spare parts are used), e.g. for troubleshooting purposes,
the topology comparator must be reduced via parameter p9906, or preferably via p9907/p9908;
alternatively, by right-clicking in the topology.
Note
In this case, incorrect insertion of components is no longer monitored.
Automatic upgrading/downgrading (firmware update)
When starting up, the system automatically upgrades or downgrades all DRIVE-CLiQ
components to the version of the component firmware on the CF card. Components that cannot
be downgraded to the component firmware version on the CF card (for example, old firmware
on the CF card and new components to which the old firmware cannot be loaded) retain their
firmware version. The resulting firmware version combinations are always functional.
The component version can be obtained from the CONTENT.TXT file in the main directory of
the CF card.
Note
During an automatic FW update, please take note of the messages and alarms in the
SIMOTION SCOUT detail window.
An FW update on the D410 is signaled by the RDY LED flashing yellow, while on the DRIVE-
CLiQ components (TM, SMC, etc.) it is signaled by the RDY LED flashing red/green.
● FW update running: RDY LED flashes slowly (0.5 Hz)
● FW update complete: RDY LED flashes quickly (2 Hz)
Go offline once all the FW updates are complete, then switch the 24 V supply for the upgraded/
downgraded initialization components off/on.
The update function can be deactivated using CU parameter p7826 in the expert list.
