7.24 Upgrade the firmware and project
Once the project has been downloaded or automatic configuration has been carried out, the
firmware is automatically upgraded on all the connected DRIVE-CLiQ components. This
upgrades all DRIVE-CLiQ components to the firmware releases that match the memory card.
Update
This operation can take several minutes. This is indicated by the RDY-LED on the
corresponding components flashing green/red and the Control Unit RDY-LED flashing
orange at 0.5 Hz.
Parameter p7827 indicates the progress.
The update has been completed if the RDY-LED on the Control Unit stops to flash at 0.5 Hz.
Once the update process has been completed, the RDY-LED of the respective component
goes into a steady light condition, for which the upgrade has been completed and the new
firmware has been activated. For the components for which the RDY LED flashes green/red
at 2 Hz you must perform a POWER ON to activate the new firmware.
Note
When activating the new firmware, it is possible that a component interrupts cyclic
communication. Communication problems will then occur that you must acknowledge.
For individual components, STARTER dialogs ("Drive Unit" -> "Configuration" -> "Version
Overview") can be used to read the firmware version or start a firmware upgrade manually
for specific components. The versions of the DRIVE-CLiQ components and that of the
Control Unit can also differ. Information can be found in the version overview.
Note
DRIVE-CLiQ components with higher firmware releases are downwards compatible and also
operate with DRIVE-CLiQ components that have lower firmware releases.
