An application can be selected for download by activating its preceding checkbox.
Multiple applications may be selected, even if they won't be downloaded to the same
device. By default either all applications or the applications last time selected are
activated.
In case that an application selected for download is differing from an previous version
that has already been downloaded to the PLC before, you may choose among the
following options:
• Try to perform an online change. If this is not possible, perform a full download. By
default this option is selected. So the modified parts of the selected applications
will be changed on the PLC and only the newly created parts of the selected
applications will be downloaded to the PLC.
• Force an online change. If this is not possible, cancel the operation. If an online
change for (at least one of) the selected applications is not possible (for example if
the command 'Clean all' or 'Clean Application' had been performed before), the
download will not be executed.
• Perform a full download. Regardless the versions already existing on the PLC all
parts of the selected applications will be reloaded to the PLC.
For applications that are not yet present on the PLC a full download will be carried out
automatically.
In addition you may decide (by activating the corresponding checkbox)
• whether old applications that are no longer part of the project should be deleted
on the PLC
• whether the selected applications should get started after the download has been
performed
