To select the controllers to update:
In the tree, click one or more controllers.
All controllers of the same type are selected by default. If the controller software is already up-to-date, it is grayed out. To remove a controller from the selection, just click it.
Note! To force a controller to be updated, for example, if you want to down-level the software, press the Control key, then click the controller.
When you are ready to continue, click Next.
The Update summary window opens.
