Control of multiple drives 55

Graph data
The data for the graph format in the Home view is stored in the control panel only for
the selected drive. Upon changing the selected drive, any stored graph data is
discarded, and graph data collection begins for the new drive.
History graphs and all related settings (signal selection, horizontal timescale) are
saved in the drive, and the
History graphs menu shows always the graphs for the
currently selected drive. Data collection takes places independently in each drive.

Backups
The control panel can store backups from different drives. Conversely, backups from
a drive can be uploaded to another drive.

Customized content
Each drive in the panel bus has its own custom content because all the
customizations are stored in the drive.

Assistants
Assistants are drive-specific, which means that different drives in the panel bus can
have different assistants. However, the assistant framework is the same for all
assistants in all drives.
Faults and warnings with multiple drives

Faults and warnings in the currently selected drive
Faults and warnings in the currently selected drive are shown as normal.

Faults and warnings in other drives
Faults in the other drives in the panel bus appear
as remote faults.
Faults that require a restart look like any other
remote faults. They are shown normally if you
switch to the drive in which the fault has
occurred.
In the Fault view, the keys have the following
functions:
• Press ( Hide ), to go back to the previous view. The fault view does not
reappear as with regular faults.
• Press ( Switch ,) to connect to the faulted drive.
Only active warnings in the selected drive are shown in the control panel. To view
warnings in another drive, you must select that drive in the
Select drive menu.
