backup
•
Making a backup copy of the settings
•
Restoring the safe settings after unsuccessful changes
•
Securing or restoring the settings when changing the memory card
When commissioning is completed, the settings of the bus operator unit can be saved.
Later – e.g. after unauthorized changes or after inadvertent changes or deletions of
settings – these settings can simply be retrieved.
Data backup or restoration of data can take place at 2 different locations:
•
Locally, that is, on the memory card (RMA792) of the bus operator unit
•
On the second device, that is, on the memory card of a second bus operator unit
connected to the bus
Storage on a second device is especially practical when, for compatibility reasons, the
memory card of the bus operator unit must be replaced.
Data backup saves the following settings:
•
Device list including the device name, order and display format
•
Favorite pages with all datapoints
•
Names and order of favorite pages
•
Setting the display of fault status messages on the bus (refer to section 8.5 “Display
of bus fault status messages”)
All other settings (device address, language, etc.) will
not
be saved.
After successfully restoring all settings, the bus operator unit will be restarted.
The following status messages will be displayed, depending on the action performed:
Status messages
Description
---
Command has not yet been executed
Restored
The settings have been successfully restored
Saved
The settings have been successfully saved
Failed
An error occurred during data backup or data restoration
To avoid compatibility problems between the settings on the RMA792 memory card and
the RMZ792 bus operator unit, following rule must be observed:
The software version of the bus operator unit must be identical to or higher than
the software version with which the settings were saved.
