Snapshot of the monitor values

Backing up actual values of all data blocks
With the option "Snapshot of the monitor values" you overwrite the start values of tags in the
offline version of a data block with actual values from the CPU. In this way, you can restore
the backed up status of the data blocks at a later date after changing the actual values.
To apply the actual values, you first generate a snapshot of tag values from the online
program. You can then apply these as start values.
Note
Note that the values from the snapshot are always copied. STEP 7 does not hereby check
whether all values originate from the same cycle.
