3. On the toolbar, click "Snapshot of the monitor values".
The actual monitor values are applied in the "Snapshot" column. Note here that the
monitor values can originate from various program cycles.
The following options exist to apply the actual values from the snapshot as start value in the
offline version of the data block.
