15.13 Monitoring and modifying values in the CPU

Copying the snapshot values to the CPU

To copy the snapshot values to the actual values of the data block tags in the CPU, click the

following button:

The online CPU loads the snapshot values into the actual values. The Monitor value column

shows the actual values in the CPU. The scan cycle might subsequently change the values

in the CPU from the snapshot values, but at the time you make the copy, the CPU loads the

snapshot values in a consistent download.

Be aware that if your snapshot contains state information, timer values, or calculated

information, the CPU restores those values as of the time you made the snapshot.

Copying the snapshot values to the start values

To copy the snapshot values to the start values of the data block tags, click the following

After you compile the DB and download it to the CPU, the DB uses the new start values

when the CPU goes to RUN mode.

Copying individual snapshot or monitor values to start values

The data block editor also lets you copy individual values and paste them over start values.

Simply right-click a value in any value column and select Copy to place it in the Windows

clipboard. Then, you can right-click on any start value and select paste to replace that value

with the value in the clipboard.

After you compile the DB and download it to the CPU, the DB uses the new start values

when the CPU goes to RUN mode.
