Accepting initial values
If you accept the initial values, then all of the actual values of a data block are overwritten. If you hadn't selected
an initial value for a variable, then the Programming Tool PLC828 sets it to zero/OFF. Other data blocks are not
changed in the process.
In order to reset all actual values in the actual data block to the initial values:
In the table, click on the right mouse button and in the context menu select "Accept initial values".
or
Select the menu command "Edit" > "Accept initial values".
Loading and saving the data blocks
Save involves writing the DB (depending on the selection, structure + initial values + additional blocks and tables
or actual values or both together) from the PC work memory to the hard disk or to another external storage
medium. After the project has been opened, these values are again available.
Load into CPU involves writing the DB (depending on the selection, structure + initial values + additional blocks
and tables or actual values or both together) from the PC work memory into the PLC828.
Load from CPU is the inverse operation.
Load operations are selected from the data class perspective.
