This data can be transferred from the DB to the IP 240 and must be adapted in the DB beforehand.
If you wish to read the current values in the appropriate data areas, you must call the control FB and
parameterize Read function 1 or 3.
This data is specified by the parameters assigned to the configuring FB or is transferred from the IP 240
to the DB when the module is configured.
These data words are used internally, and may not be modified.
