This string indicates that the module label is for the direct access. A module label without the string is for the auto refresh. The
following table shows the differences between the auto refresh and direct access.
Type Description
Auto refresh Values that are read from or written to the module label are reflected in
the module collectively at the auto refresh. The run time of the program
can be reduced. To use the auto refresh, set "Target" to "Module Label"
in "Refresh settings" of the module parameter.
Direct access Values that are read from or written to the module label is reflected in
the module instantly. Compared with the auto refresh, the run time of
the program becomes longer. However, the responsiveness is high.
