Appendix 1 Module Label
Description
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 "Module
Parameter".
Values that are read from or written to the module label are
reflected in the module instantly. Compared with the auto refresh,
the run time of the program becomes longer. However, the
responsiveness is high.
