Appendix 1 Module Label

Module Label
Description
Values written to/read from a module label are reflected to the module in batch at the time of
refresh. This shortens program execution time.
Values written to/read from a module label are immediately reflected to the module. Although the
program execution time is longer than refresh, the responsiveness will be increased.
