Is There A Command That Can Write 100 Words Of Data At Once From A Computer To The DM Area In The CPU Unit?

Yes, a FINS (Factory Interface Network Service) command is supported for CS1-series and CVM1/CV-series PLCs. This command is used to write 100 words of data all at one time.

However, only the CS1-series and CVM1/CV-series support this command. When using C-series PLCs, the data must be written 4 times, writing 30 words each time.

Therefore 100 words of data cannot be written simultaneously when using C-Series.
