Question

Is there a command that can write 100 words of data at once from a computer to the DM Area in the CPU Unit?

Answer

Yes, a FINS (Factory Interface Network Service) command is supported for CS1-series and CVM1/CV-series Programmable Controllers. 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 Programmable Controllers, 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.
