In this manual, “download” refers to transferring data from the Sysmac Studio to the physical Controller
and “upload” refers to transferring data from the physical Controller to the Sysmac Studio.
For the Sysmac Studio, synchronization is used to both upload and download data. Here, “synchronize”
means to automatically compare the data for the Sysmac Studio on the computer with the data in the
physical Controller and transfer the data in the direction that is specified by the user.
