When users don’t have easy access to a laptop nor PC nearby the installation or the machine, is difficult to face the task of making some modification or backups by downloading/uploading the PLC program.

For this purpose, there’s a way to download/upload the PLC program directly from/to a USB memory stick through the DOP HMI.
