(1) If the memory card is not supported, for example, KTP178 does not support uploading, it does not have a CF/MMC/SD memory card slot. If the memory card is not supported, only the "PROSAVE" can be used to backup and restore the touch screen. "Backup" is Refers to upload the running file in the panel memory to the computer. This file can only be downloaded to the same model panel and cannot be opened, viewed and edited. The "Restore" function is used to download the backup file to the panel.
(2) If the "Return" option is selected at the same time when the memory card is supported for downloading, such as the MP277 with a memory card, the following conditions are met:
First, the CF card must be inserted in the panel. The "Allow upload" function must be activated.
This allows the upload function to be performed. "Upload" refers to the transfer of the compressed original project file stored in the external memory of the panel to the computer. The file can be opened, viewed, and edited flexibly, or it can be used as a port between different panels.
