The PLCDataBackup allows you to save data states of a Siemens PLC on a PC. If necessary, you can write the data backup back to the PLC at the push of a button. The best thing about it: You do not have to adapt your PLC program for this.
You can create the backups either manually or automatically at specific times. Setup is quick and easy. Please note that only data is written to the PLC. The structure of the data blocks is not adapted. Therefore, the data blocks whose data are to be restored must have exactly the same structure as the backup.
