Backup and restore options
You will make a number of changes to your automation system over time, for example, add
new devices, replace existing devices or adapt the user program. If these changes were to
result in undesirable behavior, you can restore the automation plant to an earlier version if
you have a backup. STEP 7 and the S7-1200 CPU offer different options for backing up and
restoring the hardware configuration and software.
