step 7 online-offline

Hello,

When I go online with step 7, Is there no risk of overwriting the program in the PLC if the Offline is different ?

Thanks

You are at great risk of losing the program. You should always make a backup copy of the program first before tinkering around in there. If you are not familiar with these best practices, you might want to get more training before downtime occurs.
