I am very new to S7 PLC programming (S7 Simatic Manager v5.5) and I wanted to know how to back-up a system consisting of multiple PLC Stations (S7-1200, S7-300, etc). I am able to upload station to PG but that will save only per station. How about saving the whole system? I am not sure if i am using the right terminology. As you can see, I was given a zip file for the S7 project and it contains the whole system. I am trying to see how the commissioning engineer was able to do it (don't ask why I am not asking him instead). How can I then use this project file to download the program to the PLC/system once I decide to restore. I am at loss and have been searching for references over the internet. Uploading and downloading per station is no problem. I cannot seem to know how to do it on multiple stations system.
I hope I have made some clear question or somehow you have managed to understand it.
