you cannot do plug&Play with Profibus FMS devices, as part of the configuration is not available on the device.

You must have the original backup. Even if the Settings on the device are not exactly the same as in the backup, just use the backup and open the device only and save the device at the end of the process. After that you can make the necessary changes and download again.

if you don't have the even an old backup, contact customercare. I don't know if you can transform variants in real devices, and if there are, you must know what you are doing

hi

if you are not experienced, I recommend you dont download anything. Siprotecs are protection devices and only trained engineers or technicians  should operate them. you should attend a Training or contact an experienced colleague

on running Siprotecs you should compare the Parameters first, to check the differences. If the only differences are the ones you really wanna Change, then dowlnoad the Settings. On the Manual you will find Information about it
