Hello,

After fine tuning procedure I upload data from PLC to TIA project.
so in the project I have the data of the last built machine.
If I make some updtate to the project and I load it to a machine
built some time ago,the original tuning data will be overwritten
by the data of the last machine.
How can I save the original data of the machine and restore them

Best Regards,

Pier Giovanni

Hello,

I will try the suggestion.

I do not change TIA version, but some instructions in the project to update some functions  and to upload it into a machine built vith an earlier version.
