Restore program from VDF file

[PeterFukt]

Hi,

I made many changes in a program today and created a project file for the customer to download it with Unidownloader.

But after I saved it, I noticed that the project file saved itself with the same filename as the original program, including the .vlp format. So now I have a project file but no Visilogic program file.

Is there anyway I can get the program back using the .vdf file or is the program code including half a day of work lost?

Hi,

You can try the following:

• Open UniDowload Designer
• Link the VDF file.
• Select the checkbox "Download data for Upload"
• Create UDC and download it to the PLC using UniDownloader
• Then using VisiLogic select to upload the project.
