Dear All,

How do I upload program from MP377 HMI.

Is it possible?

Or 

Do I have to have the original back up?

Regards

Satheesh

Hi,

Uploading only possible, if the Transfer of the current project file from the configuration computer to the operating unit must be performed using the Upload option "Enable backtransfer".

So if the option was set then yes, if not then no.
