Panelview c600 question

Good day,
This is my first post on this helpful forum.

I am doing some work on a panelview c600 (ct6c)

I understand that one needs to go online with the HMI to do any editing or programming to the hmi.

I would like to know if there is a way to simmulate the program. I have downloaded from the HMI itself, no i am back in the workshop without the him and wanted to edit the screens.

My question is, can i run the backup i have here on my pc without having the hmi present. then upload when i get back to the him.

thanks

Just an update, i have found that if i use Pvc emulator software from Rockwell site, this enables me to do what i need to do on my hmi.
