Yep. When switching it to V2 in uniapps it will just detect the the version is not the same as the project on the next download. You can select to overwrite it or not but the path you show above Joe is how to set the project to V2 thus it will stay that way.  I found it and went to post it here but you beat me to it. Â
On a related manner with the same behavior, you can find screen saver settings for the project in the solution explorer, Hardware config/ Controller Model. You can also set these in uniapps but then it won't match the project on the next download. Â
I have had this issue right from the start with UniLogic...on multiple PC's and laptops. Even with VisiLogic, but there I can check the "transparent background" check box to easily eliminate it.
In UniLogic, I set the background fill to transparent and it does nothing. I was just putting up with it up until now, but it would be nice to get to the bottom of it.Â
As for image programs, I think all I have is what ever comes standard with Windows, but I'll double check that this weekend. Currently, I am running Windows 10
Found it. In Uniapps in bottom Network tab then Modbus then top Debug tab there is a button:
Turn Legacy OFF
and a notice:
After changes please reboot the PLC
