Hi :-)
Well, I can give you half of this one :-/

How can I have multiple instances of VisiLogic running at a single time?
To have multiple instances of VisiLogic:
1.Copy the folder "Unitronics VisiLogic_C" from "C:\Program Files\Unitronics"
2.Paste that copied folder somewhere else on your hard drive.
3.You can then open up the file "VisiLogic.exe" from "Unitronics VisiLogic_C\Main"
inside each separately pasted folders.
(The typical limitation is that only a single "VisiLogic.exe"
can be opened at a time, but having a copied folder "tricks" and allows this)
This will also let you, of course, look at a copy of the same app, and view both the HMI and Ladder app.
I haven't heard of plans for a 5.7" format PLC with a 640x480 screen resolution, but I will check.
If I have news about the other issues, I will share it :-)
