Take a look at the RA website about the "v6" PanelView Plus terminals. It's a new logic board and OS for the PV+ 700-1500 terminals that supports the newest PV+ 6.0 firmware and the FactoryTalk View Studio 6.0 editor.
I'm commissioning a bunch of PanelView Plus 1000's (eight of them) that came out of the factory with 5.10.00 and I've upgraded to a middle revision of 5.10.03 because I've found that to be the most stable with the combination of products I am using (ControlLogix 19.52 redundancy and ControlNet).
I am using FactoryTalk View Studio 6.0 and every time I build a runtime file, I need to change the target platform setting from 6.0 back to 5.10 before I download the *.MER file. It's worked perfectly.
You need to do like I'm doing; select version 5.10 when you create the runtime *.MER file, and it will run on your PanelView Plus 5.10 terminal.
