Start NS Designer,
From menu Settings(S) select System Settings(R)
and check Inital tab. You can map System Memory to PLC.
It comes with lots of options - see System Memory List (Y).
Kinda lost on it, all I see is strobe screen. All I want to do is switch screen on bit true from plc, or bit out. And why is everthing coming from a "DM" and not a bit reference. I thought DM was to store data and not just a simple "bit on/off".
