I would say no, you can not export a screen from a DP200 to a DP570, because the DP570 uses the Vector based screen editor (Show screen function) where the DP200 uses the classic (Define area/Define Screen functions).
But the export/import actually seems fairly straight forward, just open the left side panel (Project manager) and look for the screen definitions folder. Right clicking this will show the option to export or import definitions.
I hope this clarifies a few things for you
