When the [Plate Color] is set to transparent, a
Data Display and a Message Display will be placed on the front
layer and displayed overtop other objects. Too many objects in the
front layer may reduce the speed of the display's redrawing
speed.

21.9 About the
Layer Separator
The transparent feature of the plate color on
Window screens cannot be set to ST3000 and GP3200 series models. If
it is set up, a warning appears when you save a project. If the
project is run on the display unit, the plate color will not be
filled.
