Rule on overlay display
• The "Overlay Screen" object allows to overlay the specified screen on the screen currently dis-
played in the DU or the F940GOT when 1) Bit Device becomes ON.
• Up to 3 screens can be overlaid including the one currently displayed. If overlay using a control
device is performed, any screen cannot be overlaid.
• All the objects arranged on overlaid screens are valid. Accordingly, when touch keys are overlaid,
for example, one on the overlaying screen (top screen) has the priority.
