The location of each dot is expressed by Cartesian coordinates: an X coordinate
(horizontal direction) and a Y coordinate (vertical direction). The coordinate ori-

The screens of the PT are classified and managed by screen numbers.
Screen numbers are used to designate the first screen displayed when the PT is
started up, and to designate the objective screen when switching the screen dis-
play, etc.
The PT allows up to 3999 screens to be registered, apart from those screens
reserved for specific functions. For these 3999 screens, screen numbers can be
designated without restriction within the range 1 to 3999. There are also no re-
strictions on the order of screen numbers, they can be discontinuous either.
When creating a screen at the PT with the Support Tool, designate a screen
number and then register the display elements.
The screens that can be displayed by the PT are classified as follows according
to their function.
• Normal (Standard) screens
• Overlapping screens
• Window screens
• System screens
Normal (Standard) screens are the basic screens of the PT. There are no specif-
ic functions themselves and their purpose is to display elements that have al-
ready been registered.
