General Operation
Using the Touch Panel screen, it is possible to observe the operating status of
the machine or system being monitored and, at the same time, to intervene di-
rectly in the process running simply by touching the buttons and input fields
displayed.
Operation of the Touch Panels TP27 and TP37 is intuitive to a large extent,
because
S operating elements can be positioned where they belong, from a functional
point of view,
S labeling of visible buttons is dynamic; in other words, labeling can be
changed online, according to the language required, or
language–independent bitmaps can be assigned to the buttons, for example,
S any sections of the system or process screen are rendered operable by su-
perimposing invisible buttons
S virtual keys for cursor functions and value input only appear when they can
actually be used: In input windows.
A screen occupies the entire display. An example of screen partitioning on the
TP37 display containing several open windows is illustrated in figure 3-1. The
TP27-6 has a smaller display, so that the operating elements are cascaded
(overlap).
