Example program 1 – Associated variable and visibility
The program consists of five screens that you can select via
cursor buttons
Í
and
Ú
. The screen change was defined in
the button editor (
a
section “Button editor”, page 317).
The screens show examples of the use of the associated
variable and the visibility function.
The circuit diagram uses six on-delayed timing relays that
activate outputs Q1 to Q4, as well as LED 3 in succession
after the elapsed time. The process is carried out in a
continuous loop since the timing relay T06 resets all timing
relays after the set time.

Screen 1
Screen 1 illustrates the activation of the bit display soley
using the associated variable. The first screen shows four bit
display elements. These are triggered in succession via the
Boolean operands Q1 to Q4. N/O contact is selected as the
bit logic by which the bit display elements assume the status
of the corresponding outputs (on/off).

h
The bit display is always output as a solid covering
element. It is only possible to make it invisible. When they
are positioned overlapping each other, the first bit display
will be arranged at the back and the last bit display will be
positioned at the front. This arrangement can be modified
for the activated screen element in the menu bar
(Foreground/background).
h Large area bit displays require a high level of processing
capacity and should therefore be avoided in applications
where the runtime is critical.
