Example program 1 – associated variable and visibility
The program consists of five screens that can be selected with
the Cursor buttons
Í
and
Ú
. The screen change was defined
in the Button Editor (
J
Section “Button editor”, Page 331).
The screens show examples of the use of both
associated
variable
and visibility elements.
The circuit diagram uses six on-delayed timing relays that
activate outputs Q1 to Q4 and LED 3 in succession after an
elapsed time. This operation is run in a continuous loop since
timing relay T06 resets all timing relays after a set time.

Program:
Bit_Display_01
Screen 1
Screen 1 illustrates the activation of the bit display exclusively
via the associated variable. The first screen contains four bit
display elements. These are activated in succession via
Boolean operands Q1 to Q4. A make contact bit logic is
selected for setting the bit display elements to the state of the
corresponding outputs (on/off).

Screen 2
Screen 2 illustrates the activation of the bit display with
overlaid static text, exclusively via the associated variable.
Screen 2 contains four bit display elements. These are
activated in succession via Boolean operands Q1 to Q4. A
make contact bit logic is selected for setting the bit display
elements to the state of the corresponding outputs (on/off).
The bit display is overlaid partly with static texts.
