Bit Display Example Program 1 – Associated Variable and Visibility
The program consists of five screens that can be selected with the up and
down cursor buttons. The screen change was defined in the Button Editor (see
Button Editor on page 5-37).
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.

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.

Screen 3 - Screen 3 illustrates the possible uses of the Visibility tab for the bit
display. In this screen a bit display element has been enlarged to the full size of
the screen. It is activated via the Boolean operand Q1, with a make contact bit
logic so that the bit display element takes on the state of the output Q1
(on/off).
