Screen 2
Screen 2 illustrates the activation of the bit display with
superimposed static text, exclusively using the associated
variable. The second 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). The bit display is partly covered by the static
texts.

Screen 3
Screen 3 illustrates the options of the Visibility tab of the bit
display. This screen contains a bit display element that was
enlarged to the size of the entire screen. The activation is
implemented with the Boolean operand Q1 with the N/O
contact bit logic, by which the bit display element takes on
the status of output Q1 (on/off).
The bit display is switched invisible via the Boolean operand
Q3. The bit logic here is also set to N/O contact, the bit
display is therefore invisible as long as Q3 is On. During the
Reset pulse only the frame of the bit display is visible (the bit
display status is Off, bit display is visible). The display is
partly covered by static texts.
