Screen 2: - Screen 2 illustrates the activation of message texts by means of the
associated variable. A message text is also enlarged in the display. The screen
contains two message text elements. These are activated via the outputs Q1
and Q3 and appear in the display. The texts are only displayed if the
corresponding outputs are 1. No message is assigned to output status 0.
Screen 3 - Screen 3 illustrates the control of an enlarged message text element
containing two message texts that are assigned to the two states of output Q2.
Q2 = 0 a Message text: Q2 OFF
Q2 = 1 a Message text: Q2 ON

Screen 4 - Screen 4 is basically the same as screen 3 except that it also includes
the Visibility element. The message text can be made invisible via input I1. The
setting for this was made in the Visibility tab. Make contact bit logic is selected.
With break contact bit logic, the message text element is made visible when
actuating I1.

Screen 5 - Screen 5 is basically the same as screen 4 except that the Invisible
function has been replaced with Flash as the Display change function. When
input I2 = 1 (make contact bit logic), the message text can be made to flash.
