Screen 4:
Screen 4 is essentially the same as screen 3 but also has an
additional visibility element. Input I1 switches the message
text invisible. The setting for this is carried out in the
Visibility tab. N/O contact bit logic is selected. If N/C contact
is set as bit logic, the message text element is visible if I1 is
actuated.
