Visualization with the

Screen 5:
Screen 5 shows an example using the Visibility tab. If I4 is
closed, the value entry element is made invisible. The N/O
contact bit logic is set. If N/C contact bit logic was set, this
would create a visible switch function. The element remains
operable even when invisible, and value entry is still
possible.

Screen 6:
Screen 6 shows an example using the Operability tab. The
same Visibility setting is used as in screen 5. Closing I3 will
disable the entry function (N/O contact bit logic). If the value
entry element is disabled, you can still select it (it flashes),
but Entry mode (change values) is disabled. If the value entry
element is in Entry mode when I3 is closed, the display
system switches automatically to Selection mode. If N/C
contact is set as bit logic, entry is only possible if I3 is
actuated. I4 switches the value entry element to invisible,
however, it still remains operable allowing values to be
changed.
