value range (9999). The value of QV will therefore jump to 9999 when the
entered value is 10.00 and I1 is actuated.

Screen 4 - Screen 4 shows an example of the Number range/format tab,
particularly the Scaling range area and Input format area r Fixed step width.
You can enter any value from 0.00 to 10.00 in step widths of 0.50 (fixed step
width). After I1 closes, the preset actual value SV is transferred. When
transferred, the actual value QV switches to the SV value entered and
continues counting from this value. The maximum scaling range (10.00) is
assigned to the maximum value range (9999). The value of QV will therefore
jump to 9999 when the entered value is 10.00 and I1 is actuated.

Screen 5 - Screen 5 shows an example of the Visibility tab. If I4 is closed, the
value entry element is made invisible. The make contact bit logic is set. When
using break contact bit logic, this is the same as a “visible circuit”. Even when
invisible the element is operable and value entry is still possible.

Screen 6 - Screen 6 shows an example of the Operability tab. (visibility set as in
screen 5.) When I3 closes, the entry function is disabled. Make contact bit logic
is selected. If the value entry element is disabled, you can still select it (flashing)
but Entry mode (changing values) is disabled. If the value entry element is in
Entry mode when I3 closes, the Pico GFX-70 automatically switches to
Selection mode. When using break contact bit logic, entry is only possible if I3
is actuated. The value entry element is made invisible via I4. However, it is still
operable and values can still be modified.
