3. Press the ENT key of the input key – control or the key to confirm the input.
When the input is confirmed, the input numeric value is stored to a numeral
memory table entry. Then, the occurrence of a change in the contents of the
numeral memory table entry is notified to the host via the PT status notify
area (page 61).
Reference: When a numeric value is confirmed the PT checks whether the value falls with-
in the specified upper and lower limit values. If the numeric value is outside the
specified range, the buzzer sounds three times, the input numeric value is
canceled, and the screen returns to the display before starting the input. In this
case, neither writing to a numeral memory table entry nor notification to the
host is executed.
When NT20S or NT30/620 compatible mode is being used, the current screen
number occupies the first word of the PT status notify area and the words con-
taining the updated memory table entry number and PT status notify bits are
shifted down one word. (Refer to page 451.)
Inputting Operation Using Touch Switches
A numeric value can be input in the same manner as when using an electronic
calculator by using the touch switch input key – control.
Initial Display
When a numeral setting input field is displayed, the contents of a numeral
memory table entry where the input numeric value is written are displayed.

Inputting an Integer Part and a Decimal Fraction Part
In the integer part, numerals are input from the lowest digit position and the input
value is shifted to the left as new numerals are input. If the input value exceeds
the number of display digits of the integer part, the numeral at the highest digit
position is cleared.
After the input of a decimal point, the succeeding numeric input is regarded as a
decimal fraction. In the decimal fraction part, the numeral input first is displayed
in the first place. After that the input numerals are displayed to the right of the
preceding input. If the input value exceeds the display range, the numeral occu-
pying the first position to the right of the decimal point is cleared.
