When the input is confirmed, the input numeric value is stored to a numeral
memory table. Then, the occurrence of a change in the contents of the nu-
meral memory table is notified to the host via the PT status notify area (page
55).
S 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 nor notification to the host is
executed.
S When NT30/620 compatible mode is being used, the current screen number
occupies the first word of the PT status notify area and the words containing the
updated memory table number and PT status notify bits are shifted down one
word. (Refer to page 441.)
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 where the input numeric value is written are displayed.
Cursor Frame
If a Cursor frame is set for the numeral setting input field, the frame that encloses
the input field is displayed while the field is accepting input.
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.
