7-4 CHAPTER 7 DISPLAYING AND INPUTTING DATA
Property Description
Fractional
Digits When the Display Type is 32-bit Floating Point, this property specifies the number of fractional digits
to be displayed.
When the Display Type is not 32-bit Floating Point, this property specifies not only the number of
fractional digits to be displayed but also the number of least significant digits to be displayed as the
fractional part. With this feature, an integer can be shown and entered as a fixed point number. When
the Fractional Digits is nonzero, say N, the entered value will be converted to an integer according to
the following formula before being output.
OutputValue = EnteredValue * (Nth power of 10)

Note: This property applies to the display of the initial value, the allowable minimum, and the
allowable maximum on the numeric keypad.
Alignment The alignment of the displayed value. There are three types of alignment: Left, Center, and Right.

Option Description
Pop-up Keypad You can bring up the keypad by pressing the numeric entry and enter
a value with the keypad.
On-screen Keypad
and/or Function Keys You can move the cursor by using the function buttons with the
operation of Select Next Data Entry Object or Select Previous Data
Entry Object to select the numeric entry. If there is an on-screen
keypad you can enter a value for the numeric entry right away. You
can also use the function buttons with the operation of Increase Value
By One or Decrease Value By One to change the value of the
destination variable.
當使用常駐式固定鍵盤時，在未按到想要輸入的元件時候是不能輸入的，此時如果直接輸入數值則鍵盤
輸入是無效的，也就是說剛一進入這畫面時，觸控屏系統並不會馬上將第一個數值輸入物件啟用的。客
戶須要先按一下該輸入物件後才啟用固定鍵盤按鈕，也才能使用鍵盤，否則鍵盤是無效的。
