4.6.2.1.1 Format
The maximum number of digits to be displayed is set in the Number of Digits field. The number of decimal
places to be displayed from this is set using Digits After Decimal Point. These decimal places are "real" decimal
places only when a REAL variable is used. For integer variables, only one decimal point is displayed in the
appropriate place. The value is still a whole number. For a two digit decimal setting, 1725 on the controller is
displayed as 17.25 in the input field.
Depending on whether decimal places are displayed, the field width corresponds to the Number of Digits. It can
be displayed as one character wider if the decimal point is used.
Leading places can be filled with zeroes if the option Display Leading Zeros is selected. By default, leading
places are filled with spaces.
4.6.2.1.2 Position
Allows the precise placement (in pixels) of the output field by entering coordinates in the X and Y fields. When
the 'Object Properties' dialog box is opened, the current coordinates of the output field are indicated.
The output field can be more simply and conveniently positioned with the mouse by clicking and dragging it. The
exact position can be adapted to a grid (see also The Picture Editor).
4.6.2.1.3 Data Point
The process variable whose value is to be represented in the output field is connected in the Source input field.
The variable name can be directly entered or selected by clicking the Assign... button.
4.6.2.1.4 Status
Allows the connection of a process variable which influences the output field during runtime (see also Controlling
Fields with Status Variables).
