INT UINT the maximum input field width of 5 characters).
DINT Value range from −2147483648 to 2147483647
UDINT Value range from 0 to 4294967295
REAL Value range from −9999999999 to 9999999999
These specifications apply when no decimal places are set. If
decimal places are used, the specification refers to the units in
the selected definition.
Example:
A SINT variable can be scaled from −999.99 to +999.99 when 2
set decimal places are used.
In this way, invalid input is automatically corrected to valid data.
Defines the process variable which contains the lower limit of the value range for the variable
processed with this input field on the control panel during runtime. This setting is only available
if Parameters from PLC is selected.
Possible Settings Variables with the following data types can be connected to this property
depending on the data type of the variable connected to the input field.
USINT SINT Variables of data types USINT, SINT, INT, UINT, or DINT
INT UINT DINT can be used independent of the data point of the
connected variable.
UDINT UDINT
REAL REAL
(The data type has to be able to accept the desired limits
during runtime!)
This variable can accept values like those defined under 0% Value.
The Assign... button opens a dialog box to select a variable for the 0% Source field. By default,
only variables of suitable types are displayed.
Specifies the upper limit of the allowed value range for the process variable on the control
panel.
Possible Settings Possible settings are limited by the input field width in
characters so that limits can be entered and represented in the
input field.
In addition, input is limited by the connected variable data type
as follows.
USINT SINT
INT UINT
