Assign...
processed with this input field on the PLC during runtime. This setting is only available if
Parameters from PLC is selected.
Possible Settings Name of a variable with the same data type as the variable connected to
the input field. This variable can accept values like those defined under
100% Value.
The Assign... button opens a dialog box to select a variable for the 100% Source field. By
default, only variables of suitable types are displayed.
Scaled Value Range
Specifies the acceptable value range for the input and display in the visualization unit. During display, this
range is scaled to the process variable range set under PLC Value Range.
Parameters
from PLC
0% Value
This field determines whether a 0% value and a 100% value are input in the editor (box
unchecked) or if a process variable should be selected during runtime (box checked).
The dialog box displays the necessary configuration fields which correspond to this setting.
Specifies the lower limit of the permitted 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
Value range from −99999 to 99999 (limited by
the maximum input field width to 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
decimal places are set.
In this way, invalid input is automatically corrected to valid data.
0% Source 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 Depending on the data type of the variable connected to the input field,
variables with the following data types can be connected:
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
