The Scaling Active option must be selected for this input field to use scaling. This activates the two following
options.
The permissible value range of the variable is determined in the control application using PLC Value Range. No
values outside of this range can be input in the visualization application. If a variable is entered which falls
outside of this range, then it is automatically corrected to the nearest permissible value. The user is notified and
and can confirm the change.
If the Parameters from PLC option is checked, then variables can be connected and used as upper and lower
limits of the PLC value range. This allows the scaling range to be changed by the controller during runtime.
Scaled Value Range sets the appropriate value range for value display and input. When this value is input,
decimal places might possibly have to be entered as well. Automatic decimal input only has an effect on Visual
Components during runtime. It does not have an effect on the editor.
Variables for the upper and lower limits of the value range can also be connected for this area by selecting the
'Parameters from PLC' option.
A variable can also be connected here which allows the decimal point to be shifted during runtime. However,
this option is only active if decimal places are defined for the field.

Introduction to Visual Components 2.3
A text can be defined for each input field which is displayed when the editor is in Simulation mode. In this way,
pictures containing practical values in the input fields can be created for documentation .
