Introduction to <strong>Visual</strong> <strong>Components</strong> 2.3<br />

Assign...<br />

100% Value<br />

100% Source<br />

Assign...<br />

This variable can accept values like those defined under 0% Value.<br />

The Assign... button opens a dialog box to select a variable for the 0% Source field. By default,<br />

only variables of suitable types are displayed.<br />

Specifies the upper limit of the allowed value range for the process variable on the control<br />

panel.<br />

Possible Settings Possible settings are limited by the input field width in<br />

characters so that limits can be entered and represented in the<br />

input field.<br />

In addition, input is limited by the connected variable data type<br />

as follows.<br />

USINT SINT<br />

INT UINT<br />

Value range from −99999 to 99999 (limited by<br />

the maximum input field width to 5 characters).<br />

DINT Value range from −2147483648 to 2147483647<br />

UDINT Value range from 0 to 4294967295<br />

REAL Value range from −9999999999 to 9999999999<br />

These specifications apply when no decimal places are set. If<br />

decimal places are used, the specification refers to the units in<br />

the selected definition.<br />

Example:<br />

A SINT variable can be scaled from −999.99 to +999.99 when 2<br />

decimal places are set.<br />

In this way, invalid input is automatically corrected to valid data.<br />

Determines the process variable which contains the upper limit of the value range for the<br />

variable processed with this input field on the control panel during runtime. This setting is only<br />

available if Parameters from PLC is selected.<br />

Possible Settings Depending on the data type of the variable connected to the input field,<br />

variables with the following data types can be connected:<br />

USINT SINT Variables of data types USINT, SINT, INT, UINT, or DINT<br />

INT UINT DINT can be used independent of the data point of the<br />

connected variable.<br />

UDINT UDINT<br />

REAL REAL<br />

(The data type has to be able to accept the desired limits<br />

during runtime!)<br />

This variable can accept values like those defined under 100% Value.<br />

The Assign... button opens a dialog box to select a variable for the 100% Source field. By<br />

default, only variables of suitable types are displayed.<br />

Shift Decimal Point<br />

Using this setting, the decimal point in the output field can be moved during runtime using a variable from the<br />

control application.<br />

This setting is only available if Scaling Active is selected under this tab and at least 1 decimal place is specified<br />

in the Digits after Decimal Point field under the Parameter tab (otherwise, there is no space set aside for the<br />

decimal point).<br />

Source Determines the process variable which contains the number of additional decimal places to be<br />

displayed. If fewer decimal places should be displayed, then the value of the variable has to be<br />
