HE: Numeric Box

Numeric Box

A Numeric Box enables you to:

Show any numeric value within a Display.
Enable a single Touch Element to trigger multiple events. Multiple bits can be linked to one element, triggering Load screen, set, reset, and toggle bits, and more.
Control the format in which that value is shown, including the placement of a decimal point and leading zeros.
Use Linearization to show a converted value, such as an analog temperature converted to degrees Celsius.
Enable a user to securely hide numeric input values , by checking the Mask Entry property.
Enable a user to edit or enter a number via the panel’s virtual keyboard, by unchecking the Read-Only property.
Use Ranges to enable background and foreground colors to change dynamically based on the value of the linked tag.

Numeric Box Attributes

Numeric Value

The value of this tag determines what is displayed in the HMI element.

Read-Only

Read-only is checked by default. To enable the end-user to enter data, you must uncheck Read-only.

Tag: Data Entry Complete

The linked bit turns ON when an element has been touched, the keypad has opened for data entry, and the user presses OK. The bit turns ON whether or not any data has actually been entered. Note that the bit remains ON until it is reset.

Tag: Enable
Data Entry

Assign a bit to allow you to enable or disable data entry.

Tag: Minimum Value

This contains the minimum permitted value. The value may be provided by a tag or a constant.

Tag: Maximum Value

This contains the maximum permitted value. The value may be provided by a tag or a constant.

Mask Entry

To enable the end-user to securely hide numeric inputs, check the Mask Entry. When it's checked, the number of '*' matches the length of the numeric value, including the sign.

Ranges

Defines a set of ranges for the numeric box.
When none of the ranges match, the default background and Text Font foreground will be used.

Text Before

Enter any text you wish to set as a prefix to the numeral. You can also include special characters, such as a degree sign, by clicking the button on the right of the Text Before field.

Text After

Enter any text you wish to set as a postscript / postfix to the numeral. You can also include special characters, such as a degree sign, by clicking the button on the right of the Text After field.

Numeric Box Linearization

Linearization

When checked, the linearization option applies a linear transformation to numeric values.

Note that the value entered by the user is not directly stored in memory. Instead, the stored value corresponds to the input X required to achieve the specified output Y based on the linearization parameters.

Lin. X Min

This contains the minimum input value. The value may be provided by a tag or a constant.

Lin. X Max

This contains the maximum input value. The value may be provided by a tag or a constant.

Lin. Y Min

This contains the minimum output value. The value may be provided by a tag or a constant.

Lin. Y Max

This contains the maximum output value. The value may be provided by a tag or a constant.
