Magic Input

About​

Examples of Magic Inputs linked to variables with different data types.

The Magic Input can be a real time-saver when you're creating pages that manipulate data from your PLC. It automatically adapts to the Data Variable Types of the variable you're linking to and provides operators with a UI component that fits best.

The Magic Input simplifies the creation of HMIs that modify data variables from sources such as your PLC. HELIO automatically adapts to the of the variables being linked and presents a UI component that best fits the shape of your data.

For example, if an imported variable from your PLC is typed as Integer, the Magic Input component will display a Numeric Stepper.

Validations​

The Magic Input not only considers the data type, but also other features of data variables in order to validate all data entered by operators.

For example, Minimum and Maximum Values and

Enumerations

help prevent operators from inputting values that the machine can't handle.

Do Not Rely Solely on Client-Side Validation!

Client-side validation greatly improves the user experience for operators. However, your backend, e.g. your PLC should still reject invalid values. You should never rely solely on client-side validation of input data.

Properties​

General

Label

Provides context and information to operators, guiding them and helping them understand the value of this particular element. A good label instills confidence in operators when making adjustments.

Icon

This icon will be displayed next to the element's label on pages that support it, like the Dashboard Page. An Element can make use of the icon to:

  • Provide more context to add meaning
  • Improve recognition and discoverability, especially on larger pages

Value

The current value that should get updated when an operator manipulates the input, usually this will be bound to a Data Variable.

Is disabled

Use this property to disable the element in certain situations, such as when your PLC is in a state where manipulation should not be possible.

Is invalid

Use this property to indicate that the current value of the element is not acceptable.
Appearance
Display Condition

Condition

Determines whether an element or page should be visible or hidden to the current user. The condition can be set to different types of Dynamic Property – as long as the the type returns true or false you're good to go.
