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.
