Providing Options Using Enumerations

Another way to guide operators is to let them choose between distinct options. In HELIO this is done using Enumerations.

Via the Data Tab

1. Create a string or numeric variable

• Navigate to the Data View.
• If you haven't already done so, create a variable of the following types: Numeric Data Variables or String.

2. Add possible options using enumerations

• Locate the Enumeration group and activate it for this variable.
• Add possible values for this variable and provide a label for each state.
• These labels will be used in the HMI, for example if you want to display a dropdown for setting the machine's state.

3. Using enumerations to provide options to Operators

1. Add Magic Input element to your project.

2. Link its Value property to the variable you just defined.

3. Use the Control type property to determine how these options are provided to operators.
