Unit Switch

Working with different units of measurement is a common challenge in industrial control systems. There are many reasons why unit conversions are necessary, but a key factor is localization: different countries use different measurement systems.

This is you HELIO lets you define unit conversions using the Project Settings, where you can define several conversions between source and target units.

In addition to international standards, you often want to change numerical values within a system, such as converting grams to milligrams, to better recognize subtle differences in product weight.

The Unit Switch makes it easy to switch between multiple units seamlessly without having to go back and forth on the calculator.

Properties​

Container​

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

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.

Description

Will be displayed underneath the element. This description provides additional guidance or instructions for operators manipulating the element. It expands on the label by offering supporting details and clarifying what the element represents or how it behaves. It provides an opportunity to offer more detailed context regarding the potential impact of changes or further instructions on the desired input format.

Allow Converting​

Source unit

Select the source unit to indicate the original unit of measurement from which values will be calculated.

  • Based on the unit conversions you have defined in the central project setting, HELIO will display the appropriate switch for this unit.
  • Each Unit Switch can only convert one unit, but feel free to use as many switches as you need.

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.
