Data Variable (Dynamic Property)

About​

Include dynamic data from Data Source Types such as your PLC Connection into your current page or element. HELIO will display the value of the variable you choose.

Before including values of data variables, you need to define them using the Data View.

HELIO displays either placeholder values or live data from sources, depending on the Data Modes of the HMI Preview Panel.

HELIO will also remind you if you haven't properly linked a variable, yet.
