Translation Keys with Values (Data Variable Type)

Just like the Translation Key (Data Variable Type), this type lets your data source send a Translation Key. However, it also lets the PLC inject dynamic values into your translations using placeholders.

This enables messages like "Temperature 99 is too high" where the temperature value changes based on real-time data.

JSON Format​

The data source must provide a string variable containing a JSON object:

{
  pattern: 'Status.TemperatureTooHigh',
  arguments: { temp: 99 }
}
  • pattern: The Translation Key to use.
  • arguments: An object containing one or more values to inject into the translation.

How It Works​

Your data source sends a JSON string containing the Translation Key and the dynamic values to inject. HELIO looks up the translation, replaces placeholders with your values, and displays the result in the current language.
