Alarm
Sends information about the detector model instance and the event that triggered the action to a specified asset property in ITSW. You must use expressions for all parameters in `IotSiteWiseAction`. The expressions accept literals, operators, functions, references, and substitutions templates. Examples
For literal values, the expressions must contain single quotes. For example, the value for the
`propertyAlias`parameter can be`'/company/windfarm/3/turbine/7/temperature'`.For references, you must specify either variables or input values. For example, the value for the
`assetId`parameter can be`$input.TurbineInput.assetId1`.For a substitution template, you must use
`${}`, and the template must be in single quotes. A substitution template can also contain a combination of literals, operators, functions, references, and substitution templates. In the following example, the value for the`propertyAlias`parameter uses a substitution template.`'company/windfarm/${$input.TemperatureInput.sensorData.windfarmID}/turbine/ ${$input.TemperatureInput.sensorData.turbineID}/temperature'`You must specify either`propertyAlias`or both`assetId`and`propertyId`to identify the target asset property in ITSW. For more information, see Expressions in the Developer Guide.
