Some components or operators offer functions ("Operator Functions"). The FUNCTION Action is used to call a function on the specified component.
An Action may use a Value and an Address Value: optional function argument; refer to the documentation of the operator for more info. Address: the name of the operator and function, like "$operator.function".
Optional value for the function. If a value should be provided is documented for the component that you want to trigger a function on.
The address and name of the function to be triggered. The address should start with a $ (dollar sign). To find the right address, see the 'Functions' dialog of the component ("Functions Viewer").
Synchronous or asynchronous
This action is performed synchronously with data processing. If an action is asynchronous, it is performed only after all synchronous actions in a sequence have been called. A synchronous action is performed immediately.
