Published Action defines the signature of an Action as a combination of ActionRequest and ActionResponse messages and a list of targets with an optional mapping to OPC UA Methods.
The Action targets, ActionRequest and ActionResponse information is the input to the ActionMetaData.
The parameter RequestDataSetMetaData defines the content of the ActionRequest.
The DataSetMetaData parameter of the PublishedDataSet defines the content of the ActionResponse.
The parameter ActionTargets provides a list of Action targets with the same signatures that can be executed based on the published Action definition.
