    <p>Defines the OPC UA events that will be subscribed from the server.</p>
	<p>The Source node defines the node where events are subscribed for. 
       The root Server node id is used, if all events of the server shall be processed. 
       If available, other specific node ids can be used for a subset of events.
       Not using the root Server node might for example make sense in case of an aggregating server.</p>
    <p>The Event Type defines what kind of events are subscribed. Events of the given Event Type and all subtypes are returned.
       An event type can be selected in the dropdown field, or manually entered when marking the checkbox.
    </p>
