PubSub Model Status Event |
||||||
This EventType inherits all Properties of the SystemEventType. Their semantic is defined in OPC 10000-5.
The SourceNode is the NodeId of the PubSubConnectionType, PubSubGroupType, DataSetWriterType or DataSetReaderType Object associated with the Event.
The SourceName is the BrowseName of the SourceNode.
The ConnectionId Property is the NodeId of the PubSubConnectionType Object associated with the source of the status Event.
The GroupId Property is the NodeId of the PubSubGroupType Object associated with the source of the status Event. The GroupId is Null if a PubSubConnection is the source of the Event.
The State Variable is the current state of the Status Object associated with the SourceNode of the status Event.
This EventType indicates that a NetworkMessage could not be published because it exceeds the limits of transport. The PubSubTransportLimitsExceedEventType is formally defined in Table 294.
