This EventTypeis a base type for events which indicate an error or status change associated with a PubSubConnectionType, PubSubGroupType, DataSetWriterType or DataSetReaderType Object. The PubSubStatusEventTypeis formally defined in Table 293.

PubSub Model Status Event

This EventType inherits all Properties of the SystemEventType. Their semantic is defined in OPC 10000-5.

The SourceNode is the NodeIdof the PubSubConnectionType, PubSubGroupType, DataSetWriterType or DataSetReaderType Objectassociated with the Event.

The SourceName is the BrowseNameof the SourceNode.

The ConnectionId Property is the NodeIdof the PubSubConnectionType Objectassociated with the source of the status Event.

The GroupId Property is the NodeIdof the PubSubGroupType Objectassociated with the source of the status Event. The GroupIdis Null if a PubSubConnectionis the source of the Event.

The State Variableis the current state of the Status Objectassociated with the SourceNodeof the status Event.

This EventTypeindicates that a NetworkMessagecould not be published because it exceeds the limits of transport. The PubSubTransportLimitsExceedEventType is formally defined in Table 294.
