The encoding of the status message fields for ApplicationInformationType 2 is specified in Table 154.

Table 154 – ApplicationInformationType status fields

Name	Type	Description
IsCyclic	Boolean	If TRUE the Publisher periodically updates the status. If FALSE the Middleware is responsible for detecting changes to the status.
Status	PubSubState	The current state of the Publisher. This value is mandatory.
NextReportTime	UtcTime	When the Publisher expects to send the next update. The field is present if IsCyclic=TRUE. The field is not present if IsCyclic=FALSE.

IsCyclic is set to FALSE if a PublisherId is used exclusively by a single application and the Message Oriented Middleware can detect when Publishers go offline. In these cases, the Publisher sends updates only when its state changes and the Message Oriented Middleware will send an update with PubSubState Error if the Publisher goes offline.

If IsCyclic is set to TRUE the Publisher only reports while they are Operational. The NextReportTime indicates when the Publisher will send an update. If the Subscriber does not receive updates and the NextReportTime is in the past, the Subscriber assumes the PubSubState Error.
