StatusChangeNotification

[ingdesarr1]

Good afternoon. I received the next StatusChangeNotification, but I dont know what it means. Can somebody help me? thanks

StatusChangeNotification(Status=StatusCode(value=2148270080), DiagnosticInfo_=DiagnosticInfo(SymbolicId=None, NamespaceURI=None, Locale=None, LocalizedText=None, AdditionalInfo=None, InnerStatusCode=None, InnerDiagnosticInfo=None))

This message is received when the PLC reset or recharge the program.

The NotificationMessage structure used in the Subscription Service set allows specifying different types of NotificationData. The NotificationData parameter is an extensible parameter whose structure depends on the type of Notification being sent. This parameter is defined in Table 159. Other types can be defined by additional parts of series of standards or other specifications based on OPC UA. The ExtensibleParameter type is defined in 7.12.

There may be multiple notifications for a single MonitoredItem in a single NotificationData structure. When that happens the Server shall ensure the notifications appear in the same order that they were queued in the MonitoredItem. These notifications do not need to appear as a contiguous block.

The StatusChangeNotification informs the Client about a change in the status of a Subscription.

How can I get the message of the statuscode with the library?

[AndreasHeine]

there must be a method like read_data_value or so! the datavalue contains the statuscode.
