Messages is the node sending events, which are used for errors, warnings and messages. The respective references are formally defined in Table 54.
Prognoses contains a list of the current prognoses for machine tool operation. Reliability for any prognosis in the list will rely on the specific case and cannot be guaranteed to be precise.
The MessagesType is used to define the object sending events. These events are used for errors, warnings and messages.
The MessagesType is formally defined in Table 54.

To differentiate between errors, warnings and messages on the interface, the following convention shall be used, with regard to the recommendations in OPC 10000-5:
Errors have a high Severity between 667 and 1000 and are using an AlertType.
Warnings have a medium Severity between 334 and 666 and are using an AlertType.
Messages have a low Severity lower or equal to 333 and are using a NotificationEventType.
The PrognosisListType is a structuring node to collect predictions about future times when certain interaction with the machine tool may be necessary.
The PrognosisListType is formally defined in Table 55.

<Prognosis > is an optional placeholder for PrognosisType nodes. Thus, the PrognosisListType can have any number of prognoses as components, including none. If the number of prognoses in this list changes during the runtime of the OPC UA server, the NodeVersion and GeneralModelChangeEventType can be used to indicate those changes. The NodeVersion and the GeneralModelChangeEventType are intended to be used in the way defined in OPC 10000-3 and 7.3.
The PrognosisType is the most basic prognosis type and the supertype to more specific prognosis types. It is an abstract type, meaning it is not instantiated, only the subtypes are.
The PrognosisType is formally defined in Table 56.
