The PrognosisListTypeis a structuring node to collect predictions about future times when certain interaction with the machine may be necessary.
The PrognosisListTypeis formally defined in Table 65.

<Prognosis> is an optional placeholder for PrognosisTypenodes. Thus, the PrognosisListTypecan 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 NodeVersionand GeneralModelChangeEventTypecan be used to indicate those changes. The NodeVersionand the GeneralModelChangeEventTypeare intended to be used in the way defined in OPC 10000-3and 7.3.
