RootCauseId |
0:NodeId |
The NodeId of the root cause of an alarm. This can point to another Node in the AddressSpace or a ConditionId, that is not necessarily represented as Object in the AddressSpace. Ideally, this points directly to the root cause. Potentially, it points to an alarm that has an additional root cause. Clients shall expect that they need to follow a path to find the root cause. If the root cause is unknown, the NodeId shall be set to NULL. |
|
RootCause |
0:LocalizedText |
Localized description of the root cause of an alarm. This can be the DisplayName of the Node referenced by RootCauseId or a more descriptive text. If the root cause is unknown, this should be described in the text. |
Its representation in the AddressSpace is defined in Table 19.
