- All read-only variables have a
OpcUa_BadWaitingForInitialDataquality (0x80320000) intial initial value until a valid value is received from FledgePower. - All non-mandatory values will be set automatically be by the server if not received from a south device.
- If a mandatory value is missing, then the whole PIVOT object is not updated.
- As a standard OPC UA server, all functional data are organized under the
Root.Objectsnode of namespace 0 ( nodeId =i=85). - All data are stored under the namespace 1. Its URI is configured in protocol "
namespaces" parameter.
