A.4.6 Interpretation of nvoStatus
The object status contains a great deal of information about the status of a node. Several bits have
meaningassignedwhichisspecictoHoneywellAnalytics.
For example fault_alert (Honeywell nomenclature) has been mapped to mechanical_fault
(LonMark nomenclature).
The following table lists all of these assignments. Blank entries correspond to unimplemented
status bits.
