| 0x80B20000 | BadWaitingForResponseThe asynchronous operation is waiting for a response. |
| 0x80B30000 | BadOperationAbandonedThe asynchronous operation was abandoned by the caller. |
| 0x80B40000 | BadExpectedStreamToBlockThe stream did not return all data requested (possibly because it is a non-blocking stream). |
| 0x80B50000 | BadWouldBlockNon blocking behaviour is required and the operation would block. |
| 0x80B60000 | BadSyntaxErrorA value had an invalid syntax. |
| 0x80B70000 | BadMaxConnectionsReachedThe operation could not be finished because all available connections are in use. |
| 0x42080000 | UncertainTransducerInManualThe value may not be accurate because the transducer is in manual mode. |
| 0x42090000 | UncertainSimulatedValueThe value is simulated. |
| 0x420A0000 | UncertainSensorCalibrationThe value may not be accurate due to a sensor calibration fault. |
| 0x420F0000 | UncertainConfigurationErrorThe value may not be accurate due to a configuration issue. |
| 0x04010000 | GoodCascadeInitializationAcknowledgedThe value source supports cascade handshaking and the value has been Initialized based on an initialization request from a cascade secondary. |
| 0x04020000 | GoodCascadeInitializationRequestThe value source supports cascade handshaking and is requesting initialization of a cascade primary. |
| 0x04030000 | GoodCascadeNotInvitedThe value source supports cascade handshaking, however, the source's current state does not allow for cascade. |
| 0x04040000 | GoodCascadeNotSelectedThe value source supports cascade handshaking, however, the source has not selected the corresponding cascade primary for use. |
| 0x04070000 | GoodFaultStateActiveThere is a fault state condition active in the value source. |
| 0x04080000 | GoodInitiateFaultStateA fault state condition is being requested of the destination. |
| 0x04090000 | GoodCascadeThe value is accurate, and the signal source supports cascade handshaking. |
| 0x80E70000 | BadDataSetIdInvalidThe DataSet specified for the DataSetWriter creation is invalid. |
