Good — The operation succeeded.
GoodSubscriptionTransferred — The subscription was transferred to another session.
GoodCompletesAsynchronously — The processing will complete asynchronously.
GoodOverload — Sampling has slowed down due to resource limitations.
GoodClamped — The value written was accepted but was clamped.
GoodLocalOverride — The value has been overridden.
GoodEntryInserted — The data or event was successfully inserted into the historical database.
GoodEntryReplaced — The data or event field was successfully replaced in the historical database.
GoodNoData — No data exists for the requested time range or event filter.
GoodMoreData — More data is available in the time range beyond the number of values requested.
GoodCommunicationEvent — The communication layer has raised an event.
GoodShutdownEvent — The system is shutting down.
GoodCallAgain — The operation is not finished and needs to be called again.
GoodNonCriticalTimeout — A non-critical timeout occurred.
GoodResultsMayBeIncomplete — The server should have followed a reference to a node in a remote server but did not.
GoodDataIgnored — The request specifies fields which are not valid for the EventType or cannot be saved by the historian.
GoodEdited — The value does not come from the real source and has been edited by the server.
GoodPostActionFailed — There was an error in execution of these post-actions.
GoodRetransmissionQueueNotSupported — The Server does not support retransmission queue and acknowledgement of sequence numbers is not available.
GoodDependentValueChanged — A dependent value has been changed but the change has not been applied to the device.
GoodSubNormal — The value is derived from multiple sources and has the required number of Good sources, but less than the full number of Good sources.
GoodPasswordChangeRequired — The log-on for the user succeeded but the user is required to change the password.
GoodEdited_DependentValueChanged — It is delivered with a dominant Variable value when a dependent Variable has changed but the change has not been applied.
GoodEdited_DominantValueChanged — It is delivered with a dependent Variable value when a dominant Variable has changed but the change has not been applied.
GoodEdited_DominantValueChanged_DependentValueChanged — It is delivered with a dependent Variable value when a dominant or dependent Variable has changed but change has not been applied.
GoodCascadeInitializationAcknowledged — The value source supports cascade handshaking and the value has been Initialized based on an initialization request from a cascade secondary.
GoodCascadeInitializationRequest — The value source supports cascade handshaking and is requesting initialization of a cascade primary.
GoodCascadeNotInvited — The value source supports cascade handshaking, however, the source’s current state does not allow for cascade.
GoodCascadeNotSelected — The value source supports cascade handshaking, however, the source has not selected the corresponding cascade primary for use.
GoodFaultStateActive — There is a fault state condition active in the value source.
GoodInitiateFaultState — A fault state condition is being requested of the destination.
GoodCascade — The value is accurate, and the signal source supports cascade handshaking.
Uncertain — The operation was uncertain.
UncertainReferenceOutOfServer — One of the references to follow in the relative path references to a node in the address space in another server.
UncertainNoCommunicationLastUsableValue — Communication to the data source has failed.
UncertainLastUsableValue — Whatever was updating this value has stopped doing so.
UncertainSubstituteValue — The value is an operational value that was manually overwritten.
UncertainInitialValue — The value is an initial value for a variable that normally receives its value from another variable.
UncertainSensorNotAccurate — The value is at one of the sensor limits.
UncertainEngineeringUnitsExceeded — The value is outside of the range of values defined for this parameter.
