Parameters

Name	Description
Tagname	Tagname property of the tag.
Description	User description of the tag.
EngineeringUnits	Engineering units description of the tag.
Comment	User comment associated with the selected tag.
DataType	The data type returned in this column is the data type that is defined in the Historian Administrator application.
FixedStringLength	Zero unless the data type is FixedString. If the data type is FixedString, this number represents the maximum length of the string value.
InterfaceName	Name of the collector responsible for collecting data for the specified tag.
SourceAddress	Address used to identify the tag at the data source. For iFIXsystems, this is NTF (Node.Tag.Field).
CollectionType	Types of collection used to acquire data for the tag.
CollectionInterval	The time interval, in milliseconds, between readings of data from this tag.
CollectionOffset	The time shift from midnight, in milliseconds, for collection of data from this tag.
LoadBalancing	Indicates whether the data collector should automatically shift the phase of sampling to distribute the activity of the processor evenly over the polling cycle. This is sometimes called Phase Shifting.
TimeStampType	The type of time stamping applied to data samples at collection time: Source: The source delivers the timestamp along with the data sample. Collector: The collector delivers the timestamp along with the collected data.
HiEngineeringUnits	The high end of the engineering units range. Used only for scaled data types and input scaled tags.
LoEngineeringUnits	The low end of the engineering units range. Used only for scaled data types and input scaled tags.
InputScaling	Indicates whether the measurement should be converted to an engineering unit's value. When set to False, the measurement is interpreted as a raw measurement. With input scaling set to True, the system converts the value to engineering units by scaling the value between the Hi and Lo Scale. If InputScaling is not enabled, the system assumes that the measurement is already converted into engineering units.
HiScale	The high end value of the input scaling range used for the tag.
LoScale	The low end value of the input scaling range used for the tag.
InterfaceCompression	Indicates whether collector compression is enabled for the tag. Collector compression applies a smoothing filter to incoming data by ignoring incremental changes in values that fall within a dead band centered around the last collected value. The collector passes (to the archiver) any new value that falls outside the dead band and then centers the dead band around the new value.
InterfaceDeadbandPercentRange	The current value of the compression dead band.
ArchiveCompression	Indicates whether the archive collector compression is enabled for the tag.
ArchiveDeadbandPercentRange	The current value of the archive compression dead band.
CustomProp1	The general (or spare) configuration fields for the collector. The CustomProp1 column is not user-defined; it is different for each collector.
CustomProp2	The general (or spare) configuration fields for the collector. The CustomProp2 column is not user-defined; it is different for each collector.
CustomProp3	The general (or spare) configuration fields for the collector. The CustomProp3 column is not user-defined; it is different for each collector.
CustomProp4	The general (or spare) configuration fields for the collector. The CustomProp4 column is not user-defined; it is different for each collector.
CustomProp5	The general (or spare) configuration fields for the collector. The CustomProp5 column is not user-defined; it is different for each collector.
ReadSecurityGroup	The name of the Windows security group controlling the reading of data for the tag.
WriteSecurityGroup	The name of the Windows security group controlling the writing of data for the tag.
AdministratorSecurityGroup	The name of the Windows security group responsible for controlling configuration changes for the tag.
LastModified	The date and time that the tag configuration for this tag was last modified. The time structure includes milliseconds.
LastModifiedUser	The user name of the Windows user who last modified this tag's configuration.
InterfaceType	The collector responsible for collecting data for the tag.
ObsoleteField
UTCBias	The time zone bias for the tag. Time zone bias is used to indicate the natural time zone of the tag expressed as an offset from UTC (Universal Time Coordinated) in minutes. UTC is the international time standard, the current term for what was commonly referred to as Greenwich Mean Time (GMT).
ArchiveCompressionTimeout	Indicates the maximum amount of time from the last stored point before another point is stored, if the value does not exceed the archive compression dead band. The data archiver treats the incoming sample after the timeout occurs as if it exceeded compression. It then stores the pending sample.
InterfaceCompressionTimeout	Indicates the maximum amount of time the collector will wait between sending samples to the archiver.
SpikeLogic	Indicates whether the Spike Logic is enabled for the tag.
SpikeLogicOverride	Indicates whether the Spike Logic setting for this tag overrides the collector.
InterfaceAbsoluteDeadbanding	Indicates if absolute collector deadbanding is enabled for this tag.
InterfaceAbsoluteDeadband	Indicates the value for absolute collector dead banding.
ArchiveAbsoluteDeadbanding	Indicates if absolute archive dead banding is enabled for this tag.
ArchiveAbsoluteDeadband	Indicates the value for absolute archive dead banding.
StepValue	Indicates if the StepValue property is enabled for the tag.
TimeResolution	Indicates the timestamp resolution in seconds, milliseconds, or microseconds.
ConditionCollectionEnabled	Indicates whether condition-based collection is enabled.
ConditionCollectionTriggerTag	Tag condition-based collection trigger tag.
ConditionCollectionComparison	Tag condition-based collection comparison operator.
ConditionCollectionCompareValue	Tag condition-based collection compare value.
ConditionCollectionMarkers	Indicates whether to employ condition-based collection markers.
TagId	TagID associated with this tag.
