Custom Structure Technical Reference

What is a Structure?

A Structure is a user defined data type. Structures are used in Interface Methods to represent data types that are compatible with Historian and allow the custom collectors to interact with Historian.

Note: The abbreviation, TK stands for Toolkit.

For developing basic Custom Collectors, you should have knowledge about the following structures:

  • ihInterfaceTKPreCfgInfo, ihInterfaceTKCfgInfo - Maintains collector configuration information.
  • ihCollectorToolKitDefProperties - Maintains collectors specific properties.
  • ihInterfaceTKDataInfo - Maintains data information.
  • ihInterfaceTKRecordset - Maintains tag recordset.
  • ihTKTagProperties - Maintains tag properties.
  • ihTKTagFields - Maintains tag fields details
  • ihTKTagCriteria - Maintains tag criteria details.
  • ihTKDataType - Maintains tag data type
  • ihInterfaceTKHierarchicalBrowseResponse - Maintains hierarchical browse response information.
  • ihInterfaceTKASyncTagInfo - Maintains Unsolicited tag information.
  • ihInterfaceTKPolledTagInfo - Maintains Polled tag information.

The following are few more structures that are used for developing Custom Collectors:

  • ihTKTagRecordset
  • ihTKBlobData
  • ihTKHiddenValue
  • ihTKRawQuality
  • ihTKQuality
  • ihTKCommentData
  • ihTKComments
  • ihTKDataProperties
  • ihInterfaceTKASyncData
  • ihTKGetDataType
  • ihTKStatus
  • ihTKMessageTopic
  • ihTKCollectorCallbacks
  • ihTKTimeStruct
  • ihTKQualityStatus
  • ihTKQualitySubStatus
  • ihTKDataType
  • ihTKInterfaceType
  • ihTKCollectionType
  • ihTKTimeStampType
  • ihTKTimeResolution
  • ihTKTagId

} ihTKTagProperties;
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 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 deadband centered around the last collected value. The collector passes (to the archiver) any new value that falls outside the deadband and then centers the deadband around the new value.
InterfaceDeadbandPercentRange The current value of the compression deadband.
ArchiveCompression Indicates whether the archive collector compression is enabled for the tag.
ArchiveDeadbandPercentRange The current value of the archive compression deadband.
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 deadband.

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 deadband.
ArchiveAbsoluteDeadbanding Indicates if absolute archive deadband is enabled for this tag.
ArchiveAbsoluteDeadband Indicates the value for absolute archive deadband.
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.
