Understanding HistorianTagsUnderstanding Historian Tags

When any Tag is registered into a Historian module to record the value over time or events, it is become a Historian Tag.

Historian Tags are used when you need to archive data, especially when dealing with process control and manufacturing, but not restricted to. You have the option to archive the following Historian Tag types:

• Integer
•  Decimal (float)
• Text (string)
• Digital (boolean)

a solution Tag, or an external Asset, is mapped to be archived or retrieved from an Historian, that configuration is called a HistorianTag. 

When you define HistorianTagsWhen you use Historian Tags, you archive data by associating information with specific tags and tablesHistorianTables in Storage Locations. In other words, you establish a link between Tags and Historian Tables HistorianTables to ensure systematic and organized data storage. You can also archive Template Tags. For this case, you can specify one of the Tamplate Tag's properties or archive all properties by entering only the main Tag name.

To utilize Historian Tags, you need to define which Tags are associated with each Historian Table.

Historian Tags allow users to archive data effectively. To add a tag, users enter the TagName and select a Historian table. This interface offers flexibility with optional settings and supports the use of template tags for storing specific properties or all properties associated with a main tag name.

Definition

Historian Tags is a tool that facilitates the archiving of data by associating it with specific tags and tables.

Purpose

The purpose of Historian Tags is to facility the store data.

Function

Historian Tags function by linking tags to a table into the ArchiveLocation.

Operation

Users operate Historian Tags by entering a tag name and choosing a Historian table for archiving. For template tags, users either select a specific property or store all properties by entering the main tag name.

Application

Historian Tags apply in scenarios where data collection, archiving, and retrieval are necessary. They are crucial in fields like process control, manufacturing, and other industrial applications where historical data analysis is essential.

Usage

To use Historian Tags, go to Historian → Historian Tags, enter the tag name, select a Historian table, and configure additional settings if needed. For template tags, users specify whether to store specific properties or all associated properties.

When archiving Tags created using DataTemplates, you don't need to specify all the properties.

The two pieces of Information that are mandatory to define an Historian Tags are:

TagName: variables that will archived, or retrieved.

HistorianTable: logical object that groups data and defines the storage location to which that variable will be connected.

Configuring HistorianTags

Before setting HistorianTags, you need to configure a HistorianTable. To Know more about creating and configuring HistorianTables, click here. You can also use the default one (Table 1).

Configuring Historian Tags

Before setting Historian Tags, you need to configure the Historian Tables. However, you can to use the default one (Table1) if you prefer.

After configuring the Historian Tables, you can start defining which Tags to archive with archive with the configured Historian TablesHistorianTables. To add and configure a single Tag, follow the steps below:

1. Access Historian

   →

   / Historian Tags.

2. On the TagName column, type the Tag name or select from the available list. Alternatively,

   you can

   copy and

   paste the Tag's name from Unified Namespace

   →

   / Tags.
   

3. Configure the DeadBand, Deviation, and

HistorianTags Properties

When configuring a Historian TagHistorianTag, you need to specify some properties which that will define how data will be archived. The following table describes each available property you can configure:

Property	Description
TagName	Enter a tag name or click ... to select a tag.	Specify the unique identifier of the Tag to be archived. To archive Template Tags, specify one of the Template Tag's properties or archive all properties by entering only the primary Tag name.
DeadBand	(Optional feature) Defines	DeadBand	When using the Save on Change option in the historian table, the DeadBand is how much the value must change (in Units) for the system to store the value. This configuration is considered when you use the SaveOnChange option in the historianHistorianTable.
Deviation	When using the Time DeadBand option in the historian table, the Deviation is (Optional feature) Specify how much the value must change (in Units) for the system to store the value. This configuration is considered when you use the TimeDeadBand option in the historian. This HistorianTable. If you define this property, its value overrides the Time Deadband TimeDeadband logging interval.
RateOfChange	When using the Time DeadBand option in the historian table, the RateOfChange is (Optional feature) Defines how much the value must change (in Units) by second , for the system to store the value. This configuration is considered when you use the TimeDeadBand option in the historian. This HistorianTable. If you define this property, its value overrides the Time Deadband TimeDeadband logging interval.
DeviationDeadBandType	(Optional feature) Determines the calculation method used to define the deadband Deadband value.
HistorianTable	Select the table that has the settings you want HistorianTable to use for when to save and how long to retain this tagwhen saving the Tag's value.[Other columns]	For definitions of other columns that are available in many tables, see Common Column Definitions.

Adding Tags for Data Logging

After you configure your tables for the tag historian, you can configure the tags that will be logged.

To configure the tags for the tag historian:

• Chose a previously created tag to store.
• Go to Historian > Historian Tags.
• Fill the TagName field with the previously chosen name.
• Fill in the HistorianTable field with the previously chosen table.
• If necessary, configure more settings, but in general cases it is not necessary.
