Understanding 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)

When you use Historian Tags, you archive data by associating information with specific tags and tables. In other words, you establish a link between Tags and Historian Tables 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.

Configuring Historian Tags

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

After configuring the Historian Tables, you can start defining which Tags to archived with archive with the configured Historian Tables. 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. AlternativalyAlternatively, you can copy and past the Tag's name from Unified Namespace → Tags.
   
3. Configure the DeadBand, Deviation, and RateOgChange. The following section describes each of these configurations.
   
4. Select if FrameworX should conside consider an Absolute or Percentual DeviationDeadBandas the DeviationDeadBandType.
5. To finish, select the HistorianTable whe where the Tag's information will be archived.

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

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.
