Overview
Data Templates refer to the feature that enables DataTemplates enable users to extend the platform's platform’s predefined data types by defining custom types with properties according tailored to their business needs. It This feature offers flexibility for modeling solution-specific data structures that standard types can't represent. Templates can represent can’t represent, such as machine data, equipment status, vessels, or and other asset attributes within an industrial plant. They are configured within the software platform and employed like any other data type to create tags. It allows for a tailored representation of real-world assets or process information, enhancing the accuracy and relevance of the data model.Data Templates facilitate the creation of tags with predefined attributes, organizing them into hierarchical structures that represent assets or information models. To employ a Data Template in a project, users need to create a new tag and select the appropriate template type. The tag will then inherit the defined attributes from the template, allowing users to access and manipulate these attributes as required throughout the project.

Defining DataTemplates
Data Templates Workflow
Defining Data Templates
Data Templates provide a way to create custom data structures that allow you to define reusable Tag configurations. They can be used to create hierarchical structures representing assets or information models, streamlining data management and improving system efficiency. For example, a template could be created for a specific type of equipment, with tags for its operational parameters and status information.To define a tag template:
Go to Unified Namespace →
Data TemplatesDataTemplates.
Click New.
The "Create New
Tag TemplateDataTemplate" dialog will open.
In the "New Name" field, enter a name for the tag type. In the Description, enter a description of the template. Click OK. The Templates tab displays with the name of the new template at the top of the tab.
To create a new attribute for this Data TemplateDataTemplate, type into the first row of the table next to it and press enter after adding all the information. The properties here are the same ones for Tags. See Creating and Editing Tags for more information.
To delete a template, select it from the User Custom Type drop-down list, then click Delete Item.
Using
Data TemplatesDataTemplates for custom Tag Types
DataTemplates Data templates streamline the creation of tags by supplying predetermined attributes. By employing these templates, users can efficiently manage data by upholding a logical and hierarchical structure representing assets or informational models.
To implement a Data Template DataTemplate in your project:
Navigate to the 'Tags' tab and click on 'New Item' to create a new tag.
In the 'Type' dropdown row, you can select the desired template. If a tag has already been created, select the desired template from the 'Type' column.
The tag will inherit the attributes from the chosen template

Description | Summarizes the purpose and details of the DataTemplate. |
| Info |
|---|
When setting properties for an array element or a DataTemplate member (like StartValue, Min, or Max), these values won’t show up in the DataTable inside the Designer. Instead, you can find them in the Dialog TagProperties or during Runtime. Also, keep in mind that changing a property for one element won’t update the rest. Each item in the Template or Array works independently, so modifications won’t apply across all instances automatically. |
