# Edge Data Tag

### Overview

A more detailed description of Edge and Edge Data Tags can be found here - [Edge](/tillit/knowledge-base/setting-up-tillit/edge.md)[.](/tillit/knowledge-base/setting-up-tillit/edge.md) We suggest reading this first and then adding the edge data tag to the Asset.

### Create a new Edge Data Tags

Go to ***Settings > Asset Hierarchy > Assets***

Then **select the relevant Asset.** On the asset details page find the **Edge Data Tag** panel and click to open. Click **Create**.

| Name \*          | Enter a name for the Data Tag.                                                                                                                                                                                                                    |
| Source Address   | The address of the data tag on the source. Check the data source type you are using and find the guide under [Common Data Sources](/tillit/knowledge-base/setting-up-tillit/edge/common-data-sources.md)                                          |
| Source Data Type | Whether the data tag is a boolean (digital), number or string (text)                                                                                                                                                                              |
| Template         | How TilliT should interpret this data tag.                                                                                                                                                                                                        |
| Process Variable | If you set a process variable, TilliT will store the data value as a time series.                                                                                                                                                                 |
| Data Source      | If you want to include this tag in the poll cycle. Setting to inactive will cause the edge to not read the tag.                                                                                                                                   |
| Options          | Special configuration tools that allow you can set to define advanced behaviour. If your value has a rollover, then this can help, see [Edge Data Tag Options](/tillit/knowledge-base/setting-up-tillit/edge/data-tags/edge-data-tag-options.md). |
