Click **Create**.
### Fields | Name | Description | | ---------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | 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). |
