| 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](https://help.tillit.cloud/tillit/knowledge-base/setting-up-tillit/edge/common-data-sources "mention")                                          |
| 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](https://help.tillit.cloud/tillit/knowledge-base/setting-up-tillit/edge/data-tags/edge-data-tag-options "mention"). |
