## What are Control Parameters?

Control Parameters are the names for the variables whose values would be sent to assets in conditions that quality the Rules within [Recipes](/tillit/knowledge-base/setting-up-tillit/recipe-management/recipes.md).

| Name                | Name of the Control Parameter                                                                                                                                                             |
| Unit of measurement | <p>Unit of measurement for this CP.<br>For example, it would be "C" for "Temperature", or "minutes" for "Blanching duration"</p>                                                          |
| Description         | Description of the CP                                                                                                                                                                     |
| Data Type           | <p>Choose between Number, Text, or Boolean.<br>For example, "Temperature" would have "C" for Uom, but "Number" for data type.</p>                                                         |
| Constraint Min      | The absolute minimum the value of the CP can have. See [Process Variable](/tillit/knowledge-base/setting-up-tillit/configuration/process-variable.md)for another example of this concept. |
| Constraint Max      | The absolute maximum the value of the CP can have. See [Process Variable](/tillit/knowledge-base/setting-up-tillit/configuration/process-variable.md)for another example of this concept. |
| Display Order       | The display order of the CP in the entity manager list.                                                                                                                                   |

## Next steps

Now you are ready to create Rules for [Recipes](/tillit/knowledge-base/setting-up-tillit/recipe-management/recipes.md) using these Control Parameters :smile:
