# Getting Started

To create a new tag, click on `Tags` using the side navigation bar and click the ellipses in the top right corner to reveal the tag list dropdown. From here click the `+ Create Tag` button. You will be taken to a tag create form which contains the following parameters.

#### Name

The name should be a unique string identifier used to briefly describe this tag.

*i.e. Bearing Temperature #3 or 3-TI-1234*

#### Description

The description should be a more detailed string used to describe the tag.

*i.e. Residue compressor #3 drive-end bearing temperature*

#### *Usage*

Determine the nature of the tag’s behavior.

- **Input**
  - The tag is read-only (No data will be written from Koios → Device)
- **Output**
  - The tag is read/write (The tag’s output value will be written from Koios → Device)
  - The tag’s output is set by either a binding output or a parameter mapping. See the Output Tab section on the [tag detail](/v1/docs/52-tag-detail) page.

#### Device

Use the dropdown list to select an available device that the tag should belong to.

#### Use Device Set

When a protocol permits, Koios will allow redundant devices, making up a device set.

> *Device sets currently only supported by OPC-UA devices.*

#### Device Set

When using a device set, use the dropdown list to select an available device set that the tag should belong to.

#### Units

Engineering units of the tag (Visual only).

*i.e. GPM, PSIG*

#### *Range Min*

The minimum range of the tag. This can be used to normalize the tag’s data fed into a model.

#### Range Max

The maximum range of the tag. This can be used to normalize the tag’s data fed into a model.

#### Use Lookup Table

This can be used to convert non-numeric data to a number. For more information on lookups see the [Lookup Table page](/v1/docs/lookup-tab).
