The category type that the OT device is classified as. The device type is also the function that the device plays on the OT network. For example:

 An IT device, such as a server, can be converted to an OT device, and the function it plays on the network is an HMI. Therefore, its class is **server** and its device type is **HMI**.

 **Note:** In some cases, there are OT devices with no OT function or OT devices where the device type is unknown. For OT devices with no OT function, select **No OT Function**. For OT devices where the device type is unknown, select **Unknown**.
