### Required Parameters

To add an analog input or an analog output device, such as voltage transducer, the following parameters are required.

<ParamField path="id" type="string" required>
  A unique identifier for the device.

  **Example:** `transducer`
</ParamField>

<ParamField path="type" type="string" required>
  Indicates the type of device. For this type of device, it is always `analogInputOutput`.

  **Example:** `analogInputOutput`
</ParamField>

<ParamField path="addressMap" type="string" required>
  The name of the device’s address map on the controller.

  **Example:** `vmt_address_map`
</ParamField>

<ParamField path="disabled" type="bool" required>
  Indicates whether the device is enabled or disabled. A value of true means the device is disabled, while false means the device is enabled.
</ParamField>
