 - **scaleoffset.type**: Allows to customise the way scale and offset is applied. See below for more details.
 - **unit**: an optional string value that will be added to the asset channel read to represent the unit of measure associated to that specific channel.
 - **listen**: if supported by the associated driver, allows to receive notifications by the driver on events. This flag currently has effect only inside Kura Wires.
 
+For the _READ_ and _READ/WRITE_ channels, the Asset typically asks the driver to provide a value based on the **value.type**.
+If the **scaleoffset.type** is _LONG_ or _DOUBLE_, the type requested will be one of these and the final value (after the scale and offset operation) will be transformed into the data type expected by **value.type**.

 ### Arithmetic with scale and offset
 The Asset supports applying a scale and offset to the values obtained by the attached Driver during read operations and to the values received in listen mode.
