Object Type
Description
Variable
A single value such as a UNSIGNED8, a Boolean, a float and an INTEGER16
Array
An object with multiple data fields composed of multiple variables of the same data
type such as UNSIGNED16. The Sub-index 0 data belongs to UNSIGNED8, so it’s not
classified as array data
Record
An object with multiple data fields composed of multiple variables of the same data
type. The Sub-index 0 data belongs to UNSIGNED8, so it’s not classified as record
data.
