Data Types of Models¶

The attributes, measurement points, and commands of a model need to be described through data, and each piece of data has a type. The elements of EnOS models support the following data types.

Note

The supported data types vary depending on the selected element type and measurement point type.
For attributes and measurement points, if the data type is not enum or struct, you can select some built-in units in the system, such as kilometers, decimeters, and percentages.

Data Type	Description	Format Example
boolean	Boolean data, used to represent two states: True or False.	True
date	Date type data.	2024-09-30 15:30:00
dataTime	Date and time data, accurate to milliseconds.	2024-09-30T15:30:00.123Z
double	Double-precision floating-point data.	3.14159265359
float	Floating-point data.	3.14
integer	32-bit signed integer.	42
string	String type with a length of 1–1024 bytes. Subtypes include URL and Internationalized Strings.	https://www.example.com
object	Object type data representing a composite data structure, suitable for describing complex entities. Subtypes include data, dateTime, string, double, integer, float, enum, boolean	{“name”: “John”, “age”: 30, “isStudent”: false}
enum	Enumerated data.	Option 1
array	Array type data. Array members can only be of type integer, float, double, or string. The data type of the elements in the array must be specified during use.	[1, 2, 3, 4, 5]
map	Map type data, capable of defining custom key-value pairs or applying internationalized field templates, suitable for storing associated data. Subtypes include data, dateTime, string, double, integer, float, boolean.	{“key1”: “value1”, “key2”: 42}
