Device Net classes

I do not understand the meanings of some terms used in the Instruction Manual of the Device Net.
1. Class
2. Instance
3. Attribute
I often see these three terms.

Answer

Class, instance, and attribute represents different grouping of objects.
Comparing object grouping to a mailing address, they can be considered as follows:
State (= class), city (=instance), and town (= attribute)
For inverter control, available parameters and operation commands are grouped into classes.
