8.1.1 Supported CIP Objects
As in all implementations of CIP, EtherNet/IP shares the common Object Model. Objects are a common method to describe the specific application
implemented in a device.
Data is structured in Classes, Instances and Attributes:
A class is a group of objects with the same structure. These groups of objects within a class are called instances . Every instance provides the same
data elements called attributes . Each class provides services to access data or to change the state of an object.
