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.
