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.
