1.5.2 Supports services and CIP objects
EtherNet/IP employs "Objects" as the collection of parameters. Each Object
defines its own parameters based on the structures of its Class, Instance, and Attribute.
In particular, Instance 0 defines the basic information of each Object such as its version
number and length. Instances 1 to N represent the parameter values required for each
device to establish a connection or obtain status information. User may access product
parameters via the service code supported by various Objects. Refer to the diagram
below:
