9.7 EtherNet/IP objects
T
he EtherNet/IP (CIP) object model is comprised of various articles that describe specific
details of EtherNet/IP products.
Each of these articles addresses increasingly more specific details regarding the product.
These articles include the following:
Article Description
Object A general term that describes some functions of an EtherNet/IP
product.
Class A subset of objects that behave in a similar manner but contain
different data in their respective variables. Several objects that
contain common characteristics may fall into a single class. Each
object class has a unique hexadecimal identifier called a class
code.
Instance A specific occurrence of a given object. Since there can be several
occurrences of the same object within a device model, each
instance is designated with a numeric value.
Attribute One of many possible data elements in a given object or class
that can be written to or read from in an explicit message. Each
attribute is assigned a unique identification number.
Service Refers to a function that an object performs as a result of an ex-
plicit message request. Services are assigned a unique identifier
in hexadecimal and vary from object to object.
Knowledge of specific class, instance, attribute and service codes is necessary in order to
format an explicit message.
Explicit messages sent from an EtherNet/IP master to the UE410-EN1 can be used to read
or write the data sets of the UE410-EN1.
9.7.1 Full Data Set Transfer Object (72hex — one instance per UE410@EN1 module)
