This section briefly describes the features of CIP device objects. For more details, see
THE
CIP NETWORKS LIBRARY, Volume 1: Common Industrial Protocol (CIP™)
, which is available
on the ODVA.org website.
Objects
Because EtherNet/IP is a CIP-based network, the network devices are described through sets
of objects. Each set of objects is organized in a specific manner with specific attributes so that
each network device operates in a certain way—that organization is the object model (or
device model). Every device with the same object model will operate in the same manner.
NOTE:
All device features must be described through objects in order to be access-
ible through CIP.
The following types of objects are used in a device profile:
l
Required objects: these must be present in every CIP device.
l
Application objects: these are specific to the type of device and its function.
l
Manufacturer-Specific objects: these are optional objects that are specific to each
device manufacturer.
The following figure shows a version of the EtherNet/IP object model with required and
optional objects.

EtherNet/IP Object Model
For the SmartMotor-specific model, see the object model for your SmartMotor application,
which is described later in this guide.
