9. Ethernet/IP
9.1 General information
The EtherNet/IP™ is an industrial Ethernet network solution
available for manufacturing automation. The CIP™ (Common
Industrial Protocol) encompasses a comprehensive suite
of messages and services for a variety of manufacturing
automation applications, including control, safety,
synchronization, motion, configuration and information.
The CIP provides users with a unified communication
architecture throughout the manufacturing enterprise.
More information on the EtherNet/IP can be found at
www.odva.org.
9.1.1 Overview
The EtherNet/IP (Ethernet/Industrial Protocol) is a
communication system suitable for use in industrial
environments. The EtherNet/IP allows industrial devices to
exchange time-critical application information. These devices
include simple I/O devices such as sensors/actuators, as well
as complex control devices such as robots, programmable
logic c ontrollers, welders, and process controllers.
The EtherNet/IP uses CIP (Control and Information Protocol),
the common network, transport and application layers also
shared by ControlNet and EtherNet/IP. The EtherNet/IP then
makes use of standard Ethernet and TCP/IP technology
to transport CIP communications packets. The result is a
common, open application layer on top of open and highly
popular Ethernet and TCP/IP protocols.
The EtherNet/IP Messaging Forms:
•
Unconnected Messaging is used for connection
establishment and for infrequent, low priority messages
•
Connected Messaging utilizes resources which
are dedicated in advance to a particular purpose
such as real-time I/O data transfer. EtherNet/IP
Messaging Connections
•
Explicit Messaging Connections are general purpose
point-to-point connections. Messages are sent through
the TCP protocol
•
Implicit (I/O Data) Connections are established to move
application specific I/O Data at regular intervals. They are
often set up as one-to-many relationships in order to take
full advantage of the producer-consumer multicast model.
Implicit messages are sent through the UDP protocol
9.1.2 AC/DC drive profile
OPTE9 implements the CIP AC/DC drive profile.
In order to provide interoperability between devices from
different manufacturers, there must be a defined “standard”
in which those devices:
•
exhibit the same behaviour
•
produce and/or consume the same basic set of I/O data
•
contain the same basic set of configurable attributes.
The formal definition of this information is known as a
device profile
9.1.3 EDS file
You can provide configuration support for your device by
using a specially formatted ASCII file, referred to as the EDS
(Electronic Data Sheet). An EDS provides information about
the device configuration.
The information in an EDS allows configuration tools to
provide informative screens that guide a user through the
steps necessary to configure a device. An EDS provides
all of the information necessary to access and alter the
configurable parameters of a device. This information
matches the information provided by instances of the
Parameter Object Class. The CIP Object Library describes
the Parameter Object Class in detail.
OPTE9 has multiple EDS files, at least one per drive type.
You can download the drive specific EDS from Eaton web
site (www.eaton.com/drives). See also Chapter 6.1.9
“EIP Product code offset”.
9.1.4 LED functionality
The OPTE9 LEDs follow the CIP standard when the
EtherNet/IP is set as the active protocol. The LEDs on the
option board are not labeled as the CIP defines. The LED
labels are described in table below.

9.1.4.1 Module status LED
The Module status LED is labeled on the board as “BS”.
It shows the status of the module, that is, if a fault has
occurred or if the module has been configured. The MS LED
functionality is described in the table below.

State
Summary
Requirement
Steady off
No power
If no power is supplied to the device, the
module status indicator is steady off.
Steady green Device
operational
If the device is operating correctly, the
module status indicator is steady green.
Flashing green Standby
If the device has not been configured, the
module status indicator is flashing green.
Flashing red
Minor fault
If the device has detected a recoverable
minor fault, the module status indicator
is flashing red.
Steady red
Major fault
If the device has detected a non-
recoverable major fault, the module
status indicator is steady red.
