EtherNet/IP Introduction
EtherNet/IP is one of three open network standards (DeviceNetTM,
ControlNetTM and EtherNet/IPTM), which all use a common application layer, the "Common Industrial Protocol" (CIPTM). This common
application layer and open software and hardware interfaces allow
a universal connection of automation components from the fieldbus level over the control level to the enterprise level.

The Common Industrial Protocol presents communication and
application in the object model. Predefined objects facilitate the
data exchange of different devices and manufacturers. By creating
various device profiles, additional user benefits were achieved.

TCP/IP Ethernet (IEEE802.3)
Network
EtherNet/IP is the implementation of CIP over TCP/IP and Ethernet
(IEEE 802.3).
The EtherNet/IP specification defines Layer 4, Layer 3 (Encapsulation
Protocol and usage of TCP/IP), Layer 2 (Usage of Ethernet IEEE
802.3), Layer 1 and Layer 0 (Physical Layer and Transmission Media).
EtherNet/IP supports data rates of 10 Mbit/s and 100 Mbit/s. Normally, a star topology using suitable (managed) switches is built.
The number of devices connected in an EtherNet/IP network
depends only on the available IP-Address space.
In contrast to DeviceNet, as of yet, the EtherNet/IP standard does
not specify a network power.

The Family of CIP Networks is specified and published by ODVA
(Open DeviceNet Vendor Association – www.odva.org) and CI (ControlNet International – www.controlnet.org).
CIP is a connection based protocol. It defines the exchange of I/O
data using I/O Messaging (or Implicit Messaging) as well as the
exchange of general data for configuration, diagnostic and management via Explicit Messaging. CIP thus provides 4 essential
functions to the user:

Besides factory automation with I/O-modules, valves, encoders,
drives and controls (PLC), the main field of application of
EtherNet/IP is the networking of both the control and the enterprise
level. Within the Family of CIP Networks, EtherNet/IP covers applications where medium to large amount of data with medium cycle
times (10 ms to 500 ms and above) need to be exchanged in the
network.

The EtherNet/IP Scanner software enables developers of PC based
or embedded products to quickly add EtherNet/IP Scanner Class
functionality to a product's feature set.
Applications for the EtherNet/IP Scanner Software are EtherNet/IPcapable controllers (PLC) as well as devices which must provide client
functionality in the network.
The EtherNet/IP Scanner Software provides I/O Server and I/O Client,

OVERVIEW
The EtherNet/IP Adapter module represents a powerful solution for
the implementation of EtherNet/IP Adapter functionality in devices
such as drives, I/O modules or encoders. For connection to the
application CPU, a serial interface or a shared memory interface is
available. The memory required for the data exchange is already on
the EtherNet/IP Adapter module, so that the interface of the application CPU only has to be connected to the module.
FURTHER INFORMATION
The technical details and features of the EtherNet/IP Adapter
module are subject to change. The latest information can be found
on the webpage.
ORDER NUMBER
For simple applications it is possible to run the application together
with the EtherNet/IP Adapter software on the module. Device
vendors can also integrate the hardware design instead of the add-on
module directly in their own circuit.
On request
A Host-API is supplied together with the EtherNet/IP Adapter
module, which allows the module to be controlled via its interface.
The access and the configuration to the local objects of the EtherNet/IP Adapter module is supported by the Host-API. It is also possible to save configurations on the EtherNet/IP Adapter module.
Process data are exchanged between application CPU and the
EtherNet/IP Adapter module via separate storage areas for input
and output data. The application can use 1.5 kBytes for process data
in each direction.
A baseboard is available as a supplement to the EtherNet/IP Adapter
module. This provides the power supply necessary for the evaluation
of the module as well as various bus connections. With the baseboard it is possible to implement a simple I/O device directly or to
connect processor modules of Phytec (phyCORE-XC161 and
phyCORE-LPC2294) or Spectrum Digital (eZdsp F2812) to the EtherNet/IP Adapter module via the integrated plugboards.
