5.3.4.2 Ethernet/IP
Ethernet/IP stands for Ethernet Industrial Protocol and defines an open
industry standard that extends the classic Ethernet with an industrial protocol.
This standard was jointly developed by ControlNet International (CI) and the
Open DeviceNet Vendor Association (ODVA) with the help of the Industrial
Ethernet Association (IEA).
Ethernet/IP is based on the TCP/IP protocol family and consequently uses the
bottom 4 layers of the OSI layer model in unaltered form so that all standard
Ethernet communication modules such as PC interface cards, cables,
connectors, hubs and switches can also be used with Ethernet/IP.
Positioned above the transport layer is the encapsulation protocol, which
enables use of the Control & Information Protocol (CIP) on TCP/IP and
UDP/IP.
CIP, as a major network independent standard, is already used with
ControlNet and DeviceNet.
Data exchange takes place with the help of an object model.
In this way, ControlNet, DeviceNet and Ethernet/IP have the same application
protocol and can therefore jointly use device profiles and object libraries.
These objects enable plug-and-play interoperability between complex devices
of different manufacturers.
Further information
A detailed description of the object model and its application is available in
Chapter 6.5.5 "Constant Registers".
5.3.4.3 BootP (Bootstrap Protocol)
The BootP protocol defines a request/response mechanism with which the
MAC-ID of a fieldbus node can be assigned a fix IP address.
For this a network node is enabled to send requests into the network and call
up the required network information, such as the IP address of a BootP server.
The BootP server waits for BootP requests and generates the response from a
configuration database.
The dynamic configuration of the IP address via a BootP server offers the user
a flexible and simple design of his network. The WAGO BootP server allows
any IP address to be easily assigned for the WAGO fieldbus
coupler/controller. You can download a free copy of the WAGO BootP server
over the Internet at: http://www.wago.com.
More information
The procedure for address allocation with the WAGO BootP Server is
described in detail in the Chapter "Starting up an ETHERNET TCP/IP
fieldbus node".
The BOOTP Client allows for dynamic configuring of the network
parameters:
