About this Manual
The “Industry Protocols” user manual describes how the device is connected
by means of a communication protocol commonly used in the industry, such
as EtherNet/IP and PROFINET.
The following thematic sequence has proven itself in practice:
XDevice configuration in line with the “Basic Configuration” user manual
XCheck on the connection Switch <–> PLC
XProgram the PLC
The “Installation” user manual contains a device description, safety instruc-
tions, a description of the display, and all the other information that you need
to install the device before you begin with the configuration of the device.
The “Redundancy Configuration” user manual contains all the information
you need to select a suitable redundancy procedure and configure it.
You will find detailed descriptions of how to operate the individual functions
in the “Web-based Interface” and “Command Line Interface” reference
manuals.
The Network Management Software HiVision/Industrial HiVision provides
you with additional options for smooth configuration and monitoring:
XConfiguration of multiple devices simultaneously.
XGraphical interface with network layouts.
XAuto-topology discovery.
XEvent log.
XEvent handling.
XClient / Server structure.
XBrowser interface
XActiveX control for SCADA integration
XSNMP/OPC gateway

1 Industr y Pr otocols
For a long time, automation communication and office communication were
on different paths. The requirements and the communication properties were
too different.
Office communication moves large quantities of data with low demands with
respect to the transfer time. Automation communication moves small
quantities of data with high demands with respect to the transfer time and
availability.
While the transmission devices in the office are usually kept in temperature-
controlled, relatively clean rooms, the transmission devices used in
automation are exposed to wider temperature ranges. Dirty, dusty and damp
ambient conditions make additional demands on the quality of the
transmission devices.
With the continued development of communication technology, the demands
and the communication properties have moved closer together. The high
bandwidths now available in Ethernet technology and the protocols they
support enable large quantities to be transferred and exact transfer times to
be defined.
With the creation of the first optical LAN to be active worldwide, at the
University of Stuttgart in 1984, Hirschmann laid the foundation for industry-
compatible office communication devices. Thanks to Hirschmann's initiative
with the world's first rail hub in the 1990s, Ethernet transmission devices such
as switches, routers and firewalls are now available for the toughest
automation conditions.
The desire for uniform, continuous communication structures encouraged
many manufacturers of automation devices to come together and use
standards to aid the progress of communication technology in the automation
sector. This is why we now have protocols that enable us to communicate via
Ethernet from the office right down to the field level.

2 EtherNet/IP
EtherNet/IP, which is accepted worldwide, is an industrial communication
protocol standardized by ODVA (Open DeviceNet Vendor Association) on
the basis of Ethernet. It is based on the widely used transport protocols TCP/
IP and UDP/IP (standard). EtherNet/IP thus provides a wide basis, supported
by leading manufacturers, for effective data communication in the industry
sector.
EtherNet/IP adds the industry protocol CIP (Common Industrial Protocol) to
the Ethernet as an application level for automation applications. Ethernet is
thus ideally suited to the industrial control technology sector.
Figure 2: Communicati on between the Controller (PLC) and the Switch
In particular, you will find EtherNet/IP in the USA and in conjunction with
Rockwell controllers.
For detailed information on EtherNet/IP, see the Internet site of ODVA at

After installing and connecting the Switch, you configure it according to the
“Basic Configuration” user manual. Then:
Use the Web-based interface in the Switching:Multicasts dialog to
check whether the IGMP Snooping is activated.
Use the Web-based interface in the Advanced:Industry Protocols
dialog to check whether EtherNet/IP is activated.
Use the Web-based interface in the Advanced:Industry Protocols
dialog to load the EDS (= EtherNet/IP configuration file) and the Icon onto
your local computer.
Note: If EtherNet/IP and the Router function are enabled concurrently mal-
functions of EtherNet/IP may occur, e.g. in conjunction with „RS Who”.
XDisable Router function via Web-based Interface:

Note: If e.g. a management program loads the Switch with SNMP
requests the I/O connection between controler (PLC) and Switch may be
temporarely disrupted. Cause in this case the Switch can further on
forward data packets the installation may also be operative.
The monitoring of the I/O connection to the Switch as failure criterion may
lead to a breakdown of the installation and therefore it is less suitable as
failure criterion.

2.2.2 TCP/IP Interface Object
The Switch supports an instance (instance 1) of the TCP/IP Interface Object
(class code f5hex) of EtherNet/IP.
In the case of write access, the Switch stores the complete configuration in
its flash memory. Saving can take 10 seconds. If the save process is inter-
rupted, for example, by a power cut, the Switch may crash.
Note: The Switch replies the configuration change „set request” with a
„response” before the saving of the configuration is finished.
