Grounding/Protection/Fuses
• When handling the product, please ensure that environmental factors (personnel, work
space and packaging) are properly equalized. Do not touch any conducting parts.
Cables
• Use shielded cables with copper braiding or tinned copper braiding. This reduces elec-
tromagnetic interference and increases signal quality. Measurement errors, data trans-
mission errors and interference due to excessive voltage can be prevented.
• Maintain spacing between control, signal and data lines and the power supply lines.
• Observe permissible temperature range of connecting cables.
• Use appropriate strain relief.
2.3 Mechanical Safety
• As the installer of the system, you are responsible for ensuring the necessary touch-
proof protection. Follow the installation guidelines for the specific application.
• Before startup, please check the product for any damage that may have occurred dur-
ing shipping. Do not put the product into operation in the event of mechanical damage.
• Do not open the product housing.
• The product is an open-type device and is designed for installation in an additional en-
closure, which supplies the following safety aspects:
– Restrict access to authorized personnel and may only be opened with tools.
– Ensure the required pollution degree in the vicinity of the system.
– Offer adequate protection against direct or indirect contact.
– Offer adequate protection against UV irradiation.
– Prevent fire from spreading outside of the enclosure.
– Guarantee mechanical stability.

3.5 Connections
3.5.1 RJ-45 Interfaces
The connection to ETHERNET-based fieldbuses is established via two RJ45 connectors
(see figure “RJ45 Interface, X5/X6”), also called “Western plugs,” which are connected to
the fieldbus controller via an integrated switch.
The integrated switch works in store-and-forward mode and supports 10/100Mbit/s trans-
mission speeds, as well as full and half-duplex transmission modes, for each port.
The RJ45 sockets are wired in accordance with the specifications for 100BASE-TX.
The ETHERNET standard stipulates a twisted pair cable of at least Category 5e as a con-
necting cable. S/UTP (Screened Unshielded Twisted Pair) and STP (Shielded Twisted
Pair) type cables with a maximum segment length of 100m can be used.

EtherNet/IP Communication Module
4Fieldbus Description
4.1 Technology
4.1.1 EtherNet/IP Overview
EtherNet/IP is based on the TCP/IP protocol family and handles the lower four layers of
the OSI layer model in unmodified form so that all standard ETHERNET communication
modules, such as PC interface cards, cables, connectors, hubs, switches etc., can be
used with EtherNet/IP in the same way. The “Encapsulation Protocol,” with which the
“Common Industrial Protocol” (CIP) is superimposed on TCP/IP and UDP/IP, is located
above the transport layer.
CIP is already used as a major network-independent standard for ControlNet and De-
viceNet. Therefore, transferring an application to one of these systems is very feasible
and easy. The data exchange is based on an object model.
ControlNet, DeviceNet and EtherNet/IP all have the same application protocol and can
therefore use common device profiles and object libraries. These objects enable plug-
and-play interoperability between complex devices from different manufacturers.
4.1.2 EDS File
The “Electronic Data Sheet” (EDS) file contains the product characteristics and informa-
tion regarding its communication capabilities. The EDS file required for operation is im-
