4 Installation
4.1 Preparations for Trouble-free Operation
In the following section we have compiled some general information
for you that is important for trouble-free operation. If you are already
acquainted with this topic, you can skip to the next section. There,
you will learn about which conditions are necessary for installing the
gateway.
Cable routing
Route your cables separately in cable groups. This will protect your
gateway from any unintended electromagnetic interferences.
The following groups should be routed separately from each other:
Group Line
A Data and power supply lines for:
DC voltage below 60V
AC voltage below 25V
B Data and power supply lines for:
DC voltage between 60V and 400V
AC voltage between 25 and 400V
C Power supply lines above 400V
– You can route cables of the same group together in cable ducts or
bundles.
– Cables of group A and B:
– Route the groups in separate bundles or
– in cable ducts at a minimum distance of 10 cm from each other.
– Cables of group C
– Route the groups in separate bundles or
– in cable ducts at a minimum distance of 50 cm from the other
groups.
Installation

Shielding
Shield your cables. This will reduce any unintended electromagnetic
interferences.
Potential equalization
Potential differences occur when devices are connected to different
earths. These potential differences cause malfunctions.
To prevent malfunctions, you have to route an equipotential
equalization conductor.
When doing so, bear in mind the following points:
– Select an equipotential equalization conductor with low impedance.
– Select the following as a reference value for the cross-section of the
potential equalization cable:
– 16 mm2 for potential equalization cables of up to 200 m in length
– 25 mm2 for potential equalization cables of more than 200 m in
length
– Use potential equalization cables made of copper or galvanized steel.
– Connect potential equalization cables extensively with the earth rail.
– The smallest surfaces possible should be sandwiched between
potential equalization cables and signal cables.
If the devices of the control system are connected by shielded signal
cables that are earthed on both sides, the impedance must be 10%
of the shielding impedance.

4.2 Requirements
The Gateway was designed for use in a control cabinet.
üThe protection class of the control cabinet must be equivalent to at least
IP54.
üFor installation in the control cabinet you need a DIN rail 35 x 7.5mm
(EN50022).
◦ Install the DIN rail horizontally in the control cabinet according to the
manufacturers' specifications. When doing so, make sure that the
Gateway is at a sufficient distance from other devices.
NOTICE Your gateway could be damaged if temperatures are too high.
èMake sure that the ambient temperature in the control cabinet is less
than 60°C.
èKeep the ventilation slots unobstructed. These must not be covered by
cables etc.
èMaintain sufficient distance from other devices.
Illustration5: Distances for installation
◦ Connect each gateway component individually to functional earth.
When doing so, make sure that the power supplies of both gateway
components have the same ground.
ðYour control cabinet now meets all requirements for installing the
gateway.
Installation

4.3 Connecting Gateway Components
In order to attain a fully functional gateway, you have to interconnect
both gateway components.
◦ Connect an interconnect port to each gateway component using the
plug-in jumper (product number PR100204).
◦
Illustration6: Connecting gateway components
ðYou can now install the gateway in the control cabinet.
NOTICE Only ever interconnect 2 gateway components.
If you connect additional components, severe defects could result on all
devices.
Installation

4.4 Installing a Gateway in the Control Cabinet
◦ Hold the raster element of the gateway on the DIN rail.
◦ Press down the locking elements towards the gateway.
◦ Make sure that the gateway is firmly attached to the DIN rail.
Installation

4.5 Connecting a Power Supply
To connect the gateway component to the power supply, you need a
spring-loaded terminal (e.g. Metz-Connect SP995xxVBNC).
You have to connect each gateway component separately to a power
supply. Never interconnect functional earth and GND, otherwise the
galvanic isolation between gateway GND and fieldbus ground will be
removed. Instead, connect the functional earth with low impedance to
the potential equalization. You can then dispense with this
connection if the shield of the fieldbus cable is connected to the
potential equalization with lower impedance when entering the
control cabinet.
NOTICE Connect each of the two gateway components to its own power
supply
èEnsure in particular that no potential differences occur between the
GND pins (2).

4.6 Connecting a Gateway to the Fieldbus
To connect the gateway component to EtherNet/IP, you need Two
RJ45 connectors.
The pin assignment complies with the Ethernet standard.

5 Configuration
5.1 Supported Size of the Process Data
The gateway component for EtherNet/IP supports process data of a
length up to 480 bytes.
Type Direction Assembly
Instance
Size
Exclusive Owner Output (master -> slave) 100 up to 480 bytes
Input (slave -> master) 150 up to 480 bytes
Input Only Output (master -> slave) 254 0 bytes
Input (slave -> master) 150 up to 480 bytes
Listen Only Output (master -> slave) 255 0 bytes
Input (slave -> master) 150 up to 480 bytes
NOTICE Bear in mind that the maximum length of the process data is always
determined by the fieldbus with the shorter data length.
Example:
Ethernet/IP supports 480 bytes per direction.
PROFIBUS supports 244 bytes per direction.
In conjunction with Ethernet/IP / PROFIBUS this means that 244
bytes are transmitted and updated cyclically.
Configuration

5.2 Address Assignment
Setting IP Address
With the 8-pin address switch you can set the IP address of the
Gateways.
You can set values in binary format between 0-255.
Assigning IP Address
manually:
◦ Set any address between 1-254
ðThe gateway component uses the address 192.168.1.X with the net
mask 255.255.255.0 and gateway 192.168.1.1
◦ Open the website http://192.168.1.X
◦ Log on:
Logon data for the initial logon :
User: Admin
Password: 1701
◦ Click on the "Change Configuration" button
◦ Set the IP address required
◦ Confirm your entry by pressing the "Apply" button
◦ Set all address switches to "0"
◦ Restart the gateway component by switching this off and then on again.
ðThe set IP address is now used.
Receiving IP Address from
the DHCP Server
◦ Set the value "255" (all switches in the direction of the numbers) to
activate the DHCP mode.
ðAssign the IP address automatically from the DHCP server.
Setting IP Address using the
Master Software
◦ Set the value "0" (all switches to "Off")
ðThe gateway component uses the IP address that was last set using
the software.
◦ You can change this IP address at any time via the EtherNet/IP-
protocol or website.
◦ Restart the gateway component by switching this off and then on again.
ðThe set IP address is now used.
