4.1 Mounting the bus node
®
, To mount the bus node, a product with I-Port interface is
required ("I-Port Device"), e.g. a valve terminal with I-Port
interface or the decentralised electrical connection box
CAPC.

Mounting of the bus node on the decentralised electric­
al connection box è CAPC assembly instructions
1.Check seal and sealing surfaces of the bus node and the
product with the I-Port interface. Replace damaged
parts.
2.Push the bus node onto the product carefully and
without tilting and press up to the stop.
3.Gently tighten down the self-tapping screws, using
existing threads.
4.Tighten the screws. Tightening torque: 0.7 Nm ± 10 %.

Electric voltage
Injury caused by electric shock, damage to machine
and to system
• For the electrical power supply, use only PELV circuits
in accordance with IEC 60204-1/EN 60204-1
(Protective Extra-Low Voltage, PELV).
• Observe the general requirements IEC 60204-1/
EN 60204-1 of the PELV power circuits.
• Use only voltage sources that ensure a reliable elec­
tric separation from the mains network in accordance
with IEC 60204-1/EN 60204-1.
• Always connect all circuits for operating and load
voltage supplies U and U
EL/SEN VAL/OUT
Fuse protection
The bus node supplies operating and load voltage to the
4
connected products via the I-Port interfaces X1 and X2.
• Secure operating voltage U and load voltage
EL/SEN
U separately.
VAL/OUT
• Take due account of the current consumption of con­
nected products during design and protection of the
power supply.
• Observe power rating of the power supply (no bus
node-internal overload protection for the connected
products) è 11.
• Ensure correct polarity (no bus node-internal reverse
polarity protection for the connected products).
Potential equalisation (earthing measures)
• Connect the functional earth (FE) connections of the
products connected via X1 and X2 to the earth potential
with a short conductor with the greatest possible cross

Data transmission errors
Malfunction
If installation has not been carried out correctly and
high transmission rates are used, data transmission
errors may occur, e.g. as a result of signal reflections
and attenuations.
• Connect screening to all network cables
• Wherever possible, only ground screening once (star-
shaped) to prevent ground loops
• Observe installation guidelines of the EtherNet/IP

Short circuit
Malfunction or damage to the electronics
• Use connection technology (interconnecting cables,
push-in connectors, adapters) with the required
degree of protection, e.g. plug connector
NECU-M-S-D12G4-C2-ET.
• Use cover caps to seal unused connections, e.g. cover
cap ISK-M12 è Accessories
• Mount cover of the DIL switches: Check seal, place
cover and push it down, tighten screws. Tightening
torque: 0.4 Nm ± 20 %.
• Do not remove sealing plug from underside of bus
node.
• Only when mounting the bus node on the decentral­
ised electrical connection box CAPC: Replace sealing
plug on underside of the bus node è Assembly
instructions CAPC.
5 Commissioning, configuration and parameterisation
Commissioning, configuration and parameterisation of
the bus node depends on the higher-order control sys­
tem. The basic approach and required configuration data
are explained in the following sections.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Note
Uncontrolled movement of the actuators, loose tubing,
undefined switching statuses of the electronics
Injury caused by moving parts, damage to machine and to system
• Before commissioning, ensure that the connected
products do not perform any uncontrolled move­
ments.
• Observe commissioning notices in the control system
documentation.
No automatic checking of configuration and parame­
terisation: The bus node and the connected products
also go into operation if configuration is incorrect.
Warning
5.1 Switch on the power supply
If the control system and network participants have sep­
arate voltage supplies, the following sequence is recom­
mended for switch-on:
1.Switch on the power supply to all network participants.
2.Switch on power supply to control system.
5.2 Setting the DIL switch

2.Perform additional settings è Table, item 3 ... 5.

5.3 Setting IP address
è Documentation of the control system
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
• Observe the basic addressing rules for the allocation
of the IP address, e.g. with respect to the use of
private or public address ranges.
• Check that the IP address can be used in the automa­
tion network.
• Ensure that there is no duplication of IP addresses in
use.
• Use DIL switches 1 for setting the addressing type or
for setting the host ID of the bus node.
The change of IP addressing in the bus node re­
quires a corresponding update in the higher-or­
der control system.
Examples
Host ID = 05
1 2 3 4 5 6
0 2
2 + 2 = 1 + 4 = 5
Set IP address:
192.168.1.005
2
; 22 AWG required for max.
Dynamic addressing
1.Make sure there is a DHCP server (e.g. BOOTP DHCP
server from Rockwell Automation) in the network.
2.Set all switch elements for address setting DIL1 (1...6)
and DIL2 (1...2) to "OFF".
3.With Festo Field Device Tool (FFT) or EtherNet/IP
Object, activate the "DHCP" option.
4.Switch bus node off and back on.
Saved addressing
1.Set all switch elements for address setting DIL1 (1...6)
and DIL2 (1...2) to "OFF".
2.Set the IP address with the Festo Field Device Tool (FFT)
or EtherNet/IP Object.
Note
3.Switch bus node off and back on.
Static addressing
1.Set the first three octets of the IP address with the
Festo Field Device Tool (FFT) or EtherNet/IP Object.
2.With all switch elements for address setting DIL1 (1...6)
and DIL2 (1...2), set the fourth octet (Host-ID) of the IP
address.
3.Switch bus node off and back on.
