1 Intended use
The bus node type CTEU-EP is intended exclusively for use
as a participant in EtherNet/IP or Modbus TCP networks.
The bus node may only be used in its original status
without unauthorised modifications and only in perfect
technical condition.
The specified limit values must be observed here.
The product is intended for use in industrial environ
ments. Outside of industrial environments, e.g. in com
mercial and mixed-residential areas, actions to suppress

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 IEC60204-1/EN60204-1
(Protective Extra-Low Voltage, PELV).
Observe the general requirements IEC60204-1/
EN60204-1 of the PELV power circuits.
Use only voltage sources that ensure a reliable elec
tric separation from the mains network in accordance
with IEC60204-1/EN60204-1.
Always connect all circuits for operating and load
voltage supplies U
EL/SEN
and U
VAL/OUT
.
Fuse protection
The bus node supplies operating and load voltage to the
connected products via the I-Port interfaces X1 and X2.
Secure operating voltage U

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).

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

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.
Warning

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.
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.

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

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.

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”.

or EtherNet/IP Object.
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)
