1 Instructions on this description
This description includes information for mounting the bus node on an I-port-com
patible device from Festo (e.g. valve terminal with I-port interface) and for installa
tion of this combination in a higher-level control system.
AS-Interface® and TORX® are registered trademarks of the respective
trademark owners in certain countries.
2 Intended use
The bus node type CTEU-AS has been designed exclusively for use as a slave on
the AS-interface fieldbus. It may only be used in its original status without unau
thorised modifications and only in perfect technical condition.
The bus node is intended for use in an industrial environment. Outside of industrial
environments, e.g. in commercial and mixed-residential areas, actions to suppress
interference may have to be taken.
3 Target group
The target group for this description consists of trained specialists in control and
automation technology who have experience with installation of stations on the
AS-interface fieldbus.
4 Mounting
Warning
Danger of injury to people, damage to the machine and system resulting from
uncontrolled movements of the actuators and undefined switching states
Switch off the operating and load voltage supplies.
Switch off compressed air supply.
Exhaust the pneumatics valve terminal.
Note
Damage to the electronics
The bus node includes electrostatically sensitive devices.
Do not touch any electrical/electronic components.
Observe the handling specifications for electrostatically sensitive devices.
Note
Use cover caps to seal unused connections. You will then achieve degree of pro
tection IP65/IP67.
Information on mounting the bus node on the decentralised electrical
connecting plate CAPC-... can be found in the mounting instructions that
accompany the connecting plate.
The bus node CTEU-AS supports only the X1 connection of the electrical
connecting plate CAPC-.... The X2 connection on the electrical connecting
plate CAPC-... is without a function for the CTEU-AS bus node.
For mounting the bus node on a valve terminal with I-Port interface, proceed as
follows:
1. Inspect the seals and sealing surfaces on bus node and valve terminal.
2. Plug the bus node onto the valve terminal in the right position and without tilt
ing.
3. Screw the three self-tapping screws in by hand. You can use the threads already
present when you screw it in again.
4. Tighten the screws by hand in diagonally opposite sequence, with a tightening
torque of 0.7 ± 0.1 Nm.
5 Connection and display components
The following electrical connection and display components can be found on the
bus node:

(è chap. 6 )
Fig. 1
6 Connect AS-interface bus and auxiliary power supply
The bus node also supplies voltage to equipment connected via the I-port inter
face.
Warning
Danger of electric shock
Only use PELV circuits in accordance with IEC/EN 60204-1 (protective extra-
low voltage, PELV) for the electrical power supply.
Observe also the general requirements for PELV power circuits in accordance
with IEC/EN 60204-1.
Only use voltage sources which guarantee reliable electrical isolation of the
operating voltage in accordance with IEC/EN 60204-1.
Through the use of PELV circuits, protection against electric shock (protection
against direct and indirect contact) is ensured in accordance with IEC/EN 60204-1.
Observe with branch lines:
– the maximum overall length of the AS-interface bus (100 m without repeater/
extender)
– the line length of the load voltage connection cable (depends on the current
consumption of the valve terminal and fluctuations in load voltage).

Note
Electromagnetic interference
Make the connection to functional earth via the connected device or the elec
trical connecting plate CAPC-....
Functional test:
– The LED “PS” is illuminated green when the power supply is correctly presented.
– The LED “X1” is lit green if a device is connected and the I-Port communication is
ready to function (è chap. 8).
7 Basic settings for fieldbus communication
7.1 Removal of the DIL switch cover
To set the DIL switches, the cover must be removed:
1. Switch off the power supply.
2. Unscrew the two mounting screws of the transparent cover and remove the
cover.
7.2 Setting the DIL switches
The bus node has a DIL switch group with 2 DIL switches. Set the valve configura
tion with DIL switches 1 and 2.

7.3 Mounting of the DIL switch cover
1. Place the cover carefully on the bus node. Make sure that the seal is seated
correctly!
2. Tighten the mounting screws with max. 0.4 Nm with a Torx screwdriver
(size T10) or a slot screwdriver that fits.
7.4 Address allocation
Before connecting to the AS-Interface bus: Assign a free address to the slave.
Addressing can be performed via an AS-interface addressing device in accordance
C.S.2.1, an addressing cable and through an AS-interface master.
The number of connected solenoid coils is set through the DIL switches
(è chap. 7.2). Depending on this setting, the number of slave addresses, IO and
ID code are automatically configured and saved (è subsequent table).

indicator
Status and significance
LED illuminated green:
– AS-interface voltage applied
– no error is present.
LED is off:
– AS-Interface voltage not applied
LED illuminated red:
– AS-interface address not set (equals 0)
– no communication
LED flashes red/green:
– peripheral fault (e.g. no additional voltage, no I-port)

Note
AS-interface has an integrated watchdog function, which can be activated/deac
tivated via the parameter bit P0.
Valid is:
– P0 = 1 è Watchdog activated (delivery status)
– P0 = 0 è Watchdog deactivated
If Watchdog is activated, the outputs are reset as soon as bus communication
malfunctions.
