1 User instructionsEnglish
Valve terminal type CPV..-GE-ASI-8E6A-Z has been de
signed exclusively for controlling pneumatic actuators and
is intended for use in bus systems in accordance with the
AS-Interface specification 2.1. If additional commercially-
available components such as sensors and actuators are
connected, the specifiedlimits for pressures, tempera
tures, electrical data, torques, etc. must not be exceeded.
AS-Interface bus systems and valve terminals may only be
installed by personnel especially trained for this purpose.
Detailed information on the design and addressing of your
bus system can be found in the manual for your AS-Inter
face master.
Information on the pneumatic components of the valve ter
minal can be found in the Pneumatics manual P.BE-CPV-... .
Warning
SSwitch off the power supply before connecting or
disconnecting plugs (otherwise this could lead to
functional damage).
SConnect the earth connection on the left end plate
with low impedance (short cable with large cross-sec
tional area) to the earth potential.
SCommission only a valve terminal which has been
fitted and wired completely.

3 Installation instructions
3.1 AS-Interface Addresses
Before connecting to the AS-Interface bus: assign an un
used address to each slave.
Please note
‒ The valve terminal type CPV..-GE-ASI-8E8A-Z contains
2 AS-Interface slaves. The valve terminal behaves on
the AS-Interface bus like two individual valve ter
minals each with 4 inputs and 3 outputs (valve sole
noid coils).
Assignment of the inputs and outputs (valves):
– Slave 1: Inputs I0...I3; outputs O0...O2
– Slave 2: Inputs I4...I7; outputs O4...O6.
‒ Automatic addressing with the function “Automatic
address assignment” of the master is not possible.
‒ It is not necessary to parametrize the AS-Interface
slave.
Address assignment
The assignment of the data bits to the inputs and outputs
of the slave shows the following figure:
Slave 1: IO code 7HSlave 2: IO code 7H
D0 D1 D2 D3
I/O I/O I/O I/O
I0 I1 I2 I3
O0 O1 O2 –
Inputs:
Outputs:
Data bits: D0 D1 D2 D3
I/O I/O I/O I/O
I4 I5 I6 I7
O4 O5 O6 –
E/A = bi directional (B)
The address mapping depends on the configuration of the
master.

Festo CPV10/14-ASI-8E6A 2018-11b English6
3.2 Assigning the AS-Interface addresses
Please note
Addressing valve terminal type CPV..-GE-ASI-8E6A-Z is
only permitted with addressers as per specification 2.1.
Other addressers do not permit clear access to the
slaves and in some cases overwrite the ID1 codes.
Recommendation: Use the Festo addresser type ASI-PRG-
ADR with adapter cable type KASI-ADR.
Factory setting: Slave 1: address #1, A slave
Slave 2: address #1, B slave
The addressing device scans the existing slaves in the
AS-Interface network.
SAssign the desired addresses to the two slaves one
after the other.
Operation with AS-Interface masters < Spec. 2.1
Operation with AS-Interface masters < Spec. 2.1 is possible
but both slaves must be programmed as A slave.
Recommendation: For operation with AS-Interface masters
< Spec. 2.1 use valve terminal type CPV..-GE-ASI-8E8A-Z
instead of CPV..-GE-ASI-8E6A-Z.

Festo CPV10/14-ASI-8E6A 2018-11b English 7
Address selector button
If the same address is assigned to both slaves, no clear
access to the slaves is possible.
In this case slave 1 can be disconnected from the AS-Inter
face bus with the aid the address selector button. You can
unlock the pushbutton by pressing it. Slave 1 will then be
disconnected from the AS-Interface bus. If the AS-Inter
face bus voltage is applied, the address selector LED will
light up to indicate that slave 1 has been disconnected
from the AS-Interface.
Please note
The red address selector LED must not light up when
the valve terminal is operated.
If the adress selector button has been unlocked:
Before connecting the valve terminal to the AS-Inter
face bus, therefore always lock the address selector
button by pressing it again.
3.3 Address assignment of the valves
During addressing, valve terminal CPV..-GE-ASI-8E6A-...
behaves like two individual slaves each with 4 inputs and
3 outputs (see sections 3.1 and 2).
The following fittings are possible for the two valve
terminal halves:

3.4 Connecting sensors (PNP inputs)
For connecting sensors use cable type KM8-M8-GSGD-...
and plugs with union nut, M8x1 thread.
Fasten the plugs with the aid of the union nut in order to
prevent unintentional loosening, e.g. due to shock. Seal
unused sensor connections with the protective caps type
ISK-M8. Only in this way can you comply with protection
class IP65.
Please note
The inputs are resistant to short circuits. If a short cir
cuit occurs, the slave will be switched off. The AS-Inter
face master regards this slave as missing. When the
short circuit is eliminated, the slave registers immedi
ately as capable of functioning.

3.5 Connecting the AS-interface bus and the load voltage
Please note
The sensor power supply for the inputs is provided via
the AS-Interface bus.
The power supply for the valves (outputs) is provided
by the additional supply: The valves must be supplied
separately with 24 V via the load voltage connection.
The AS-Interface has an integrated watchdog function
which resets the outputs if there is a bus communica
tion failure.
Warning
Use power supplies which guarantee reliable electrical
isolation of the operating voltage as per IEC/DIN EN
60204-1. Consider also the general requirements for
PELV circuits in accordance with IEC/DIN EN 60204-1.
By the use of PELV circuits, protection against electric
shock (protection against direct and indirect contact) is
guaranteed in accordance with IEC/EN 60204-1 (Electri
cal equipment for machines, General requirements).

Festo CPV10/14-ASI-8E6A 2018-11b English 11
Please note with branch lines:
– the total maximum length of the AS-Interface bus:
100 m (without repeater/extender).
– the cable length of the load voltage connection
(depends on the current consumption of the valve ter
minal and the fluctuations in the load voltage).
Pin assignment “Bus” (yellow cable):
1Pin 2: AS-Interface + (brown)
2Pin 1: AS-Interface - (light blue)

For connecting the valve terminal use the Festo cable
sockets type ASI-SD-FK... . You will then comply with
protection class IP65. Proceed as follows:
1. Press the AS-Interface cable into the upper part of the
cable socket.
2. Make sure that the cable is free of tension.
3. Place the cable socket in position and screw it tight
(max. 0.3 Nm).
Seal open flat cable ends with the Festo cable cap type
ASI-KK-FK or the cable sleeve type ASI-KT-FK. In this way
you will avoid leakage currents and comply with protection
class IP65.
