1 User instructions
Valve terminal type CPV...-GE-ASI-8E8A-Z-M8-CE has been
designed exclusively for controlling pneumatic actuators
and for use in bus systems in accordance with AS-Interface
specification 3.0. If used together with additional commer
cially available components, such as sensors and actua
tors, the specified limits for pressures, temperatures,
electrical data, torques etc. must be observed.
AS-Interface bus systems and valve terminals may only be
installed by personnel especially trained for this purpose.
Specifications on the design and addressing of your bus
system can be found in the manual for the AS-Interface
master.
Detailed information on the pneumatics 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-hand end
plate with low impedance (short cable with large
cross-sectional 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
unused address to each slave.
Note
– Valve terminal type CPV...-GE-ASI-8E8A-Z-M8-CE
contains 2 AS-Interface slaves. The valve terminal
behaves on the AS-Interface bus like two individual
valve terminals each with 4 inputs and 4 outputs
(valve solenoid coils).
Assignment of the inputs and outputs (valves):
– slave 1: inputs I0 … I3; outputs O0 … O3
– slave 2: inputs I4 … I7; outputs O4 … O7.
– Automatic addressing with the function “Automatic
address assignment” of the master is not possible.
– It is not necessary to parametrize the AS-Interface
slaves.
Address assignment
The assignment of the data bits to the inputs and outputs
of both independent slaves is shown in the following
diagram.

The address mapping depends on the configuration of the
master.

3.2 Assigning the AS-Interface addresses
Note
Addressing of valve terminal type CPV...-GE-ASI-8E8A-
Z-M8-CE is only permitted with addressing devices acc.
to specification 2.1 or higher.
Other addressing devices do not allow unique access to
the slaves, among other things, and may overwrite the
ID1 codes.
Recommendation:
For addressing use addressing device type ASI-PRG-ADR
with adapter cable type KASI-ADR from Festo.
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 < specification 3.0
Operation with AS-Interface masters less than specifica
tion 3.0 is fundamentally not possible.

Festo CPV-ASI-8E8A-Z-CE 2018-11b English 7
Address selector button
If by mistake, the same address is assigned to both slaves,
unique access to the slaves is no longer possible.
In this case you can use the address selector button to
decouple slave 1 from the AS-Interface bus. Press on the
button to unlock it and decouple slave 1. After this is
done, only slave 2 is visible, and the address of slave 2 can
be changed. If the AS-Interface bus voltage is connected,
this status will be indicated by the address selector LED
which will light up.
Note
The red address selector LED must not light up when
the valve terminal is operating.
If the address selector button has been unlocked:
Lock the address selector button by pressing it again
before the valve terminal is connected to the AS-Inter
face bus.
3.3 Address assignment of the valves
When addressed, the valve terminal type
CPV...-GE-ASI-8E8A-Z-M8-CE behaves like two individual
slaves each with 4 inputs and 4 outputs (see section 3.1).
Both valve terminal halves can be fitted with equipment as
follows:

3.4 Connecting sensors (PNP inputs)
Use cable type NEBU-... or KM8-M8-GSGD-... and plug
with union nut and M8x1 thread for connecting sensors.
Fasten the plugs/sockets 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.
Note
– The inputs have been designed in accordance with
IEC 1131-2 type 02.
– The inputs are short-circuit proof. In the event of a
short circuit the slave will be switched off. The
AS-Interface master then regards this slave as
missing. The slave reports back as functioning once
the short circuit has been eliminated.

3.5 Connect the AS-Interface bus and the load voltage
Note
The sensor supply derived from the ASInterfacepower
supply is protected against short circuits and overload.
It must not be connected to other voltages (for example
common ground).
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 the bus communication
fails.
Warning
SUse only PELV (protective extra-low voltage) circuits
as per EN 60204-1 for the electric power supply.
SAlso observe the general requirements for PELV
power circuits as per EN 60204-1.
SOnly use power sources which guarantee reliable
electrical isolation of the operating voltage as per
EN 60204-1.
By the use of PELV power units, protection against electric
shock (protection against direct and indirect contact) is
guaranteed in accordance with EN 60204-1.
