sensors and actuators are connected.
Please comply also with national and local safety laws
and regulations.
Target group
This manual is directed exclusively at technicians who
are trained in control and automation technology and
who have experience in installing, commissioning, pro-
gramming and diagnosing network modules on the

1.1 General instructions on installation
WARNING
Before undertaking installation or maintenance work,
switch off the following:
• the compressed air supply
• the operating voltage for the bus
interface/internal logic
• the load voltage supply to the valves.
You will thereby avoid:
– Uncontrolled movements of loose tubing.
– Unintentional movements of the connected actuators.
– undefined switching states of the electronic compo-
nents.
CAUTION
The CPV valve terminal contains electrostatically
vulnerable components.
• Do not therefore touch the contact surfaces of the
components.
• Observe the regulations for handling
electrostatically vulnerable components.
You will thereby prevent damage to the electronic com-
ponents.

1.2 Setting the node address and the field bus baud rate
The following switches are under the switch cover on
the sub-base of the CPV valve terminal:
– DIL switch for setting the field bus baud rate
– address selector switch for setting the node address
Opening and closing the cover
• Opening: Unscrew the 4 screws in the switch cover
and remove them. Lift up the cover.
• Closing: Replace the cover. Tighten the 4 screws in
diagonally-opposite sequence.

Setting the node address
You can set the node address of the CPV valve termi-
nal with the address selector switches. The switches
are numbered from 0 to 9. The arrow on the switches
indicates the units or tens figure of the node address
which is set.
Address selector switch for UNITS figures
Address selector switch for TENS figures
Fig. 1/3: Address selector switch
PLEASE NOTE
Node addresses may only be assigned once per
module/scanner.
Recommendation:
Assign the numbers in ascending order. If necessary,
take into account the machine structure of your system
when assigning the addresses.
1. Installation

The following node addresses are permitted: 0...63
Proceed as follows:
1. Switch off the voltage supply for the bus interface/in-
ternal logics as well as the load voltage supply for
the CPV valves.
2. Assign a non-reserved node address to the CPV
valve terminal.
3. Use a screwdriver to set the arrow on the relevant
address selector switch to the units or tens figure of
the desired node address.

Setting the field bus baud rate
Next to the address selector switches there is a DIL
switch with two switch elements. These are numbered 1
and 2. The position ON is marked.
PLEASE NOTE
Set the field bus baud rate of the CPV valve terminal
so that it corresponds to the setting of your scanner.

1.3 Connecting the CPV valve terminal
1.3.1 Connecting cable
Use a twisted, screened/shielded 4-wire cable for the
field bus. The bus interface and the internal logics of
the CPV valve terminal are supplied with power via the
field bus cable.
Field bus cable
PLEASE NOTE
• Always refer to your PLC manual or scanner
manual for the correct type of cable. Also take
into account the distance and the baud rate
selected.
• Selet the appropriate cable diameters.
Notice the drop in voltage:
– on the supply cable for the bus interface
and
– on the internal logics of the CPV valve terminal.

The following table shows the guide values for the
maximum distance depending on the baud rate se-
lected. Exact details can be found in the manuals for
your control system and scanner.

• Use a load voltage cable with sufficient diameter.Load voltage
cable
• Avoid long distances between the power unit and the
CPV valve terminal.
Long load voltage cables reduce the voltage supplied
by the power unit.
• If necessary, ascertain the suitable cable diameter
and the maximum permitted cable length.

1.3.2 Preparing the connecting cable
The connections for the field bus interface and for the
load voltage have been designed in the form of plugs.
The pin assignment of the field bus interface and the
load voltage connections can be found on the following
pages.
For the load voltage connection, use plugs from the
Festo range corresponding to the outer diameter of the
cables used (see Appendix A, Accessories).

Ready-to-use cables with plugs from various manufac-
turers are available for the field bus connection (see
