Installation
5.2 Connect fieldbus
5.2.1 Fieldbus cable
NOTICE
Data transmission errors due to signal reflections and signal attenuation due to incorrect installation
and high transmission rates.
Transmission errors can be caused by:
• Missing or incorrect terminating resistor
• Missing shield connection
• Junctions
•Transmission over long distances
• Unsuitable cables.
Observe the cable specification. Cable type information è Controller manual.
NOTICE
Property damage when the product is mounted in a machine so it can move.
• Install strain relief for the fieldbus cable on the moving part of the machine.
• Observe the regulations of IEC/DIN EN 60204-1.
•Use a twisted, shielded 2-wire line as the fieldbus cable.
Cable specification according to EN 50170 (cable type A)
Surge impedance 135 … 165 Ω (3 … 30 MHz)
Capacitance per unit length <30 nF/km
Loop resistance <110 Ω/km
Core diameter >0.64 mm
Wire cross section >0.34 mm2

Bus length
Information on the bus length è 5.2.2 Fieldbus baud rate and fieldbus length and in the control
system manuals.

5.2.2 Fieldbus baud rate and fieldbus length
NOTICE
Malfunctions due to impermissible fieldbus lengths.
The permissible fieldbus segment lengths depend on the baud rate used.
• Observe the maximum segment length (cable length without repeater) if the CPX terminal is con-
nected to a fieldbus segment.
• Avoid branch lines.
The product automatically sets itself to one of the following baud rates:
Baud rate Maximum segment length
9.6; 19.2; 93.75 kbaud 1200 m
187.5 kbaud 1000 m
500 kbaud 400 m
1500 kbaud 200 m
3000 … 12000 kbaud 100 m
Tab. 7: Maximum fieldbus segment lengths depending on the baud rate
5.2.3 Connection options
Connection with Festo fieldbus plug
Achieving IP65 degree of protection
• Seal unused ports with protective caps or blanking plugs.
• Observe the assembly instructions of the fieldbus plug.
The product is easily connected to the fieldbus with the Festo FBS-SUB-9-GS-DP-B fieldbus plug. The
fieldbus plug can be disconnected from the product without interrupting the bus line (T-TAP function).
The clamping clip in the Festo fieldbus plug is internally only capacitively connected to the metal
housing of the Sub-D connector. This prevents compensating currents from flowing through the shield
of the fieldbus cable.
The following is switched with the switch in the fieldbus plug:
–OFF switch position:
The bus connection is switched off and the continuing fieldbus line is switched on.
–ON switch position:
The bus connection is switched and the continuing fieldbus line is switched off.

Installation
Connection with M12 adapter (reverse key coded)
When using the adapter FBA-2-M12-5POL-RK the product is connected to the fieldbus via M12 plugs.
The plugs have an inverted mechanical coding (reverse key or B-coded), which prevents the incoming

without interrupting the bus line (T-TAP function). The connection to the fieldbus uses a 5-pin M12
plug with PG9 fitting. The second connector socket is used to continue the fieldbus.

Connection with fibre optics
The PROFIBUS DP interface conforms to the EN 50170-2 specification and supports the control of
network components for fibre optics.
• Use fibre optic cables for transmission in environments with high levels of interference and to
increase the range at high transmission speeds.
Example of fibre optic network components:
–SIEMENS Optical Link Module (OLM) for PROFIBUS plus
–SIEMENS Optical Link Plug (OLP) for PROFIBUS (IP20)
–Harting Han-InduNet® media converter IP65 in combination with adapter cable for Festo products
(optical data transfer in the DESINA installation concept).
5.3 Bus terminal with terminating resistors
If the valve terminal is at the start or end of the fieldbus system, a bus termination is required.
•Use a bus termination at both ends of a bus segment.
Recommendation
• Use the Festo prefabricated fieldbus plug for the bus termination. A suitable resistor network is
integrated in the housing of this plug connector.

5.4 Power supply
5.4.1 Cables for the power supply
• Use a power supply cable with a sufficient cross-section.
• Avoid long distances between the fixed power supply and the CPV valve terminal. Long cables
reduce the voltage supplied by the fixed power supply.
• If necessary, calculate the suitable cable cross-section and the maximum permissible cable length.
• For the power supply connection, use plugs from the Festo catalogue to match the outside diameter
of the cables used è www.festo.com/catalogue.

Assembly
After selecting a suitable cable, connect it as follows:
1. Open the socket by loosening the middle knurled nut.
2. Open the strain relief on the rear part of the housing and feed the cable through.
3. Strip the ends of the conductors by 5 mm and fit wire end sleeves.
4. Connect the wire ends.
5. Put the connection part back on the housing of the socket and screw it in. Pull the cable back far
enough so there are no cable loops in the housing.
6. Tighten the strain relief firmly.

5.4.2 Select power pack
WARNING
Risk of injury due to electric shock.
• For the electric power supply, use only PELV circuits that ensure a reliable electric disconnection
from the mains network.
• Observe IEC 60204-1/EN 60204-1.
The use of PELV circuits ensures protection from electric shock (protection from direct and indirect
contact) in accordance with IEC/EN 60204-1 (Electrical equipment of machines, General require-
ments).
The power requirement of a CP system depends on the number of CP modules and valve coils.
Recommendation:
•Use regulated power packs.
•When selecting the fixed power supplies, check that they supply sufficient power. To do this,
calculate the total power requirement according to the following table.
Total power consumption
The table below shows the calculation of the total power consumption for a CP system. The values
given are rounded up.
Power consumption f CP electronics (pin 1) Total
CPV master max. 100 mA
CPV valve terminal max. 40 mA
CPA valve terminal 20 mA
CP input module max. 40 mA

5.4.3 Connecting the power supply
NOTICE
Unexpected response of the valve terminal due to switch-on test pulses if the valve terminal is
supplied with load voltage via an output of a "safety-related I/O module".
• Ensure that switch-on test pulses are safely suppressed or switched off.
NOTICE
As part of the emergency off design check what actions for the machine/system are required to set the
system to a safe state in the case of an emergency off event:
• Switch off the load voltage of the valves and output modules in the secondary circuit of the power
pack.
• Switch off the compressed air supply.
Energy stored in the input circuitry of valve terminals can cause the valves to switch off with a delay
after the load voltage has been switched off:
• Detect the switch off of the load voltage using an input signal in the controller.
• Block the valve control signal by locking the output signal with the "load voltage" input signal.
The power supply is via the 4-pin M12 plug è Fig. 1.
The power consumption depends on the type of valve terminal è Tab. 9 Calculate total power
consumption and "Pneumatics description, P.BE-CPV-...".
•When connecting the load voltage to pin 2, observe the tolerance 20.4 V DC … 26.4 V DC.
Check the load voltage of the valves during operation of the system.
•Protect the load voltage of the valve coils externally with a maximum 2 A fuse.

NOTICE
Avoid malfunctions caused by electromagnetic interference.
• Connect the earth potential to pin 4 of the power supply connector.
• Connect the earth connection of the end plate to the earth potential with low impedance.
• Use low-impedance connections to ensure that the product housing and the earth connection at
pin 4 have the same potential and that there are no compensating currents.

5.6 Prepare CPI system for commissioning
This section is only relevant if CPI/CP modules are connected to the CPI expansion port.
NOTICE
Addressing errors by changing address ranges during operation with different fieldbus systems.
• Do not connect a higher-order controller yet for preparation of commissioning the CPV master.
5.6.1 Check CP strings
Preparations
Before commissioning a CPV master with CPI extensions, every CPI system should first be separately
prepared for commissioning.
Proceed as follows:
1. Check the pneumatic tubing of the valve terminals using the manual overrides è Description of
pneumatics.
2. Check all electrical wiring of the CPI system.
3. Save the current string assignment of the CPI system as target assignment è 5.6.2 Save string
assignment.
5.6.2 Save string assignment
NOTICE
Addressing errors with accidentally incorrectly installed CPI modules.
If the string assignment of the CPI system is subsequently changed:
• After saving the string assignment, check the address allocations of the CPI system before starting
application programs.
