23 1. Installation 1.3 Connecting to the field bus Field bus cable Please note If installation has not been carried out correctly and if high baud rates are used, data transmission errors may occur as a result of signal reflections and attenuations. Causes of the transmission faults may be: missing or incorrect terminating resistor incorrect screening/shield connection branches transmission over long distances unsuitable cables. Observe the cable specifications. Refer to your controller manual for information on the type of cable to be used. Please note If the valve terminal is fitted into a moving part of a machine, the field bus cable on the moving part must be provided with strain relief. Please observe also the relevant regulations in EN part

24 1. Installation Use a twisted screened 2 core cable for the field bus in accordance with PROFIBUS specifications (EN 50170, cable type A): Surge impedance: ( MHz) Capacitance per unit length: < 30 nf/km Loop resistance: < 110 /km Core diameter: > 0.64 mm Core cross sectional area: > 0.34 mm 2 Bus length Exact specifications on the bus length can be found in the next section and in the manuals for your control system Field bus baud rate and field bus length Please note The maximum permitted field bus segment lengths depend on the baud rate used. Note the maximum permitted segment length (cable length without repeater), if you connect the SFC DC to a field bus segment. Avoid branch lines. The valve terminal sets itself automatically to one of the following baud rates: Baud rate Maximum segment length 9.6; 19.2; kbaud 1200 m kbaud 1000 m 500 kbaud 400 m 1500 kbaud 200 m kbaud 100 m Tab. 1/4: Maximum field bus segment lengthsfor PROFIBUS DP depending on the baud rate 1 10

Tab. 1/6: Calculating the current consumption 1 14

29 1. Installation Selecting the cable Calculate the necessary cross sectional area and the maximum permitted cable length. Avoid long distances between the power unit and the valve terminal. Long cables reduce the voltage supplied by the power unit Selecting the power unit Warning For the power supply use only PELV circuits as per IEC/DIN EN (Protective Extra Low Voltage, PELV). Take into account also the general requirements for PELV circuits as per IEC/DIN EN Use only power packswhich guarantee reliable electrical isolation of the operating voltage as per IEC/DIN EN By the use of PELV power units, protection against electric shock (protection against direct and indirect contact) is guar anteed in accordance with IEC/DIN EN (electrical equipment of machines, general requirements). The current requirement of a CP system depends on the number of CP modules and valve coils. Recommendation: Use closed loop controlled power units. When selecting the power unit, check that it provides sufficient output. Calculate the total current requirement in accordance with section

30 1. Installation Connect the power supply of the valve terminal Please note Use only a socket in accordance with appendix A.2 for the power supply and connect this only to the connection for the power supply (see Fig. 1/1).

However, the electrical isolation will then no longer be effective (see Fig. 1/6). 1 16

31 1. Installation 1 Cable 2 Strain relief 3 Housing 4 Connecting part Fitting the connector socket Fig. 1/4: Preparing Individual parts of plug and cable exit When you have selected suitable cables, connect them as follows (Fig. 1/4): 1. In order to open the plug, loosen the centre knurled nut. 2. Open the strain relief on the rear part of the housing. Then pass the cable through. 3. Remove 5 mm of insulation from the end of the cable and fit end sleeves on the strands. 4. Connect the ends of the conductors. 5. Replace the connector part on the housing of the socket. Pull the cable back so that there are no loops inside the housing. 6. Tighten the strain relief. 1 17

32 1. Installation Observe the following when connecting the 24 V load voltage (pin 2): Observe the tolerance ( V DC). Check the 24 V load voltage of the valves while the system is operating. Caution Excessive voltages or short circuits can lead to functional damage to the CP... SC DP, whereby actuators can no longer be controlled. Protect the load voltage of the valve coils with external fuses. In order to ascertain the size of the fuses, calculate first the maximum current consumption in accordance with section Please note Check your emergency stop circuit, in order to ascertain the measures necessary for switching your machine/sys tem into a safe state in the event of an emergency stop. Switching off the load voltage for the valves and output modules in the secondary circuit of the power unit. Switching off the compressed air supply for the valve terminal. Due to energy stored in the input circuitry of valve ter minals, there may be a delayed reaction of the valves when the load voltage is switched off. Take this into consideration, e.g. as follows: by using an input signal in the controller for checking whether the load voltage has been switched off. by blocking the control signal for the valves by locking the output signal with the input signal Load voltage". 1 18

33 1. Installation Potential equalization Earth the valve terminal: at the power supply connection (pin 5) and at the earth connection of the housing (see Fig. 1/1). Please note By means of low impedance connections, make sure that the housing of the valve terminal and the earth connection at pin 5 have the same potential and that there are no equalizing currents. In this way, you will avoid interference caused by electro magnetic influences. 1 19

SC DP via the CP extension connection. 1 1 CP extension connection Fig. 1/7: CP extension connection on the CPA SC DP Proceed as follows 1. Connect the modules to the extension connection. 2. Start the automatic recognition process with DIL switch element 1 (see section 1.2.3). Please note The rules for CPI systems also apply for extending the CP... SC DP (see section 1.6.1). You can connect the following CPI/CP modules to the CP extension connection: CP input and output modules CPI input and output modules (with extended functions) 1 22

37 1. Installation CPV SC with CPI connection CPV/CPA valve terminals with and without extended functions. Caution The maximum cable length between rhe CP... SC DP and the last CP module must not exceed 10 m. The CP connecting cables must have special electrical properties. Always use, therefore, Festo CP connecting cables. Ready to use CP connecting cables are available from Festo. These are available in various lengths and designs. Recommendation Use blanking plugs for sealing unused connections. 1 23

38 1. Installation Rules for extending the CPI system The CPI system supports a different number of modules per CP string, depending on the type of CP master and on the CPI/CP modules connected. The CP... SC DP is a CPI master. Modules can be placed in two different groups: CPI modules (with extended functions) CP modules (without extended functions). CPI system 1) Rules Master Input modules, output modules, valve terminals with CPI connection Maximum 4 modules on the CP string Max. 32 I and 32 O (per CP string) The sequence of the modules within the CP string is optional A mixture of CPI modules is possible on CPI masters: Only one CP input module is possible at the end of each CP string Only one CP valve terminal 2) or one CP output module 2) is possible per CP string.

43 2. Commissioning 2.1 Preparing the valve terminal for commissioning Switching on the operating voltages Please note Please observe the switching on instructions in the manual for your controller. Before switching on, make sure that the field bus has been configured completely and correctly as specified. Recommendation: Providing the safety concept of your machine/system permits this, commission the CP... SC DP at first with both supply volt ages (pins 1 and 2), but without compressed air. A suitable test function is therefore available which does not trigger undesired reactions. Please observe the following when switching on the power supply: Common supply Separate supply Common power supply for the control system and all field bus slaves via a central power unit or a central switch. If the control system and the field bus slaves have separate power supplies, the devices must be switched on in the following sequence: 1. the operating voltage supply for all field bus slaves 2. the operating voltage supply for the controller. 2 3

44 2. Commissioning Address assignment CPA SC DP The CPA SC DP valve terminal always occupies 32 output addresses, irrespective of the number of valve solenoid coils fitted. This enables the valve terminal to be extended at a later date without the need to shift the addresses. Please note As the CPA SC DP always occupies 32 addresses, the next free address in the CP extension is 32. Depending on the configuration (number of valve loca tions and internal cabling), a valve location supports the control of one or two solenoid coils. Accordingly, the valve locations occupy one or two addresses, irrespective of whether the valve location is fitted with a valve plate or a blanking plate. The internal circuitry cannot be modified at a later stage. The following diagram shows how many solenoid coils can be controlled on the individual valve locations. Pos = number of the valve location Coils = total number of valve solenoid coils light grey = 1 valve coil dark grey = 2 valve coils Fig. 2/1: Address assignment on the CPA SC DP 2 4

45 2. Commissioning If a valve location for 2 addresses is actually equipped with two solenoid coils, the following allocation applies: pilot solenoid coil 14 occupies the less significant address pilot solenoid coil 12 occupies the more significant address. If a valve location for two addresses is fitted with only one solenoid coil, the more significant address will remain unused. However, the valve location still occupies two addresses. Address assignment of the valve coils on the CPA SC DP is from left to right and on the individual valve locations from the front to the rear. Example in the following diagram. The first 8 valve locations support control of two solenoid coils each. ab ad ab Manual overrides and LEDs for the solenoid coils 12 ad Manual overrides and LEDs for the solenoid coils 14 Fig. 2/2: Addressing example on the CPA SC DP (with 24 valve locations) 2 5

46 2. Commissioning Address assignment CPV SC DP The valve terminal type CPV SC DP always occupies 16 out put addresses, irrespective of the number of valve solenoid coils fitted. This enables the valve terminal to be extended at a later date without the need to shift the addresses. Please note As the CPV SC DP always occupies 16 addresses, the next free address in the CP extension is Single solenoid valves occupy one valve location 2 Double solenoid valves occupy two valve locations Fig. 2/3: Address assignment on the CPV SC DP If a valve location for 2 addresses is actually equipped with two solenoid coils, the following allocation applies: pilot solenoid coil 14 occupies the less significant address pilot solenoid coil 12 occupies the more significant address. 2 6
