9604 1-11

The input modules process the input signals(e.g. from sensors) and transmit these signalsvia the field bus to the controller. The outputmodules are universal electrical outputs andcontrol small current-consuming devices withpositive logic, e.g. further valves, lights etc..

The pneumatic modules are used for thefollowing:• common channels for supply and exhaust air• electrical signals from all solenoid valve coils.

Work connections 2 and 4 are supplied for eachvalve location on the individual pneumatic modu-les.

By means of the common channels on thepneumatic end plate, the valves are suppliedwith compressed air and both the exhaust airand the pilot air from the valves are vented.Further modules for air supply are also available,in order that different work pressures can beused or in order that either MIDI/MAXI valves orISO valves can be fitted on a terminal.

Further information on their use is to be found inthe Pneumatics Manual for the valve terminal.Only the electronic modules and the node aredescribed here.

2.1 FITTING THE COMPONENTS

WARNINGBefore fitting the components switch off thefollowing:• the compressed air supply• the power supply for the outputs

(pin 2)• the power supply for the electronic

components (pin 1)

You thereby avoid:• uncontrolled movement of loose tubing• undesired movements of the connected

actuators• undefined switching states of the electronic

components.

CAUTIONThe valve terminal components contain partswhich can be damaged by electrostatic charges. • Do not therefore touch the contact surfaces

of the plug connectors at the side of themodules.

• Observe the instructions for dealing withcomponents liable to damage by electro-static charges.

You thereby avoid destroying the valve terminalcomponents.


9604 2-3

PLEASE NOTETreat all the modules and the components ofthe valve terminal with the utmost care. Payspecial attention to the following: • Screw connectors must not be twisted or subjected to mechanical stress.• The screws must fit accurately (otherwise

the threads will be damaged).• The specified torques must be observed.• The modules must be aligned correctly

(IP 65).• The contact surfaces must be clean (avoid

leakage and faulty contacts).• The contacts of the type 03 MIDI valve solenoid coils must not be bent (they

are not resistant to alternate bending and will break off if bent backwards).

In the case of modules and componentsordered at a later stage, observe also the fit-ting instructions included with the product.

Input/output modules

Before the valve terminal can be extended orconverted, it must first be dismantled.

Dismantling (see also following diagram)

• Remove completely the screws of the rele-vant modules. The modules are now heldtogether only by the electrical plug con-nectors.

• Pull the modules carefully and without tippingaway from the electrical plug connectors.

• Replace broken or damaged seals.


2-4 9604

Fitting (see also following diagram)

PLEASE NOTE• Always place the subsequently ordered modules after the last module before the end plate.• Do not fit more than 12 electronic modules.

Please note also the addressing limits of your field bus protocol.

Fit the modules as follows:• Fit a new seal on the right-hand contact sur-

face facing the node.• Fit the module as shown below.

Fastening screws max. 1 Nm

Fig. 2/1: Fitting electronic I/O modules


9604 2-5

End plates

A left-hand and a right-hand plate are requiredas mechanical termination of the modular termi-nal. These end plates fulfil the following functi-ons:• They comply with protection class IP 65.• They contain connections/contacts for the

protective earth cable.• They contain holes for fitting onto walls and

onto the hat rail clamping unit.

By means of screw connectors and the readyfitted spring contacts, the right-hand end plate ofthe ISO terminal is connected conductively to themanifold sub-bases. It is therefore sufficientlyearthed.

There are various designs of right-hand endplate for the terminls of type 03 (MIDI/MAXI).Each design is already fitted with a protectiveearth cable.

CAUTIONEarth the right-hand end plate with the pro-tective earth cable before fitting the terminaltype 03. You thereby avoid high voltages onthe metal surfaces in the case of a fault.


2-6 9604

Earth the end plates as follows:

• Right-hand end plate (type 03):To earth the right-hand end plate connect thecable fitted on the inside to the appropriatecontacts on the pneumatic modules or on thenode (see following diagram).

• Left-hand end plate (type 03 and type 05): The left-hand end plate is connected con-ductively to the other components via springcontacts which are already fitted.

Please note:Instructions on earthing the complete valveterminal are to be found in the chapter "Installa-tion".

Fitting the hat rail (type 03)

The terminal is suitable for fitting onto a hat rail(support rail as per EN 50022). For this purposethere is a guide groove on the rear of allmodules for hanging the terminal on the hat rail.

CAUTION• Hat rail fitting without the hat rail

clamping unit is not permitted.• If the terminal is fitted in a sloping position or at a point subjected to vibration,

protect the hat rail clamping unit against slipping and, by means of the screws (7),

against unintentional loosening/opening.

PLEASE NOTE• If the terminal is fitted in a horizontal position

without vibration, the screws (7) are not required for fastening the hat rail

clamping unit. • If your terminal does not have a hat rail

clamping unit, this can be ordered and fittedlater.

• The use of MIDI or MAXI clamping unitsdepends on the end plates fitted (MIDI/MAXI).

Proceed as follows:• Calculate the weight of your terminal (weigh

or estimate). General rule:• Make sure that the fastening surface can car-

ry this weight.

WARNINGBefore installation or maintenance work is car-ried out, the following must be switched off: • the compressed air supply• the power supply to the electronic

components (pin 1).• the power supply to the outputs/valves

(pin 2).

You thereby avoid:• uncontrolled movement of loose tubing• undesired movements of the connected


components.


9604 3-3

Selecting the field bus cable

A twisted, screened two-core cable must beused for the field bus cable. The cable types tobe used are specified in the PLC manual foryour controller. Take into account the distanceand the field bus baud rate set.

Selecting the operating voltage cable

Several parameters must be considered whenthe two operating voltages are connected.Further information can be found in the followingchapters:

• Chapter 3: InstallationSection: "Connecting the operating voltage"- Calculating the current consumption- Design of power unit- Cable cross section and length.

• Appendix A: Cable length and cross section- Determining the cross section and length by means of tables- Calculating with a formula.


3-4 9604

Connecting the cables to the plugs/sockets

CAUTIONThe position of the pins is different dependingon whether plugs or sockets are used.• The connections of the input and output

modules have been designed as sockets.• The connections of the field bus interface

and the operating voltage connections have been designed as plugs.

The pin assignment is to be found in the following chapters.

When you have selected suitable cables, con-nect them to the plugs/sockets according to thesequence of steps 1-7.

1. Open the plugs/sockets as follows(see diagram):

• Power supply socket:Insert the power supply socket into the operating voltage connection on the valve terminal. Unscrew the housing of the socket, then remove the connection part ofthe socket which is plugged into the operating voltage connection.

• Sensor plug and field bus socket: Unscrew the centre knurled nut.

4.1 BASIC PRINCIPLES OF CONFIGURATION AND ADDRESSING

General

Before commissioning or programming, firstcompile a configuration list of all connected fieldbus slaves. On the basis of this list you can:

• carry out a comparison between NOMINALand ACTUAL configurations in order toeliminate connection faults.

• access these specifications during the syntaxcheck of a program in order to avoidaddressing errors.

Configuration of the valve terminal requires avery accurate procedure, since different configu-ration specifications are required for each termi-nal on account of the modular structure. Pleasenote here the specifications in the sections whichfollow.


9604 4-3

Switching on the operating voltages

PLEASE NOTEObserve also the switching-on instructions inthe PLC manual for your controller.

When the controller is switched on, it automat-ically carries out a comparison between theNOMINAL and ACTUAL configurations. It isimportant here that:

• the specifications on the configuration arecomplete and correct

• the power supplies to the PLC and to the fieldbus slaves are switched on either simulta-neously or in the following sequence:

Please observe the following when switching onthe voltage supply:

• Common supply: If there is a common powersupply for the control system and all the fieldbus slaves, the power should be switched onvia a central switch or power unit.

• Separate supply: If the control system andthe field bus slaves have separate powersupplies, the power should be switched on inthe following sequence:

1. power supply to all the field bus slaves2. power supply to the control system


4-4 9604

Calculating the configuration data

Before configuring, calculate the exact number ofavailable inputs/outputs. A modular valve termi-nal consists of a different number of I/Os,depending on the type ordered.

PLEASE NOTE• The terminal makes available four status bits

for diagnosis via the field bus. These are automatically assigned within the terminalwhen there are input modules.

• The status bits occupy four extra input addresses.

The following table shows the I/Os required permodule for the configuration.

Module type Number of assigned I/Os *)

S valve sub-base (type 03)

D valve sub-base (type 03)

Address assignment of the valve terminal

The address assignment of the outputs of amodular valve terminal depends on theequipment fitted on the terminal. A distinctionmust be made between the following equipmentfitted:• valves and digital I/O modules• valves only• digital I/O modules only

PLEASE NOTEThe valve terminal may be fitted with a diff-erent number of inputs and outputs. Pleasenote therefore the manufacturer-specific confi-guration instructions in the following chaptersand check in the manual for your controllerhow such a fitting must be configured.

The basic rules described overleaf apply to theaddress assignment of these fitting variants.After the basic rules there is a detailed examplefor both type 03 and type 05 terminals.

PLEASE NOTEIf two addresses are assigned for one valvelocation, the following applies:• lower-value address ⇒

pilot solenoid 14• higher-value address ⇒

pilot solenoid 12


9604 4-9

Basic rule 1

The address assignment of the valves, of thedigital I/O modules and of the status bits is takeninto account with mixed fittings.

1. Outputs The address assignment of the outputs does not depend on the inputs.

1.1 Address assignment of the valves• Addresses should be assigned

in ascending order without gaps. • Counting must be from left to right .• Single sub-bases always

occupy 2 addresses.• Double sub-bases always

occupy 4 addresses. • ISO valve locations always

occupy 2 addresses. • Maximum 26 valve solenoid

coils can be addressed.1.2 Rounding up to 4 bits: different cases

a) If the number of addresses can be divided evenly by 4, continue with section 1.3.

b) If the number of addresses cannot bedivided evenly by 4, the number mustbe rounded up to 4. The rounded 2 bits in the address range cannot be used.

1.3 Address assignment of output modules:After the valves (rounded to 4-bits), the digital outputs are addressed• Addresses should be assigned

in ascending order without gaps.• Counting must be from right to left .• Counting on the individual modules

is from top to bottom.• Digital output modules always

occupy 4 addresses.


4-10 9604

PLEASE NOTEThe field bus protocol permits maximum32 outputs (including valve coils).

2. InputsThe address assignment of the inputs doesnot depend on the outputs.

2.1 Addressing the input modules• Addresses should be assigned

in ascending order without gaps.• Counting on the node is

from right to left .• Counting on the individual modules

is from top to bottom.• 4-input modules occupy 4 addresses.• 8-input modules occupy 8 addresses.

2.2 Status bitsThe status bits are transferred to the four highest-value positions of the configured address area (28, ..., 31).

PLEASE NOTE The field bus protocol permits up to 32 inputs(28 digital inputs and 4 status bits).


9604 4-11

When the power supply is switched on, the valveterminal recognizes all available pneumatic modules(type 03: max.13 modules; type 05: 4,8,12 valvelocations) and digital input/output modules automat-ically and assigns the appropriate addresses. If avalve location is not used (blanking plate) or if a digitalinput/output is not connected, the appropriate addressis nevertheless assigned. The diagram below showsthe address assignment with mixed fitting.

Remarks on diagram• If single solenoid valves are fitted onto

double sub-bases, four addresses will be as-signed for valve solenoid coils.The higher ad-dress remains unused (see address 3).

• If unused locations are sealed with blankingplates, the addresses will still be assigned(see addresses 12, 13).

• Due to the 4-bit orientated addressing of thevalve terminal, the address of the last loca-tion is always rounded up to the full 4 bits(unless all 4 bits are already used). Two ad-dresses cannot therefore be used (see ad-dresses 14, 15).

Fig. 4/4: Address assignment of a valve terminal with digital I/Os (e.g.type 03)


4-12 9604

Basic rule 2

If only valves are used, the address assignmentwill be as described in basic rule 1.

PLEASE NOTE• Maximum 26 valve solenoid coils can be

addressed.• Rounding of the last two positions

on the valve side is not necessary.• Valve terminals without input modules

do not require a configuration for the inputs.The status bits are not therefore available.

Basic rule 3

If only electrical I/Os are used, the addressassignment will be as described in basic rule 1.

PLEASE NOTE• Counting begins immediately to

the left of the node.• Rounding of the last two positions

on the valve side is not necessary.• With all locations fitted, the terminal

has 32 inputs (28 digital inputs and 4 statusbits) or 32 digital outputs.

Address assignment after extension/conversion

A special feature of the modular valve terminalis its flexibility. If the demands placed on themachine change, the equipment fitted on theterminal can be modified accordingly.

CAUTIONIf the terminal is extended or converted at alater stage, there may be a shifting of theinput/output addresses. This applies in thefollowing cases:• If one or more pneumatic modules are

added or removed at a later stage (type 03).• If a pneumatic module with single valves

is replaced by a new module with double valves or vice versa (type 03).

• If additional input/output modules are inserted between the node and existing input/output modules.

• If existing 4-input modules are replaced by 8-input modules or vice versa.

If the configuration of the inputs is modified, theaddresses of the status bits will always beshifted.

The diagram below shows an extension to thestandard fitting of the previous diagram andshows the modifications which must be made tothe address assignment.

Testing the valves

WARNING Switch off the compressed air supply beforetesting the valves.

You thereby avoid undesired or dangerousmovement of the actuators.

CAUTION• This test function runs automatically within

the terminal. All valves are switched on andoff cyclically.

• None of the programmed locking or switch-ing conditions will be taken into account.

The valve terminal has a built-in test function forvalves, which can be activated even when the fibre-optical waveguide bus is not connected.

This function is switched on with the upperswitch element of the operating mode switch.This switch is visible on the right-hand printedcircuit board when the node cover is lifted (seealso Chapter 3.2)


9604 5-9

Starting the test routine

1. Switch off the power supplies (pins 1 and 2).

2. Open the node.

3. Set DIL switch element 1 at OFF.

4. Switch on the power supplies (pins 1 and 2).

5. Start: Set DIL switch element 1 at ON within5 seconds *).

*) Otherwise the valve terminal will assumenormal operation after the waiting period.

During the self-test, the valve terminal firstswitches all valves on and off simultaneouslyseveral times. Then the valves in each group ofeight are switched on and off once individually.

Stopping the test routine

1. Switch off the power supplies (pins 1 and 2)of the terminal.

2. Bring the address selector switch and the DILswitch elements into their original positions.

Please noteFor normal fibre-optical waveguide operation, thetop DIL switch must be switched on (seeChapter 3.2, Setting the operating mode). Other-wise malfunctioning will occur when the opera-ting voltage is switched on, particularly when thecontrol system and the valve terminal have acommon power supply (see Chapter 4.1, Swit-ching on the operating voltages).


5-10 9604

5.3 DIAGNOSIS VIA FIELD BUS

The modular valve terminal offers the followingpossibility for diagnosis via the field bus:

• four status bits

The four status bits are interrogated like normalinputs. The contents are coded and contain thefollowing information:

Status bits

The status bits are configured like inputs andalways occupy the four highest-value ad-dresses of the available address range (bits 28 ... 31). If the inputs of the addressesthereunder are not used, the terminal will setthem at "logic zero".

The diagnostic information of the four status bitsis coded and contains the following meaning:

Diagnostic information

Coded individual message:

• short circuit/overload of outputs

• operating voltage pin 2 below 21.6 V (Vval)

• operating voltage pin 2 below 10 V (Vout)

• supply to inputs (sensors) under 10 V (Vinp)

If faults occur on the II/O buse.g. due to failure of the fieldbus signal or interruption to thefibre-optical waveguide, all outputs (valvesand additional outputs) will beswitched off after 100 ms.

If the control system switchesto STOP, all outputs (valvesand electrical outputs) on thevalve terminal will beswitched off.

Please note:

Short-circuit/overload at an output module

If there is a short circuit or overload:

• the digital output will be switched off

• the red LED will light up

• the error code "short circuit/overload" will beentered in the four status bits

In order to reactivate the output, proceed asfollows:

The output can then be reset at 1. If the shortcircuit still exists, the output will be switched offagain.

Step Explanation

Eliminate short circuit or overload

Set output at 0 (RESET) User-program controlled in the PLCprogramThe error bit in the status bits of theterminal is reset at logic 0.

CABLE LENGTH AND CROSS SECTION

PLEASE NOTEThe following information assumes that thefacts quoted in the Chapters "Installation" ofthis manual are already known and is to beused exclusively by personnel with thenecessary training in electrotechnology.

A load-dependent voltage drop occurs on allthree cables for the operating voltage supply ofa valve terminal. This can cause the voltage atpin 1 or pin 2 of the operating voltage connecti-on to lie outside the permitted tolerance.

Recommendation

• Avoid long distances between the power unitand the terminal.

• Calculate the suitable length and cross sec-tion of cable in accordance with the followinggraphs or formulae. Please note that:– the graphs supply approximate values for

the cross sections 1.5 and 2.5 mm2.– the formulae supply exact values for all

cross sections.

PLEASE NOTEThe following graphs and formulae assumethat the cross sections of the operating volt-age cables (pins 1, 2 and 3) are the same.


9604 A-7

Calculating with a graph

Proceed as follows:

1. Calculate the maximum current consumptionof the outputs/valves (I2).

2. Calculate the lowest voltage (VOmin) to be ex-pected on the power unit during operation.Take into account here:• the load dependency of the power unit• the fluctuations in the primary power

voltage

3. Read in the table for your cross-section thepermitted cable length.Example for 1.5 mm2:VOmin = 22.8 V, I2 = 2 A; Lmax = 25 m

Calculating with a formula

Proceed as follows:

1. Calculate the maximum current consumptionof the inputs and electronic components (I1)as well as of the outputs/valves (I2).

2. Calculate the lowest voltage (VOmin) to be ex-pected on the power unit during operation.Take into account here:• the load dependency of the power unit• the fluctuations in the primary power

voltage

3. Enter the values in the appropriate formula.The equivalent circuit diagram and theexample explain the correlation.

Formula for cable length

L ≤ (VOmin − VTERMINALmin) ⋅ A ⋅ κCu

2 ⋅ I2 + I1

This means:

• VTERMINAL = 24 V ± 10%, minimum: VTERMINALmin ≥ 21.6 V

• VOmin = minimum operating voltagesupply (at power unit)

• Current I1 = current for electronic componentsand inputs

• Current I2 = current for outputs/valves

• A = cable cross section (uniform e.g. 1.5 mm2)

• k = conductance value of cables

(uniform e.g. κCu = 56 m

mm 2 ⋅ Ω )

Example: I1 = 1 A; I2 = 5 A; VO = 24 V; VTERMINALmin = 21.6 V ;

κCu = 56 m

mm 2 ⋅ Ω;

Result of example:L ≤ 18 m for A = 1.5 mm2

L ≤ 30 m for A = 2.5 mm2

GLOSSARY

VIFB7 - 03/05 Appendix B

9604 B-1

Address selector switch

(see also field bus address) The field bus address of the terminal is set onthe address selector switches in the field busnode of the valve terminal.

Baud rate

The baud rate specifies the speed of datatransmission. The unit of data transmissionspeed is 1 baud = 1 bit/s. In all systems, thesender and the receiver must be set at the samebaud rate, otherwise there will be errors intransmission.

Bus topology

The maximum distance between 2 valve termi-nals/valve sensor terminals is 45 m. In order thatthe maximum number of terminals can beconnected to the II/O bus over maximumdistances, we recommend the following bustopology.You should arrange your slaves on the bus sothat a "quasi ring" is made.To do this connect terminal no. 1 directly toterminal no. 3, and connect this to terminal no.5. Then connect the "quasi ring" back to terminalno. 4, then to terminal no. 2.From terminal no. 2 connect the fibre-opticalcable to the field bus module.

Diagnostic byte

The diagnostic byte supplies important informati-on on the status of the valve terminal whenerrors occur. Diagnostic bytes are interrogatedby the user program of the PLC via the field bus.The status information thus acquired can beevaluated with software. Errors can be shown inclear text on the screen.

Exhaust air

Compressed air which escapes into the atmos-phere from a pneumatic device. With valveterminals the exhaust escapes through a com-mon channel. The flow rates must be sufficentand, with centrally ducted systems, non-returnvalves must be supplied for decoupling.

Fibre-optical waveguide

A fibre-optical waveguide transmits light signals.Fibre-glass and fibre-plastic are used as fibreoptical waveguides. Depending on the quality ofthe fibres, an optical waveguide can transmitsignals over a distance of several metres or upto several kilometres. This transmission process is immune to interfe-rence.

E

F


9604 B-5

In order to guarantee reliable data transmission,a suitable plug connection must be establishedbetween the fibre-optical waveguide and thevalve terminal. The following plug is suitable forthis purpose:type F-TNC (for 5.5 - 6 mm cable with 1 mmpolymer fibres).

Installation instructions1.Remove about 18 mm of the cable

sleeve with a cable stripping knife.Shorten the strain relief braiding (Kevlar) by about 7 mm. Removeabout 7 mm of the insulation from the fibre covering of the cable with a 1 mm precision insulation stripper.

2.Push the screw connector, washer,seal and cutting ring over the cablesleeve. Then push the clamping discover the fibre coating.

3.Push the guide pin as far as it willgo onto the fibre. To fix it in this position, press the clip above thecable sleeve into the guide pin. The fibre should project about 1 mm out of the guide pin when the cable isfully inserted.

4.With the aid of a grinding/polishingblock, grind down the fibre end surface to a length of about 5.5 mmon abrasive paper (600-1000 grain) on a hard base, e.g. glass plate.

5.For final fitting, clamp the strain relief braiding between the clampingdisc and the cutting ring. Push theseal, washer and screw connector forward to the cutting ring. Place theplug housing over the guide pin, clamping disc, cutting ring, seal andwasher and tighten the screw connector. The strain relief braidingwill then be fastened between the cutting ring and the clamping disc. The cable sleeve will also be sealedagainst the plug body by the seal ring. Cut off the axcess braiding.
