1. Summary of components
The input modules control the processing of input signals
(e.g. from sensors) and pass these signals onto the controller
via the field bus.
The output modules are universal electric outputs and control
low-current consuming devices, e.g. further valves, bulbs,
etc.
Additional I/O modules for special applications are also available.
Further information on the use of all the I/O modules can be
found in the ”Supplementary manual for the I/O modules” for
your valve terminal.
The pneumatic modules provide the following:
– the common channels for the supply and exhaust air
1-8
– electric signals from all valve solenoid coils
Work connections 2 and 4 have been provided for each valve
location on the individual pneumatic modules.
The valves are supplied with compressed air via the common
channels on the pneumatic end plate or via special supply
modules. The exhaust air and pilot exhaust air are also
vented via these channels or modules. Further modules for
supplying pressure are also available, e.g. to enable you to
work with different working pressures.
Detailed information on the use of these modules can be
found in the ”Pneumatics manual” foryourvalveterminal.

3.1Installation summary
3.1.1 System structure on the remote bus
The multi-functional valve terminal type 03 with FB21 is an
optical fibre waveguide remote bus slave on the INTERBUS
with Rugged-Line connection technology. The terminal behaves on the remote bus like an optical fibre waveguide bus
terminal with integrated I/Os and must be addressed accordingly.
Please note
– Commissioning on the remote bus can only take place
when all the slaves have been fully connected.
– The valve terminal requires 24 V DC power supply. This
is supplied via the Rugged-Line plug. A separate supply
and separate switch off for the valve terminal outputs/
valves is possible.

Potential equalization
The valve terminal has two ear th connections for potential
equalization:
– on the load voltage connection
– on the left-hand end plate (M4-thread)
Please note
S Always connect the earth potential to pin 5 of the power
supply connection.
S Connect the earth connection of the left-hand end plate
to the earth potential with low impedance (short cable
with large cross-sectional area).
S 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 equalization currents.
In this way you can avoid faults caused by electromagnetic
influences and comply with electromagnetic compatibility
in accordance with the EMC guidelines.

– the load voltage of the outputs/valves must be protected
with an external fuse maximum T10 A against short circuit/overload.
– the power supply for the electronics/inputs must be pro-
tected with an external fuse 3.15 A against short circuit/
overload (recommended).
– the power supply for the sensors is additionally protected
with the built-in fuse (2 A).
– the common tolerance of 24 V DC
¦ 10 % must be ob-
served.
– both connections for potential equalization are connected
and that equalizing currents are prevented.
– the load voltage at pin 3 (valves/electric outputs) can be
switched off separately.

4.1.3 Address assignment of the valve terminal
The address assignment of the outputs of a multi-functional
valve terminal depends on the modules/valves fitted on the
terminal. A distinction must be made between the following
fitting variants:
– valves and digital I/O modules
– only valves
– only digital I/O modules
The basic rules described below apply to the address assignment of these fitting variants. A detailed example is given
after these basic rules.
Please note
If two addresses are assigned for one valve location, the
following assignment applies:
lower-value address > pilot solenoid 14
higher-value address > pilot solenoid 12

Festo P.BE-VIFB21-03-EN en 0010a
4. Commissioning
Basic rule for addressing
With mixed fitting, consideration is given to the address assignment of the valves, the digital I/O modules and the
status bits.
Outputs
1. The address assignment of the outputs does not depend
on the inputs.
2. Address assignment of the valves:
– Addresses are assigned in ascending order
without gaps
– Counting begins on the node from left to right.
– Maximum 26 valve solenoid coils can be addressed
– Single manifolds always occupy 2 addresses.
– Double manifolds always occupy 4 addresses.
3. Rounding up to 4 bits: case distinction:
a) If the number of valve addresses is divisible by 4
without remainder, continue with point 4.
b) If the number of valve addresses is not divisible by
4 without remainder, you must round the addresses
up to 4 because of the 4-bit orientated addressing.
The bit thus rounded up in the address range cannot
be used.
Festo P.BE-VIFB21-03-EN en 0010a
4. Address assignment of the outputs:
The digital outputs are addressed after the (rounded up
4-bit) addresses of the valves.
– Addresses are assigned in ascending order without
gaps.
– Counting begins on the node from right to left.
– Counting on the individual modules is from the top to
the bottom.
– Digital output modules occupy 4 or 8 addresses.

Inputs
1. The address assignment of the inputs does not depend
on the outputs.
2. Address assignment of the inputs:
– Addresses are assigned in ascending order without
gaps.
– Counting begins on the node from right to left.
– Counting on the individual modules is from the top to
the bottom.
– Input modules occupy 4, 8, 12 or 16 addresses.
3. Status bits:
The address assignment of the status bits depends on
the fitting variants of the inputs and on the configuration.
The following basic rule applies:
– The status bits are only available if input modules are
connected to the terminal and configured.
– Addressing:
The status bits are transferred to the four highestvalue positions in the configured address range.

When the power supply is switched on, the valve terminal
recognizes all available pneumatic modules and digital input/
output modules automatically and assigns the appropriate
addresses. If a valve location remains unused (blanking

address will still be assigned. The diagram below shows an
example of address assignment.

the higher address will in each case remain unused (see
address 3).

– If unused valve locations are sealed with blanking plates,
the addresses will still be assigned (see addresses 12,
13).
– Due to the 4-bit orientated addressing of the modular
valve terminal, the last valve location will always be
rounded up to a full 4 bits (providing the fittings do not
already use the full four bits). Two addresses cannot,
therefore, always be used (see addresses 14, 15).
Additional instructions for valve terminal without I/O modules
If only valves are used, the address assignment will always
be as described in basic rule for addressing.
Please note
– Maximum 26 valve solenoid coils can be addressed.
– There is no rounding of the last two positions on the
valve side.
– Valve terminals without input modules do not require a
configuration for inputs. The status bits are not therefore available.

4.1.4 Address assignments after extension/conversion
A speciality of the multi-functional valve terminal is its flexibility. If the demands placed on the machine change, different equipment can be fitted onto the valve terminal.
Caution
If the terminal is extended or converted at a later date, the
input/output addresses may be shifted. This applies in the
following cases:
– When one or more pneumatic modules are added or
removed at a later date.
– When a pneumatic module with single-solenoid valves is
replaced by a new module with double-solenoid valves
or vice versa.
– When additional input/output modules are added be-
tween the node and exsting input/output modules.
– Existing input/output modules are removed or replaced
by input/output modules which occopy more fewer
input/output addresses.

If the configuration of the inputs is modified, the addresses
of the status bits will be shifted.

4.2.4 Addressing the inputs and outputs
Further information on addressing can be found in the manuals for your controller and the INTERBUS module.
The address assignment (process data assignment) of the
inputs and outputs of a valve terminal on the INTERBUS or a
compatible system depends primarily on the INTERBUS module and on the control system used.
Caution
There are different address assignments on the INTERBUS.
The reason for this is the assignment of the process data
within the INTERBUS module and not within the Festo
valve terminal.
S When assigning the addresses, note the position of the
high and low bytes, because in conjunction with some
control systems the position of these bytes can be
swapped.
Festo P.BE-VIFB21-03-EN en 0010a
In this way you will avoid faults when addressing the inputs/
outputs.
4-27
4. Commissioning
The following examples explain the different address assignments and the position of the low bytes (n) and the high
bytes (n+1). A distinction is made between the:
– Siemens mode and the
– standard mode.
Example:
– In Siemens mode, the lower-value output byte (byte n) is
mapped on valve coils 0 - 7 of the valve terminal; byte
n+1 on the next coils (8 -15) etc.
– In standard mode, the lower-value output byte (byte n) is
mapped on valve coils 8 -15 of the valve terminal; byte
n+1 on valve coils 0 -7.
In the chapter after the following examples, you will find instructions on addressing with the CMD software (process
data assignment) and on modifying the position of the low
and high bytes (”Byte swap”).

4.2.5 Entering process data via the CMD software
The CMD software offers, as from version 4, the possibility of
assigning each input/output of a valve terminal within the
configured address range to any input/output in the PLC/IPC.
To do this, proceed as follows:
SAdd a valve terminal to your bus structure (necessary
steps see section 4.2.2 ”Configuring the bus with CMD
software”).

In the following dialogue window you can determine the I/O
addresses. In this way you can adapt the I/Os of your valve
terminal to the PLC used. If necessary, swap the high byte
and low byte (byte swap). The following mapping shows the
byte-by-byte assignment for a Siemens S5.

Please note
In order to correct the byte swap, it will suffice if you assign the appropriate I/O address to each byte.
An individual I/O assignment at bit level is only necessary
in very few cases.
The following dialogue window shows you the entries which
are necessary for swapping the assignment of the high byte
and the low byte (example: byte swap for ”standard mode”).

4.2.6 Status bits
The status bits of a valve terminal serve for displaying internal valve terminal faults, e.g.:
– voltage below tolerance
– voltage switched off
– short circuit or overload
These error messages are treated like inputs and transmitted
with the rest of the inputs of a valve terminal to the INTERBUS master. There they can be interrogated, linked and processed as ”normal” inputs.
Further information on the function of the status bits can be
found in the secton ”Diagnosis via the INTERBUS” in chapter
5.3.
The status bits always occupy four addresses of the configured address range. If the inputs of the input addresses
thereunder are not used, the valve terminal will set them to
”logical zero.” The addresses of the status bits in the address
range of a valve terminal depend, like all inputs/outputs, on
the INTERBUS modue and on the control system used.

Preprocessing
Under preprocessing on the INTERBUS, we understand the
logical linking of process data within the INTERBUS module.
Please note
All inputs/outputs of a module can be preprocessed (see
manual for CMD software from Phoenix Contact).
Periphery faults (PF)
If a fault is detected by the valve terminal and entered in the
statusbits,aaperipheryfaultwillalsobetriggered and
transmitted to the INTERBUS module, where it will be displayed.
The reasons for periphery faults can be:
4-36
1. The voltage of the valves and electric outputs is below
the tolerance (21.6 V).
2. The voltage for the valves and electric outputs is switched
off (e.g. EMERGERNCY STOP).
3. The power supply for the inputs/sensors is switched off
(e.g. internal fuse triggered).
4. There is a short circuit or overload at the digital outputs.

Masking out an error message (up till INTERBUS
G3 module)
When delivered from the factory, the periphery fault of a valve
terminal can be triggered by all four causes (summary of periphery faults see chapter 5.3 ”Diagnosis via INTERBUS”).
However, the fault can be partially suppressed if DIL switch 2
inside the node is switched on (compare the section ”Setting
the DIL switch elements” in chapter 3.2.2):
– DILswitchelement2toON:
error causes 1 and 2. (tolerance of valve/output voltage
and EMERGENCY STOP) are not transmitted, but suppressed. Only causes 3 and 4 are transmitted.
Please note
Error causes 1 and 2 a re entered in the status bits irrespective of the setting of DIL switch 2.
Festo P.BE-VIFB21-03-EN en 0010a
– DILswitchelement2toOFF(factorysetting):
All error causes will be transmitted as periphery faults to
the INTERBUS.
The system is not stopped by periphery faults. You can determine the reaction to periphery faults by parametrizing the
INTERBUS module. You can also quit the periphery fault by
parametrizing the INTERBUS module.

Masking out an error message (as from INTERBUS
G4 module)
As from the INTERBUS G4 module, error messages can be
displayed or masked out by means of the CM D software
(SRC services) (summary of the periphery faults see the section ”Diagnosis via INTERBUS” in chapter 5.3).
Proceed as follows:
1. Open the dialogue window ”Activity/service editor” in the
CMD software
2. Select the entry ”Set valve request” in the list field”Name.”
3. Enter the appropriate code in the 4-th field in the table.
Code 046C: error message US2 1 is masked out
Code 047C: All errors are shown
Code 0404: No error is shown
Code 0004: G4-compatible mode

Please note
The setting applies to the complete bus with all bus slaves.
