Intended use
The CPXFB33, CPXMFB34 and CPXMFB35 bus nodes
documented in this manual are intended only for use as
stations (I/O device) on the industrial Ethernet system
PROFINET IO.
The bus nodes can be used in three different operating
modes:

Remote I/O

Remote controller

Remote I/O with additional function Prioritized Startup,

also designated "Fast Startup" (FSU)

The FSU operating mode ensures a faster startup of the CPX

system.
But this operating mode has restrictions regarding
commissioning and parametrisation. Detailed information can
be found in the corresponding chapters.
The CPX terminal must only be used as follows:

As intended in an industrial environment

In original condition without modification (only the

conversions or modifications described in the
documentation supplied with the product are permitted)

In faultless technical condition

The limit values specified for pressures, temperatures,

electrical data, torques etc. should be observed.

Setting the diagnostics mode with DIL switch 2 (in remote I/O operating mode)

Festo P.BECPXPN IOEN en 1008b

1. Installation

Note
(1) Diagnostics mode reduces the available address space
Use of the diagnostics mode (status bits or I/O diagnostic
interface) occupies 8 I or 16 I/O bits and thus reduces the
number of I/O bits which are available for module
communication. In this way, the number of addressable
modules is reduced in favour of additional status or
diagnostic information.
Take account of this fact for the planning of your
CPXterminal.
(2) Subsequent activation changes configuration
During subsequent activation of the diagnostics module
(status bits or I/O diagnostics interface), the CPXinternal
I/O image can be displaced.
The system controller carries out this adjustment
automatically. Manual manipulation, e.g. a reconfiguration
of the CPX terminal or manual adaptation of the hardware
and network configuration are not required.
Assignment of the I/O addresses and diagnostics
addresses can be changed as needed.
To do this, repeat the hardware and network configuration
in your configuration and programming software
(e.g. Siemens SIMATIC STEP 7), especially assignment
ofthe inputs and outputs (see section 2.7.1 and
section 2.7.2).

Use of the memory card

The memory card is used as a carrier of configuration data,
e.g. of the fieldbus device name (PROFINET IO device name),
and thus simplifies bus node replacement.

Note
Data stored on the card have priority over other
configuration data which are stored, e.g. in the bus node
memory or in the controller system (see also section 2.8.1,
sequence of the start parametrisation with memory card).

Caution
Risk of malfunctions or damage.
Inserting or removing the memory card while the power
supply is switched on can result in malfunctions of or
damage to the memory card.
Disconnect the power supply before you insert or

remove the memory card.

Replacement
of the memory card

Replacement of the bus node

Easy replacement using memory card
The memory card is used as a carrier of configuration data,
e.g. of the fieldbus device name, i.e. of the PROFINET IO
device name. Thus, a bus node can be conveniently replaced.

Note
Check the startup behaviour of the CPX terminal before
replacing the bus node.
If the Modify LED (M) lights up or flashes permanently
after the system start, System start with saved
parametrisation and saved CPX expansion" is set or
Force" is active.
For CPX terminals with a permanently lit or flashing MLED,
the parametrisation at replacement of the bus node or
CPX terminal during servicing is not automatically created
by the higherlevel system.
In this case, verify which settings are required before
replacement, and restore these settings after replacement.

Caution
Risk of malfunctions or damage.
Inserting or removing the memory card while the power
supply is switched on can result in malfunctions of or
damage to the memory card.
Disconnect the power supply before you insert or

remove the memory card.

1. Installation

Use of switches and routers

The switch integrated in the bus node permits division of the
network into several segments.
With use of additional switches and routers, the network can
be divided into additional segments. Thus, it is possible to
structure the PROFINET network and realize greater network
expansions.
independent of the network structure, the expansion of a
PROFINET segment must not exceed certain connection
lengths:

Copper connection line

(Ethernet twistedpair wire, 22 AWG):
max. 100 m between network stations
(PROFINET endtoend link)

Optical connecting cable

(POF fibreoptic cable, max. 12.5 dB signal attenuation
over the entire connection length):
max. 50 m PROFINET endtoend link

Switches and routers for Industrial Ethernet are available on

the market from various companies. There are many IP20,
IP65 or IP67 components.

Unmanaged switches:
for small Ethernet solutions with a low network load or
minimal requirements for deterministics.

Managed switches:
for comprehensive network solutions, with diagnostics
and control functions

Note
Make sure that any intermediate switches and routers
support the PROFINET function Fast Startup" (FSU) when
you use this additional function. Further information on
FSU can be found in section B.1.3.

2.1

General information
The configuration of the CPX bus nodes for PROFINET
depends on the control system used.
The basic procedure and the required configuration data are
presented in the following pages.

Switching on the power supply

Caution
Danger of malfunctions, damage or injuries to people
Before commissioning, ensure that the connected
elements (e.g. actuators) do not perform any undesired or
uncontrollable movements.
If the safety concept of your machine/system permits,
commission the CPX terminal with both operating voltages
but without compressed air. You can then test the CPX
terminal without triggering undesired reactions.

Note
Please observe the switchingon instructions in the manual
of your control system (PLC/IPC).
Separatesupply

If the control system and the field bus slaves have separate
power supplies, the devices must be switched on in the
following sequence:
1. Switch on the operating voltage supply of all bus
subscribers (I/O devices).
2. Switch on the operating voltage supply for the controller.

2. Commissioning

Addressing, configuration and parametrisation

Addressing

The address space of a CPX terminal in the PROFINET network

is limited. Determine the number of assigned inputs and
outputs before commissioning or configuring the CPX
terminal (see section 2.2 regarding address assignment and
section 2.3 regarding addressing).
Addressing the individual modules requires the higherorder
controller: PROFINET uses moduleoriented addressing,
i.e.each module is addressed separately (in contrast to
blockoriented addressing of other fieldbus systems).
The controller uses the following for addressing:

IP addresses and MACIDs

Fieldbus device names, in short device names.

Configuration

Configuration of a CPX terminal and the related CPX bus node

depends on the control system used. The fundamental
procedure, PROFINETspecific preparations and the main
configuration steps are depicted on the following pages
(seesection 2.6).

Parametrisation

A CPX terminal in the PROFINET network can be parametrised

through the control system (PLC/IPC), a handheld control unit
(CPXMMI) or the Festo Maintenance Tool (CPX FMT)
(seesection 2.8).

2.2

Address assignment
Note
The address space of a CPX terminal in the PROFINET
network is limited.
The CPX bus node for PROFINET provides the CPX terminal
with an address space of up to 64 bytes for inputs (I) and
64 bytes for outputs (O).
Each module of the CPX terminal occupies a certain
number of I/O bits, bytes or words in the context of
module communication.
Please refer to the following tables (Tab. 2/2 to Tab. 2/7)
for the number of I/O bytes occupied (of the respective
module).
Also, certain functions, e.g. the I/O diagnostics interface
(STI), reduce the number of available I/O bytes (in favour
of status or diagnostics functions).
Take account of this fact for the planning of your CPX
terminal.
Before starting up or configuring the CPX terminal, determine
the number of assigned inputs and outputs. Tab. 2/8 assists
you with this.
Use the configuration documents, the handheld control unit
(CPXMMI) or the Festo Maintenance Tool (CPXFMT) to
determine address assignment or terminal configuration.
In the handheld display, the individual modules of the CPX
terminal are displayed with the respective module identifiers.
Using the module identifier and the following tables, you can
determine the module type and, with it, the number of inputs
and outputs occupied by the module.

2. Commissioning

Module identifiers

Each module, including the bus node, has its own identifier,
the socalled module identifier. It serves to determine and
localise the module type, for example as part of
configuration. Apply the module identifiers from left to
right corresponding to the physical order as installed in the
CPX terminal in your configuration program (e.g. Siemens
SIMATIC STEP 7, see section 2.7).
In graphically oriented configuration programs, the module
identifiers are typically found in a separate listing of all
available hardware modules or field devices, e.g. in a module
directory or module catalogue.

Electric modules
Tab. 2/1 shows the assigned address space of the bus node
in the Remote Controller operating mode.
Tab. 2/2 to Tab. 2/4 give an overview of the assigned address
spaces of different electrical modules and of the bus node in
the remote I/O operating mode.
The address assignment within the individual CPX I/O
modules can be found in the manual for the I/O module
(P.BECPXEA ...).
Details on the CP interface can be found in the manual for the
CP interface (P.BECPXCP...).

Configuration
of the bus node

In the remote controller (RC) operating mode, only the

identifier of the bus node will be configured (see Tab. 2/1).
In the remote I/O (RIO) operating mode, the identifiers of
the bus node (including diagnostics mode), the CPX
modules and, if present, the pneumatics modules are
configured (see Tab. 2/2).

Configuration of the
pneumatics (valves)

The valves are configured according to the pneumatic

interface used:

Valves of type 03 (Midi/Maxi), type 12 (CPA) and

type 44/45 (VTSA/VTSA F or ISO):
When extensions are added to the valve side, only one
configuration is required for the pneumatic interface. In
the pneumatic interface, the number of valve coils is set
using a DIL switch.

Valves of type 32 and 33 (MPA, MPAF, MPAP and

MPAFP or VPPM pneumatic modules):
From the technical point of view, the individual MPA
pneumatic modules each represent an electric module for
controlling the attached valves.
A configuration is required for each pneumatic module of
type MPA... or VPPM:
} Pneumatic modules of type MPA1 each occupy 1 byte
O or 8 outputs regardless of how many valves are
attached to the pneumatic module.
} Pneumatic modules of type MPA2 each occupy 1 byte
of O or 8 outputs, but only 4 bits are used.
} Pneumatic modules of type MPAP or MPAFP each
occupy 2 bytes of I or 16 inputs.
} Pneumatic modules of type VPPM each occupy 4
bytes of address space, i.e. 2 bytes of I / 2 bytes of O or
16 inputs and 16 outputs.

Addressing
Basic rules for addressing

The bus node counts as a module with 0 inputs and

0 outputs when the status bits and the I/O diagnostic
interface are deactivated.

Observe the instructions regarding address assignment in

section 2.2.

The address assignment of the inputs does not depend

on the address assignment of the outputs.

Counting moduleoriented, from left to right

(corresponding to the physical sequence)

Addressing bytebybyte: Modules with less than 8 bits

occupy 8 bits or 1 byte of address space, but do not use
all this space.

The I/Os of different module types are assigned

separately from each other. Observe the sequence of
addressing: see Tab. 2/9.

Note
If necessary, status bits or the I/O diagnostic interface can
be activated by DIL switch (see Tab. 1/2):
If the 8 status bits are activated, they will occupy the
first 16 inputs in the address range (8 used).
If the I/O diagnostic interface is activated, it will occupy
the first 16 inputs and 16 outputs in the address range.

Address assignment and addressing after expansion or conversion

A speciality of the CPX terminal is its flexibility. If the demands
placed on the machine/system change, the equipment fitted
on the CPX terminal can also be modified.

Caution
If the CPX terminal is extended or converted at a later
stage, the input/output addresses may be shifted. This
applies in the following cases:
if additional modules are inserted between existing
modules.
if existing modules are removed or replaced by other
modules which have more or fewer input/output
addresses.
Interlinking blocks (CPA) or pneumatic manifold blocks
(midi/maxi) for singlesolenoid valves are replaced by
interlinking blocks/manifold blocks for doublesolenoid
valves or vice versa (see Pneumatics description).
if additional manifold subbases (CPA) or subbases
(Midi/Maxi) are inserted between existing subbases.
The diagnostic mode (status bits or the I/O diagnostic
interface) is activated/deactivated.

Instructions for commissioning with Siemens SIMATIC STEP 7

Commissioning of a CPX terminal requires an exact
procedure, since, possibly for each station, i.e. for each I/O
device in the PROFINET network, different configuration
specifications are required due to the modular structure.
The following sections describe the basic configuration steps
with the SIEMENS PLC SIMATIC S7 and the Siemens SIMATIC
STEP 7 configuration and programming software.
Operation of the STEP 7 software is assumed to be known in
the following.
Other controller systems may require other settings or a
different procedure.

Note
Please observe the configuration instructions in the
manual of your control system (PLC/IPC).

The illustrations and specifications in this description refer to

the following variants:

There are different configuration programs available for a
Siemens PLC. Observe the corresponding procedure for
your configuration program.

Caution
Danger of malfunctions, damage or injuries to people
A valve terminal with defective configuration will also be
put into operation. However, only the modules which have
been correctly configured for type and position will be
activated.
Before commissioning, ensure that the connected
elements (e.g. actuators) do not perform any undesired or
uncontrollable movements.
If necessary, disconnect the load power supply and
compressed air supply.

Parametrisation
You can individually set the behaviour of the CPX terminal
through parametrisation. We distinguish between the
following parametrisation variants:

System parametrisation, e.g. deactivating error messages

etc.

Module parametrisation (modulespecific and

channelspecific), e.g. module monitoring, settings for
errors, adjustment of debouncing times for the inputs,
etc.

Parametrisation of the diagnostics memory

A detailed description of the individual parameters as well as

basic information about application can be found in the CPX
system description (P.BECPXSYS...).
Parameter lists for the various CPX modules can be found in
the corresponding descriptions for the modules
(P.BECPXEA..., P.BECPXAX..., P.BECPXCP... etc.).

Note Module parameter in the operating mode FSU

In the Fast Startup" (FSU) operating mode, the module
parameters cannot be set through the control software
(exception: VTSAD pneumatics interface).
Use the Festo Maintenance Tool (FMT) or the handheld
(MMI) to make the required settings.

2.8.1

Start parametrisation while switching on (system start)

The parametrisation at system start of the CPX terminal
is initially dependent on the setting of the system start
parameter. This parameter specifies whether the start
parametrisation will be loaded from the PROFINET I/O
Controller or from the CPX bus node.

Note
The start parameter set is loaded again (according to the
rules described above) after every interruption of the
network connection or of the power supply.
An exchange of individual CPX modules is therefore possible
without the need for new manual parametrisation.

Sequence of the start parametrisation when

switching on the CPX terminal
Sequence with system start parameter Default
Parameters":

The PROFINET I/O controller loads the start parameter set

into the CPX bus node.

The bus node then distributes the parameter set to the

modules.
It does not matter whether there is a memory card in the
bus node or not.

Sequence with system start parameter Saved

3.5.1

Diagnostics via PROFINET

Basic information

PROFINET forms the basis for comprehensive diagnostics

functions and information over your automation network,
e.g.detailed modulerelated and channelrelated status
information and error recognition in the online mode of the
configuration software and in the PLC user program.
The following sections provide an initial view of the use of the
online diagnostics using the configuration and programming
software (see section 3.5.2) and the userspecific diagnostics
using function modules (see section 3.5.3).

Error characteristics
The behaviour of the CPX terminal for the following errors is
dependent on the configured behaviour of the controller
(ofthe Master), i.e. of the PLC or IPC and the parametrised
failsafe setting:

telegram failure

stop of the controller (of the master)

network interruption.

Depending on the parametrisation, the outputs (valves and

electric outputs) will be switched off (factory setting),
switched on or retain their status.
Further information about the failsafe setting can be found in
the CPX system description P.BECPXSYS...

Festo P.BECPXPN IOEN en 1008b

313

3. Diagnosis

You can set two types of controller error characteristics:

Hard error characteristics: the controller switches to the

operating mode STOP" when an error occurs.

Soft error characteristics: the controller remains in the

operating mode RUN" when an error occurs.

Warning
Ensure that valves and outputs are put into a safe state
if the faults named occur.
An incorrect status of the valves and outputs can lead to
dangerous situations!

Note
Please note the following if the outputs are reset after
PLCstop, network interruption or fault:
Singlesolenoid valves move to the basic position.
Doublesolenoid valves remain in the current position.
Midposition valves move to the mid position (depending
on the valve type: pressurised, exhausted or blocked).

3. Diagnosis

3.5.3

Userspecific diagnostics with Siemens STEP 7

The diagnostics for PROFINET are supported in STEP 7 by
Organisation Modules (OMs) and Function Modules (FMs).
OMs and FMs consist of individual function instructions and
thus form special program modules, socalled Instruction
Lists (AWL) which can be integrated in userspecific
programs.
Organisation Modules start in response to an error or a
devicerelated diagnosis and are used thereby for localisation
of the source of the error while Function Modules read the
diagnostics of the CPX bus node and write to a data area of
the user program (see example in Fig. 3/3).
In this way, the systemspecific diagnostics are individually
integrated in comprehensive, higherorder diagnostics
systems.
The following OMs and FMs can typically be used for
diagnostics purposes: OM 82, OM 86 and SFM 54
(see Tab. 3/10).

B.1

Bus node operating modes

B.1.1 Remote I/O Explanation of the operating mode

All functions of the CPX terminal are controlled directly by the
PROFINETIO controller or a higherlevel PLC.

Control of the CPX terminal (or of the CPX valve terminal;

also designated as IO controller)

Data exchange between controller and modules

Parametrisation of the modules

Diagnostics

Controller and CPX terminal communicate via PROFINET.

In doing so, the bus node takes over the connection to
PROFINET and processing of the data exchange:

Protocol implementation

Forwarding of incoming and outgoing data

PROFINET RT
The PROFINET RealTime Protocol (RT) is used here.
(in both operating modes)
An FEC,possibly integrated in the CPX terminal, works as a
passive module, i.e. without controller. In this case, the FEC
can be used for connection to other networks, for example:
The FEC takes over the forwarding of incoming and outgoing
data and thus behaves like an I/O module.

B.1.2 Remote controller explanation of the operating mode

A CPXFEC of CPXCEC integrated into the CPX terminal takes
over control of the terminal (also described as IO controller)
as the local controller of a larger system, for example.
Requirements for this operating mode:

A CPXFEC or CPXCEC is a component of the CPX terminal.

Make sure that the DIL switches of bus nodes and

CPXFEC or CPXCEC are set corresponding to the
operating mode (see Tab. 1/4 and description of
P.BECPXFEC or P.BECPXCEC).

If necessary, settings must also be adapted to the

software level, such as in the programside hardware
configuration.

The bus node takes over the additional connection to

PROFINET, if applicable; that means, connection to the
higherorder network is not required in this configuration to
operate the CPX terminal. In this case, connection to
PROFINET provides supplementary functions:

B4

The FEC or CEC can communicate at the fieldbus level

over a datafield of 8 or 16 IObytes in size, such as with a
PROFINET IO controller or a higherlevel controller.
A higherlevel PLC can, for example, call up status
information of the valve terminal using this interface and
adjust or optimise the controller correspondingly with
other system parts.

B.1.3 Fast Startup" explanation of the additional function

The remote I/O operating mode can be combined with the
additional function Prioritized Startup.
The additional function Prioritized Startup, also designated
Fast Startup" (FSU), ensures a faster startup of the
CPXsystem.
The following sections summarise the specific information
from the previous chapters to provide a comprehensive
overview of this function.
The summary also simplifies conversion of an existing
CPXsystem to Fast Startup".
Requirements

The additional function Fast Startup" requires certain

hardware, firmware and software versions as well as the
current GSDML file, which must be installed as part of
commissioning.

Hardware, firmware and software requirements can be

found in Tab. 2/2 (in section 2.5.2).

Tab. 2/2 also includes information about the

required GSDML file: For Fast Startup" you need
version 2.2 (orpossibly a higher version),
e.g. GSDMLV2.2FestoCPX20100517.xml.

Festo P.BECPXPN IOEN en 1008b

Observe the wiring information regarding FSU

in section1.6.2.

Installation of the GSDML file is described in section 2.5.5.

Restrictions

Crossover detection is not available in remote I/O operating

mode with additional function Prioritized Startup" (FSU):

Use an appropriate cable (see section 1.6.2).

Make sure that the function Autonegotiation/

Autocrossover" is deactivated in your control software
before placing the system in operation (see section 2.6.4).

If necessary, the function Autonegotiation/

Autocrossover" must also be deactivated on the
hardwareside, in the basic setting of your controller (PLC)
or switches or routers in between: Check this with the
port settings.

The additional function FSU has restrictions in

parametrisation:

Module parameters cannot be set over the controller

software and must therefore be entered using CPXFMT or
CPXMMI.

For the system start, the function System Start with

Saved Parameters" (Saved" or Stored Parameters")
must be activated to ensure that the parameters entered
using FMT or MMI are used.

Additional information on parametrisation can be found in the

corresponding sections, especially section 2.8.

Activation/change

The change of operating mode to Fast Startup" is

performed in the control software, e.g. Siemens STEP 7:
Observe the following note!

Note
Activation of the additional function Fast Startup" (FSU)
Observe that the change to Fast Startup" in the control
software must be made at two configuration levels:
Basic hardware configuration
CPXterminal properties } section 2.6.4,
Set up Prioritized Startup (FSU)"
CPXterminal configuration
Allocate configuration table } section 2.7.1,
Open station symbol" and Select bus node"
with additional function FSU
Additional information on the FSU function can be found in
the Siemens PROFINET system description, section
Prioritized Startup".
