1.1 Use the future of automation technology today
With the CPX−FEC, the CPX terminal offers today the technol
ogy of tomorrow for automation tasks. Here is an overview of
the possibilities which are offered:
The CPX−FEC can control a CPX terminal independently
(Stand Alone). Use the Festo Software Tool FST 4.1 with
the Hardware Configurator for commissioning, program
ming and diagnosis.

Control the CPX terminal straight away via Ethernet, the
CPX−FEC makes this possible: In the operating mode
Remote I/O Ethernet" the CPX terminal is a field bus
slave on the Ethernet.
A Webserver is incorporated in the CPX−FEC.
With a standard
Web Browser you can access current data. You can transfer
Web pages which you have created into the CPX−FEC in order
to perform more complex tasks from a self−created user inter
face level.
You can set up the CPX−FEC so that it sends e−mails when
previously defined events occur. This
can be e.g. a message
about a diagnostic case or the processing of a certain task.

1.2 The operating modes of the CPX−FEC
The CPX−FEC can be operated in various operating modes
depending on the demand:
Stand Alone
Remote Controller
Remote I/O
The operating mode can be set with DIL switch 1
(see section 2.2.2).
You can connect a handheld of type CPX−MMI to the CPX−FEC
in any operating mode. The handheld serves for fast prelimi
nary commissioning,
parametrizing and diagnosis.

1 CPX terminal controlled by the
CPX−FEC, communication via Ethernet
In this operating mode the CPX terminal is controlled by the
CPX−FEC (as in Stand Alone), but there is also a communica
tion connection with a higher−order controller. Communica
tion can take place via Ethernet or via a field bus:
Remote Controller Ethernet
The CPX terminal is controlled by the CPX−FEC. The FEC also
communicates via Ethernet (Modbus TCP, EasyIP) with a
higher−order controller. You can use IT technology for the
controller, diagnosis and communication (e.g. Webserver,
e−mail, ...). An advantage of this operating mode is that you
only need to use one bus system.
Configure the CPX terminal with FST via the Ethernet inter
face.

2.1 General notes on installation
Warning
Before carrying out installation and/or maintenance work,
switch off the following:
the compressed air supply
the operating voltage supply for the electronics/sensors
the load voltage supply for the outputs/valves.
You will thereby avoid:
uncontrolled movements of loose tubing
uncontrolled movements of the connected actuators
undefined switching states of the electronics.

Caution
The CPX−FEC contains electrostatically sensitive compo
nents.
· Do not touch the electrical contacts of the components.
· Observe the regulations for handling electrostatically
sensitive components.
In this way you will avoid damage to the electronics.

Dismantling and fitting
The FEC is fitted in a manifold sub−base of the CPX terminal
(see Fig.2/2).
Dismantling Dismantle the FEC as follows:
1. Loosen the four screws of the FEC with a Torx screwdriver
size T10.
2. Pull the FEC carefully and without tilting away from the
contact rails of the manifold sub−base.

1. Place the FEC in the manifold sub−base. Make sure that
the grooves with the terminals for electrical contact on
the bottom of the field bus node lie directly above the
contact rails. Press the FEC carefully and without tilting as
far as possible into the manifold sub−base.
2. Insert the
screws so that the self−boring threads can be
used. Tighten the screws at first only by hand.
Tighten the screws with a Torx screwdriver size T10 with

Please note
Check that the setting of the DIL switch is correct before
commissioning the CPX−FEC.
A change in the operating mode is not recognized until
after Power OFF/ON.
The DIL switches must be accessible in order that the
CPX−FEC can be set:
· Remove an IP65/IP67 plug, if fitted, from the program

Contents of this chapter This chapter is the basis for operating the CPX−FEC in the
operating modes:
Stand Alone
Remote Controller (see chapter 5)
Here you will find a description of general commissioning,
parametrizing, programming and diagnosis of the CPX−FEC.
If you operate the CPX−FEC without communication connec
tion to other slaves, this corresponds to
the operating mode
Stand Alone. In this operating mode the FEC controls the
CPXterminal independently.

3.1 Configuration
Use Festo Software Tools (FST 4.1 or higher) with the Hard
ware Configurator in order to configure your CPX terminal
with CPX−FEC. In the following sections you will find the most
important commissioning steps with FST 4.1.
Caution
If you have connected a CPX terminal to your PC for con
figuration: Test projects and programs at first without ac
tive actuators or without compressed air.
You will then avoid damage in the test phase.
A tutorial on configuration with FST can be found in sec
tion1.5. Detailed information on operating the FST can be
found in the FST manual (type P.BE−FST−..).
Follow the instructions in order to carry out a first project
with the CPX−FEC.
3.1.1 Create connection to CPX−FEC
You will require a connection between your PC and the
CPX−FEC if you wish to load projects into the FEC or use the
online functions.
You can use all online functions via the programming
interface or the Ethernet interface. Access to the
Web−Browser is only possible via the Ethernet interface.

3.2 Addressing
Basic rules for addressing
Modules occupy the address range in ascending order
from left to right according to their physical arrangement
in the CPX terminal (module−orientated).
Addressing is carried out word−orientated (16−bit I/O).
Different module types are assigned with different
addresses depending on the address range.
If a module occupies less than 1 word (16−bit I/O), the
remaining
If a module occupies more than 1 word I/O, the following
word in the address area will be used.
The address assignment can be modified module−orien
tated (see below).
bits of the word will not be used.
3.2.1 Default addressing
In default addressing the address assignments of the various
module types are specified in ranges. The following table
shows the assignment:
Module type
Digital inputs and outputs 0 ... 31 0 ... 31
Valves / pneumatic modules 32 ... 63
Analogue inputs and outputs 64 ... 127 64 ... 127
FEC, bus node, technology module 128 ... 255 128 ... 255

3.3 Parametrizing
The CPX terminal is supplied with preset parameters. If re
quired, you can set the reaction of the CPX terminal as well as
the reaction of individual modules and channels by parame
trizing.
A distinction is made between the following parametrizings:
System parameters, e.g.: switching off fault messages,
setting reaction times, etc.
Module parameters
(module and channel−specific), e.g.:
Monitoring, settings in the event of faults, settings for
Forcing
Diagnostic memory parameters
A detailed description of the individual parameters and data
as well as basic information on parametrizing can be found in
the CPX system manual (P.BE−CPX−SYS−..).
The module parameters which are available for the various
modules can be
found in the manual for the relevant module
(e.g. manual for CPX pneumatic interface and CPX I/O mod
ules (P.BE−CPX−EA−..).

You can parametrize the CPX terminal comfortably with the
Hardware Configurator.
Parametrizing can be undertaken for:
the nominal configuration (offline): Parameters are trans
ferred when the project is loaded.

3.3.4 Forcing
By forcing you can manipulate input and output signals.
Actual input signals or status changes by program are
ignored and replaced by the force values.
Warning
Depending on the functioning of the machine/system, the
manipulation of signal states may cause serious injury to
human beings or damage to property.
Be very careful when forcing in order to avoid damage.
Forcing inputs Forcing an input does not modify the input signal itself and
cannot be observed at
status of the input is modified internally and in some cases
has an effect on the program. The forced input status is
transferred to the processing image of the inputs. Therefore

Please note
The online display of the FST always shows the valid signal
status in the processing image. Therefore, observe the
following when forcing:
Forced input states are transferred to the processing
image and therefore recognized by the controller. They
are visible in the online display.
Forced output states are not transferred

troller. They are not therefore represented in the online
display.
