NOTICE!
Modules with Ethernet interfaces should only be operated in networks if all connected network com-
ponents are supplied by PELV circuits or integrated circuits with equivalent protection.
2 Function
2.1 General
The product is intended for the operation of a system CPX-E in a PROFINETIO network. Data transfer is
on the basis of Industrial Ethernet following the IEEE802.3. Communication takes place in real time,
using the Real-Time Protocol (RT) or the Isochronous Real-Time Protocol (IRT). The product has two
equivalent Ethernet interfaces (RJ45) with integrated switch, and therefore supports both star and line
topology. The network can be divided into segments using additional switches and routers. This
makes it possible to structure the network and extend it further.
2.1.1 Web Server
The integrated web server provides read access to the key parameters and diagnostic functions of the
system CPX-E.
The web server can be accessed by entering the IP address in the address bar of a web browser.
Factory settings of the bus module:
IP address: 192.168.10.3, subnet mask:255.255.255.0
2.1.2 Device Description File
The bus module is configured in the control software for the higher-order controller using a device
description file (GSDML file). This contains all the information required to parameterise the
system CPX-E via control software (e.g. SIEMENS STEP 7).
The current device description file is available on the Festo Support Portal èwww.festo.com/sp.
2.1.3 PROFIenergy
The product supports the PROFIenergy profile for energy management. This makes it possible to
switch off specific consumers that are not required in order to reduce energy demand.
2.1.4 Crossover Detection (Auto MDI/MDI-X)
The product supports crossover detection (auto MDI/MDI-X), which means that there is the option of
using patch cables or crossover cables.
When using patch cables and crossover cables in the same network, crossover detection must be
activated in the higher-order controller. When using the “Fast Start-Up” function, crossover detection
(auto MDI/MDI-X) must be deactivated.
Function
7Festo — CPX-E-PN — 2020-01a

2.1.5 Priority Start-Up (Fast Start-Up)
The “Priority start-up” function ensures that the system CPX-E is able to start up quickly.
When using the “Priority start-up” function, crossover detection (auto MDI/MDI-X) must be deactiv-
ated and the bus module must be parameterised as a slave.
2.1.6 Identification & Maintenance (I&M)
The “Identification and Maintenance” (I&M) function serves as an electronic rating plate of the bus
module and offers uniform, manufacturer-independent access to device-specific online information
over the network.

2.2 Address Assignment
The system CPX-E is composed of a different number of inputs and outputs, depending on the number
and type of modules CPX-E used and the parameterisation of the bus module. The inputs and outputs
are assigned automatically within the system CPX-E. The address assignment (number of allocated
inputs and outputs) on the system CPX-E must be determined prior to commissioning.
• A maximum of 10I/O modules + bus module is permitted in one system CPX-E.
• The address space of a system CPX-E is limited. The bus module provides the system CPX-E with a
maximum address space of 64bytes for inputs and 64bytes for outputs.
• Activated diagnostic functions as well as status bits or the I/O diagnostic interface reduce the size
of the available address space.
2.3 Addressing
2.3.1 Basic Rules for Addressing
– The address assignment of the inputs does not depend on the address assignment of the outputs.
Function
9Festo — CPX-E-PN — 2020-01a

– The bus module counts as a module with 0inputs and 0outputs when the status bits and the I/O
diagnostic interface are deactivated.
– Activated status bits occupy 8inputs.
– An activated I/O diagnostic interface occupies 16inputs and 16outputs.
– The inputs and outputs of different module types are assigned separately from each other.
Addressing is generally carried out by the higher-order controller (in cases where a SIEMENS higher-
order controller is being used).

2.4.2 Status Bits
The system CPX-E provides 8status bits for displaying global common diagnostic messages. The
status bits are configured like inputs and supply coded diagnostic information in the form of logic 0 or
logic 1. If all status bits supply a logic 0, there is no error. If, on the other hand, a status bit supplies a
logic 1, there is an error. In order to make use of the status bits function, the bus module of the
system CPX-E must be configured accordingly.
The status bits are shown in the process image if this has been specified by selecting the catalogue
entry “E-PN [Status]” in the hardware configurator.
If different errors occur simultaneously on different module types, errors cannot be assigned. To
clearly determine errors, the I/O diagnostic interface can be used è 2.4.3 I/O Diagnostics Interface.
You can find detailed information about status bits in the “Description of system CPX-E”
è 1.1 Applicable Documents.
Function
13Festo — CPX-E-PN — 2020-01a

2.4.3 I/O Diagnostics Interface
The system CPX-E provides an I/O diagnostic interface in the form of 16input bits and 16output bits
for reading detailed diagnostic information. The I/O diagnostic interface can be used, for example, to
precisely determine the module and channel on which an error has occurred. In order to make use of
the I/O diagnostic interface, the bus module of the system CPX-E must be configured accordingly.
The I/O diagnostic interface is shown in the process image if this has been specified by selecting the
catalogue entry „E-PN [STI]“ in the hardware configurator.
You can find detailed information about the I/O diagnostic interface in the “Description of system CPX-
E” è 1.1 Applicable Documents.
2.5 Diagnostics via PROFINET IO
The system CPX-E supports diagnostics options via PROFINETIO in accordance with IEC61158; for
example, module-related and channel-related status information as well as error detection in the
online mode of the control software and in the PLC user program.
2.5.1 Error Numbers
With the exception of the CPX-E error numbers listed in è Tab. 12, the CPX-E error numbers in the
PROFINET IO network are transferred with an offset of 1000:

3 Parameterisation
The behaviour of the automation system CPX-E can be parameterised with the aid of suitable software
from Festo or using a higher-order controller. Here, a distinction is made between the following vari-
ants:
– System parameters
– Module parameters (module-specific and channel-specific)
– Parameterisation of the diagnostic memory
You can find a detailed description of the individual parameters in the "Description of the automation
system CPX-E" and in the descriptions of the corresponding modules è 1.1 Applicable Documents.

System parameters Description/setting options
Diagnostic message filter, undervoltage UOUT
Inactive Undervoltage is reported via the network.
Active Undervoltage messages are filtered and not

bus module.
Filter for channel alarms, undervoltage UOUT
Inactive Undervoltage is reported via the network.
Parameterisation
15Festo — CPX-E-PN — 2020-01a

System parameters Description/setting options
Active Undervoltage messages are filtered; a maximum
of one message per module is sent via the net-
work. The undervoltage is also indicated by the
“SF” LED flashing on the bus module.
Filter for combining channel alarms (channel bundling)
Inactive Channel alarms are reported individually via the
network.
Active Channel alarms (e.g.short circuit or under-
voltage) are combined and sent as a common
message via the network. The error is also indic-
ated by the relevant LED flashing on the bus
module.
Analogue process value display (Intel/Motorola format)
Defines how the process values of the analogue
modules are displayed.
Setting options:
– Byte order Intel (LSB-MSB, “Little Endian”):1)
Process values are displayed in Intel format
(least significant bit on the left, most signific-
ant bit on the right)
– Motorola byte order (MSB-LSB, big Endian):
Process values are displayed in Motorola
format (most significant bit on the left, least
significant bit on the right)
This parameter can also be set via the I/O dia-
gnostic interface, using function number 4402 in
bit7:
– Value "0": Intel (LSB-MSB)1)
– Value "1": Motorola (MSB-LSB)
The settings for the byte order and process value
display depend on the higher-order controller
and the associated user programs.
