About this Document

2 Function
2.1 General
The product is intended for the operation of a system CPX-E in an Ethernet network using either the
EtherNet/IP or ModbusTCP protocols. Data transfer is on the basis of Industrial Ethernet following the
IEEE 802.3 protocol.
The product has two equivalent Ethernet interfaces (RJ45) with integrated switch, and therefore sup-
ports both star and line topology. The integrated switch enables the division of the network into differ-
ent segments. The network can be divided into additional segments with the use of 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: 192.168.1.1, subnet mask: 255.255.255.0
(DHCP=active)
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 (EDS file). This contains all the information required to parameterise the system CPX-E
via control software (e.g. RSLogix5000).
The current device description file is available on the Festo Support Portal (èwww.festo.com/sp).
2.1.3 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 “Priority start-up” function (QuickConnect), crossover detection (auto MDI/MDI-X)
must be deactivated.
2.1.4 QuickConnect
The “QuickConnect” function ensures rapid start-up of the system CPX-E.
Function
8 Festo — CPX-E-EP — 2020-01a

When using the “QuickConnect” function, crossover detection (auto MDI/MDI-X) must be deactivated,
and the transmission rate and duplex mode of the network connections to the bus module and to the
higher-order controller must be set to be identical.
The IO-Link master module CPX-E-4IOL-… does not support the "QuickConnect" function.

2.1.7 Control Elements
Rotary/DIL switches Function
The 3 rotary switches are used to set the 4th octet of the IP address
(192.168.1.XXX).
Possible Settings:
– 0 = Dynamic addressing via DHCP/BOOTP
– 1…255 = permissible address range
Valid Values:
– EtherNet/IP: 300…555 (IP address = value – 300)
– ModbusTCP: 600…855 (IP address = value – 600)
– Factory setting: 900
In the case of invalid values, the IP parameters are reset to dynamic
addressing (DHCP).
The diagnostic mode is set using the DIL switches è Tab. 6 DIL Switch.
Tab. 5 Rotary/DIL Switches
In the case of invalid values, the IP parameters are reset to dynamic addressing (DHCP). For switch
positions 0…255, the protocols EtherNet/IP and ModbusTCP can be used in parallel. The rights to
control the outputs are assigned to the protocol that sends outputs first.

2.2 Address Assignment
The CPX-E system 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.
Function
11Festo — CPX-E-EP — 2020-01a

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.
– The numbering goes from left to right.
– 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. The
following sequence applies:
– Bus module with status bits or I/O diagnostic interface (if activated via DIL switch)
– Analogue modules
– Technology modules
– Digital modules

2.4.1 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.
Function
14 Festo — CPX-E-EP — 2020-01a

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 2.4.2 I/O Diagnostics Interface.
You can find detailed information about status bits in the “Description of system CPX-E”
è 1.1 Applicable Documents.
2.4.2 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.
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 EtherNet/IP
The system CPX-E supports the following diagnostic options via the EtherNet/IP protocol.
The following diagnostics options are supported here:
– Explicit messaging via EtherNet/IP Master
– Diagnostics via PLC user program. The I/O diagnostic interface can also be read out here.

2.6 Diagnostics via ModbusTCP
The system CPX-E enables diagnostics via the ModbusTCP protocol:
– Status register è 3.2.2 Status Information (Group A)
– I/O diagnostics interface è 3.2.3 Process Data (Group B and D)
– Diagnostic memory è 3.2.4 Diagnostic Memory (Groups C and E)
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.
