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 an EtherCAT network. Data transfer is
on the basis of Industrial Ethernet following the IEEE 802.3 protocol. The product has two Ethernet
interfaces (RJ45) and supports any topologies. The EtherCAT address (0…4095) can be set manually
using DIL switches, which means that the “HotConnect” function (for coupling and decoupling
devices during operation) can be used.
2.1.1 Web Server
The integrated web server provides read access to the key parameters and diagnostic functions of the
automation system CPX-E.
The web server can be reached via the "Ethernet over EtherCAT (EoE)" protocol and must be con-
figured accordingly in the controller. The IP address and the subnet mask must be assigned individu-
ally.
To access the web server, the following settings must be made:
– IP address on PC (e.g. 192.168.2.100)
– IP address on the higher-order controller for the connection to the PC (e.g. 192.168.2.10)
– P address and subnet mask on the higher-order controller for the connection to the bus module
(e.g. 172.16.1.1; 255.255.0.0).
– Activation of “Ethernet over EtherCAT (EoE)” and “IP Routing” on the higher-order controller
– An IP address and subnet mask must be assigned to the bus module (e.g. 172.16.1.100;
255.255.0.0)
The subnet mask of the bus module must correspond with the subnet mask for the connection to the
bus module on the higher-order controller.
– In the Windows program "cmd.exe", the following routing setting must be entered: "route add
172.16.0.0 mask 255.255.0.0 192.168.2.10"
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 (ESI file). This contains all the information required to parameterise system CPX-E via
controller software (e.g. Beckhoff TwinCAT).
The current device description file is available on the Festo Support Portal èwww.festo.com/sp.
Function
7Festo — CPX-E-EC — 2020-01a

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.
2.1.4 Distributed Clocks
The product supports the "Distributed Clocks" function for precise synchronisation of stations in an
EtherCAT network. Applications that require simultaneously coordinated actions can therefore be
implemented.
The following CPX-E modules permit synchronous operation when using “distributed clocks”:
• Digital input module CPX-E-16DI(-P)
• Digital output module CPX-E-8DO(-P)
• Counter module CPX-E-1CI

Rotary/DIL switches Function
The 3 rotary switches are used to set the hexadecimal coding for the Ether-
CAT "Explicit Device ID" of the bus module.
Possible settings:
– 0 = stored EtherCAT address, no "Explicit Device ID" assigned
– 1…4095 (1h…fffh) = permissible address range
If set to 0, the address of the bus module is automatically assigned by the
EtherCAT master (auto-increment).

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. 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 16inputs (only 8inputs are used).
– 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 I/O addresses are assigned in ascending order according to the module number.

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.
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.
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.
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 EtherCAT
The availability of diagnostic information via the EtherCAT network depends on the settings of the DIL
switch and parameterisation. To guarantee that error messages of system CPX-E are automatically dis-
played in the controller software, the I/O diagnostic interface must be activated.

this way.

The diagnostic message are written to a buffer (80 bytes). 2 operating modes are available for pro-
cessing diagnostic messages:
– Overwrite mode:
When the number of diagnostic messages reaches 64, old diagnostic messages are overwritten.
– Acknowledge mode:
A diagnostic message must first be acknowledged before it can be overwritten with a new dia-
gnostic message. When the number of unacknowledged diagnostic messages reaches 64, new
diagnostic messages will not be saved and will be lost.
Specifying the Operating Mode for Diagnostic Message

Mapping of “New Message Available” Message
For simplification of the diagnostic evaluation, the module offers the option of signalling the existence
of a new diagnostic message through the process data. To do this, the object “New message
available” can optionally be mapped to the process data.
Deactivating/Activating Emergency Message
The emergency message (è 2.5.3 Emergency Message) can be deactivated and activated by the dia-
gnostic object 0x10F3 (sub-index5, bit0).
