2 Function
2.1 General
The product is intended for operating a system CPX-E in a PROFINET IO network. Data is transmitted on the basis of
Industrial Ethernet following the IEEE 802.3 protocol. 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
A device description file (GSDML file) is used for configuring the bus module in the higher-order controller software.
This file contains all the information required for parameterising the system CPX-E using controller software (such as
Siemens STEP 7).
The device description file is available on the Festo Support Portal (èwww.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 “Priority start-up” function (Fast Start-Up), crossover detection (auto MDI/MDI-X) must
be deactivated.
2.1.5 Priority start-up (Fast Start-Up)
The “Priority start-up” function (Fast Start-Up) ensures that the system CPX-E is able to start up quickly.
When using the “Priority start-up” function (Fast Start-Up), crossover detection (auto MDI/MDI-X) must
be deactivated and the bus module must be parameterised as a slave.
2.1.6 Identification & Maintenance (I&M)
The “Identification & Maintenance” (I&M) function acts as an electronic product label for the bus module and
provides standardised, non-proprietary access to device-related information about 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 is independent of the address assignment of the outputs.
– 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).
