General remarks

The product is intended for the operation of a system CPX-E in an Ethernet network using either the EtherNet/IP or
the Modbus TCP protocol. Data is transmitted 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 supports both star
and line topology. The integrated switch enables the division of the network into different segments. With the use of
additional switches and routers, the network can be divided into additional segments. This makes it possible to
structure the network and achieve networks of greater extent.
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 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), so both patch cables and crossover cables can
optionally be used.
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.
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.
