5 Product overview
5.1 Function
The product establishes, as a participant in an EtherNet/IP or Modbus TCP
network, the connection between a higher-order controller and the modules
ofasystem CPX-E.
Web server
The integrated web server provides read access to the key parameters and dia
gnostic 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)

5.4 Control components
Electrostatically sensitive devices.
Before setting the address using the rotary switch, electrostatically
discharge your own body.
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/I P: 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 Fig. 7.
Fig. 6
For switch settings 0 ... 255, the EtherNet/IP and Modbus TCP protocols
can be used in parallel. The rights to control the outputs are assigned to
the protocol that sends outputs first.

9 Commissioning
Note
Malfunction due to the higher-order controller and system CPX-E being switched
on in the incorrect order.
Switch on the higher-order controller and CPX-E system according to the
preset order of the network used.
1. Set up automation project for the higher-order controller with the help of the
corresponding software.
2. Load the device description file into the software è www.festo.com/sp.
3. Configure the system CPX-E in the software:
– System structure
– Network addressing
– I/O addressing
4. Transfer automation project to the higher-order controller.
Further information about commissioning the system CPX-E can be found
in the “Instructions for use of system CPX-E”. Information about the
parameters can be found in the “Description of system CPX-E” and in the
descriptions of the modules used è 1.1 Further applicable documents.
