9.1.1.2
IP Address
To enable the device to communicate within the Ethernet network, you have to establish a network configura-
tion consisting of IP address, subnet mask and standard gateway.
The device comes delivered with a default IP address that can be restored at any time by pressing the IP-Addr.
push-button. Each device also has a unique MAC address.
The default IP address and the default subnet mask are imprinted on the side panel, see Figure 9-1:

DIN Rail Side with IP-Addr. Push-button
Default IP Address and IP-Addr. Push-button
The IP-Addr. push-button is located in the lower right corner of the DIN rail side (see Figure 9-1). When pressed
(> 3 s), this button activates the factory-set default IP address. After pressing the IP-Addr. push-button, the de-
vice restarts and the IP address and subnet mask are temporarily activated in the default IP network configu-
ration. The customer-specific IP configuration is not overwritten.
The network configuration settings can be displayed and edited on an HTML page during the parameterization
(see chapter 7.3.4.2). After a renewed restart the parameterized network configuration is used again.
Check for Twice Assigned IP Address
Serious problems can occur if the same IP address is assigned more than once in a communication network.
For this reason, an ARP request is sent to the own IP address during start-up of the device. If no response is
received from the communication network within 2 s, it is assumed that the IP address is not yet used in the
network.
