8.1.1.2 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 gateway.
The device comes delivered with a default IP address that can be restored at any time by pressing the IP-Addr.
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 8-1:
Figure 8-1
Default IP Address and IP-Addr. Push-button
To set the default IP address assigned as factory setting, there is the IP-Addr. push-button on the bottom right
of the case on the side of the DIN rail (see Figure 8-1). When pressed (> 3 s), this button activates the factory-
set default IP address. After pressing the IP-Addr. button, the device restarts and the IP address and subnet
mask are temporarily activated in the default IP network configuration. 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 6.3.3.6). After a renewed restart the parameterized network configuration is used again.
Check for Twice Assigned IP Address
An IP address assigned twice, leads to serious malfunction in the 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.
Otherwise, the LEDs (see chapter 10.3) signal that the IP address is already assigned and the device is not
connected to the network. In this case, you have to specify a different IP address.
NOTE
If the device is directly connected to a PC (without Ethernet switch), the PC needs a longer period to be able
to detect the connection and therefore to receive the ARP telegram. In this case it may not be detected when
PC and device have the same IP address.
