IP address
In delivery condition and after resetting to factory defaults, automatic
configuration of the network address via DHCP (Dynamic Host Configuration
Protocol) is set. The module retrieves the IP address and subnet mask from
the DHCP server. No changes are required for automatic addressing: a
DHCP server can reference the unique MAC address to always assign the
same IP address to the module.
With the rotary coding switch position 999, the module can be addressed at
any time via the static IP address
192.168.1.1
.
IPv4 addresses comprise of 4 dot-separated decimal blocks (e.g.,
192.168.1.1). Each block has a length of 8 bits. This means that each block
covers a value range of 0–255.
The IP address comprises of a network part and a host part. For different
computers to be able to communicate directly, the network part of their IP
address must be identical (subnet mask). In contrast to this, the host address
must not be assigned multiple times on a network. For example, if an IP
address of
192.168.1.1
is set for a module, the administration computer
must have an IP address in the range
192.168.1.2
through
192.168.1.254
. The subnet mask in this case is
255.255.255.0
.
Use the 3 coding dials on the module for manual addressing. After the power
supply is restored, the modules read the switch settings. The selected
operation mode overwrites the stored settings.
An address is set via the rotary encoding switch only overrides the last octet
of an IP address. Configuration of the first three octets is only possible via the
web server.
The factory settings of the static network parameters are:
IP address:
192.168.1.1
Subnet mask:
255.255.255.0
Gateway address:
0.0.0.0
NOTE
The IP address can also be configured on the software side in the integrated
web server (see
).
