Description
DHCP
Activates the Ethernet interface. The IP address, subnet mask, and
gateway IP address are assigned automatically via DHCP
(Dynamic Host Configuration Protocol).
xxx.xxx.xxx.xxx
Activates the Ethernet interface. The IP address is set manually to
the specified value. Example: 192.168.1.128
Note: For the connection to an IP network, it is also necessary to
specify a subnet mask.
When specifying the IP address manually, note that it is an IPv4
address. It consists of 4 numbers between 0 and 255. Certain
address ranges are reserved.
The first number must be less than 224, since addresses starting
from this value are reserved for Multicast messages
Depending on the Subnet mask, the highest device address is
reserved for broadcast messages. For the Subnet mask
255.255.255.0 and the network address 192.168.1.xxx, the
reserved address would be: 192.168.1.255
Depending on the Subnet mask, the lowest device address is
reserved for messages that are addressed to the entire network.
For the Subnet mask 255.255.255.0 and the network address
192.168.1.xxx, the reserved address would be: 192.168.1.0
7.3.2
Subnet Mask
This setting is used to set the Subnet mask. It must be specified if
the IP address was set manually.
ETH_MASK=255.255.255.0
The Subnet mask indicates which part of the IP address represents
the network, and which part represents the device. This subdivision
is achieved by filling in the (binary) Subnet mask from left to right
