Addressing on the Ethernet (basics)
Due to the separation into logical and physical protocol layers
(Ethernet and TCP/IP), there are two types of addresses in a
network:
a fixed Ethernet address (MAC−ID) for each device and
an IP address which is assigned to every device in the
network.
Before the application, data is always sent to or received from
an IP address. In order for the data to reach the receiver, a
correlation must be created between the logical IP address
and the physical Ethernet address. The Address Resolution
Protocol ARP is used for this purpose: An ARP table is saved
in each network PC. This table lists the respective physical
Ethernet address for each IP address in the network. If an
Ethernet address is not listed in the ARP table, the IP driver
can determine what it is with the aid of an ARP request.
Ethernet address
(MAC−ID)
The unchangeable Ethernet address (MAC−ID) of the Compact
Vision System, which is unique worldwide, can be found on
the type plate. With this, you can clearly distinguish between
the different Compact Vision Systems.
IP address
An IP address, according to the standard IPv4, is usually
specified with 4 decimal numbers separated by points
(1 byte each).
Example of an IP address: 192.168.2.10
With an IP address, a network, as well as an individual station
in the network, can be addressed. In addition, the IP address
contains:
the net ID (specifies the address of a network) and
the host ID (specifies the address of an individual station
in this network).
