Basic configuration
All EtherNet/IP devices need an IP address for operation.
In order to be able to set this when it is not known, there is
the BOOTP-DHCP mechanism, which can be controlled
for example in RSLogix using the BOOTP-DHCP server.
This needs a sub-network mask to be entered first (see
section (Sub)net mask ). When a device is switched on, it
sends cyclical telegrams to the BOOTP-DHCP server. The
server indicates this and a new address can be assigned
to the device by clicking on the message. More information
is available in the RSLogix documentation.
If the address is known, it can also be changed using the
integrated web server (see chapter 7 Web server on
page 26).
(Sub)net mask
An IP address has 4 bytes (32 bits) and can therefore
address more than four billion subscribers. Ethernet
networks are therefore segmented. The address space is
divided into a network part and device part.
The network part must be the same for all devices on the
network, while the device part must be different for each
device on the network. The net mask determines which
bits are assigned to the network part and must be reached
via routers on other networks. The net masks should thus
be the same for all devices in an IP network, i.e. be in the
same sub-network.
Communication without an interim router is only possible
between subscribers with a network address with the
same network part.
Example:
Net mask: 255 255 255 0 = 1111 1111 1111 1111 1111 1111 0000 0000
IP address: 192 . 168 . 1 . 28 = 1100 0000 1010 1000 0000 0001 0001 1100
Network
part: = 1100 0000 1010 1000 0000 0001
Device part: 28 = 0001 1100
All bits set to 1 in the net mask are assigned to the
network part. With a net mask with 24 set bits, 8 bits are
remaining, and thus 256 addresses for devices. Because
the smallest address (all bits in the device part are 0) and
the largest address (all bits in the device part are 1) are
reserved for the broadcast, 254 addresses are available for
devices in this network.
In the above example the device has the IP address
192.168.1.28. It can communicate with an IP address
between 192.168.1.1 and 192.168.1.254. The factory
default setting for BTL is IP address 192.168.1.1.
