Assigning IP Addresses via DHCP

If you want to use DHCP to assign the IP addresses, it happens automatically via
a DHCP server on the network.
The DHCP requests of port 1 and port 2 are dispatched sequentially and not
parallel. Two requests are sent for each port with an appropriate dead time,
afterwards it is changed on the other port.
Port 1 and port 2 may not be operated in the same network.
Total network failure when there are two DHCP servers in the network!
To prevent network failure, never connect a PC, on which a DHCP server is
installed, to a global network. In larger networks, there is usually a DHCP server
already that can cause collisions and subsequent network failure.
There must be a DHCP server in the network for further configuration!
Install a DHCP server on your client PC in the local network if not already
available. You can download a DHCP server free of charge on the Internet.
Assign the DHCP server a fixed IP address and note common subnet!
Note that the DHCP server must have a fixed IP address and that the fieldbus
node and DHCP server must be in the same subnet.
Via DHCP assigned IP addresses are only temporarily valid!
Note that an IP address assigned via DHCP is limited in time. If the DHCP server
is not available at the end of its useful life, the fieldbus node sets the IP address
free and then the fieldbus node is no longer accessible!
The following step is included:
•

Enable DHCP

• Assigning the IP address permanently by option "use IP from EEPROM"
