DHCP IP Support

DHCP (Dynamic Host Configuration Protocol) software automatically assigns
IP addresses to client stations logging onto a TCP/IP network.

When DHCP is enabled (factory default Enabled), the unit will request its
network configuration from a DHCP/BOOTP server. Any configuration
received from a DHCP server will be stored in non-volatile memory.

ArmorStart EtherNet/IP will remember the last successful address if DHCP is
enabled. The unit will try to obtain the same IP address from the DHCP server.
If the server is not present (e.g., server fails to power up), the unit will use the IP
address it previously received from the server. The DHCP timeout = 30 s.

Be cautious about using DHCP software to configure your adapter. A DHCP
server typically assigns a finite lease time to the offered IP address. When fifty
percent of the leased time has expired, the ArmorStart Ethernet adapter attempts
to renew its IP address with the DHCP server. The possibility exists that the
adapter will be assigned a different IP address, which would cause the adapter to
cease communicating with the controller.
