7.1 Alternative IP address assigning
7.1.1 Using DHCP-/BOOTP protocol
Many networks use DHCP (Dynamic Host Configuration Protocol)
or BOOTP for centralized and dynamic assignment of the IP
addresses. Which of the two protocols is used in any individual
situation makes no difference with respect to Web-IO devices,
since DHCP is simply a downward compatible expansion of
BOOTP. DHCP servers thus use the same requests as BOOTP
clients.
The following parameters can be assigned to the Web-IO Ana-
log using these protocols:
■
IP address
■
Subnet mask
■
Gateway address
Function
To obtain an IP address the device sends a corresponding
BOOTP request as a broadcast to the network after each restart.
The resulting reply generated by the DHCP/BOOTP server
contains along with the IP address the subnet mask and
gateway address. The Web-IO immediately copies this
information to its non-volatile memory.
