32 Configure a Network Address For a Web Server Module
If you use the module to initiate MSG instructions that use host names
or to initiate emails, you must also define these parameters.
Check with your network administrator to determine if you need to
specify all of the above parameters.
How you configure these network parameters depends on whether
the Ethernet network has a DHCP server.
Assign Network
Parameters When the
Network Has a DHCP
Server By default, the web server module is DHCP enabled. DHCP (Dynamic
Host Configuration Protocol) software automatically assigns IP
addresses to client stations logging onto a TCP/IP network.
If you connect the web server module to a network that has a DHCP
server, that server will assign an IP address to the web server module
and the four-digit display on the front of the web server module will
display each of the four numbers of the IP address.
In the Address field of your web browser, enter the IP address that
displays on the front of the module.
Ethernet Parameter Description
Host Name A host name is part of a text address that identifies the host for a module. The full text
address of a module is host_name.domain_name.
Domain Name A domain name is part of a text address that identifies the domain in which the module
resides. The full text address of a module is host_name.domain_name. The domain name
has a 48-character limit.
If you specify a DNS server, you must enter a domain name. Also, if you send email from
the module, some mail relay servers require a domain name be provided during the initial
handshake of the SMTP session.
Primary DNS Server Address This identifies the DNS server(s), if used in the network. You must have a DNS server
configured if you specified a domain name or a host name in the module’s configuration.
The DNS server converts the domain name or host name to an IP address that can be used
by the network.
Secondary DNS Server Address
