The NOE771xx’s HyperText Transport Protocol (HTTP) Server allows you to view
the following information:
z Module’s Ethernet statistics
z Controller and I/O information
z BOOTP/DHCP/FDR (Faulty Device Replacement) Server information
z Global Data (Publish / Subscribe)
The HTTP Server’s HTML pages allow you to configure the module’s
BOOTP/DHCP/FDR Server and SNMP Agent.
The HTTP Server is protected with a default name and password. The default name
and password are both USER, and both are case sensitive. They can both be
changed via the Configuration page on the NOE 771 0x’s Web Embedded Pages
(see the Installing the Module chapter in the Quantum NOE 771 xx Ethernet
Modules User Guide ).
For the NOE7711x modules, they can be changed via the FactoryCast Configurator.
The NOE771xx supports a maximum of 32 HTTP simultaneous connections.
NOTE: Browsers may open multiple connections so 32 HTTP connections does not
indicate 32 simultaneous users.
NOTE: The NOE7710x module does not support user downloaded Web pages. You
will need to purchase the 140NOE7711x module to support that requirement.
Address Servers
The following information describes the services provided by the Address Servers:
z BOOTP Server
z DHCP Server
BOOTP Server
NOTE: The BOOTP Server is available on the 140NOE771 -00 and -10 models.
The BOOTstrap Protocol (BOOTP) software, compliant with RFC 951, is used to
assign IP addresses to nodes on an Ethernet network. Devices (hosts) on the
network issue BOOTP requests during their initialization sequence, and a BOOTP
Server that receives the request will extract the required IP address information from
its database and place it in BOOTP response messages to the requesting devices.
The devices will use the assigned IP addresses, received from the BOOTP Server,
for all communication occurring on the network.
