Http (Hypertext Transfer Protocol) - WAGO -I/O-SYSTEM 750 Technical Description, Installation And Configuration

IP addresses of the DNS
servers
Host name
When using the bootstrap protocol for configuring the node, the network
parameters (IP address, etc... ) are stored in the EEPROM.
Note
The network configuration is only stored in the EEPROM when the BootP
protocol is used, although not if configuration is done via DHCP.
The BootP protocol is activated in the (programmable) fieldbus coupler or
controller by default.
When the BootP protocol is activated, the (programmable) fieldbus coupler or
controller expects a BootP server to be permanently present.
If, however, there is no BootP server available after a power-on reset, the
network remains inactive.
To operate the (programmable) fieldbus coupler or controller with the IP
configuration stored in the EEPROM, you must first deactivate the BootP
protocol.
This is done via the web-based management system on the appropriate HTML
page saved in the (programmable) fieldbus coupler or controller, which is
accessed via the "Port" link.
If the BootP protocol is deactivated, the (programmable) fieldbus coupler or
controller uses the parameters stored in the EEPROM at the next boot cycle.
If there is an error in the stored parameters, a blink code is output via the IO
LED and configuration via BootP is automatically switched on.

HTTP (HyperText Transfer Protocol)

HTTP is a protocol used by WWW (World Wide Web) servers for the
forwarding of hypermedia, texts, images, audiodata, etc.
Today, HTTP forms the basis of the Internet and is also based on requests and
responses in the same way as the BootP protocol.
The HTTP server implemented in the (programmable) fieldbus coupler or
controller is used for viewing the HTML pages saved in the coupler/controller.
The HTML pages provide information about the coupler/controller (state,
configuration), the network and the process image.
On some HTML pages, (programmable) fieldbus coupler or controller settings
can also be defined and altered via the web-based management system (e.g.
whether IP configuration of the coupler/controller is to be performed via the
DHCP protocol, the BootP protocol or from the data stored in the EEPROM).
The HTTP server uses port number 80.
