11.1.2.3

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.

DNS (Domain Name Systems)

The DNS client enables conversion of logical Internet names such as

www.wago.com into the appropriate decimal IP address represented with

separator stops, via a DNS server. Reverse conversion is also possible.

The addresses of the DNS server are configured via DHCP, BootP or web-based

management. Up to 2 DNS servers can be specified. The host identification can

be achieved with two functions; an internal host table is not supported.

11.1.2.5

FTP-Server (File Transfer Protocol)

The file transfer protocol (FTP) enables files to be exchanged between different

network stations regardless of operating system.

In the case of the ETHERNET coupler/controller, FTP is used to store and read

the HTML pages created by the user, the IEC61131 program and the IEC61131

source code in the (programmable) fieldbus coupler or controller.

Cycles for flash limited to 1 million!

Up to 1 million write cycles per sector are allowed when writing the flash for the

file system. The file system supports "Wear-Leveling", so that the same sectors

are not always written to.
