Fig. 32: Display values in the Web browser

Just as in the display, you can switch between the display groups in the Web server. The measured

values are updated automatically (direct via "link": off/5s/15s/30s/60s). In addition to the mea-

sured values, status/limit value flags are also displayed.

The data can be read out via the Webserver in HTML or XML format.

When using an Internet browser, it suffices to enter the address http://<IP address> to display the

information as HTML in the browser. In addition, two versions of the XML format are available.

These versions can be integrated into additional systems as required. The two XML versions contain

all the measured values which are assigned to any group.

Note!

The decimal separator is always displayed as a period in the XML file. All times are given in UTC.

The time difference is indicated in minutes in the subsequent entry.

Version 1:

The XML file is available in ISO-8859-1 (Latin-1) encoding at the address http://<IP address>/

index.xml (alternatively: http://<IP address>/xml). However, this encoding cannot display some

special characters such as the sum sign. Strings such as digital status information are not transmitted.

Version 2:

A UTF-8 encoded XML file can be retrieved at the address http://<IP address>/main.xml All the

measured values and the special characters can be found in this file.

The structure of the channel values in the XML file is explained below:

<u1>m

/h</u1>

<man>Endress+Hauser</man>
