82 FP Web-Server V.2.8
12.1.3 Generalities on PLC data fields in HTML pages
"Example - Web pages and e-mail" (provided in your installation directory)
is used for the following explanation:
Here you see the HTML page 'MAIN.HTM' of the FP Web-Server. By
clicking the links you can test the individual pages. For example, by clicking
[Display] the DT200 page (with PLC data) is displayed:
Click [On] or [Off] to set the output of the PLC.
This page contains PLC data fields whose data address has been entered in
the HTML source text. The address is replaced by PLC data when the pages
are called up with the browser. For the format (see p. 87) and the input in
HTML code, see also HTTP address, CGI function PLC and calling parameter
(see p. 83).
HTML pages that should also display PLC data need to be marked with the
data name extension .MTM instead of .HTM. This is done with the
assistance of a "HTML-Compiler" (integrated into the Configurator) before
the transmission to the FP Web-Server is carried out by the Configurator.
In the example above, the PLC data are marked in red (optional). These
data were requested from the PLC by the MEWTOCOL address that is
defined in the Configurator project. This '"default" MEWTOCOL address can
be modified by the calling parameter &A=x in the "Location" field. A
description of the parameter can be found under HTTP address, CGI
function PLC and calling parameter (see p. 83).
