CUSTOM PAGES
Pages in XML format and the links with direct access to FieldLogger pages are available only from
firmware version 1.10 on.
FieldLogger can serve web pages that are hosted in its SD card, since they are located in the “webserv” folder. These
pages can use many information directly from FieldLogger, like channels values and units, clock time and serial
number.
Working conditions
•
All needed files must be placed inside the “webserv” folder in the SD card.
•
FieldLogger works in the “8.3” file name format, so no file should have more than 8 characters (plus the 3 of
the extension).
•
Files with markers that should be replaced by FieldLogger information need their names to start with the “_”
character. Otherwise, these markers will not be replaced. Files which are not started with this “_” will not be
parsed and will be served faster.
•
Subfolders are accepted, though the maximum path length must be limited to 60 characters top (including the
“webserv” folder and the “/” characters).
•
If a valid marker is used with a channel or alarm that does not exist (example: analog channel 130), an
“ERROR” message is returned.
•
If a valid marker is used with a channel or alarm that is disabled, a “DISABLED” message is returned.
•
Whenever you want to display the character “%”, it is advisable to use it doubled “%%”. It will assure that it will
not be misinterpreted with a marker start.
