7.1.2 HTTP Web Server
Typing the datalogger’s IP address into a web browser will bring up its home
page, as shown in FIGURE 7-1. This default home page provides links to the
current record in all tables, including data tables, the Status table, and the
Public table. Clicking on a Newest Record link will bring up the latest record
for that table. It will be automatically refreshed every 10 seconds. Links are
also provided to the last 24 records in each data table. Clicking on a Last 24
Records link will bring up the last 24 records for that table. The Last 24
Records display must be manually refreshed. In addition, links are provided to
all HTML files, all XML files, and all JPEG files in the datalogger.
FIGURE 7-1. Datalogger home page
If there is a default.html file on the datalogger, this will automatically become
the user-configurable home page.
The WebPageBegin/WebPageEnd declarations and the HTTPOut()
instruction can be used in a datalogger program to create HTML or XML files
that can be viewed by the browser. For more information on using these
instructions, see the datalogger manual or CRBasic Editor Help.
FileOpen() and FileWrite() can be used to create HTML pages,
but this requires first writing the file to the datalogger’s USR
drive. It is less convenient, and the page will be only as current as
it is written to the file.
