The file size limit for HTML files containing AWP command is 64 kilobytes. You must keep

Refreshing user-defined Web pages
User-defined Web pages do not automatically refresh. It is your choice whether to program
the HTML to refresh the page or not. For pages that display PLC data, refreshing periodically
keeps the data current. For HTML pages that serve as forms for data entry, refreshing can
interfere with the user entering data. If you want your entire page to automatically refresh,
you can add this line to your HTML header, where "10" is the number of seconds between
refreshes:
You can also use JavaScript or other HTML techniques to control page or data refreshing.
For this, refer to documentation on HTML and JavaScript.
