Feature restrictions when the Internet options disable JavaScript
The standard Web pages use HTML, JavaScript, and cookies. If your site restricts the use of
JavaScript and cookies, then enable them for the pages to function properly. If you cannot
enable JavaScript for your Web browser, the features that use JavaScript controls cannot
run.
General
The pages do not update dynamically. You must manually refresh the page with the Refresh
icon to view fresh data.
Diagnostic Buffer page
The Diagnostic Buffer page uses JavaScript as follows:
● Displaying the event details: With JavaScript, you select a row in the diagnostic buffer to
see the details in the bottom section. Without JavaScript, you must click the event field
hyperlink of a diagnostic buffer entry to see the event data in the bottom section.
● Changing the range of diagnostic buffer entries to view: With JavaScript, you use the
drop-down list at the top to select the range of diagnostic buffer entries to view, and the
page automatically updates. Without JavaScript, you use the drop-down list at the top to
select the range of diagnostic buffer entries to view, but you must then click the "Go" link
to update the diagnostic buffer page with the range you selected from the drop-down list.
Note that the "Go" and the event field hyperlinks are only visible when JavaScript is not
enabled. They are not necessary and therefore are not present when JavaScript is enabled.
Module Information page
Without JavaScript enabled, the following restrictions apply:
● You cannot filter the data.
● You cannot sort fields.
Variable Status page
Without JavaScript enabled, the following restrictions apply:
● After you enter each variable, you must manually set the focus to the "New variable" row
to enter a new variable.
● Selecting a display format does not automatically change the data value display to the
selected format. You must click the "Monitor value" button to refresh the display with the
new format.
