Troubleshooting
Browser Security Settings
To use FactoryTalk Historian ActiveView, users need to be able to run
ActiveX controls on the HTML page. This ability may be prohibited if the
user's PC has excessively restrictive security settings.
To view security settings in Internet Explorer:
1. Choose Tools > Internet Options.
2. In the Internet Options dialog box, click the Security tab.
3. Click Custom Level. In the Security Settings dialog box, you can set
a general level, from Low to High, or adjust the custom settings. In
general:
 If security settings are High, you may get a message stating that
ActiveX controls are not allowed and the FactoryTalk Historian
ActiveView content on the page does not appear.
 If security settings are Medium, the page and ActiveX controls
appear.
Displays and Connection Failure
If the connection to your data is not successful, the display is still drawn,
but data in dynamic elements are replaced with indicators signifying that
no data is available.
