ClearSCADA's web interface, WebX, uses Microsoft’s ActiveX Controls technology to display Mimics, Lists, Trends, and so on. ActiveX Controls are only supported by Microsoft Internet Explorer; as such, the WebX client supports the 32-bit version of:
- Internet Explorer 10
- Internet Explorer 11.
(ClearSCADA's Original WebX client also supports Internet Explorer 8 and Internet Explorer 9.)
WARNINGUNEXPECTED BEHAVIOR OF APPLICATION (INTERNET EXPLORER 9 and 10)
There is a known issue with Internet Explorer 9 and Internet Explorer 10’s Cross-Site Scripting (XSS) Filter that can cause these versions of Internet Explorer to ‘hang’. This only applies when:
- Using an Original WebX client (rather than a WebX client) to access a ClearSCADA server
- Using IE9 or IE10 to connect to ClearSCADA over the Internet
- Using IP addresses in the URL for the ClearSCADA server
- The default security settings for the Local Intranet zone have been modified.
For more information about this issue and instructions on how to prevent or correct this issue, see Internet Explorer 9 and Internet Explorer 10 XSS Filter Issue - ‘Hanging’.
