Shutting Down Web Client

Does anyone know a way of forcing a CitectSCADA Web Client to shutdown?

I have an issue with users of the Web Client just minimising their browser and not exiting Citect when they have finished. Therefore we keep running out of Web Client licenses. - Purchasing more licenses just seems to make the users more lazy at exiting when they've finished.

It is easy enough to create a function to detect when a user is not actively using the Web Client. However the Shutdown() function does not work on the Web Client. (This is not documented.)

Any suggestions are appreciated.

Check out this technote in the Aveva Knowledge base:

TN000029114 How Can I Monitor And Remotely Disconnect Web Clients?

(sorry, the forum keeps deleting the technote link)

and this toolbox tool: WebClient Timeout Application

Hi Eric,

Thanks very much for this information.

I contacted Aveva Support about this issue in 2021 as was essentially told it is not possible. The Engineer must have been unaware of this TN.

I appreciate your service here.

Hi Eric,

I have had in issue with IE when the ShutdownLocal() function is called.

A popup is shown where the user must select "Allow" or "Don't Allow". IE will only shutdown if "Allow" is selected, therefore automatic shutdown of the Web Client is not performed.

If the Web Client is shutdown, IE then automatically restarts the Web Client. The following message is displayed:

"A problem with this webpage caused Internet Explorer to close and reopen the tab."

Any suggestions appreciated!

Thanks.

If you can't change the IE protection settings, then how about just playing a Ding sound every few minutes with a popup message asking them to close the client if it's no longer needed so others can use it?
