SIMATIC WinCC Open Architecture Forum

Dear All,

I have designed an HTML page and I am able to monitor data from the HTTP server but data is updating after pressing reload page button on a browser.

Is there any way to update the data after a few seconds automatically.

you can add
to your HTML do refresh the page every 5 seconds.

If you using 3.16 you can use oaJsApi.js and do a dpconnect.

Hai Mr. Kilianvp

Thank you for your replay, I have tried with that but data is not updating just page is refreshing for every 5 sec as you sed and I am using V3.15

Please give me any other solution.

Dear all,

Please give me any solution to refresh data automatically from the HTTP server, I have checked in the help file of WinCC OA but I have not found any detailed information related to auto-refreshing data from the HTTP server.

I have tried with <meta http-equiv="Refresh" content="5"> this but data is not updating, only page is refreshing for every 5 seconds, please tell me where I am doing wrong.

If the page is refreshing every 5 seconds, then the refresh option works.
With such little information it is difficult to guess what the problem is, so I guess you have to share more information (like your user defined page) to get a solution to your issue.
Perhaps the browser caches the page. Have you added some option to prevent that?
