HttpServer User Defined Page Data Refresh

chandra · Post by **chandra** » Sun Apr 07, 2019 7:32 pm

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

Code: Select all

<meta http-equiv="Refresh" content="5">

to your HTML do refresh the page every 5 seconds.

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

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?
