Web Server Connections

[jiji.thankappan]

Hi all,

Could you please advise, how many WebServer connections are possible a WinCC OA Server? Is there any limitations?

[leoknipp]

The number of possible connections is related to the amount of data which needs to be processed by the CTRL manager starting the httpServer() function.
How many parallel connections do you want to use?
What is the httpServer() functions used for?

Does WinCC OA will comply for unlimited number of WebClients? As i know a single webserver will support only 30 number of webclients. So what will be the calculations if there is possibility of unlimited webclients?

What is a "WebClient" in your question?
Is it a WinCC OA UI?

Yes, Ultralight client (ULC UX)

[leoknipp]

An Ultralight UX client is also a UI. When using ULC UX for every ULC UX client a UI will be started on the computer where the web server is running.
In WinCC OA you can start up to 254 UI manager at the same time. This number of UI clients includes all UI types: Fat Client UI, Desktop UI, Mobile UI, ULC UX.

An unlimited number of web clients (ULC UX) is not possible.
The number of UI clients is limited by the WinCC OA license used in your project.

If the computer where the web server is running is running out of ressources you can use additional computers where WinCC OA is installed to use them as web server for the same project.
