Insert a visualization in the device tree.
Then the Visualization Manager is inserted with the visu types TargetVisuand WebVisu.
In addition, a Visu_Task is also created automatically.

Image AddedImage Removed
Create a new POU named ClientInfo and call it from Visu_Task.

Info
The call of the ClientInfo POU must originate from the Visu_Task because only then is the required client handle passed.

WHILE (pClient := VisuElems.VisuElemBase.g_ClientManager.GetNextClient()) <> 0 DO
    IF pClient^.GlobalData.ClientType = VisuElems.VisuElemBase.Visu_ClientType.WebVisualization THEN
        helper(pClientData := pClient);
        s1 := helper.stIPv4;
    END_IF
END_WHILE

...

Start the project and set a breakpoint in line 6 of the ClientInfo POU.

Image Added
Open a browser and type in the following address: http://localhost:8080/webvisu.htm
After the client has connected, execution is halted at the breakpoint and the IP address can be read.
