Is it possible to connect more than one device to WinCC Unified at the same time? I would like to have a main monitor and additionally connect eg mobile phone.

If I open the website on the first computer everything works, but if I try to open it on another computer until I first one is running, I get the message "No connection to server Automatically reconnect in ... second (s)"

As mentioned it is possible.  Make sure all certificates are setup correctly.

@LirumLarum:
Yes, it works when first client is not connected

@Rameymm:
I have tried to install the entire certificate but have to install one by one. It was a point.

Right now I can connect 2 clients at the same time but not more. I have license WinCC Unified Client - 3 Operate Clients. Should I change something to use it? It's normally visible in License Manager...

 Hi Kojot50,

Did you manage to have more than 2 clients at the same time? Where do you set it up to enable more than 2? I understand the license requirement but do you set the number of max client in the run time setting?

Hi,

you do not have to set the maximum of Clients possible. I think this problem here is a network/infrastructure problem.

You need to access the Webserver with the same identity as on the other Clients. Typicly the computername if you have a DNS.

The already mentioned FAQ should mention this, what to do if no DNS is available.

 Hi ZickZackTIA,

I have one running in the localhost and also I have two iPad. But at one time, only one iPad can access the server. 

Maximum clients at one time as I can see is only 2 clients. How can we have more clients? Eg. 2 iPads with 1 localhost client running?

Did you manage to solve this?

I am having the same issue

I also had this problem, i could not connect more than 2 clients to the WinCC Unified PC Runtime.

The Wincc Unified PC RT was installed on Windows 11 Home, when I switched to Windows 11 Pro i could connect more than 5+.
