Murof, thank You very much for Your reply .

I have another question now. I am well acquainted with the terms multi-user system, distributed system, everything, but I have one question regarding that topic. 

I am supposed to create a web server now (dedicated web server) but , up until now, all of my clients were of uni-client type, and dedicated web server cannot be installed on the client without its own project. Can I add another client in Simatic manager, and create a client project on the dedicated web server computer in order to publish pictures from 2 servers (with their redundant pair, respectively)?

In case I can, I should generate server data from both servers, import those packages to the dedicated web server client, copy all the scripts from both servers and then publish with prefix?

Your reply is very much appreciated.

Best regards,

Filip
