WinCC Server and Client at the same time

Server-server communication

During communication between two servers, one server accesses data on another server. One server is capable to access the data from up to twelve other servers or redundant pairs of servers. The server accessing the data behaves as a client in respect of the configuration and operation, except that a standard server cannot be configured.

Each server making access requires a WinCC server license. When the system is being configured, the accessing server must be included in the quantity structure.

You have to create Server Package for each Server and copy it to Server, from which you want to have a look at the others.
In OS Project Editor you maycan your amount of servers (see attachment)
