Summary and relevant links

Distributed systems in WinCC OA allow to connect two or more autonomous WinCC OA systems via a network. Each sub system of a distributed system can be configured either as single-station system or multiple-station system in each case redundant or not redundant. A sub system means in this connection a server on which an Event manager is running on (this means not necessarily a complete project). In a redundant system both redundant running servers are considered as one system.

Each system can process and display data (values and alerts) of other systems. You can also access online values, alerts and history of each system by using distributed systems in WinCC OA ("distributed database"). When you access remote DPEs the data points of the sub systems are not copied to the local system. This means that the data points are not multiplied and you can only access the system when a connection to this specific system exists.
