Servers and clients of your choice
Depending on the plant size, up to 18 servers can be employed. In general, the plant is controlled by WinCC (SCADA) clients that access one server or that possess a central view to multiple servers (see also "distributed system"). The clients only require the smallest runtime license (RT128) or complete license (RC128) if you also want to confi gure on the client. This makes it possible to configure reasonably priced operator and configuration stations in a network. You can of course carry out configuration online without affecting the function of the servers and operator stations.
