Configuration of a distributed SCADA system
A multi-user system is used whenever the same process is to be monitored at several operator stations. When the Option is used, several operator control and monitoring stations are coordinated to operate together with networked automation systems. The server supplies the connected clients with process and archive data, messages, pictures and logs. The result of an operator action at one operator station, for example, changing a value or message acknowledgment, is immediately available to all other operator stations.
Integrated scalability from the single-user system to the client/server solution
Economic solution for SCADA applications with higher complexity
Configuration of distributed operator stations with little effort
Configuration of distributed client/server systems with up to 18 WinCC servers.
Clients provide access to all servers in the system
Configuration of clients as remote Web servers
Low-cost configuration on the client
Design and functions
The server establishes the connection to the automation system, handles the communication and coordination of the clients, and performs all archiving in the integrated Microsoft SQL database. WinCC clients access the configuration data of the server directly. Access rights are used to define the functions or plant sections that are available to a user on an operator station. The configured authorizations are user-related, not computer-related. They therefore work with all operator stations with the same login.
The following licenses are required for configuring a multi-user system:
