4.1.3 Client/server system
The client/server system is a classical SCADA application (Supervisory Control and Data Acquisition).
• A central server, IPC (controller) for data management (alarm, recipe, trend management) is
typical of this application.
• Operation and monitoring of the machine/system can be carried out via an optional number of
client devices.
