Overview
SIMATIC Comfort Panels are used to control the plant areas. A PC station with
WinCC Runtime Advanced installed on it is used in the control center.
The Comfort Panels are parameterized as an OPC UA client.
The PC station is parameterized as an OPC UA server.
All devices communicate via the OPC UA interface. Data integrity through
encryption and digital signatures is supported by the OPC UA communication
interface.
When the application example uses the term ‘PC station’, this always refers to
the "WinCC Runtime Advanced” installation.
