SIMATIC WinCC Open Architecture is an open SCADA system with comprehensive drivers and flexible connection possibilities for other external systems. Depending on the communication protocol and the used bus physics, in each case specific drivers are used.

You can run several drivers simultaneously in SIMATIC WinCC Open Architecture. These can be of the same but also of different type. Therefore, you can establish connections to a SIMATIC controller by means of the S7 protocol, by means of the IEC 60870-5-104 to a telecontrol system and through OPC DA to an arbitrary OPC server.
