SIMATIC WinCC Open Architecture

SIMATIC WinCC Open Architecture - The SCADA system without limits
SIMATIC WinCC Open Architecture is a SCADA system for visualizing and operating of processes, production flows, machines and plants in all lines of business. Distributed systems enable any number of stand-alone systems, from 2 to 2048, to be linked via a network. 
Each subsystem can be configured either as a single-user or multi-user system, redundant or not, in each case. SIMATIC WinCC Open Architecture relies consistently on object orientation for process images and the database structure.
