Based upon experience gained as the largest HMI vendor in the world, Siemens offers a comprehensive HMI software solution to address your complete operating, monitoring, and business integration needs – SIMATIC WinCC.
All HMI functions on-board
A complete range of functionality is provided as base features of the WinCC system for graphically visualizing process operation and status conditions, reporting and acknowledging events, archiving measured values and messages, logging process and archive data, and user management and access control. The system continuously records sequences and events that are relevant to production which makes it possible to insure quality on an ongoing basis. Scalable architecture, from a single user to distributed multi-user SCADA system 
The architecture of WinCC can start with a simple single-station / single-user HMI and grow to a multi-user plant-wide supervisory system supporting tens of thousands of tags.
A sophisticated client-server approach enables distributed operator stations, even allowing for redundant high-availability systems. Web-based thin client stations offer full operator station functionality anywhere on the LAN or WAN. SIMATIC WinCC is a powerful platform for IT and business integration. With integrated historian functionality based on Microsoft® SQL 2000 Server, WinCC enables information integration from the simplest single stations through plant-wide multi-user systems, including redundant servers. Siemens SIMATIC WinCC Software enables your vision into the manufacturing process by
- Capturing real time & historical data on production, quality and downtime
