For over two decades, the SIMATIC S5 was successfully used in the process industry and in manufacturing automation as a complete controller family for a wide range of controller tasks. Many SIMATIC S5 control systems are still in reliable service today, but rapid technological changes and increased market demands place stringent requirements on the automation system of today and tomorrow. A migration from SIMATIC S5 controllers to SIMATIC S7 is therefore always a wise decision. However, an upgrade to a DCS might perform better depending on your application. For these circumstances the "Totally Integrated Automation" (TIA) concept of Siemens offers a lot of interesting possibilities.
