shorten product time to market. To this end, it is necessary to continuously optimize engineering procedures and the process, and to simultaneously consider new industrial requirements and directives.

Today, many systems and plants must be expanded and mod- ernized to ensure that companies can continue to provide prod- ucts meeting market requirements. However, since the installed basis of hardware, application software and know-how of the op- erating and maintenance engineers represents an enormous value, the safeguarding of investments for companies operating the plants is always assigned a high priority during all modern- ization plans.

Experience has shown that the success of migration is largely determined by providing a technical solution that optimally

matches the customer requirements and the customer’s plant. Minimization of the technical and financial risks together with safeguarding of investments for as long a period as possible are always fundamental aspects. The different lifecycles of the vari- ous system components must also be considered, which cur- rently vary from 5 years for PC-based workstations, 15 years for controllers, up to 25 years or more for input/output components and wiring. Therefore Siemens does not consider its task to sim- ply be the complete replacement of an existing system, but in close collaboration together with customers and their system in- tegrators of an individual, future-oriented solution based on the state-of-the-art SIMATIC PCS 7 process control system - always under the directives:
