Universal solutions with SIMATIC S7 programmable controllers and the ET 200 distributed peripheral system  provide numerous cost-effective variants for a machine retrofit. The precisely scalable modular system offered by Siemens allows specific modernization such as the replacement of distributed I/Os while maintaining the existing controller. Some components of a ten or twenty-year-old machine are simply incompatible with state-of-the-art technology and require special solutions.

One must therefore consider and decide whether a complete update of the electrical equipment of the printing machine is a more reasonable alternative, which would mean that electrical machine components are removed and replaced by state-of-the art technology.
