In the food and beverage industry, and also in the production of medicines and cosmetics, excellent hygiene in processes and around the plant plays a key role. This is ensured by stringent legislative regulations. Standards such as HACCP (Hazard Analysis and Critical Control Points) for food processing and GMP (Good Manufacturing Practise) for FDA-compliant processes in the pharmaceutical industry define extremely stringent requirements for cleanliness, safety and product quality. In addition, legislation requires that all processes must be constantly monitored and documented in these areas. In an increasingly competitive global environment, companies of this industry are at the same time forced to make their production processes as efficient and cost-effective as possible, in addition to optimizing processes. As a consequence, there is an ever increasing demand for automation at all process and auxiliary circuit levels.
