Manufacturing IT systems are an essential part of modern production facilities. They form a link between the manufacturing equipment and the business process, executing tasks such as planning, controlling and optimizing production processes and logistic flows. In the era of Industrie 4.0, manufacturing systems are becoming increasingly modular. Integrated both vertically and horizontally, they are designed to be user-friendly and real-time-capable. This ensures that the demands placed on tomorrow’s production technology are fulfilled, such as transparency, flexibility and optimization of the production process with regard to time, costs and quality irrespective of the quantities manufactured.
