The international competition leads manufacturers in high-wage countries to focus more on high-value products, which often come at the disadvantage of small batch sizes. To remain competitive, the plant engineering for should be time and cost effective. One approach to achieve this are modular production lines. In the presented contribution, a product orientated web- service for the configuration of a modular production plant investigated. The resulting model then is interpreted by a code generator to generate a PLC line control. The approach is validated with a plant of metal hybrid carbon fiber seat rests.
