• providing a network having a number of data processing units running a MES software for controlling and monitoring a production process operating a number of production components;
• providing a production modeler within the MES software enabled to define a business logic, said business logic comprising a plant model of the production process and the related operating procedures for the production components in a fully graphical environment;
• providing a client application builder within the MES software enabled to provide a native, WEB based graphical user interface for generating cross-functionality graphic screens, said screens forming part of the network as presentation clients and displaying data stemming from the production components and being manipulated by the production modeler, where required;
• enabling said production modeler for additionally defining a presentation logic, said presentation logic operating the cross-functionality graphic screens with respect to their content of the data at the presentation clients;
• and
• enabling said production modeler additionally to update the data at the presentation clients exclusively when the business logic requires the update to the presentation logic.
