To allow for the overall visualization of resources processes and products one of the conveyor belt examples was complemented by processes and products Fig. 12 . Fig. 10. Sample pplications Fig. 11. Hierarchy-based sample application 513 Automated production monitoring and control system engineering by combining a standardized data format CAEX with standardized communication OPC UA Fig. 12. Basic image of the sample application for resources products and processes The following paragraphs will outline the workflow applied for engineering within the framework. If a CAEX description is available for the equipment see Fig. 13 it is transmitted to the change management of the production monitoring and control system on the basis of OPC UA. Fig. 13. The engineering framework The provided CAEX data is validated against the CAEX XML schema with respect to structural correctness. Subsequently it can be processed further on the basis of the structure and semantics. For this purpose the mapping based on system descriptions or templates .
