The integration of package units in a SCADA or DCS involves considerable manual effort. Various aspects of automation such as faceplates, states of sequences or interlocks have to be reproduced for the visualization and management of the package unit in the master control system. The integration effort can be reduced using existing technologies, which could also be extended to a modular plug-and-produce methodology. An essential precondition for this is a uniform formal quantitative description of various aspects of the package unit and tool chains based on the formal descriptions. This paper will present an approach using the description language EDDL, which is established in the field of field device integration.
