This document describes an approach to support an automated generation of simulation
models by use of already existing engineering data. The concept enables engineers to
execute tests in parallel to the development of the control applications, using a physical
model of the controlled system. The simulation model forms a virtual representation of the
process plant that is still under construction at that time. Both simulation approaches,
Hardware-in-the-loop (HIL) or System Simulation, can be applied with varying intensity
during the test phases. The piping and instrumentation diagram (P&ID) as an essential
design document within engineering processes serves as the data source for model generation.
Nowadays, P&IDs are still exchanged between the different project partners on a paper base
or portable document format (PDF) respectively. Thus a computer-aided further processing is
not possible. In this context the authors use and extend an XML-based data exchange format
to export all information from the P&ID that is required for the generation and parameterization
of a physical simulation model. With this approach, the object-oriented structure available
in some of today's computer aided engineering (CAE) tools can be transferred into a generic
representation and be re-used for automatic model generation.
