DEXPI is the German industry initiative to support and promote the ISO 15926 standard for plant data transfer, and it has reached a major milestone: the definition of standard specification covering a complete piping and instrumentation diagram (P&ID). Autodesk, Inc., developed a proof-of-concept application for AutoCAD P&ID software to import/export P&ID data fully implementing this DEXPI specification. In this class, we will illustrate challenges and opportunities of implementing a generic standard for use with industry data and workflows, and we’ll try to answer the following questions: Can one use the current ISO 15926 specification to exchange high-quality data for P&ID data? What is the difference between DEXPI and ISO15926 standard? How are these activities related to the IFC and Open BIM Standards? This session features AutoCAD P&ID.

Digital twins of process plants are digital replicas of the physical plant that contain information of the plant structure and of the dynamics of how the processes and devices operate. In simulation-based digital twins (SBDTs), first-principles simulation models are used to obtain dynamics of the targeted plant. These applications can be used to derive nonmeasured information of the simulated system, to obtain high-fidelity predictions, or to perform system-wide optimization for improving plant performance. This class will present an extension to the work showcased at Autodesk University 2018. In this class, we’ll present a Forge-based SBDT that uses a Model Broker, a novel solution for automatic simulation model generation. Model Broker utilizes the DEXPI information format available from AutoCAD Plant 3D software to generate the underlying simulation model of the SBDT. In the example implementation used in this class, the generated model is connected to the plant using OPC UA.

DEXPI is the German industry initiative to support and promote the ISO 15926 standard for plant data transfer, and it has reached a major milestone: the definition of standard specification covering a complete piping and instrumentation diagram (P&ID). Autodesk, Inc. developed a proof-of-concept application for AutoCAD P&ID software to import/export P&ID data fully implementing this DEXPI specification. In the first part of this class, product and sales development illustrate challenges and opportunities of implementing a generic standard for use with industry data and workflows. In the second part, Bayer AG and Autodesk review the results of exchanging production-grade P&ID drawings solely based on the DEXPI ISO 15926 specification. Can one use the current ISO 15926 specification to exchange high-quality data for P&ID data?

Having a diverse software landscape is common in a global chemical enterprise such as Bayer. There is a vital need to exchange plant data such as P&ID drawings between systems, but often a low-quality exchange has to be followed by time-consuming manual rework. The ISO 15926 initiative aims to define a global generic standard for exchanging plant data. The XMpLant schema provides a widely accepted format to adapt the current ISO 15926 standard for practical use. AutoCAD® P&ID is the first Autodesk program that supports bidirectional data exchange based on ISO 15926/XMpLant. We review the ISO15926 and the DEXPI initiative. We then provide a preview of the new AutoCAD P&ID XMpLant interface. Learn how Bayer, BASF, and others are working with Autodesk and other vendors to evolve the ISO 15926 standard. Using practical application examples from current projects within Bayer, we discuss how Bayer could streamline migration projects and internal P&ID data exchange using this technology.
