DEXPI 2.0: Synergistic Integration of PFD and P&ID in a Unified Digital Model

DEXPI 2.0 is designed to combine PFD and P&ID in an overarching model, while keeping the important distinction between process and plant elements. This short communication, based on the PEMT 2024 presentation, describes the motivation for going this way with the DEXPI specifications and gives an outlook to future integration mechanisms in DEXPI 2.x.

Abstract

With DEXPI 2.0, the DEXPI association aims to release its specifications for BFDs/PFDs (DEXPI Process) and P&IDs (DEXPI Plant) in one overarching package the first time. This comes with a new simplified serialization and handover format being extensible for future needs and use cases. This short communication based on the PEMT 2024 presentation names the main motivating vision for going this way with the DEXPI specifications: “seamless information handover from simulation to PFD” and “integration of PFD with P&ID”. As an outlook, ideas about the future mechanisms allowing explicit information integration with DEXPI 2.x are sketched.
