Released on 30 September 2026, DEXPI 2.0.1 replaces DEXPI 2.0 by fixing a number of findings identified in DEXPI 2.0
DEXPI e.V. announces the publication of the DEXPI 2.0.1 Specification on 30 September 2026. This update fixes a small number of issues in the plant model and reacts to several findings in the process model (especially regarding the systematics of the taxonomy of Process Steps). The always included reference example P&ID was also updated to reflect the DEXPI 2 set of Nozzle classes.
Main Highlights of DEXPI 2.0.1 at a Glance
- Small additions in the plant model regarding TubeBundles at Heater classes and a safety-related specialization of ProcessInstrumentationFunction.
- Improvements to the DEXPI Process Model, setting up the taxonomy of process steps in an even more systematic way and correcting missing/wrong relations
- Reference example updated to make use of the specializing Nozzle classes (AccessNozzle -> e.g. Manhole; InstrumentNozzle -> e.g. for Sensors; ProcessNozzle -> the default piping-related Nozzle)
- All fixes are listed in the Changelog directly included in the Specification.
Collaboration Behind the Release
The new DEXPI 2.0.1 Specification is the result of a focused collaborative effort by the DEXPI Plant SIG, DEXPI Process SIG, and the DEXPI Specification Steering Team. This collaboration ensures that the standard remains aligned with real-world engineering needs while leveraging the collective expertise of the community.
