Furthermore large sets of simulated data are also a necessary ingredient for the development of surrogate models for faster and more accurate simulation, reduction and analysis of the data. The development of a digital twin of an instrument can answer such different needs with a single unified approach wrapping in a user-friendly envelop the knowledge about the instrument physical description, the specific of the simulation packages and their interaction, and the high performing computing setup. In this article we will present the general architecture of the digital twin prototype developed at the ILL in the framework of the PANOSC European project in close collaboration with other research facilities (ESS and EuXFel). The communication patterns (based on ZQM) and interaction between the control system (NOMAD), simulation software (McStas), instrument description and configuration, process management (CAMEO) will be detailed. The adoption of FAIR principles for data formats and policies in combination with open-source software make it a sustainable project both for development and maintenance in the mid and long-term.
