## 3 Methodology  
To establish the architecture of the immersive DT in an Industry 4.0 environment for process monitoring and control at both plant and management levels, the present work is based on the ISO 23247 standard, which was published in 2021 by the ISO TC 184/SC 4 committee to standardize an architecture framework to support the creation of DTs for manufacturing applications. It should be considered that the type of manufacturing \begin{table}

Table 1: _Cont._supported by ISO 23247 depends on the standards and technologies available to model the observable manufacturing elements. Therefore, it provides an open framework to use different technologies where different domains can be used for the data, i.e., the standard does not prescribe specific data formats or communication protocols. The framework guides the development of a DT and is composed of four application layers [33]. ISO 23247-1: Principles, concepts, limitations, and general requirements for the development of digital twins in manufacturing. ISO 23247-2: Model architecture with reference functional views based on domains and entities. ISO 23247-3: List of basic information attributes for observable manufacturing elements. ISO 23247-4: Technical requirements for information exchange and protocols between entities within the reference architecture. The proposed work implements an architecture of an immersive DT of the industry 4.0 laboratory that is composed of the Festo Cyber-Physical Factory (CPF) and CP-Lab stations, which allows for the monitoring and control of the processes in addition to schedule orders and specifying the configuration of the product from the digital environment. The complete cell phone assembly process must be carried out in the two stations where in the CP LAB, the assembly of the bottom part of the phone is carried out, the plate is added, the elements are added according to the order, quality control takes place through artificial vision, and finally, there is the inventory. In the CP Lab, meanwhile, the top cover is placed, sealed using pressure, and classified according to the user's request.
