This case presents the DEXPI OPC UA specification as an enabler for dynamic exchange of P&ID information to the next steps of the system design lifecycle and to subcontractors who are interested in parts of the process or in specific equipment (see Figure 7).


Figure 7 - Secure data handover between design and system lifecycle phases and between owners and subcontractors can be facilitated by the DEXPI OPC UA specification

The OPC UA server can always have up-to-date P&ID data and other project stakeholders (e.g. subcontractors) can view/edit them (if they have the access rights).
