ISO 10303-221:2007 specifies an application protocol (AP) for the exchange of functional data and their schematic representation for process plants. Functional data includes the functional design of systems and the engineering specifications of system components to be used for subsequent procurement or component design.
IEC 62424:2016 specifies how process control engineering requests are represented in a P&ID for automatic transferring data between P&ID and PCE tool and to avoid misinterpretation of graphical P&ID symbols for PCE. It also defines the exchange of process control engineering request relevant data between a process control engineering tool and a P&ID tool by means of a data transfer language (called CAEX). These provisions apply to the export/import applications of such tools.
IEC 62832-1:2016(E) which is a Technical Specification, defines the general principles of the Digital Factory framework (DF framework), which is a set of model elements (DF reference model) and rules for modelling production systems.
