This specification describes how process control engineering requests are represented in a P&I diagram. It also defines the exchange of process control engineering request relevant data between a process control engineering tool and a P&I tool by means of a data transfer language (called CAEX). These provisions apply to the export/import applications of such tools. The representation of the PCE functionality in P&I diagrams is defined by a minimum number of rules to clearly indicate their category and processing function, independent from the technique of realization (see Clause 6). The definition of graphical symbols for process equipment (for example vessels, valves, columns, etc.), their implementation and rules for the numbering system are not the scope of this standard. These rules are independent from this standard and can be found, for example, within DIN EN ISO 10628 or ISO 14617. Clause 7 specifies the data flow between the different tools and the data model CAEX.
