What is BS EN 62424 - Automation and process control engineering about?
The main task of data exchange is transporting/synchronizing information from the Piping and Instrumentation Diagram (P&ID) database to the Process Control Engineering (PCE) databases and vice versa.
BS EN 62424 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.
BS EN 62424 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. BS EN 62424 specifies the data flow between the different tools and the data model CAEX.
Note: BS EN 62424 does not cover the definition of graphical symbols for process equipment (e.g., vessels, valves, columns, etc.), their implementation and rules for the reference designation system.
Who is BS EN 62424 - Automation and process control engineering for?
BS EN 62424 on automation and process control engineering is useful for:
- The manufacturing industry
- Process control engineers
- Quality control personnel
- Software companies/IT firms
Why should you use BS EN 62424 - Automation and process control engineering?
Efficient process engineering requires highly sophisticated tools for the different needs of the involved work processes and departments. These engineering tools are normally specialized in process design, PCE etc. Therefore, working interoperability is essential to optimize the engineering process.
The definition of a harmonized interface and data management is a core task to ensure a smooth workflow during the whole project and to guarantee data consistency in the different tools. BS EN 62424 procedures and specifications for the exchange of PCE relevant data provided by the piping and instrumentation diagram tool.
BS EN 62424 provides you with the basic requirements for a change management procedure. A generally accepted technology for machine information exchange, the Extensible Markup Language (XML) is used. Hereby, a common basis is given for information integration.
BS EN 62424 illustrates the information flow for the P&ID and the PCE database reconciliation. The data exchange is done via a neutral intermediate CAEX database, not directly from database to database.
What’s changed since the last update?
BS EN 62424:2016 supersedes BS EN 62424:2009, which is withdrawn. BS EN 62424:2009 includes some technical changes with respect to BS EN 62424:2009. These include:
- Updated definitions and new definitions
- Identification replaced with reference designation
- Updated PCE categories and process functions
- CAEX version 3.0, introduction of: native multiple role support, nested interfaces, life cycle meta information, a separate Attribute library, updated examples,
- Updated electronic data model of the PCE request: new normative attribute library for basic PCE request attributes, new informative extended attribute library for further PCE request attributes, and new informative electronic data model for the PCE request
