NAMUR Working Group 2.6 "Fieldbus" Welcomes Innovations Introduced by PROFIBUS PA Profile V3.02

PA Profil 3.02


In the run-up to publication of the new PROFIBUS PA Profile V3.02, representatives of NAMUR Working Group 2.6 ?Fieldbus? and PI (PROFIBUS & PROFINET International) have discussed significant innovations and given consideration to related user requirements. The innovations of the PROFIBUS PA Profile V3.02 received the full support of the members of Working Group 2.6 "Fieldbus".


Particularly welcomed are the field device integration measures specified for the purpose of simplifying life cycle management. With these measures, PI is taking the lead in satisfying current customer requirements regarding digital fieldbus communication.


Field device integration is made simpler based on the following measures

  • Support for device replacement even after changeover to a new generation
  • Simplified handling of device integration (driver files -> GSD, EDD, DTM)
  • Optimized assignment of driver files to field device versions over the entire life cycle of field devices


Representation of status and diagnostic information according to the categories defined in NAMUR Recommendation 107 "Self-Monitoring and Diagnosis of Field Devices? has been available for PROFIBUS field devices since 2005. In PROFIBUS PA Profile V3.02, this representation is now mandatory for all PA field devices, enabling a simplified vendor-comprehensive and uniform representation of status and diagnostic information.


Another highlighting characteristic of the new PROFIBUS PA Profile V3.02 is the shorter loading and readout times for device parameter sets. This not only allows for faster commissioning and device replacement but also speeds up diagnostic and maintenance work.


NAMUR Working Group 2.6 ?Fieldbus? especially welcomes the measures for checking the compatibility rules during PROFIBUS certification, the user guidelines developed for working with driver files (GSD, EDD, DTM) during the equipment life cycle, and the guidelines for device replacement. As a result, the PROFIBUS PA Profile V3.02 can contribute significantly to reducing the engineering and operating costs associated with field bus technology as well as contribute proactively to minimizing life cycle costs.


The time has come to see if these high expectations are met when the PROFIBUS PA Profile V3.02 innovations are implemented in the field.
