Profibus International is an industry association founded to promote and maintain the PROFIBUS and PROFINET standards for industrial automation. It coordinates technical committees, certification programs, and market outreach to support interoperable fieldbus and industrial Ethernet solutions across sectors such as manufacturing, process control, energy, and transportation. The association works with standards bodies, equipment manufacturers, system integrators, and research institutions to align specifications, testing procedures, and training materials.

History

Profibus International traces its origins to collaborative initiatives in the late 1980s among German automation firms and research institutes, emerging alongside developments at Deutsche Forschungsgemeinschaft, Siemens, ABB Group, Bosch, Phoenix Contact, BASF, Bayer, Volkswagen, Siemens AG, Infineon Technologies, Schneider Electric, Honeywell International, Emerson Electric, General Electric, Rockwell Automation, Mitsubishi Electric, Yokogawa Electric, Hitachi, FANUC, KUKA, NXP Semiconductors, Texas Instruments, Intel Corporation, IBM, ABB Ltd, Beckhoff, Turck, Endress+Hauser, SICK AG, Lenze, Rittal, WEG S.A., Mitsui, Mitsubishi Heavy Industries, ThyssenKrupp, Siemens Energy, Boeing, Airbus, Siemens Healthcare, Johnson Controls, Legrand as industrial digitization accelerated. The early work drew on laboratory projects at Fraunhofer Society, Technische Universität München, RWTH Aachen University, and Karlsruhe Institute of Technology where fieldbus research intersected with automation curricula. As international interest grew, the association established liaison relationships with International Electrotechnical Commission, International Organization for Standardization, European Committee for Electrotechnical Standardization, OPC Foundation, Fieldbus Foundation, Modbus Organization, EtherCAT Technology Group, PROFIBUS Nutzerorganisation Deutschland, PLCopen, ISA (International Society of Automation), VDE, ZVEI, BITKOM, DIN, CENELEC, IEC 61158, and IEC 61784. Major milestones included publication of protocol profiles, release of conformance test suites, and rollout of certification labs throughout Europe, North America, Asia, and Australia.

Standards and Technology

Technical work focuses on real-time communication protocols, application profiles, network management, safety integration, and industrial Ethernet transition. Key protocol documents relate to IEC 61158 and IEC 61784 series and interoperability with IEEE 802.3 physical layers, while alignment efforts coordinate with OPC UA, PROFINET, Modbus, EtherNet/IP, EtherCAT, CC-Link, DeviceNet, CANopen, AS-Interface, FOUNDATION Fieldbus, HART Communication Foundation, and BACnet. Security and safety projects reference standards from ISO/IEC 27001, IEC 62443, IEC 61508, ISO 13849, and IEC 61511. Hardware and software components include integrated circuits from NXP Semiconductors, Texas Instruments, STMicroelectronics, Microchip Technology, and Infineon Technologies, and field devices produced by Endress+Hauser, Siemens AG, ABB, Emerson Electric, Schneider Electric, Honeywell International.

Product Certification and Conformance Testing

The association operates certification schemes and authorized test laboratories to validate conformance, interoperability, and protocol compliance. Accredited test houses coordinate with national accreditation bodies such as Deutsche Akkreditierungsstelle, UKAS, ANAB, JAB, and CNAS to ensure laboratory competence. Certification labels are recognized by OEMs, system integrators, and end users across sectors including Automotive Industry, Petrobras, Royal Dutch Shell, ExxonMobil, TotalEnergies, Siemens Energy, Siemens Gamesa Renewable Energy, ABB Power Grids, Schneider Electric Grid Solutions, and GE Power for guaranteeing device interoperability in control systems designed by Emerson Process Management, Honeywell Process Solutions, Rockwell Automation.
