  3. 3. Page 3Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 PROFIBUS/PROFINET International  PROFIBUS and PROFINET International (PI) is the organisation that is responsible for PROFIBUS and PROFINET.  The largest industrial communications user organisation with over 1400 member companies world wide.  Develops, standardises and promotes the technology of PROFIBUS and PROFINET.  Provides application guides for design, installation, commissioning and maintenance of PROFIBUS and PROFINET systems  Provides standard accredited training that is recognised and respected throughout the world. See: www.profibus.com
  4. 4. Page 4Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 PROFIBUS  PROFIBUS is the world’s leading fieldbus system:  Over 40 million devices installed world wide.  Approximately 3,000 products from over 300 different suppliers.  PROFIBUS has been around for almost 25 years.  Over that period the specification has been extended and refined (in a backwardly compatible way) so that new application areas have been opened up. • High speed synchronised servo applications (Robotics and NC machines). • Functional safety systems (process safety, interlocking). • Operation in hazardous environments (intrinsic safety). • High availability systems (reliability and redundancy). • Etc.
  5. 5. Page 5Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 The PROFIBUS Family PROFIBUS DP - Decentralised Periphery  Low cost, simple, high speed field-level communications.  Generally designed for internal use (cabinet mounting).
  6. 6. Page 6Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 The PROFIBUS Family PROFIBUS PA - Process Automation  Developed specifically for the process industry to replace 4-20mA transmission.  Two-wire connection carrying both power and data.  Generally designed for external use (field mounting).

  13. 13. Page 13Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 Levels of Access  Control  Requires regular cyclic update of process values.  Deterministic timing (not necessarily fast).  The most important – cannot be interrupted!  Monitoring  Not necessarily regularly updated (cyclic or acyclic).  Interruptions can be tolerated.  Engineering  Active only when required (acyclic).  Non-deterministic communication OK.  But must not interrupt the above!
  14. 14. Page 14Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 Class-1 Masters  The Class-1 master is responsible for cyclic or regular data exchange. This provides all process values for control and monitoring.  The Class-1 master must be configured to communicate with the slaves.  Configuration is normally carried out using a proprietary software tool supplied for the PROFIBUS master station.  All PROFIBUS equipment suppliers provide standard General Station Description or GSD files.  GSD files can be read by the configuration tool to provide detailed information on the devices being used on the bus.  GSD files make integration of devices from different vendors in a bus system simple.

  16. 16. Page 16Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 Class-2 Masters  Class-2 masters can be used to access management and engineering information from devices (acyclic data).  This is particularly important in PA systems where extensive device information can be accessed in a standardised way.  Class-2 masters do not need configuration, however, they do need information on the devices that are to be accessed.  This information can be provided in two different ways:  Electronic Device Descrition (EDD) files.  Device Type Manager (DTM) software.
  17. 17. Page 17Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 Profiles  The GSD file provides a simple and standardised method for configuring the cyclic data exchange with the controlling master.  However the organisation of the IO data, its encoding and the device functions are normally in the hands of the device manufacturer and can differ between manufacturers.  A “Profile” is an additional specification for a particular type of device that defines how the data is organised and accessed and the functionality of the device.  Profiles are defined by PI and are vendor independent.
  18. 18. Page 18Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 Profiles  Profiles have been defined by PI for a wide range of devices:  Motor control, Drives and servos (PROFIDRIVE)  All process instrumentation and control actuators. (PA Profile)  Functional safety applications. (PROFISAFE)  Energy efficiency. (PROFIENERGY)  HMI devices, Encoders, Identification systems, Robotics etc. etc.
  19. 19. Page 19Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 The PA Profile  The PROFIBUS PA Profile provides a mandatory specification for all PA devices.  It specifies the organisation of the cyclic data so that the process value for every device is standardised.  The Process Value is always communicated in a standardised format:  Standard floating point format for analogue values.  Standard digital format for discrete values.  Plus a standardised status value which encodes the quality of the measurement (good, bad, usable etc.)  The profile also specifies the organisation of the acyclic data so that standard tools can be used to access this data.
  20. 20. Page 20Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 What is PROFINET?  PROFINET is an open Industrial Ethernet standard developed by the PROFIBUS Organisation.  PROFINET  is completely standard Ethernet (IEEE802.3).  operates at 100Mbit/s over twisted-pair copper or fibre- optic cables,  makes use of TCP/IP and other IT standards for non-real- time communications (i.e. configuration and parameters).  Provides a “real-time” channel for time-critical communications (i.e. process data)  PROFINET is NOT PROFIBUS over Ethernet!  However, PROFINET is well thought out to incorporate the requirements of modern systems based on the lessons learned from PROFIBUS.
  21. 21. Page 21Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 PROFINET PROFINet stack (OSI model): Network 7 - Application Layer PROFINET Application Layer 6 - Presentation Layer 5 - Session Layer 4 - Transport Layer TCP/UDP PROFINET Real-time channel3 - Network Layer IP 2 - Data Link Layer Standard Fast Ethernet IEEE802.31 - Physical layer Non time-critical communication Real-time communication
  22. 22. Page 22Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 PROFINET IO  The TCP/IP channel is used for non-time critical tasks.  Downloading of configuration, parameters,  Diagnostics,  Device management information, etc.  The Real-Time channel is used for time-critical data:  Cyclic process data,  Alarms and critical messages,  Communication monitoring.
  23. 23. Page 23Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 PROFINET IO  Many features that have been developed for PROFIBUS devices have been directly incorporated into PROFINET:  Extensive standardised diagnostics,  Standardised alarm and status information,  Identification and Maintenance functions (electronic instrument face plate),  Time stamping,  Highly deterministic process cycle timing,  Profiles (PROFISAFE, PROFIDRIVE, etc.)
  24. 24. Page 24Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 PROFIBUS DP PROXY PROFIBUS PA INTERBUS-S PROXY PROFINET Other fieldbusses? Integration with Fieldbus
  25. 25. Page 25Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 Some Myths about PROFINET  PROFIBUS runs at up to 12Mbit/s, whereas PROFINET runs at 100Mbit/s. Therefore PROFINET is about 8 times faster than PROFIBUS. NOT TRUE!  PROFINET gives similar performance to PROFIBUS.  PROFINET will replace PROFIBUS in the next five years. NOT TRUE!  PROFINET will replace some PROFIBUS DP devices, but PROFIBUS PA will continue.  Both DP and PA will be supported for many years to come.
  26. 26. Page 26Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 Some Myths about PROFINET  PROFINET is not standard Ethernet NOT TRUE!  PROFINET always uses completely standard Ethernet. It just doesn’t always use TCP/IP protocols – only used for non time critical communications.  PROFINET systems can be maintained by our IT people. TRUE, BUT NOT A GOOD IDEA!  PROFINET is much more than just an IT network. Real time determinism, reliability, device diagnostics and security are all much more important than on IT systems
  27. 27. Page 27Introduction to PROFIBUS and PROFINET, Verwer Training & Consultancy Ltd, September 2013 Functional Safety with PROFIBUS & PROFINET  PROFIBUS and PROFINET also offer safety oriented communication that allows for integrating safety oriented components.  A second 'safety fieldbus' is not necessary.  ProfiSafe V2 can be used in systems that are certified according to IEC61158 to Safety Integrity Level 3 (SIL3).  ProfiSafe is used in a wide range of applications:  Factory Automation, Robotics, Materials storage.  Process Automation, Gas & Oil
