Presentation Transcript

  1. PROFIBUS • The world’s leading fieldbus • Tanner Payne • 23 November 2009

  2. Current State • Profibus is worlds most successful fieldbus • PROFIBUS DP (Decentralized Peripherals) • Operate sensors and actuators via a centralized controller. • Data rates up to 12 Mbit/s on twisted pair cables and/or fiber optics are possible. • PROFIBUS PA (Process Automation) • Monitor measuring equipment via a process control system in process engineering. • Low voltage when used in flammable processes. • The disadvantage of this variant is the slower data transmission rate of 31.25 kbit/s.

  3. Current Expansion • 10 million in 2004 • 20 million in 2007 • 30 million October 2009 • 50 million by end of 2012 • Groups like • Profibus Trade Organization (PTO) • Profibus International (PI)

  4. Who Benefits • Openness and standardization guarantee the supply of PROFIBUS products from many different vendors as well as the availability of know-how and support from many different experts close to you. Work proceeds as about 400 engineers in 40 Working Groups continue to advance the state-of-the-art, adapting to the ever-changing automation landscape. • Softing North America

  5. What • The PROFIBUS data transport is by a two-core twisted pair cable to connect network stations such as PLC's, variable-speed motor drives, intelligent terminals and PCs. • The standard interfaces which are provided guarantee trouble-free and fast communication without addition programming effort. PROFIBUS minimizes the installation with standardized and user-friendly protocols. • Even if one or more stations should fail, the other stations and the bus itself continue to work correctly. If a faulty device needs to be replaced, it is only necessary to set the station address and connect up the new device to the network - configuration takes place automatically online.

  6. Where Used • Cummins engine assembly UK • Electric Monorail System • PROFIBUS DP networks in the system, providing communication to RFID devices, HMI operator panels, maintenance touch panels, LJU carrier controllers and distributed I/O. These networks are also used to interface between the S7-317DP PLC’s which control the system.

  7. Where Used • Coca-Cola Bottling Plant at HM Interdrink (Germany)

  8. Watson Marlow Pumps Group • The world's first PROFIBUS-enabled NEMA 4X peristaltic pumps

  9. Watson Pump • http://www.youtube.com/watch?v=TumlDDDS_Q0

  10. Cost • $5 for cables and IO blocks • $2000 for Controller cards • Example $130 USD • Siemens Micromaster 420, 430 and 440 Profibus Module. Allows remote connection of Micromaster series drives at up to 12 Mbaud via Profibus network

  11. Supporting Technology • A PLC, computer, and software are needed to run a PROFIBUS system.

  12. Rules and Limitations • Repeaters for distance • 1 m minimum distance between nodes

  13. Primary Vendors

  14. Existing or evolving standards • PROFINET, a more powerful and broader offering than PROFIBUS. IT is based on an enhanced version of the Ethernet used in offices, and is therefore a future-oriented network solution that embraces PROFIBUS - and other fieldbuses - easily as well a integrating tightly with IT systems and making enterprise management more efficient. • Active Energy Management aimed at using PROFINET to help reduce industrial power consumption has recently been launched.

  15. Class application • Should the conveyor lab be upgraded to Profibus?
