Foundation Fieldbus (FF) is one of the leading fieldbuses in Process Automation. Its sophisticated architecture is tailor-made for today's automation systems. Its unique set of features allows for the implementation of true distributed control. The Foundation Fieldbus includes an H1 protocol based on IEC 61158-2 physical layer specification as well as an HSE standard for communication over Ethernet/IP. These features and the possibility for distributed control make the Foundation Fieldbus unique for process control application. The main aim of this workshop is to give you a clear understanding of Foundation Fieldbus and to enable you to specify and design systems using this technology. There has been a surge of interest in Foundation Fieldbus due to the tremendous benefits it provides. This workshop aims to break down the terminology and jargon barriers and to explain Foundation Fieldbus in a simple and understandable way; thus enabling you to apply the technology effectively. more infor

2. FieldBus
• A number of competing standards worldwide
• No internationally agreed standard which the market
has completely accepted
• All standards based on the OSI Model

8. What is FieldBus?
• A smart instrument based system
• Digital data communications
• An internationally and market accepted standard to
effectively replace the ‘old’ 4-20mA standard

9. Real Benefits
• Greatly reduced wiring costs
• Reduced installation and start-up time
• Improved on-line monitoring and diagnostics
• Easier change-out and expansion of devices
• Improved local intelligence in the devices
• Improved interoperability between manufacturers

10. Competing Requirements
• A single bus system seems to be technically
possible...
but what happens if the bus fails?
• Simple field devices require simple ON/OFF
status and are real time (m.secs response)
• PLC’s to SCADA systems require large messages
and update times of 10-100 m.secs

11. Three Network Classes
• Bit (Sensor)
• Byte (Device)
• Message (Field)

12. Another way of looking at the industrial networks:
Sensorbus
• Seriplex
• ASI
• INTERBUSLoop
Devicebus
• Device Net
• SDS
• Profibus DP
• LONWorks
• INTERBUS-S
Fieldbus
• IEC/ISA SP50
• Fieldbus Foundation
• Profibus PA
• HART

13. Bit Oriented Systems
• Binary type switches such as Proximity
sensors/contact closures/float switches
• Example:
Actuator Sensor Interface (ASI)

14. Byte Oriented Systems
• Byte oriented systems such as bar code readers,
temperature and pressure transmitters
• Excellent Examples:
• DeviceNet or CANBUS

15. Message Oriented Systems
• Message oriented systems - PC’s to PLC’s in
uploading system or device configuration
information
• Messages greater than 16 bytes in length
• Examples:
• Interbus-S; Profibus; Foundation Fieldbus
