  21. Technical Basics of Foundation Fieldbus • Bi-directional digital communications protocol used for communication between Foundation Fieldbus devices and the control system • Digital communications and DC-powered network • Increases data to the user for diagnostics and asset management • Consolidates wiring versus standard point-to-point • Provides power and communications over a single shielded twisted pair • FF is more than communications – control in the field via function blocks • Manchester Bi-phase L encoding • Data rate of 31.25 kbps (H1 layer) • Pass token • Devices/Instruments… • Will work between 9 – 32Vdc • 10mA – 20mA avg. • Transmit using current signaling • Receive using voltage signaling

  31. FOUNDATION FIELDBUS POWER SUPPLIES • FF Power supplies are used to provide power to each segment while allowing for isolation between segments. • An integrated filter prevents the power supply from eliminating, or sinking, the superimposed data on the network.

  32. FF-831 Fieldbus Power Supplies • Single channel isolated and multi channel redundant • versions • 1,2,4,8-segment variations • Alarm contact for indication of failures • Advanced bus diagnostics • Built-in terminators • Input 18-30Vdc • Output 14-30Vdc @ 350-1A load • Non isolated versions also available (“power conditioner”)
