21 Different from DP –BUS Speed 31.25Kb/s –Physical layer same as Foundation Fieldbus All PA devices operate from a DP master –Connected via a linking device Logical communication the same as DP –Master(s) / Slave (Poll – Response) Profibus PA

22 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 kbps (H1 layer) Pass token Devices/Instruments… –Will work between 9 – 32Vdc 10mA – 20mA avg. –Transmit using current signaling –Receive using voltage signaling
