21. Profibus PA Different from DP All PA devices operate from a DP master
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)

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

This is how the Short Circuit protection works… notice the meter readings.
Device Couplers do not allow the circuit to be completely shorted…therefore remaining devices continue to operate. T

28. Device Couplers Short circuit protection: 15-60mA, fixed / switchable
2,4,6,8,10,12-spur versions
A device can be removed without disrupting communication
Terminator: built-in, switchable, external, or automatic
LED indication of status
Access points for handheld communicators
Entire approvals range available in most cases… Zone 0-1-2, Div 1-2
Compatible with FISCO, FNICO, or Entity
Pluggable screw terminals
IP20 DIN mount and IP67 with enclosure options

29. Device Couplers Trunk Module Power from the trunk to TBus

32. 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.

33. 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 350-1A load
Non isolated versions also available (“power conditioner”)

Type “A” is Preferred cable type according to IEC/ISA standard for new installations
Source: Foundation Fieldbus Wiring and Application Guideline

36. Recommended Maximum Spur Length, m(ft)

37. Cable Connections Typical Connections are discrete to terminal blocks
Some manufacturers offer over molded 7/8” connectors
Most Instrument manufacturers offer discrete and 7/8” connections
