High Power Trunk: One concept for all applications
Segment Protectors in general purpose and Class I,
Div.2/Zone 2 areas
FieldBarriers in Class I, Div.1/Zone 1/0 areas
Summary
Preferred Partner Solutions
... Emerson considers Pepperl+Fuchs a "preferred
partner" for Foundation Fieldbus projects.
Emerson prefers to use technologies from P+F,
whether internal to Emerson products or as
integrated stand-alone P+F products.

General Purpose
NI and IS protection is done in the field
-Segment Protectors
-FieldBarrier
-Distributed architecture
Reliable Fieldbus Power:
-2 powered FF segments
-Simplex or redundant
-Ext. Advanced P.L. Diagnostics optional
-Robust communication
High Power Trunk:
-Up to 30V/400 mA
-Longer cable runs
-Max. number of instruments
per segment - even for IS
High Power Trunk (HPT) vs FISCO
HPT enables utilization of same DCS and FF segment architecture for both general purpose and I.S. applications
Over 25,000 FieldBarriers installed in the field
HPT eliminates the short-comings of FISCO (Fieldbus Intrinsically Safe COncept)
– High system installation cost
– Reduced FF cable length (1000m max)
– Potentially increased number of DCS H1 interfaces
– Large cabinet space requirements for DCS H1 interfaces, wiring, and FF FISCO power
– Limited power => reduced number of field devices on a segment
HPT supports FF segment power conditioner redundancy, providing load sharing and not requiring “switch-over”
Smaller size in the control room:
– ½ the footprint of a simplex FISCO
– ¼ the footprint of redundant FISCO
Field Equipment
Pepperl+Fuchs Trunk to Spur Couplers
– Segment Protectors for Field Devices on Spurs
in General Purpose Environments or Spurs in
some specific Hazardous Environments
(Zone 2 / Div 2)
– FieldBarriers for Field Devices on Spurs in
Hazardous Environments
(Zone 1/0 or Div 1)

Business Results Achieved
Fieldbus Trunk to Spur Coupling
Reduces project risk during start up and operation
Increases plant uptime
Reduces installation cost when used together with High Power Trunk in hazardous locations
Summary
Trunk to spur coupling solutions like segment
protectors and FieldBarriers are critical to assure a
reliable, error free fieldbus installation
They protect the entire network from a single short
In combination with a High Power Trunk approach,
they can bring the same benefits from using FF in
safe areas to hazardous locations
