Specification
2.1
Overview
The FieldConnex Power Hub is a high performance power supply for
FOUNDATION Fieldbus. It consists of a motherboard with sockets for plug-in
modules and one or two power modules (redundant configuration) per segment.
The Power Hub is designed for use with fieldbus systems in accordance with IEC
61158-2. This standard specifies how power and communication are transmitted
sharing one shielded twisted-pair cable. Communication between field devices
and host system is established by modulating the data signal onto the power
stream utilizing Manchester Bus Powered (MBP) transmission.
All active electronic components are located in the plug-in modules. Each module
holds the electronic components for only one segment and two modules build a
redundant configuration. If required, only the smallest amount of electronic
components needs to be exchanged. Modules can be exchanged while the
system is energized without the use of tools, thus ensuring very high system
availability.
The Power Hub feeds fieldbus segments following the High-Power Trunk concept
for explosion protection. High energy level on the trunk line is fed to the field
instrument via couplers as FieldBarriers or Segment Protectors.
Using Segment Protectors allows you to do live maintenance at the field device in
Zone 2 as outputs are classified Ex nL. Using FieldBarriers allows to do live
maintenance in Zone 1 as outputs are classified Ex ia. Thus, limitations for
explosion protection are overcome enabling maximum cable lengths and highest
number of devices in any explosive area.
2.2
System Components
2.2.1
Motherboards
Motherboards are available in redundant or single configuration, for a different
number of fieldbus segments. Motherboards are typically mounted on DIN rails
inside a wiring or marshalling cabinet. Wiring connectors exist on board for two
independent bulk power supplies, fieldbus segments, fault and diagnostics
signalling.
All motherboards contain the unique, patented CREST technology thereby
creating high impedance for common mode noise and network resonance effects.
FBTA-228-BPFB-R-4R
The motherboard is designed for use with INVENSYS FBM 228 FOUNDATION
Fieldbus modules and allows the redundant supply of four fieldbus segments.
Eight sockets will hold the power supply modules, two each are in redundancy per
segment.
184307 2011-06
FBTA-228-BPFB-8
The motherboard is designed for use with INVENSYS FBM 228 FOUNDATION
Fieldbus modules and allows the supply of eight fieldbus segments. Eight sockets
will hold the power supply modules.
7
FIELDBUS POWER HUB INVENSYS
Specification
2.2.2
Modules
Power Modules are connected to the motherboards via sockets. Replacement
under live conditions (hot-swap) and load sharing capability in redundant
configuration enable uninterruptible communication. The modules are available in
different explosion protection configurations and with various isolation levels.
■
Power Conditioner Modules
Modules with current limiting circuits between bulk power supply and
fieldbus segment and without galvanic isolation are called "Power
Conditioner Modules". Power Conditioner Modules carry passive
components only and can be used if good wiring practice is followed and
reduced safety requirements exist, such as protection type n or increased
safety. Power Conditioner Modules utilize CREST technology creating high
impedance for common mode noise reduction and network resonance
suppression.
184307 2011-06
■
Power Supply Modules
Modules providing full galvanic isolation between bulk power supply and
fieldbus segments are called "Power Supply Modules". They provide
optimal system reliability for applications where cabling and wiring are
routed through critical or harsh electrical environments, i.e. where superior
protection from electromagnetic interference (EMI) is mandatory. Different
Power Supply Modules exist with voltage regulated and limited energy
levels according to the specifications of FNICO, Entity and FISCO
standards. A maximum output current of 500 mA is available to power field
devices.

Prevent Grounding Loops
You can leave the shield earthing at the host connecton open, depending on the
selected grounding method. If the grounding points of the host and the field
devices do not have the same potential, the shield of the motherboard must be left
open to prevent a grounding loop.
Caution!
This is not a safety earth.
Under certain conditions, it may be necessary to ground any exposed metal parts
to ground.
Note that a correct grounding must be guaranteed at all times.

Motherboards got integrated terminators for each fieldbus segment.
Caution!
Communication Problems
Wrong termination may cause communication problems or a total communication
loss.
■

3.5
Make sure that there are two terminators activated on each trunk line.
One terminator should be located on each end of the trunk line.
Addressing and ID Switch Settings
The addressing of the Fieldbus Power Hub motherboards and the FBM is based
on the principle of FOXBORO's baseplates. For further information, please refer to
the corresponding INVENSYS/FOXBORO User Guide: "I/A Series – DIN Rail
Mounted FBM Subsystem (B0400FA)".
For connecting to the Ethernet bus or for traversing relatively large distances, the
Fieldbus Power Hub motherboards must be divided into a maximum of four
groups, each with a maximum of eight stations. This corresponds to four nonmodular baseplates from FOXBORO, each with eight modules of type FBM.
Each motherboard has an ID DIP switch array with five switches. You can adjust
the number of the group with the first two switches.
The switches 3 to 5 control the adressing of the motherboard within the group.
The motherboards can be numbered according to their physical placement in the
enclosure, or according to their position in the cable connection schema.
184307 2011-06
Each ID number must be used once only. The Fieldbus segments must be
subdivided into groups of no more than eight stations each.

Electromagnetic Compatibility Verification in Accordance with EC
Council Legislation Directive 2004/108/EC
Compatibility in accordance with EN61326-1:2006 and Namur NE21:2006
recommendation.
The electromagnetic compatibility – EMC – requirements applicable for electrical
equipment for measurement, control and laboratory use in general are anchored
in the European Standard EN 61326. Three different performance criteria are
distinguished in this standard:
A category A device operates as intended during the test. This device can
withstand the immunity tests without any noticeable performance degradations
within the specification limits of the manufacturer.
A category B device operates as intended after the test. The device shows
temporary degradation or loss of function of performance during the test but selfrecovers from that state when the exposures are ceased.
The requirements of the association for standard and control and regulations of
the German chemical industries, defined in the NE21 recommendation, are partly
higher compared to the test levels and failure criteria defined in EN61326-1. For
the product qualification, failure criteria and test levels have been selected,
representing always the worst case conditions.

A category C device has loss of function, may need manual restoration. During
the test a temporary loss of function is allowed as long as an operator can restore
the device back to operation.
