and Knowledge
 The Fieldbus is here, it could be put to use.
This was the initial thesis for the very thorough
study FuRIOS which was conducted in 2002 by
major users of process automation technology.
And the resuIt is: fieldbus offers a lot of benefits
over the current technology, such as advanced
diagnosis, less downtime, increased quality,
reduced Process C&I points due to multi-variable
devices.
Together with a sophisticated, comprehensive
installation concept it even allows savings in
the investment costs, quite unusual for such a
technological generation leap.
FieldConnex offers these installation concepts
to optimize the live cycle costs of your plant,
increase the reliability of your Process C&I and

Topology Concepts
Depending on the level of explosion hazard, FieldConnex
allows to tailor the topology exactly to the requirements
of your specific plant.
The following examples show the basic Power Supply
Concepts, following the general recommendation of
keeping a clear, straight-forward structure with one
trunk per fieldbus segment and connecting the field
devices to this trunk by means of fieldbus distribution
modules. In order to gain the optimum benefit in terms
of plant availability and long-term live cycle costs, each
field device should have its individual connection point

The above picture shows the typical fieldbus topology
for non-hazardous environments. The FieldConnex
system offers several versions of Junction Boxes to
connect the field devices to the trunk, with connection
points from one through eight field devices per box.
Since the reduction of cables offers a major cost saving
possibility the choice of the Junction Box and its
location as close to the field device as possible allows
to minimize the lengths of the drop lines.

One possible problem of fieldbus systems is the dan-
ger of a complete communication break-down in case
of faults at one of the connected devices.
To prevent the negative feedback of a short-circuit at
one drop line, FieldConnex features an advanced field-
bus distribution module under the name Segment
Protector. The following picture shows a topology
sample using Segment Protectors.
In such a topology only the faulty spur will be out of
the communication, the remaining segment will keep
on working. Thus it is easy to locate the faulty device
and quickly fix the problem.

Function
The FieldConnex"! Fieldbus Power Supply and Fieldbus Power Conditioner are designed to supply
FOUNDATION Fieldbus H1 devices with sufficient operating power via the fieldbus network. They couple the
supply power onto the 2-wire fieldbus cable without impairing the digital fieldbus communication signal.
The Fieldbus Power Supply supplies a constant voltage independent of the load and input voltage and is
equipped with a fieldbus terminator on the field side. To facilitate simple installation, the device has removable
terminals and a Power Rail connection, thus eliminating the need for wiring and daisy chaining of power
supply lines.
The Fieldbus Power Conditioner delivers a supply current of up to 1 A to the connected field devices via the
fieldbus cables. It conditions standard (bulk) power supply for integration with the digital fieldbus signals.
The Power Conditioner incorporates a passive design to power the fieldbus network, resulting in extremely
high reliability. Redundancy for the bulk power supplies is supported.
One or more Power Conditioners can be mounted on the same Power Rail and connected to the bulk power
supply by means of a Power Feed Module. Each Power Conditioner supplies power to one FOUNDATION
Fieldbus Segment. In case of redundant bulk power supplies two Power Feed Modules are used.
Power Conditioners and Power Feed Modules support alarming and indication of power loss, power supply
failure, under-voltage, short-circuit and overload. A collective fault message can be transmitted to the host
system by separate connection.
Furthermore the Power Conditioner comprises a built-in, switchable fieldbus terminator, two LEDs for power
and fault indication as well as removable terminals for easy installation. Due to its passive design the Power
Conditioner operates with high efficiency, thus creating very low heat
dissipation.

Function
FieldConnex"! Fieldbus Power Repeaters supply field devices via the communication cables of a FOUNDATION
Fieldbus H1 network and improve the digital communication signals within the system. Power Repeaters deliver
a constant voltage for supplying field devices independent of load and input voltage. They refresh the signal
shape and the level of incoming and outgoing digital communication.
Up to 31 repeaters can be located in the same fieldbus network operated by one host. Each Power Repeater
opens a new fieldbus segment. Depending on the type of Power Repeater and the actual current consumption
of the devices from 1 through 31 field devices can be connected to that fieldbus segment. Furthermore the
Power Repeaters separate the fieldbus segments galvanically from each other or the fieldbus host.
Another application for using Power Repeaters is the extension of the fieldbus network. A fieldbus segment
allows for a maximum possible cable length. Since every Power Repeater opens a new segment the total
possible cable reach is multiplied.
The Power Repeaters have two integrated fieldbus terminators. One is fixed, thus opening a fieldbus segment,
the second one is switchable to allow the connection of either host or fieldbus segment.
Removable terminals and integrated Power Rail connections ensure flexible and easy installation, the latter
eliminating the need to wire and daisy chain the power supply and fieldbus lines.
Power Repeaters are available in four versions. Besides the high-power version for general purpose
applications there are versions for applications in hazardous areas. These differ in the explosion protection
method which is either based on FNICO for Zone 2 / Class I, Div. 2 applications or, for Zone 1 / Class I, Div. 1
applications, on FISCO or the Entity model. All Power Repeaters for hazardous area applications can be
installed in Zone 2 resp. Class I, Division 2 of a hazardous area.

Fieldbus Distribution
The recommended communication topologies for FOUNDATION Fieldbus H1 are clear, easy-to-manage tree or
chicken-foot structures. Each field device should have its own connection spur to the trunk of the fieldbus
segment. Thus a faulty device can easily be located and the disconnection of a device does not have any
influence on the communication of the remaining devices.
FieldConnex"! Fieldbus Distributors are available in a huge variety of housing and cable connection types.
In conjunction with various numbers of connection points per distributor this allows the flexible planning of
the topology exactly to the requirements of the respective plant. The distributors allow the implementation of
several shielding and grounding concepts.
Junction Boxes
FieldConnex"! Junction Boxes are available for applications in hazardous areas and for general purpose
applications. The latter feature an integrated, switchable fieldbus terminator. Besides the connections for
looping-through of the trunk they offer connection points for 1 through 8 spurs. Various types of screening
can be employed.

FieldConnex"! Segment Protectors offer, on top of the functionalities of Junction Boxes, short circuit current
limitation and overload protection for each spur. This ensures that a fault at any spur does not have any nega-
tive feedback on the remaining segment. The unaffected devices continue communicating and the faulty spur
can easily be located. The short circuit is indicated by LED, and after rectification of the problem the Segment
Protector resets automatically so the spur resumes operation as normal.
For chicken-foot topologies Segment Protectors are available with connection points for up to twelve spurs,
too.

The FieldConnex"! FieldBarrier is a highly sophisticated fieldbus distribution module and combines three
essential physical layer functions:
Distribution of the fieldbus trunk to up to four connection points for field devices
Short circuit limitation for each individual device connection
Use of the comfortable explosion protection method  Intrinsic Safety for the field devices.
The FieldBarrier is the central element of the future-proof Fieldbus Barrier Power Supply Concept. It allows to
utilize the benefits of intrinsically safe field devices while doing away with the limitations in terms of supply
power and topology size one typically encounters in hazardous areas.
The power for the field devices is fed into the fieldbus segment by standard fieldbus power supplies without
energy limitation for explosion protection. The trunk cable leading into the hazardous area can be installed in
explosion protection method  increased safety Ex e or Div. 2 wiring methods.
Several FieldBarriers can be daisy-chained on the trunk, each one offering four outputs to connect field
devices in explosion protection method  intrinsic safety Ex i. This allows to service the field devices without
the need for a hot work permit. Each output provides 40 mA supply current and is in accordance with FISCO
and Entity concept. Up to 120 m of cable can be connected to an output and operated without an individual
fieldbus terminator.
A fault at one output line has no negative influence on the trunk or the other outputs due to the individual
short circuit and overload protection of each output. The fault is indicated by LED, an automatic reset resumes
the normal operation of the output line after the problem is fixed.
The design of the FieldBarrier ensures high reliability and long-term secure operation. To meet the various
requirements of all the different applications, even in harsh environments, the FieldBarrier is available in most
housing variants mentioned with the FieldConnex"! Junction Boxes.

Function
The FieldConnex"! Valve Coupler is designed to connect low-power solenoid valves to a FOUNDATION Fieldbus
H1 segment. Four valves can be controlled by one fieldbus address. The valve coupler translates the digital
fieldbus signal to a binary output signal for actuation of the valve and vice versa integrates the end position
detection from the valve s proximity switches into a fieldbus telegram. The 2:1 wiring method is used for
wiring the end position indicators which enables further savings on cables.
The Valve Coupler can be installed close to the valves in Zone 1 / Class I, Div. 1 of a hazardous area.
The valves themselves can be located in Zone 0 / Class I, Div. 1.
Power is supplied to the Valve Coupler via the fieldbus cable, which is also used for data exchange, all
parameter assignments, alarms and return messages. No additional devices or wiring are needed.
In accordance with the fieldbus philosophy, monitoring and diagnostic measures are included in the field
device. The Valve Coupler automatically monitors the runtime and breakaway time of the valve, conducts
stroke tests in either valve position, records lead breakage or short circuits on the binary signal cables and
generates alarm messages.
Furthermore it enhances the plant availability due to galvanic isolation between the fieldbus segment and
each valve connection point.
The Fieldbus-Pneumatic Interface is a system solution out of the FieldConnex portfolio, combining the Valve
Coupler with solenoid and amplifier valves in one convenient housing. The only required connections on the
supply side are the FOUNDATION Fieldbus H1 and the pressure air line. The connection to the heavy-duty
pneumatic control valves is done quickly and easily by just attaching the pneumatic hoses and binary signal
lines to the pre-fabricated connection points.
The Valve Coupler forms the communication interface, connecting four valves to one fieldbus address. Thus
the number of connectable valves can be increased in steps of four. The Valve Coupler actuates the integrated
solenoid valves, which in turn open or close the pneumatic control valves. 3/2-way and 5/2-way solenoid
valves can be combined as desired.
For larger installations the FieldConnex FieldBarrier can be incorporated into the interface housing,
thus allowing to control a multitude of pneumatic valves via just one fieldbus cable.

22
Function
The FieldConnex"! Fieldbus Cables are designed specifically for use in fieldbus installations according to IEC
61158-2. They feature two 0.8 mm (18 AWG) conductors with a drain wire and overall foil shield. They meet all
requirements of the Fieldbus Foundation Installation Guidelines as well as FISCO and FNICO. Cables, Cord Sets
and Extension cables can be used for indoor and outdoor installations. The sheathing materials are safe
against UV radiation and have low toxic emissions according to fire safety regulations. They are available in all
recommended colors for different applications and explosion protection methods.
Fieldbus bulk cables are available in higher wire gauges, too, to reduce attenuation in extended topologies.
They come on reels in standard lengths for efficient trunk installations as well as hard wiring of spurs on both
field device and fieldbus distribution modules such as Junction Box, Segment Protector or FieldBarrier. For
enhanced safety and harsh environments there are versions with additional armoring.
FieldConnex"! Cord sets will be used for the interconnection of a field device with a connector to a Junction
Box, Segment Protector or FieldBarrier with cable glands. Thus it is easy to quickly disconnect the field device
while the passive communication topology remains solidly terminated. The connector can be either male or
female, all recommended sheathing colors are available.
FieldConnex"! Extension Cables allow a quick and easy installation of the fieldbus topology by reducing the
need for cable terminations. They feature pre-configured male and female connectors, thus guaranteeing fault-
less connections by omitting the danger of wrong wire terminations. Extension Cables are the best choice for
modifications or elongations of existing networks.

Fieldbus Terminator for Function
field installation in To ensure a clear, safe digital fieldbus communication any signal
sturdy screw-in housing reflections in the fielbus lines have to be avoided. Therefore each fieldbus
segment requires specific terminating impedances at the opposing ends.
With the FieldConnex"! System the appropriate fieldbus terminators are
integrated in the power supply modules. At the field side the termination
can be switched on at most of the FieldConnex"! modules. In cases where
external terminators are required FieldConnex"! offers a variety of termina-
tors either for cabinet installation on DIN rail or in sturdy housings for
installation in hazardous environments. The latter are available for
different explosion protection methods and with various threads for
installation at the field device.
