Introduction

INTRODUCTION

FOUNDATION fieldbus (FF) is an open architecture to integrate information, whose main objective is
to interconnect control devices and industrial automation, distributing the control functions for the
network and supplying information to all the layers of the system.

The F

OUNDATION fieldbus technology substitutes with advantages the 4-20mA + HART traditional,

technology making possible the bi-directional communication among the devices in a more efficient
way.

This technology is much more than a protocol of digital communication or a local network to field
instruments. It includes several technologies, such as distributed processing, advanced diagnosis
and redundancy. A FOUNDATION fieldbus system is heterogeneous and distributed, composed b y
field devices, configuration and supervision software, communication interfaces, po wer suppl y and
by its own physical network that interconnects them.

One of the functions of the field devices is to execute the user application of control and superv ision
distributed by the network. This is the big difference between FOUNDATION fieldbus and other
technologies that depend on a central controller to execute the algorithms.

Compared to other systems, F
related to the process, but also diagnostics of sensor and actuator, electronic components,
performance degradation, among others. Besides, there are other outstanding characteristics:

 Intrinsic safety for use in hazardous areas, with power supply and communicati on on the same

wire pair;

 Topology in bus or tree, with support to multiple masters in the communication bus;
 Deterministic (foreseeable) behavior, even with redundancy in several levels;
 Distribution of the control functions among the devices (distributed control);
 Standardized interfaces among the devices that facilitate interoperability;
 Application modeling using functional blocks language.

This manual presents details of fieldbus installation, besides common configuration points of Smar.
series 302 F

Whenever possible, consult standards, physical r egulations, as well as the safety practices of each
area.

Act with safety in the measurements, avoiding contact with terminals and wiring, because high
voltage can be present and cause electric discharge. Remember that ea ch plant and system has
their own safety details. To find out about them before beginning the work is very important.

To minimize the risk of potential problems related to safety, follow the safet y standards applica ble to
the local classified areas regulating the installation and operation of the devices. These standar ds
vary area by area and are constantly updated. It is the user's responsibility to determine which
standards should be followed in your applications and to guarantee that e ach equipment is installe d
accordingly.

Inadequate installation or use of a device o n non-recommended applications can harm t he system
performance and consequently the process, besides being a source of d anger and accidents. Due
to this, it is recommended using only trained and qualified professional s for installation, operation
and maintenance.

Damages caused to the devices by inadequate installations or use in the wrong applications are
not covered by warranty.

Foundation Fieldbus H1 Network

A Fieldbus network is composed by several H1 buses, connected to each other by bridges or
Foundation Fieldbus Linking Devices that connect the H1 networks to the HSE backbone.

According to definitions, each H1bus can hold, theoretically, up to 32 devices not pow
bus. In practice, there may be up to 12 field devices powered by the bus and other 20 devices not
powered by the bus, each one with a single logical address in the network (1 Byte). This limit is due
mainly to the electric characteristics of the power supply and the current consumption of the devices.
In practical terms, it is recommended that the total number of devices doesn't surpass 10, because
the network traffic tends to become very high and there may be performance degradation. In
classified areas, it is recommended to analyze the output of the intrinsic safety barrier to define the
number of devices. With the FISCO concept, there may be a larger amount of devices per segment.

The wiring length can reach 1900 m, and up to 4 repeaters can be used.

and if the cable supports it. The type A cable resistance of 22 O/Km is valid at 25 ºC. For example,
the resistance of the type A cable to 50 ºC is 24.58 Ω/Km. That should be taken into account in hot

Installation

H1 Network Terminators

Two bus terminators should be connected to the H1 network, being one in the PSI output and the
other in the last device (usually the most distant from the PSI), depending on the adopted topology.

If in the cabling distribution there is a junction box in the end of the main trunk w

ith several spurs, the

field terminator should be placed in this point, to facilitate the maintenance when removing devices.
Check the correct connection of the terminator, reminding

that the lack of terminators allows
communication intermittency, once there is no impedance match and there is reflection signal
increase.

The lack of a terminator or its connection in the incorrect point al

so degrades the signal, once it will
also be part of the cabling as an antenna. Its lack can increase the signal in more than 70% and an
additional terminator can increase the sign up to 30%. The attenuation and intermittency can
generate communication failure.

The H1 network terminator is formed by a resistor of 100 ± 2% and a capacitor

of 1 µF ± 20% in

series.

Power Supply

The power supply usually has an output of 24 Vdc with capacity of a few ampéres. The power supply
can operate in redundant mode and it should failure indication and protection against surges,
transients and short circuits. Smar makes the DF52 power supply that meets these characteristics.

In terms of power supply signal, consider as acceptable values in practice:

• Ripple

(mV):
< 25: excelent;
25 < r< 50: ok;
50 < r < 100: acceptable;
> 100: unacceptable.

In terms of communication signal, consider as acceptable values in practice:

•

750 to 1000 mVpp: ok;

> 1000 mVpp: Very high. A terminator may be lacking.
Some barriers and segment protectors, like spur guards, have high impedance in series and can
produce signals up to 2000 mV and even allow

the appropriate operation.

• < 250 mVpp: Very low. It is necessary to verify if there is more than 2 active terminators, power
supply, etc.

Some devices have polarity, others not, so it is very important to

assure the correct polarity of the
devices. All the devices are connected in parallel, that is, all the negative terminals together and all
the positive terminals together. The use of colored wires codified is recommended to distinguish the
positive from the negative.

Active Impedance

The active impedance avoids that the pow

er supply low impedance lessens the communication

signal of the bus, allowing the feeding to be supplied in the same wire pair.

Series 302 FIELDBUS FOUNDATION – Installation, Operation and Maintenance Manual

It works as low impedance for DC and high impedance for AC communication signal and may have
an additional internal terminator activated by

a frontal key. The active impedance is fundamental for

the network correct operation.
The Foundation Fieldbus impedance is on a device of non-isolated,

area;
b) The other devices in the classified area are passive;

Series 302 FIELDBUS FOUNDATION – Installation, Operation and Maintenance Manual

The FISCO concept was optimized so that a larger number of field devices is allowed according to
the bus length, taking into account the cable variation characteristics (R', L',C ') and terminators that
assist categories and groups of gases with a simple evaluation of the installation involving intrinsic
safety. Thus, it increased the current capacity per segment and facilitated the evaluation for the
user. Besides, when acquiring certified products, the user doesn't need to worry with calculations,
even in substitution of an operation.

The FISCO model represents a fast and easy way to project, install and operate H1 netw
installations on classified areas. The main idea is to supply more current to the H1 segment,
enabling among other advantages the connection of a greater number of equipments, when
compared to a conventional intrinsically safe installation. In summary, just follow the requirements
below:

Use certified and approved devices for FISCO applications;

•

Check the parameters of each device (U

•

Observe the parameters of the used cables carefully (R, L, C). Use type A cable

•

To observe the correct use of the terminators;

The main advantages when using a FISCO installation are:

•

Plug&Play actions in hazardous areas;
The system certification is not mandatory, but is up to user discretion;

•

The expansion of the application is very simple;

•

It is possible to connect the maximum number of devices in the classified area;

•

The installation costs are reduced;

•

There is no need for parameter recalculation when changing the devices.

•

FNICO

A new concept that also appears on the scene is F

NICO (Fieldbus Nonincendive Concept), which is
similar to the FISCO, but limited for use in Zone 2. Both concepts, FISCO and FNICO, are turning
the fieldbus more attractive for use in hazardous areas.
FNICO is allowed in North America countries or those based on standards of this region. T
concept considers:

• Input capacitance/inductance;

Maximum cabling and spurs;

•
And the following:

•

Vmax of each field device > Voc of the Repeater;
Imax of each field device > Ioc of the Repeater;

•

Pmax of each field device > Poc of the Repeater.

•
Repeaters with 215 mA of capacity are common.

Transient Supressor

Whenever having an effective distance larger than 100 m on the
position between two grounded points, the use of transient protectors is recommended, on the
distance initial and final points. On the horizontal, its use is recommended between 50 and 100 m.

The transient protector should be installed immediately

after the PSI, before each device and also in

the junction box. In classified areas, the use of certified protectors is recommended. See Figure

According to the IEC61158-2, to ground means to be permanently
sufficiently low impedance and with enough conduction capacity to prevent any voltage to cause
damages to equipments or people.

Voltage lines with 0 V should be connected to the

ground and be galvanically isolated from the bus.

The purpose of grounding the shield is to avoid high frequency noises.
Preferably, the shield should be grounded in two points, in the beginning and the

long as there is no potential difference between these points, allowing the existence of loop current
and access to it. In practice, when this difference exists, the shield should be grounded in a single
point, in other words, at the power supply or the intrinsic safety barrier. The continuity of the cable
shield must be kept in more than 90% of the cable total length. See the Figure 1.17.

The shield should cover the electric circuits completely

through the connectors, couplers, splices

and distribution and junction boxes.
The shield should never be used as a signal driver. T

he shield continuity should be checked until the
last fieldbus device on the segment, and the connection and finishing inspected, because the shield
should not be grounded to the equipment housing.

In classified areas, if a potential equalization betw

een the safe area and the hazardous area would
not be possible, the shield should be connected directly to the ground (Equipotencial Bonding
System) only on the dangerous area side. In the safe area, the shield should be connected
preferably through a ceramic capacitive coupler, like a solid dielectric capacitor, C =10 nF, isolation
voltage ≥ 1.5 kV). See Figures 1.18 and 1.19.

1.14

Figure 1.18 – Ideal Combination of Shield and Grounding

Installation

Figure 1.19 – Capacitive Grounding

IEC61158-2 recommends the complete isolation. This method is

used mainly in the United States
and in England. In this case, the shield is isolated from all the grounds, except the negative ground
of the power supply or of the intrinsic safety barrier on the safe side. The shield has continuity from
the PSI output, through the junction and distribution boxes and reaches the equipments. The
equipment housings are grounded individually on the non-safety side. This method has the
disadvantage of not entirely protecting the signals from the high frequency signals and, depending
on the cable topology and length; in some cases it can generate communication intermittency. Metal
ducts are recommended in these cases.

Another complementary form would be to ground the junction boxes and the equipment housings in
an equipotencial ground line on the non-safety

side. The grounds on the non-safety side and on the

safe side are separate.
The multiple grounding conditions are also common, w

ith more effective protection from high
frequency and electromagnetic noises. This method is preferentially adopted in Germany and some
countries in Europe. In this method, the shield is grounded on the negative ground point of the
power supply or the intrinsic safety barrier on the safe side, in addition to the junction boxes ground
and in the equipment housings and these are also grounded on the non-safety side. Another
complementary condition would be the grounds being connected together in an equipontencial
ground line, uniting the non-safety side to the safe side.

For more details, always consult the local safety

standards. Use the IEC60079-14 as reference for

applications in classified areas. See some ground and shield ways on Figure 1.20.

Intrinsic Safety Definition

Intrinsic safety limits the equipment circuit energy, so that they

do not cause the ignition of
potentially explosive atmospheres even in the occurrence of failures that may produce sparks or
warm surfaces in contact.

As it deals with energy limitation,

this is an adequate technique for electronic equipments, typically

used in control and process instrumentation.

Foundation Fieldbus Technology and Intrinsic Safety

According to standards, 1 to 4 devices may be connected together in the hazardous areas, after the
Intrinsic Safety Barrier, and two more devices in the safe areas in the same bus.

With the energy limitations for each device in the hazardous area, some instruments w

ill need to be
run through other power supplies. Therefore, devices such as, process analyzers, of I/O
subsystems, magnetic or Coriolis effect meters can combine intrinsic safety with other installation or
contention techniques for protection against possible explosions.

There is a set of rules for applications in hazardous areas that uses intrinsic
fieldbus technology refers to the lengths of the segments, limits of currents in the power supply and
parameters as capacitance and inductance, as well as parameters of equipment failures. The
FISCO method provides an easy implementation for applications intrinsically safe in fieldbus, giving
flexibility, operational safety to the applications and reducing installation costs, since one can handle
up to 10 devices in an Ex network. Besides, the possibility of online handling simplifies
commissioning, startup and maintenance. More power means more devices and less cables, hence
less barriers.

Equipments compliant to FISCO can be directly connected to
model. The reverse condition needs to be evaluated.

Following are described some key points that should be considered during the implementation,
involving classified areas and fieldbus:

• Which is the hazardous area. Remember that non-incendive is only allowed in Division 2 areas

and intrinsic safety equipment only in Division Div 1 and Division Div 2 areas);

• Which size and scalability required ;

• Will there be short circuit protection for the main trunk and the spurs?

• Which are the acceptable safety level and risks? (Projects involving intrinsic safety take into

account the components failure and allow maintenance while being powered, although without heat.
Conversely, non-incendive equipment doesn't allow maintenance being performed during powering
or even heat exchange.

• Are there limitations to shutdowns?

• Do the engineering and the maintenance teams have proven experience with hazardous and

classified areas?

• Do all the devices have certification compatible with the application?

• Are the facilities compliant to the area and country safety standards?

For more details consult IEC60079-27, “Fieldbus Intrinsically Safe Concept (FISCO)” and “Fieldbus
Non-Incendive Concept (FNICO)”.

LCD Indicator

OPERATION

The Series 302 devices have an optional digital LCD display that works as a local operator interfac e
for basic factory pre-programmed functions or for personalized user functions through the host
system remote tool in the engineering and/or maintenance station. To accomplish these
configurations through local adjustment, use the SD-1 magnetic tool for local adjustment.

In a more complete and friendly way, all confi
accomplished remotely, by using, for example, a configurador, an engineering or maintenance
console. For more details consult the Syscon network manual configurator or the AssetView asset
manager.

The configuration is composed of the autom
the tag attribution and the selection or instantiation of function blocks that will be executed inside the
device. And based on these, build the control strategies that it is made by selecting the blocks, inter­connecting and adjusting the internal parameters in order to get the required operation.

The local and remote operation interfaces also ena ble monitoring the performance of the variables,
such

as process variables and setpoint. These variables de pend on their use and can be accessed

in a single communication.
The management of acyclic events is performed automatically. When alarms and other critical

events occur, the function block informs the user directly, without the need for the interface to
execute a scan periodically to determine if there is an alarm condition. It takes some time for th e
recognition to be received. This will happen even if the alert condition disappeare d and it will be
reported by the device. If it is not recognized in a given period, the event report will be issued.

Similarly, the communication informs automatically the configuration changes involving statistical
data. An event is generated by an internal mechanism when a change occurs, so the host won't
need to constantly check for a possible system overload.

Through the scheduled communication, the transfer of connection parameters between function

can be synchronized with the block execution. Thus, the block that uses an input parameter

blocks
can receive this data before running the algorithm block.

Due to the configuration and alarm mechanism, the so-called "non-operational traffic", has been
minimal, with more time for operational traffic and control improvement.

After being configured, the system saves the parameter tags and names to all ow for an optimized
communic

Using the device function blocks, the speed can increasingly be improved. For example, using the
PID block for control, there is one communication less , unlike the control done by another device.
This decreases the duration of the control application and therefore the network macro-cycle.

The LCD indicator displays each function block parameter that is user-selectable. Some of them can
be changed by local action, according to the user configuration and the parameter properties.

When the user chooses a variable, the display shows the parameter mnemonic, its value and status
when it is different from “good”. The field and status indicators are explained in Figure 2.1.

Operation

Communication

The friendly Man-Machine Interface (MMI) provides an efficient and productive interaction with the
user, without previous knowledge of the software. A large library of pre-configured and tested
templates for devices, control strategies and graphic symbols makes the engineering system as
efficient and as fast as it can be. Only a minimum of data needs to be entered when defining I/Os,
networking, and control strategies.

Support Tool

The plant control configuration is now managed by a unique tool, the Studio30 2, which integrates all
applications included in the Smar’s SYSTEM302 Enterprise Automation System and incorporates
Windows-based Users and Groups to provide a multi-user environment. Now the Syscon project
files have controlled access defined for each professional operating the p lant and a precise register
of the history of modifications to guarantee the integrity of the project configuration data.

Local Adjustment Methodology

Enter the local adjustment by inserting the magnetic tool in the ZERO hole. Wait until the
"MD" flag appears on the LCD. Then insert the magnetic tool t wice in the SPAN hole The

message "LOC ADJ" will appear. Next, insert the magnetic tool in the ZERO hole. L eaving
the tool in the ZERO hole, browse through the items in the menu. The ZERO hole is used for
browsing. By moving the tool to the SPAN hole, the parameter can be set on another value.

SUMMARY:
Zero (z) Browses
Span (s) Selects / Actions.

To browse the available parameter options, move the tool to the ZERO hole to go to the
specific menu option. See Figure 3.12. Then make a selection by moving the tool to SPAN
when the choice is displayed. If the options are on/off, or enumerated, the option will appear in
the value field. The mnemonic of each parameter will be displaye d on the alphanumeric field.
This is for viewing only, as changes are not to be m ade on the tag configured for the bl ock. If
the Functional Block tag is longer than five characters, it will move to the left.

working speed is reduced.

When the user inserts in and removes the magnetic tool fro m the SP
decrement will be done in steps.

Remove the tool when the desired value is reached.
When incrementing a variable beyond the value desire d, move the tool to ZERO and

the decrement option of the same variable appears. By moving the tool to SPAN, it is reduce d
to the desired value. For "undershoot", the opposite applies.

To exit from any menu, remove the tool from any hole fo r a break, and an escape sequence

Then the user enters the local adjustment, the last parameter used before is shown.

To monitor a parameter in normal operation, the user just needs to browse at the desired
parameter and remove the magnetic tool. Then this parameter will be sho wn continuously on
the LCD.

Every action should be done critically because no confirmation is required to change the
parameter value. After writing the value, it is automatically stored in the E2PROM memory.

How to Configure a Transducer Block

Each time you select a field device on the config
transducer block as it appears on screen.

The transducer block has an algorithm, a set of contained parameters and a channel

ecting it to a function block.

conn
The algorithm describes the behavior of the transd

I/O hardware and other function block. There are several parameters in the Function Block.
They can be divided into Standard and Manufacturer Specific.

The standard parameters are available for such class of inst ruments as pressure, temper ature
actuator devices, etc., whatever the manufacturer. Oppositely, the manufacturer specific ones
are defined only by their manufacturer. Common manufacturer specific parameters are
calibration settings, materials information, linearization curve, etc.

When you perform a standard routine as a calibr
method. The method is generally defined as guideline to help the user to make common tasks.

Calibration

This is a specific method to make the calibration operation. It is necessar

should be used to configure this process: CAL_POINT_HI, CAL_POINT_LO, CAL_MIN_SPAN

device, the minimum allowable span value for calibration (if necessary) and the engine ering

TROUBLESHOOTING

Device Connections

• Check wiring polarity and continuity;

• Check for shorts or ground loops;

• Check if the power supply connector is connected;

• Check if the shield is not used as a conductor. It should be grounded at only

one end;

• Check the coupler/link connections.

Power Supply

• Check power supply output. The voltage must be between 9 - 32 VDC at the Series 303
device terminals.

Network Connection

• Check that the topology is correct and all devices are connected in parallel;

• Check that two bus terminators are OK and correctly positioned;

• Check that the bus terminators are according to the specifications;

• Check length of trunk and spurs;

• Check the connections of the coupler are correct and correctly positioned;

• Check the baud r

• Check low isolation.

Network Configuration

• Make sure the Device Tag is configured if system configuration is desired;

• Make sure that device address, master connection, and the address.

Electronic Circuit Failure

• Check the main board for defect by replacing it with a spare one.

COMMUNICATION ERRORS

Installation problems, non-configuration or other main causes of communication err ors:

•

Loose connections

• Badly i nstalled terminator, without endpoint.

• Very low or unstable power supply;

•

Very long spurs or excessive spurs;

• Wrong gro unding or no grounding;

•

Water leak due to poor electric connections and cable clamp.

Factory Init

The Factory Init should be tried as a last optio
equipment presents some problem related to the function blocks or the communication. This

operation must only be carried out by authorized technical personnel and with the process
offline, since the equipment will b e configured with standard and factory data.

This procedure resets all the configurations run on the equ ipment, after which a partial download
should be performed. With exception to the equipment physical address and the GSD identifier
number selector parameter. After doing this, all configurations must b e remade according to their
application.

Two magnetic tools should be used to this effect, on the equipment, withdra w the nut that fixes the
identification tag on the top of the housing, so that access is gained to the "S" and "Z" holes.

The operations to follow are:

1) Switch off the equipme nt, insert the magnetic tools and keep them in the holes (the magnetic
end in the holes);

2)

Power up the equipment;

3) As soon as Factor y Init is shown on t he displa y, take off the tools and wait for the "5" s ymbol on
the right upper corner of the display to unlit, thus indicating the end of the operation.

This procedure makes effective the entire factory configuration and will eliminate ev entual problems
with the function blocks or with the equipment communication.

Note that this procedure must be performed by authorized personal only and with the process
switched off, since the equipment will be configured with standard and factory data.
