Foundation™ Fieldbus Overview 5
Section 5: Foundation™ Fieldbus Overview
Section 5: Foundation™ Fieldbus Overview
Foundation Fieldbus is an open networking standard which provides an open specification for both the
control application and the communication on the bus.
Foundation Fieldbus communication protocol is an industry proven international standard
(IEC 61158-2) designed for use in the process industry and also complies with the ISA-SP50
recommendation for fieldbus devices.
The major benefits in adopting this standard includes:
• Multi-drop capability with up to 32 devices per segment;
• Extended trunk length using repeaters which increase the total bus length and the number
of devices in the network;
• Power and communications over the same shielded twisted pair network that allow to know
the physical status of ICON3000 actuator even if it is without actuator mains power;
• Distribution of the control into the field devices reducing the amount of control equipment
in the plant.
This last item is one of the more advantages of Foundation Fieldbus which uses standards ‘Function
Blocks’ and Device Descriptions to implement control strategy. Function Blocks are standardized
automation functions with defined behaviour used to represent different type of functions such
as discrete input (DI), discrete output (DO), analog input (AI), analog output (AO), Proportional /
Integral / Derivative (PID), etc.
Furthermore, every Foundation Fieldbus device has a Resource Block and at least a Transducer Block.
Once the hardware of a Foundation Fieldbus device is configured, fieldbus communication is used to
configure the transducer block parameters. The desired transducer functionality is associated with a
specific function block via a Channel.
The host system is used to link the function blocks together to create a control application that can
be downloaded to the devices in the segment.

Foundation™ Fieldbus Overview6
Section 5: Foundation™ Fieldbus Overview
5.1 FoundationtM Fieldbus Technology
Foundation Fieldbus technology consists of:
• Physical Layer
• Communication “Stack”
• User Application
The Open System Interconnect (OSI) layered communication model is used to model these
components as shows in the following Figure:
Figure 2
The Physical Layer and the Data Link Layer correspond respectively to OSI layer 1 and layer 2.
The Communication Stack is comprised of OSI layers 2 and 7; the fieldbus protocol does not use OSI
layers 3, 4, 5 and 6.
The User Application is not defined by the OSI model. Fieldbus Foundation has specified a User
Application model that Biffi has applied for FF2000v4 rev. 3 interface.
5.1.1 Physical Layer
FF2000v4 rev. 3 implements the Physical layer standards H1 that Foundation Fieldbus defines for
field device connections. The bus communication is fixed at 31.25 kbit/second, the devices can be
powered directly from the fieldbus and operate on wiring previously used for 4 - 20 mA devices.
FF2000v4 rev. 3 module is a bus powered interface: it will continue to communicate to the other
devices in the segment even if the actuator is powered off.
H1 fieldbus also supports intrinsically safe (I.S.) applications: in this case the appropriate barriers will
be used.
Biffi electrical actuators ICON3000 and are certified explosion proof and do not require an
intrinsically safe network. To preserve hazardous area protection armoured cables or conduits
will be used.

5.2 Fieldbus Topology and Wiring
General structures of H1 networks are shown in the following Figure:
Figure 5
An appropriate termination conditioning network (terminators) must be placed at the beginning
and at the end of each segment. A suitable power supply has to be added in the segments where bus
power devices are connected.
The following Table shows the types of cables indicated by IEC / ISA Physical Layer Standard.
Table 2.
Type Description Size Max Length
Type A Shielded, twisted pair 18 AWG 1,900 m
Type B Multi twisted pair with shield 22 AWG 1,200 m
The total length of the H1 fieldbus is determined by several factors as the cable type, I.S. option and
also the total spurs length has to be considered in the total fieldbus length.
Furthermore, it is also necessary to grant to each bus powered device the minimum requested
voltage to work properly since the cable length will cause a voltage drop over the line.
The FF2000v4 rev. 3 module is a bus powered device and it will work with the following
electrical parameters:
Voltage supply: minimum 9 V DC
maximum 32 V DC
Current drain: nominal 19 mA
maximum (fault) 24 mA

NOTICE
Each spur has been considered 3 m long.
As shown in the Figure, the current drawn by the actuators cause a voltage drop of 5.8 V on the
Section L1and a voltage drop of 0.9 V on the Section L2.
5.2.1 Cable Selection
The preferred cable is specified in the IEC / ISA Physical Layer Standard, Clause 22.7.2 for conformance
testing and it is referred to as “Type A” fieldbus cable.
Belden 3076F is a “Type A” fieldbus cable. The following Table shows the electrical characteristics:
Table 3.
Belden 3076F
Description 18 AWG (7x26) Tinned Copper conductor, Polyethylene
insulation, Aluminium Foil-Polyester Tape (Beldfoil) shield
Shielding 100% shield coverage
Size 18 AWG (0.78 mm2)
Nominal Resistance 24 Ω/km @ 25 °C
Nominal Mutual Capacitance 78.7 pF/m @ 1 KHz
Nominal Impedance 100 Ω @ 31.25 KHz
Temperature rating -40 to +105 °C
5.3 Terminators
Each segment must be properly connected to a termination conditioning network (terminators)
placed at the beginning and at the end of each segment.
The terminators prevent distortion and signal loss and are typically purchased and installed as a
pre-assembled sealed module.
The actuator is not equipped with termination facilities.
The following Figure shows an H1 segment where 6 actuators are connected in a tree structure;
the example highlight the voltage at each device:

Section 5: Foundation™ Fieldbus Overview
5.4 Shielding
When using shielded cable, connect each spur’s shield to the trunk shield and connect the overall
shield to ground at one point. Do not connect the spur’s shield in to the actuator ground.
Figure 7
5.5 Link Master Capabilities
FF2000v4 rev. 3 has Link Master (LM) capabilities; It contains Link Active Scheduler (LAS)
functionality, that can control communications on H1 fieldbus Link.
The LAS schedules and controls the segment communication. There must be at least one LM on an
H1 Link; one of those LM devices will be elected to serve as LAS. In a redundant system containing
multiple Link Masters, one of the Link Masters will become the LAS if the active LAS fails.
The LM functionality could be enabled or disabled by the configuration utility.

5.6 Field Diagnostic Profile
The FF2000v4 rev. 3 interface, implements FF-912 Field Diagnostic Profile specification. It is
implemented by a specific parameter group of Resource Block. The diagnostics are divided into four
categories: Failure, Out of specification, Maintenance and Check Function - consistent with NAMUR
NE-107. Each of these categories share 32 conditions. Each condition can be mapped or unmapped
for each category by selecting the appropriate bit in FD_*_MAP parameter. If a condition is mapped,
then it is indicated in the parameter FD_*_ACTIVE. If the condition in FD_*_ACTIVE parameter is
not masked the corresponding bit in parameter FD_*_MASK, then the condition will be queued for
transmission using the corresponding FD_*_ALM parameter associated with the priority indicated by
the parameter FD_*_PRI.
The four categories of conditions are defined below.
Table 4.
Maintenance Although the output signal is valid, the wear reserve is nearly exhausted or a function will
soon be restricted due to operational conditions e.g. build-up of deposits.
Off-Specification
Off-specification means that the device is operating outside its specified range or an internal
diagnostic indicates deviations from measured or set values due to internal problems in the
device or process characteristics (e.g. bubble formation in flow metering or valve sticking).
Check Function Output signal temporarily invalid (e.g. frozen) due to on-going work on the device.
Failed Output signal invalid due to malfunction in the field device or its peripherals.
With the FD_*_ACTIVE parameters you know the result after the filtering by FD_*_MAP. Prior to
filtering by FD_*_MAP, the detected conditions may be observed in the FD_Simulate.Diagnostic_Value.
The complete list and functionality of Field Diagnostic parameters implemented in FF2000v4 rev. 3
interface is reported on the Resource Block paragraph. All the parameter related to Field diagnostic
are prefixed with FD_.
In Table below are listed all the conditions handled by FF2000v4 rev. 3 with respectively manufacturer
default mapping and Recommended Action.
