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 FOUNDATION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 by

field devices, configuration and supervision software, communication interfaces, power supply 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 supervision

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, FOUNDATIONfieldbus allows the access to many variables, not only

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 communication 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 FOUNDATIONfieldbus devices.

Whenever possible, consult standards, physical regulations, 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 each 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 safety standards applicable to

the local classified areas regulating the installation and operation of the devices. These standards

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 each equipment is installed

accordingly.

Inadequate installation or use of a device on non-recommended applications can harm the system

performance and consequently the process, besides being a source of danger and accidents. Due

to this, it is recommended using only trained and qualified professionals for installation, operation

and maintenance.

NOTE

Damages caused to the devices by inadequate installations or use in the wrong applications are

not covered by warranty.

INSTALLATION

Network Wiring

Access the wiring block by removing the Electrical Connection Cover. This cover can be locked

closed by the cover locking screw; to release the cover, rotate the locking screw clockwise. (See

Figure 1.1).

Figure 1.1 - Housing Adjusting Screw and Cover Lock

NOTE

The covers should be closed by hand completely, until the O’Ring is tight. For more safety, do not

use tools in this operation.

Cable access to wiring connections is obtained by two outlets. Conduit threads should be sealed by

means of code-approved sealing methods. The unused outlet connection should be plugged

accordingly.

The wiring block has screws on which fork or ring-type terminals can be fastened. See Figure 1.2.

Figure 1.2 - Wiring Block

NOTE

Due to each device particularity, check the electric connection block in the specific equipment

manual. The LD302 was used above as example.

For convenience there are two ground terminals: one inside the cover and one external, located

close to the conduit entries. More details are described in Shield and Grounding item.

Avoid routing signal wiring close to power cables or switching equipment.

Figure 1.3 – Connecting a device to the Fieldbus network

Foundation Fieldbus Physical Medium, Cabling and Installation

The standard first versions specify two options for the physical layer: H1 and H2. The H1, with rate

of 31.25 Kbits/s is oriented basically to field device (transmitters, valve positioners, etc), and it can

be used in areas requiring intrinsic safety (explosive atmospheres). The H2, with rate from 1 to 2.5

Mbps, would be used to integrate controllers and more complex devices.

Due to the fast technological evolution, the H2 was substituted by the HSE that uses Ethernet at 100

Mbps. Therefore, for field devices connection there is the FOUNDATION fieldbus H1, with physical

layer based on ISAS50.02-1992 or IEC61158-2:2000. For connection among PLCs, Linking

Devices, Gateways and PCs, there is the FOUNDATION fieldbus HSE, based on Ethernet

(IEEE802.3-2000, ISO/IEC8802.3-2000).

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 powered by the

bus. In practice, there may be up to 12 field devices powered by the bus and other 20 devices not

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.

Figure 1.4 –Simplicity of the Foundation Fieldbus H1 Physical Layer (IEC61158-2)

Installation

1.3

The physical medium is a shielded twisted pair cable. The power supply and the communication are

done by the same pair, needing at least 9 V in the terminal of the device to energize it. It is

recommended that this tension be larger than 10 V, enough to keep a complete communication

signal (0.75 Vpp to 1 Vpp), taking into account the cable tension loss, the bus total consumption,

etc.

A modified Manchester code is used, producing a signal with null average value, that is, without DC

components. That code brings other advantages: frame formation (special characters for start

delimiter and end delimiter), formations of different physical topologies (bus and stars) and the

warranty that the data and the clock arrive at the same time (synchronous serial signal).

The signal modulation is done by the variation of a current of 10 mA to 31.25 Kbit/s in an equivalent

load of 50 Ω, resulting in a modulated voltage of 0.75 Vpp to 1 Vpp overlapping the bus voltage (9 –

32 Vdc).

Both the current and the operation minimum voltage can vary according to the manufacturer or

device model (consult the respective manual). For Smar devices, each fieldbus device consumes

about 12 mA.

Foundation Fieldbus HSE Network

This network is based on the same Ethernet physical layer. Several manufacturers offer specific

equipments for industrial applications, be it with adequate temperature range (-40 to 85 ºC), be with

specific functions for real time data communication.

The communication and synchronism characteristics among the devices are basically the same as

the H1, and the main differences are in determinism. Through the use of the Ethernet network in the

Foundation Fieldbus HSE network it is possible to build an industrial control network with shelf

components, independently of the manufacturer.

The HSE standard uses 100 Mbps, but nothing opposes the devices from communicating at higher

rates, like 1 Gbps or even the new 10 Gbps standard.

General Notions of Installation for the H1 Network

The H1 network represents a great digital communication solution for the factory ground, both in

safe as classified areas. It accepts topologies in bus, ring, star or tree, and even distances up to

1900 m without repeater.

Using up to 4 repeaters it is possible to cover a radius of approximately 10 km. The maximum

amount of devices in each H1 segment depends on the type of application, the length of the cables

and even the performance wanted for the network.

Figure 1.6 - Comparison of Wiring and Distribution of Control over the Network Devices

Main elements of the Foundation Fieldbus H1 Network

Cabling

The IEC61158-2 determines that the physical medium of the Foundation Fieldbus H1 network

should be a twisted pair cable. The properties of a field bus are determined by the electric conditions

of the cable used.

Although the IEC61158-2 doesn't specify the cable technically, the type A cable is highly

recommended, in order to guarantee the best communication conditions and distances involved.
