Introduction

This manual introduces the series 302 of Fieldbus Foundation devices.

They are: LD302 – FOUNDATIONFieldbus Pressure Transmitter, TT302 – FOUNDATION

Fieldbus Temperature Transmitter, IF302 – FOUNDATIONFieldbus Triple Channel Current

to Fieldbus Converter, FI302 – FOUNDATIONFieldbus Triple Channel Fieldbus to Current

Converter, FP302 - FOUNDATIONFieldbus to Pressure Converter and FY302 -

FOUNDATIONFieldbus Positioner.

They are based on a field-proven technology that provides reliable operation and high

performance. The digital technology used in the Series 302 enables the choice of several

types of function blocks. An easy interface between the field and the control room and several

interesting features that considerably reduce the installation, operation and maintenance costs

and will develop new ways to improve plant performance, plant safety and plant availability.

Fieldbus is not only a replacement for 4-20 mA or intelligent device protocols, it contains much

more. Fieldbus is a complete network system enabling migration and distribution of the control

functions to field devices, and vastly expands the amount of process and non-process

information flowing both from and to field devices.

Some of the advantages of bi-directional digital communications are known from existing

smart field devices protocols: Higher accuracy, multi-variable access, remote configuration

and diagnostics, and multi-dropping of several devices on a single pair of wires. Those

protocols were not intended to transfer control data, but maintain information. Therefore, they

were slow, being not efficient enough to be used to digital control by communication and not

giving opportunity to come to control strategies totally reside in the field.

Fieldbus overcame these limitations. Closed loop control with performance like a 4-20 mA

system requires higher speed. Since higher speed requires higher power consumption, this

clashes with the need for intrinsic safety. Therefore a moderately high communication speed

was selected, and the system was designed to have minimum communication over-head.

Using scheduling, the system controls the variables poling, algorithm execution and the traffic

to optimize the network usage, thus achieving high and secure closed loop performance.

Using FoundationFieldbus technology, with its capability to interconnect several devices,

very large control schemes can be constructed. In order to be user friendly, the function blocks

concept was introduced1, it means, basic automation functions performed by an application.

Each function block processes input parameters according to a specified algorithm and an

internal set of contained parameters. They produce output parameters that are available for

use within the same device or by other one in the application process. Using them, the user

may easily build and overview complex control strategies. Another advantage can be seen as

extending flexibility, considering that the control strategy may be edited without having to re-

wire or change any hardware.

Each field device has a set of blocks likes Analog Input, PID, Control Selector, etc., eliminating

the need for a separate control devices. The communication requirement is considerably

reduced, and that means less dead-time and tighter control is achieved, not to mention the

reduction in cost. Other function blocks are also available2. They allow flexibility in control

strategy implementation and guarantee interoperability together of Device Description.

The need for implementation of fieldbus in small as well as large systems was considered

when developing the Series 302 of fieldbus devices. They have a common feature of being

able to act as a master on the network and be configured locally using a magnetic tool,

eliminating the need for a configurator or console in very basic applications.

WARNING

This Manual is compatible with version 3.XX, where 3 denote

software version and XX software release. The indication 3.XX

means that this manual is compatible with any release of Series

302 field devices with software version 3.

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 - Housing Rotation).

Figure 1.1 - Housing Rotation

Cable access to wiring connections is obtained by one of the 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 - Wiring Block).

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

located close to the conduit entries.

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

WARNING

HAZARDOUS AREAS

In hazardous zones with explosion proof requirements, the

covers must be tightened with at least 7 turns. In order to avoid

moisture or corrosive gases, hand tighten the covers until the O-

rings are compressed. Lock the covers closed with the locking

screw.

In hazardous zones with intrinsically safe or non-incendive

requirements, the circuit entity parameters and applicable

installation procedures must be observed.

Cable access to wiring connections is obtained by one of the two

conduit outlets. Conduit threads should be sealed by means of

code-approved sealing methods. The unused outlet connection

should be plugged accordingly.

Should other certifications be necessary, refer to the certification

or specific standard for installation limitations.

The Series 302 devices are protected against reverse polarity, and can withstand up to 35

VDC without damage.

Physical Signaling

The Foundation



Fieldbus Series 302 devices use the 31.25 kbit/s voltage mode wire

media option for the physical signaling. All devices on the same bus must use the same

signaling. All devices are connected in parallel along the same pair of wires.

Various types of fieldbus devices may be connected on the same bus. The Series 302 device

is powered via bus. The limit for such devices is 16 for one bus for non-intrinsically safe

requirements.

In hazardous areas, the number of devices may be limited to 4 devices per safety barrier by

intrinsically safe restrictions.

One fieldbus network may have many barriers.

Bus-Powered

(Field device takes power from the bus)

Non Bus-Powered

(Field devices gets power over separate wires)

Figure 1.3 - Wire Media

A Smar fieldbus System consists of several fieldbus networks. A fieldbus network may consist

of several segments. Several fieldbus devices may be connected to each segment

Topologies

Almost any topology is possible. It is mainly a matter of where the terminator is connected.

•Bus

•Tree (Chicken-foot)

•Daisy-chain

•Point-to-point

As far as fieldbus is concerned that are all alike, what matters is the placement of the

terminator.

Of course combinations of two or more topologies is possible.

NOTE

Ring topology is not possible. Because connecting the bus in a

ring damage the Termination scheme.

Bus Topology

Devices are distributed along the trunk connected through spurs. A spur may be up to 120 m

long.

Figure 1.5 - Bus Topology

Tree topology

A main trunk runs from the control room into the field where it branches out to the individual

devices.

For tree topology it is important to ensure that the spur length does not exceeds the maximum

allowed.
