1.0 PROFIBUS PA™Overview

1.1 Des ription

PROFIBUS PA™is a digital communications system that

serially interconnects devices in the field. A fieldbus system

is similar to a Distributed Control System (DCS) with two

exceptions:

• PROFIBUS PA™is a system that allows the user to

distribute control across a network. Fieldbus devices are

smart and actually maintain control over the system.

Unlike 4–20 mA analog installations in which the two wires

carry a single variable (the varying 4–20 mA current), a dig-

ital communications scheme such as PROFIBUS PA™con-

siders the two wires as a network. The network can carry

many process variables as well as other information. The

Model 706PA transmitter is a PROFIBUS PA™certified

device that communicates with the DPV1 protocol operat-

ing at 31.25 kbits/sec. The MBP physical layer is an

approved IEC 61158 standard.

An IEC61158 shielded twisted pair wire segment can be as

long as 6234 feet (1900 meters) without a repeater. Up to

4 repeaters per segment can be used to extend the distance.

The maximum number of devices allowed on a fieldbus seg-

ment is 32 although this depends on the current draw

of the devices on any given segment.

Details regarding cable specifications, grounding, termination,

and other network information can be found in IEC 61158

or the technical guideline “PROFIBUS PA™User and

Installation uideline” at www.profibus.com.

1.2 Benefits

The benefits of PROFIBUS PA™can be found throughout

all phases of an installation:

1. Design/Installation: Connecting multiple devices to a single

pair of wires means less wire and fewer I/O equipment.

Initial Engineering costs are also reduced because

PROFIBUS International requires interoperability, defined

as “the ability to operate multiple devices in the same system,

regardless of manufacturer, without a loss of functionality.”

All PROFIBUS PA™devices must be tested for

interoperability by a PI accredited, independent testing

agency. Magnetrol Model 706PA device certification infor-

mation can be found at www.profibus.com.

2. Operation: A PROFIBUS PA™system allows for multiple

variables to be brought back from each device to the control

room for additional trending and reporting.

3. Maintenance: The self-diagnostics residing in the smart

field devices minimizes the need to send maintenance

personnel to the field.

1.3 Devi e Configuration

The function of a PROFIBUS PA™device is determined by

the arrangement of a system of blocks. The types of blocks

used in a typical User Application are described as follows:

Physical Block describes the characteristics of the

PROFIBUS PA™device such as the device name,

manufacturer, and serial number.

Function Blocks are built into the PROFIBUS PA™devices

as needed to provide the desired control system behavior.

There can be numerous function blocks in a single User

Application.

Transducer Blocks contain information such as calibration

parameters and sensor type. They are used to connect the

sensor to the input function blocks.

An important requirement of fieldbus devices is the interop-

erability concept mentioned earlier. Device Description

(DD) technology can provide extended descriptions for

each object and provides pertinent information useful for a

host system.

DDs are similar to the drivers that your personal computer

(PC) uses to operate peripheral devices connected to it.

General PROFIBUS Information:

• The Model 706 supports PA Profile Version 3.02

• The Ident Number issued by the PNO for Magnetrol

Model 706 is 0x101A. The Ident Number is included in

the name of the SD file.

• The eneral Station Description ( SD) file provides

information on the features and performance capabilities

of a PROFIBUS device to allow easy configuration of

PROFIBUS networks with devices from different manu-

facturers. The manufacturer-specific SD file for the

Model 706PA is MI01101A.gsd. Also, a bitmap file speci-

fied in the SD file provides a symbolic representation of

the device for network configuration tools.

• The Model 706PA can also use the profile-specific SD

file PA139707.gsd. If this general SD file is used, the

“Ident number Selector” parameter in the Physical Block

must be set to the profile-specific ident number. The

default selection of the “Ident Number Selector” parameter

is the manufacturer-specific ident number.

• A Device Description is available for configuring the

device using Simatic PDM.

• The range of device bus addresses is 0 to 126. 126 is the

default address and all units will ship with address 126

unless a non-default address assignment is requested by the

customer. The address can be changed via the fieldbus or

the local LCD interface.

1.4 Intrinsi Safety

The IEC 61158 physical layer supports Intrinsic Safety (IS)

applications with bus-powered devices. To accomplish this,

an IS barrier or galvanic isolator is placed between the

power supply in the safe area and the device in the

hazardous area.

IEC 61158 also supports the Fieldbus Intrinsically Safe

Concept (FISCO) model which allows more field devices in

a network. The FISCO model considers the capacitance and

inductance of the wiring to be distributed along its entire

length. Therefore, the stored energy during a fault will be

less and more devices are permitted on a pair of wires.

Instead of the conservative entity model, which only allows

about 90 mA of current, the FISCO model allows a maxi-

mum of 110 mA for Class II C installations and 240 mA

for Class II B installations.

FISCO certifying agencies have limited the maximum

segment length to 1000 meters because the FISCO model

does not rely on standardized ignition curves.

The Model 706 PA is available with entity IS, FISCO IS,

FNICO non-incendive, or explosion proof approvals.

2.0 Fun tion Blo ks

2.1 Overview

The Eclipse Model 706 uided Wave Radar Level

Transmitter operates on the principle of Time Domain

Reflectometry (TDR).

The Eclipse Model 706PA is a uided Wave Radar ( WR)

level transmitter with twelve PROFIBUS PA™Blocks (one

Physical Block, three Transducer Blocks, and eight Analog

Input blocks). The idea of Function Blocks, which a user

can customize for a particular application, is a key concept

of fieldbus topology. Function Blocks consist of an algo-

rithm, inputs and outputs, and a user-defined name.

The TRANSDUCER block output is available to the

network through the ANALO INPUT blocks.

The ANALO INPUT blocks (AI) take the TRANSDUCER

block measured values and makes them available as an

analog value to the network. The AI blocks have scaling

conversion, filtering, and alarm functions.

2.1.1 Standard PROFIBUS Block Parameters

The following are general descriptions of the parameters

common to all blocks. Additional information for a given

parameter is described later in that specific block section.

BLOCK_OBJECT: Contains the characteristics of the

block. This object applies to every block and is placed

before the first parameter.

parameters in the associated block. ST_REV will be incre-

mented each time a static parameter is changed.

TAG_DESC (tag descriptor): A user-supplied description

of the block.

The actual mode is set by the block during its execution to

reflect the mode used during execution

The permitted mode shows which changes of the target

mode are valid for the specific block

ALARM_SUM: This parameter summarized the status of

up to 16 block alarms.

2.2 Physi al Blo k

The Physical Block contains data specific to the Model

706PA transmitter, along with some information about the

firmware.

NOTE: The Physical Block has no control function.
