Tour to successful application of PROFIBUS PA

Experience from practiceIntroduction

Decision criteria for PROFIBUS

Planing: Key to success

Installation: Keeping it simple

Operation and plant up-keep: Realizing more benefits

Based on a bio diesel production plant

IntroductionPROFIBUS allows to make best use of all plant assets.

Planning makes PROFIBUS perfect in practice.

The plant at Biodiesel Schwedt

Second of its kind

Use of open technology FDT/DTM

Consequent use of PROFIBUS

Focus on life cycle cost

Decision criteriaPROFIBUS allows to make best use of all plant assets

Reasons for selecting PROFIBUS PA

Information quality with highest resolution

Only one A/D converter

Multiple variables on one line

Calibration only in the field device

Planing the infrastructureKey to success

PROFIBUS PA based on: IEC 61158-2

Power and digital data transmitted via one pair of wires

IEC 61158-2 defines physical layer only

Free choice of topology

Attribute ValueMax number of devices (Masters and instruments) 32Transmission Rate 31.25 kBit/sMin. current consumption per node 10 mAData transmission via current change +/- 9 mAMin. supply voltage 9 VOverall cable length max 1900 mSpur cable length max 120 m

Communication Master – Slave, Master – Master

Trunk-and-Spur Topology

Easy to install, manage and maintain

One device per spur

Optional short-circuit protection for the trunk

Just a spreadsheet for documentation

Zone 1/Class I, Div 2

Explosion Protection: IEC 60079-27, FISCO

FISCO: Fieldbus Intrinsically Safe Concept

Plug and play

Validation through simple documentation

Limitations in cable length or number of instruments

Zone 1/Class I, Div 2

High-Power Trunk Concept

FISCO at each field device

Increased safety for the trunk

Power for many devices

Easy installation, upkeep and maintenance

Trunk: Ex e

One device per output FISCO or Entity: Ex ia IIC

High-Power Trunk Concept

FISCO at each field device

Long cable runs for the trunk

Power for many devices

Easy installation, upkeep and maintenance

Zone 1/Class I, Div 2 Zone 0/Div. 1

Trunk: Ex e or FieldBarriers

One device per output FISCO or Entity: Ex ia IIC

Simple planning tools

Validate the installation

Ensure success early on

Automate tedious calculations

Preparing for installation and commissioning

Preconfiguration of field instruments in the officeSet device address, tagging

Set basic or known configuration

Store basic configuration in engineering station

InstallationSimplifying work in the field

PROFIBUS Simplifies Installation

Install device

Wire up the leads, cut back and install shielding

Connect leads to FieldBarrier

Common connections for all devices

Loop diagrams and marshalling are obsolete

Simple re-routing of wiring – without re-configuration

Automated checking procedures for the installation

Calibration applies to device only (not the installation)

Prior to loop check

Operation and plant up-keepRealizing more benefits

Operation and plant upkeep

Devices report status and diagnostics

The fieldbus installation reports diagnostics

FieldCare provides detailed diagnostic information

Interoperable – all devices in one engineering tool

Prognostic Maintenance

Detection of corrosion, abrasion or coating on the device

A reduced vibration frequency indicates coating, an increades frequency indicates corrosion or abrasion

Summary: PROFIBUS is enabling technology

Planning and EngineeringStandardised, well structioned

Good support by external tool (e.g. segment checker)

No additional work

CommissioningComfortable configuration

Complete documentation of all parameters

Detailed diagnosis

OperationReliable

Quick diagnosis in case of fault

Possibility of prognostic maintainance

Good luck with your plant with PROFIBUS!
