Introduction to SIMATIC PDM And How to connect to a LR200 Radar via HART

Agenda:

- Overview of PDM - Example of how to connect to a LR200

The objective of this web seminar is to give the viewer anidea of what PDM is and how to use it to communicate to a LR200 Radar unit via HART communications.

What is PDM?

Stands for Process Device Manager

A configuration tool Used for:- Commissioning field devices- Maintenance of field devices- Diagnosing field devices- Display field devices

SIMATIC PDMA new, standardized approach

One piece of software for standardized operation of all field devices

Device Descriptions (DD)

Now Before PDM

Different programs for operation of the associated field devices and components

SIMATIC PDM for

operation of all field devices and components

based on EDD technology

PDM & LR200 Webinar




of Integration

DD

Proper name is EDD = Electronic Device Descriptor

Describes:

All the parameters in the device

All the interactions between parameters in the device

How to read/write those parameters over the communication bus

Describes simple methods for performing functions (ie set address, quick start etc.)

Electronic Device Descriptor Language EDDL

is a standard for Hart, PROFIBUS and Foundation Fieldbus (OPEN)

Stores information as a text file, therefore it is independent on PC operating system

A word about HART Protocol

Highway Addressable Remote Transducer Based on Bell 202 Frequency shift keying to superimpose

digital signal on top of a 4-20 mA signal Open standard (www.hartcomm.org)

Designed to: Replace 4-20 mA Remote configuration Remote diagnostics Can be multi-dropped (up to 15)

Analog and digital communications Analog is fast (continuous) Digital is slow - 1200 bits/sec (i.e. 2-3 updates/sec)

HART devices on PROFIBUS DP networks

Use a ET200M remote I/O rack

Advantages:- Have ‘best in class’- Over 90% of fieldbus devices sold are HART- This solution is part of Totally IntegratedAutomation (TIA)- PDM will work fine- Main process variable is updated just as fast as PROFIBUS PA- HART can be Cheaper!

HART on PROFIBUS

Installation costs can remove the Hardware savings

Some installations, HART is cheaper

Some installations, PROFIBUS PA is cheaper

Point to Remember: YOU CAN CONNECT ANY HART DEVICE TO PROFIBUS

PDM & LR200 Webinar




of Integration

HART Commands

HART commands are divided up into three types:Universal commandsCommon practice commandsDevice specific commands

You can connect to a HART device by:1. Using a ‘Generic’ DD that will give you just the

Universal commands and Common practice commands but not the Device specific commands

2. Using a DD that has been written for the device that will give you access to all the commands

PDM & LR200 Webinar




of Integration

PDM uses HCF Library

This means:- PDM can connect to any HART device using a ‘Generic’ DD

- PDM can connect to any HART device using the device specific DD in the HCF Library

- PDM can connect to many devices that havehad a special DD written for it for PDM

All Siemens-Milltronics equipment that has HART can connect to PDM in all three way!

HART Communicator 275 (Emerson)

Does not have all the HART Library in it (Library is too big)

HART Communicator 275 costs approx. 3000 Euro

PDM cost approx. 400 Euro for base unit

AMS software (Emerson)

Competes with PDM

Works with HART and Foundation Fieldbus

Has some nice features

However:- AMS software not support straight use of the HCFlibrary - AMS software can connect to any device but only with Universal commands and the common

practice commands.- This is not enough to configure devices!

Device has to be made ‘AMSaware’ to use all HART commands
