Before PDM
Different programs
for operation of the associated
field devices and components
Now
SIMATIC PDM
for
operation of all field devices
and components
based on EDD technology
One piece of

Automation and Drives
DD
Setting a New
Standard
of Integration
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.)

A word about HART Protocol
Setting a New
Standard

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
Setting a New

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 Integrated
Automation (TIA)
- PDM will work fine
- Main process variable is updated just as fast
as PROFIBUS PA
- HART can be Cheaper!

HART on PROFIBUS
Setting a New

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

Automation and Drives
HART Commands
Setting a New
Standard
of Integration
HART commands are divided up into three types:
Universal commands
Common practice commands
Device 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

Automation and Drives
PDM uses HCF Library
Setting a New
Standard
of Integration
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 have
had 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)
Setting a New
Standard
of Integration
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

Automation and Drives
AMS software (Emerson)
Setting a New
Standard
of Integration
Competes with PDM
Works with HART and Foundation Fieldbus
Has some nice features
However:
- AMS software not support straight use of the HCF
library
- 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
