1 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 an idea of what PDM is and how to use it to communicate to a LR200 Radar unit via HART communications.

2 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

3 SIMATIC PDM A new, standardized approach
Now Before PDM SIMATIC PDM for operation of all field devices and components based on EDD technology Different programs for operation of the associated field devices and components One piece of software for standardized operation of all field devices Device Descriptions (DD)

4 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.)

5 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

6 HART - Device Description
PDM is a DD interpreter DD = Device Description Hand held Communicator 275 SIMATIC PDM HART - Device Description + HART - device

7 SIMATIC PDM Versatile communication
Communication with PROFIBUS field devices on PROFIBUS-DP on PROFIBUS-PA via PA coupler or via PA link HART field devices via SIMATIC ET200M remote I/O via SIMATIC ET200iS remote I/O via HART modem via HART multiplexer Company-specific field devices on SIPART bus via isolated coupling to SIREC recorders

8 Communication PROFIBUS

9 Communication HART on PROFIBUS

10 Communication HART via multiplexer

11 Communication HART via HART modem

12 Communication over Ethernet

13 SIMATIC PDM - Connection points in the automation system
Engineering Station ES Operator Station OS (e.g. Win CC) Ethernet .... .... .... S7- 400H S7- 400 S7- 300 IE/PB Link PROFIBUS DP kBit/s PROFIBUS PA PROFIBUS DP redundant PROFIBUS DP HART multiplexer / interface DP/PA link ET 200M ET 200iS PROFIBUS PA RS232/ RS485 Any device with any communication on the workbench Possible SIMATIC PDM connection point

14 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 ( 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 bits/sec (i.e. 2-3 updates/sec)

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

16 HART on PROFIBUS - COSTS
PROFIBUS PA wire is 2.45 Euro/meter HART wire is 1.42 Euro/meter

17 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

18 HART Commands HART commands are divided up into three types:
Universal commands Common practice commands Device specific commands You can connect to a HART device by: Using a ‘Generic’ DD that will give you just the Universal commands and Common practice commands but not the Device specific commands Using a DD that has been written for the device that will give you access to all the commands

19 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 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!

20 HART Communicator 275 (Emerson)
Does not have all the HART Library in it (Library is too big) HART Communicator 275 costs approx Euro PDM cost approx. 400 Euro for base unit

21 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 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

22 SIMATIC PDM Variants Stand alone Integrated into SIMATIC
Local installation Local connection to the field bus, service bus or electric circuit Local database with export option in XML Integrated into SIMATIC Integrated in hardware project System-wide commu-nication (routing) Optimum integration into SIMATIC S7 /PCS 7

23 SIMATIC PDM User interface (1)
SIMATIC PDM has Standardized displays and user interface Terminology and linguistics based on DIN V and IEC 65/349/CD, and conforms to VDI/VDA GMA 2187 is Windows-compatible Views of process devices Process devices – Network view Process devices – System view with status information Hardware project (integrated into SIMATIC S7 /PCS 7)

24 SIMATIC PDM User interface (2)
Documentation Online help and Getting Started Status of parameter values loaded, modified, invalid, initial value, not supported Automatic assignment: Device – Parameter data records User interface in German English French Spanish Italian Offline parameterization possible including consistency check

25 SIMATIC PDM User interface (3)
Parameterization / comparison Online with offline Device with device Presentation of process values Curves Bar chart Device diagnostics Status Quality Commissioning aids Calibration Alignment Adjustment Identification Bus scan (life list) Device identification HART multiplexer scan

26 Ordering Information - PDM

27 HART Modems RS-232 to HART Modem (7MF49971DA) - made by MACTek
USB to HART Modem (ordered from MACTek) MACTek can be found at

28 Example LR200 HART connection
PC HART Modem + - RB PLC HART Device If the PLC internal resistance is < 250 ohms, then RB of 250 to 350 ohms needs to be added.
