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.

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 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)

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

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

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

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

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

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

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!

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 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
