9.8 Process Device Manager (PDM)

The Process Device Manager (PDM) is a Siemens PC program designed to configure HART

®

and

PROFIBUS devices. Device Descriptions (DDs) are used to integrate different devices into the
PDM.

9.8.1 Installation

If the signal converter Device Description has not yet been installed on the PDM system, a so-
called Device Install HART

®

PDM is required for the signal converter. This is available for

download from the website or on CD-ROM.

For installation with the Device Install, see the PDM manual, Section 13 - Integrating devices.

9.8.2 Operation

PDM supports the Process Variables Root Menu, Diagnostic Root Menu and Device Root Menu
for online access to the device and the Offline Root Menu for offline configuration.

The classic approach for PDM is the offline operation with the PDM parameter table and the
transfer of entire configuration data sets with the "Download to Device" and "Upload to PG/PC"
functions. The parameter "Online Mode?" in the "Detailed Setup / HART" table section of the
parameter table should be set to "no". However PDM also supports online operation from the
"Device" and the "View" sections of the menu bar which is more similar to manual device control
using the keyboard. Usually offline and online configuration data sets are separated in PDM. Still
there is some interdependency e.g. regarding evaluation of parameter and menu conditionals: If
e.g. the "Access Level" is changed in an online menu the offline configuration data set needs to
be updated with "Upload to PG/PC" before the related online menus actually become accessible.

The help attribute of each parameter contains its function number as a reference to the local
device display and the handbook.

Parameter protection for custody transfer and service is the same as on the device's local
display. Other specific protective functions such as the passwords for the quick setup menu and
the setup menu are not supported with HART
