The Simatic PDM is a PC application from Siemens for configuring HART ® and PROFIBUS
devices. For adaptation to different devices Simatic PDM uses Device Descriptions (DD).
The transmitter DD has to be installed on the PDM System and a so called "Device Install HART
PDM" is needed (available as download on the internet).
For installing the DD on PDM refer to the "PDM Manual" section 13:"Integrating Devices".Please
read also the "readme.txt", which is also contained in the "Device Install".
The transmitter DD for PDM can also be downloaded from our website. For information about
installing, follow the instructions in the attached "readme.txt" file.
PDM supports the "EDDL Process Variables Root Menu", the "Diagnostic Root Menu" and the
"Device Root Menu" for online access to the device. Furthermore it supports the "Offline Root
Menu" for offline configuration.
5.3.4 Configuration with PACTware
PACTware is a DTM/FDT enabled PC software, which can be downloaded for free on the Internet.
To be able to configure the transmitters via PACTware, download the transmitter DTM (Device
Type Manager) file from our website. For information about installing, follow the instructions in
the attached "readme.txt" file.
5.4 Current output and HART ® dynamic/device variables
The transmitters handle up to seven measurement-related HART ® device variables. These
variables depend on the device’s sensor configuration and each variable is represented by an
output signal of 4...20 mA. See the following table for more information.
