HART communication between a PC communicator and a pressure
transmitter
When parameterizing with a PC, the connection is made through
a HART modem.
The signals needed for communication in conformity with the
HART 5.x or 6.x protocols are superimposed on the output cur-
rent using the Frequency Shift Keying (FSK) method.

SITRANS P300 and DS III series
with PMC connection – Technical description
Parameterization through PROFIBUS PA interface
Fully digital communication through PROFIBUS PA, profile 3.0, is
particularly user-friendly. The PROFIBUS puts the DS III PA is in
connection with a process control system, e.g. SIMATIC PSC 7.
Communication is possible even in a potentially explosive envi-
ronment.
For parameterization through PROFIBUS you need suitable soft-
ware, e.g. SIMATIC PDM (Process Device Manager).
Parameterization through FOUNDATION Fieldbus Interface
Fully digital communication through FOUNDATION Fieldbus is
particularly user-friendly. Through the FOUNDATION Fieldbus
the DS III FF is connected to a process control system. Commu-
nication is possible even in a potentially explosive environment.
For parameterization through the FOUNDATION Fieldbus you
need suitable software, e.g. National Instruments Configurator.
