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.

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.			2
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.
