Operating functions through HART communication

Condition
You can operate the transmitter through HART communication. The following is required for
this purpose:
● A HART communicator or PC software such as SIMATIC PDM.
● A HART modem to connect a PC with the transmitter or a lead to connect a HART
Introduction
The full functionality of the transmitter is available via HART communication. The HART
communicator and PC software are not supplied with the transmitter. How to connect and
operate a HART communicator or the PC software is described in separate operating
instructions or in the online help for both these tools.
Fundamental description
The input signal is provided in the form of digital information in the following variables
through HART communication:
● Pressure
● Level
● Volume
● Mass
● Volumetric flow
● Mass flow rate
● User programmable "characteristic curve"
As soon as you have set up the HART communication and the transmitter, you can adapt the
transmitter to your relevant measuring task. When doing so you are assisted by the
selectable measuring modes "Pressure", "Level", "Flow rate" and a user programmable
"Characteristic curve". One or more device variables are permanently allocated to each
measuring mode in order to execute corresponding measuring tasks.
