Basics of HART
13.10.1
Introduction
Description
Using HART functionality you can operate the anolog module additionally with digital
communication options. The HART protocol has developed into the "de facto" standard
protocol for communication with intelligent field devices: HART is a registered trademark of
the "HART Communication Foundation" (HCF), which holds all rights to the HART protocol.
Note
The HART analog module supports HART protocol Version 6.0

Properties of HART
Advantages of HART
Using HART analog modules has the following advantages:
● Compatible connection with the analog modules: current loop 4 - 20 mA
● Additional digital communication using the HART protocol
● Low energy requirements of HART, important for use in hazardous areas
● Numerous field devices with HART functions are in use
Typical applications of HART
● Commissioning of field devices (centralized parameter assignment)
● Online modification of field device parameters
● Information, maintenance and diagnostic displays for the field devices
