4.1 Overview
This section contains information on the HART Device Description Language (DDL) format used to
configure the Rosemount 975 Flame Detector.
4.2 HART protocol
The HART protocol incorporates a concept called the Device Description Language that enables all
suppliers of HART instruments to define and document their products in a single consistent format. This
format is readable by handheld communicators, computers, and other process interface devices,
regardless of manufacturer, providing full functionality from any HART device.
Note
For full compliance with the HART Host application, install a Rosemount 975 Flame Detector Device

The Rosemount 975 Flame Detector Device Description enables presenting the HART menu in a
graphical mode. This option is not supported by all hosts manufacturers. Refer to the HART host
