HART Specific Information
HART Field Device Specification
The Ultima X Series Gas Monitor is available with an optional HART
(Highway Addressable Remote Transducer) output communications
protocol. With this option, the Ultima X Series Gas Monitor complies
with HART Protocol Revision 7 and uses the 16-bit manufacturer and
device codes. This document specifies all the device specific features
and documents HART Protocol implementation details (e.g., the
Engineering Unit Codes supported). These specifications assume
the reader is somewhat familiar with HART Protocol requirements
and terminology.
This specification is a technical reference for HART-capable HOST
Application Developers, System Integrators and knowledgeable End
Users. It also provides functional specifications (e.g., commands,
enumerations and performance requirements) used during Field Device
deployment, maintenance, testing, and operations. It is recommended
that the 4-20 mA output be the primary gas monitoring signal. The
HART signal can be the secondary method.
NOTE: The two-wire units’ HART protocol does not comply fully
with Immunity Standards EN61000-4-3 (2006)
and EN61000-4-6 (2007).
