Appendix: HART Specific Information
13.1 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 op-
tion, 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 De-
velopers, System Integrators and knowledgeable End Users. It also provides func-
tional specifications [e.g., commands, enumerations and performance
requirements] used during Field Device deployment, maintenance, testing, and op-
erations. It is recommended that the 4-20 mA output be the primary gas monitoring
signal. The HART signal can be the secondary method.
ATEX applications
HART shall only be used for ULTIMA configuration, calibration or diag-
nostics. For safety relevant applications, the 4-20 mA analogue output
shall be used for measuring values.
The two-wire units’ HART protocol does not comply fully with Immunity
Standards EN61000-4-3 [2006] and EN61000-4-6 [2007].
