4.6 Introducing HART Communication

The HART communication protocol (Highway Addressable
Remote Transducer) is a hybrid analog and digital industrial
automation protocol. Its most notable advantage is that it
allows remote configuration of LLT100 instruments over legacy
4 – 20 mA analog device current loops, sharing the pair of
wires used by analog-only host systems.
ABB provides a HART communication package for the LLT100.
Once installed in your preferred HART application, it will allow
communication with your LLT100 instruments.
The ABB HART communication package (RevXX.XX.XX_
XX.XX.XX) is located in the folder whose name ends with
DTM_LLT100_HART_Laser_Level.
NOTICE
The communication board for HART (behind the
interface board) can not be replaced in the field, and
can not be moved between LLT100 instruments. In case
of failure, the LLT100 instrument must be sent back to
ABB for calibration and repair.
