6 Principles of Operation
1.4.3 HART Protocol
The 40/40 Flame Detectors use the HART protocol.
HART Communication is a bi-directional industrial field communication
protocol used to communicate between intelligent field instruments and host
systems. HART is the global standard for smart process instrumentation and
the majority of smart field devices installed in plants worldwide are HART-
enabled. HART is available in wiring options 2 and 3, see Table 1, page 3.
HART technology is easy to use and very reliable.
Through the HART connection, you are able to perform:
 Detector set-up
 Detector troubleshooting
 Detector health and status
For more details, refer to the HART Manual TM 777030.
1.4.4 RS-485 Modbus
For more advanced communications, the 40/40UFL detector has an RS-485
Modbus-compatible output that provides data communication from a
network (up to 247 detectors) to a host computer or universal controller for
central monitoring. This feature allows for reduced installation costs, easy
maintenance and local or remote diagnostic tools.
