2.3.6
HART
®
protocol
The Rosemount 936 uses the HART protocol.
This is a field communications protocol used to communicate between intelligent field
instruments and the host system.
HART is the global standard for smart instrumentation, and most smart field devices
installed in plants worldwide are HART-enabled. HART technology is easy to use and very
reliable.
Through the HART connection, the detector can:
•
Set up
•
Troubleshoot
•
Display health and status
You can connect the HART communication on the 0-20 mA line or thought the intrinsically
safe (I.S.) connection with a standard Field Communicator loaded with Emerson's host
software and attached by a special harness.
2.3.7
Modbus
®
RS-485
For more advanced communications, the Rosemount 936 has an RS-485 Modbus-
compatible output that provides data communication.
This feature enables simple commissioning, maintenance, and configuration.
2.3.8
Tilt mount
The stainless steel tilt mount provides a small installation footprint that can conform to
limited space constraints, while the sturdy construction maintains alignment even in
constant vibration.
The X and Y axis adjustments provide quick and easy alignment for installation and
maintenance.
