The combination of these internal tests and diagnostics
messages offer a valuable proactive method of troubleshoot-
ing. The device not only tells the user what is wrong, but
also, and more importantly, offers suggestions on how to
solve the problem.
All of this information can be obtained directly from the
transmitter on the LCD, or remotely by using a HART
communicator or PACT
ware
and the ECLIPSE Model 700
DTM.

PC Program
The ECLIPSE Model 700 offers the ability to perform
more advanced diagnostics such as Trending and Echo
Curve analysis using PACT
ware
and a DTM. This is a pow-
erful troubleshooting tool that can aid in the resolution of
any diagnostic indicators that may appear.
Refer to section 4.0 “Advanced Configuration/
Troubleshooting Techniques” for additional information.
3.3.1 Diagnostics (Namur NE 107)
The ECLIPSE Model 700 transmitter includes an extensive
list of Diagnostic Indicators which follow the NAMUR NE
107 guidelines.
NAMUR is an international user association of automation
technology in process industries, whose goal is to promote
the interest of the process industry by pooling experiences
among its member companies. In doing so, this group
promotes international standards for devices, systems, and
technologies.
The objective of NAMUR NE 107 was essentially to make
maintenance more efficient by standardizing diagnostics
information from field devices. This was initially integrated
via F
OUNDATION
Fieldbus
™
, but the concept applies regard-
less of the communication protocol.
According to the NAMUR NE 107 recommendation, "Self
Monitoring and Diagnosis of Field Devices," fieldbus diag-
nostic results should be reliable and viewed in the context of
a given application. The document recommends categorizing
internal diagnostics into four standard status signals:
• Failure
• Function Check
• Out of Specification
• Maintenance required
These categories are shown by both symbols and colors,
depending on the display capability.
