12 DIAGNOSTIC FEATURES
12.1 Positioner Diagnostic Levels
The Logix 520MD+ digital positioners have three levels of
diagnostics, “Standard”, “Advanced”, and “Pro”.
•
“Standard” diagnostics provide complete position-
related diagnostics and data.
•
“Advanced” diagnostics provide additional pressure
data.
•
“Pro” diagnostics enhance the off-line tests with
additional force data, and provide powerful on-line
monitoring capabilities including friction, data logging
functions,
and
comprehensive
system
health
information.
12.2 DTM Diagnostic Levels
The DTM is not required for the positioner to function, but
the graphical capabilities of the DTM allow for a richer
interface and additional functionality, including viewing the
dashboard, charts, annunciator panel, test comparisons,
and data logs and printing reports.
The DTM also comes in two versions: “Basic” and
“Advanced”.
•
The “Basic” DTM provides an intuitive, easy-to-use
user interface to the positioner. It includes calibration,
configuration, auxiliary card information and off-line
diagnostic tests. A dashboard gives a quick view of
important information.
•
The “Advanced” DTM provides a view of the
positioner’s full health analysis and interfaces to all of
the positioner’s “Pro” diagnostic functionality.
It is generally wise to use the Advanced DTM with the
Advanced and Pro positioners.
