This window provides tools for quickly checking the device
state and all diagnosis information and tools. This window
provides realtime information of the device, measured
performance data, historical data and possibility to run
selfdiagnostics in the form of offline tests. This window
also has event log, which shows a log of events and actions,

13.5.3.2 Online Valve Signature
Fig. 64
Online Valve Signature feature shows the friction of the
control valve under normal process conditions when ever
the valve is changing position.Online Valve Signature shows
the amount of pressure required to move the valve in rela
tion to the valve opening. The device data is continuously
updated. To view the data in the DTM, read the data from
the device. The graph shows opening and closing pressures.
When the data has been read from the device, DTM auto
matically saves the graph to the database.
Advanced diagnostics
Comparison of two selected online valve signatures based
on the time stamp is available in advanced diagnostics
version of NDX.

Monitoring
Fig. 65
Monitoring view will automatically poll eight device vari
ables in approximately every 1.5 seconds. All parameters
are uploaded regardless the state of the checkboxes. With
the checkboxes under the monitoring graphs, user can
filter out unwanted information. All parameters are also
automatically logged to a log file. The log file location is
determined by Metso Device DTM Configuration utility,
which can be found from the Windows Start menu. The
default location for the log file is: C:\ProgramData\Metso\
NDX Device DTM\Data.
