Digital Transformation
However, for the diagnostic functionality part of the system, such as diagnostic
algorithms, specialized measurements
and plots, this is still separated from the
historian. However, even this has been
improved. Diagnostic plot functions
and their corresponding measurements
(FIG. 1) can now be accessed directly from
the historian user interface with a single
mouse click, as shown in FIG. 2.
One of the most important advances,
however, is that it is now possible to store
high-resolution vibration time waveforms in the historian database. This was
the initial stumbling block for CMS-data
historian integration; it has finally been
removed so all data can now be stored in
the historian, both scalar and dynamic
values. This means raw data in the historian can be re-processed by service
providers either as a second opinion, or
in the case where the normal diagnostic
specialists are unavailable. There is still
no standardized way of associating measurement configuration information to
the raw data stored in the historian, but
this is expected to change, as well.

Now, diagnostic services are not only
more readily available, but they can be
performed more reliably and accurately
(FIG. 3). The vast amount of process and
machine monitoring data in the historian
can now be analyzed by statistical analysis to further refine symptom detection
earlier and provide more reliable prognosis to service with greater lead-time. CMS
suppliers are now also offering automatic
diagnostic services through a cloudbased webserver, so no client diagnostic
server hardware or software is required.
This cloud can then be connected to the
historian as a seamless interface.
More and more historian-based condition monitoring applications are being
developed, such as specific monitoring
techniques like thermodynamic performance monitoring of turbomachinery, or
for specific machines, such as reciprocating compressors.
Another important area of improvement with historian-based condition
monitoring solution integration is the
expanded user base. More specialists can
contribute to the machine healthcare

knowledge base, and more stakeholders
who make important asset reliability decisions can have access to this information.
Takeaway. The IIoT has been the main

driver for successfully breaking down
proprietary interfaces in the information world for a large part of the industry, and the machine condition monitoring domain is no exception. As a result,
historian-base condition monitoring has
become much more intuitive, reliable,
transparent and widespread. A lot of work
remains to optimize the historian-based
condition monitoring solution, but this is
expected to be refined over time.

He has been with the company
for 30 yr and has worked with
developing machine monitoring
strategies and optimization
techniques for a wide range of machines. He now
works with strategic market development, analysis
and communications. He is also active in ISO
committees that create standards for condition
monitoring and diagnostics of machines.

LIVE WEBCAST

Tuesday, February 9, 2021 | 10 a.m. CST / 4 p.m. UTC

Prevention & Re-Work of Off-Spec Product
Andrew Gorin
Vertical Sales Manager - Refineries
Pall Corporation

Who doesn't dislike dealing with the inconvenience of off-spec product?
Sub-par product not only limits production but also requires a cost-effective
solution for rework/correction to be found and implemented quickly.
Join the webinar to learn best practices for ensuring the prevention of offspec products, with emphasis on products coming from amine treaters and
caustic treaters, as well as, steps you can take to bring off-spec product back
to appropriate quality should you encounter such an event.
