TOPKAPI Vision 5
The new version of TOPKAPI is being prepared. Its most
obvious developments are its full opening to database
management systems, for archiving and running SQL
queries, as well as major upgrades of the graph manager.
DBMS opening
In TOPKAPI version 5, instead of using TOPKAPI’s
proprietary log files, you can use a commercial DB
manager (e.g. SQL Server, Oracle, MySQL), where TOPKAPI
records the data it generates. The data is then
accessible instantly for other applications in the
company’s global information management system.
Also, SQL queries allow displaying data not issued from
the supervision application, in the form of event lists,
bar graphs or trend curves.
A user interface provides simple management of queries
for selection and sorting on database information. For
example, an alarm window can show that a production line
stopped instantly after a fault occurred on another line
not managed by TOPKAPI.
TOPKAPI’s trend curves display both data of the process
supervised and values sampled outside TOPKAPI.
The developments implemented use Microsoft’s .net
environment, providing effective and robust access to
the database objects: tests show that 2 to 3000 events
per second can be saved by TOPKAPI in continuous
running, without causing an overload.
Such performance would not be possible without the .net
environment, which is why AREAL has considered that the
time was right to engage this major evolution.
To ensure perfect ascending compatibility and smooth
upgrading, the old and new logging modes can coexist.
Triggering criteria for logging are hardly modified, but
the data can be directed simultaneously to different
tables in different bases. Write requests generated by
basic setting can be customized to meet the most diverse
needs.

The principles for displaying the views (events and
curves) do not change basically, but the upgrade offers
the following benefits:
-Content customizing
-Broadening of selection and sorting possibilities
-Display of data from different tables and handling data
from third party applications.
Curves
The curve manager,
which becomes a genuine grapher made available to the
operator, has many new functions, coupled with the
summary functions. This allows more particularly to
perform calculations on the fly on raw data, aggregates
and summaries, as well as formulas with several
independent variables:
"future" curves,
allowing to manage and compare objectives/achievements
Dynamic multiple
variable calculations
Aggregate functions
over configurable periods (average, minimum, maximum,
standard deviation, integral,…)
Processing on request
(user) or background (resulting curves recorded
continuously)
New bar graphs
Direct display of
sample values
TOPKAPI mmi
TOPKAPI’s MMI
version ensures work floor operation at machine level
based on graphic mimic diagrams. It benefits from the
full power of TOPKAPI’s graphic editor, and allows
implementing man-machine interfaces at a very
advantageous cost.
After a few years
existence, TOPKAPI MMI has become even more attractive:
 The
development tool has become free
The internal
calculation functions have been extended
The operating tool
allows choosing within a global application the part of
the facility to be managed locally.
Thanks to these
evolutions, TOPKAPI Vision users no longer have to
transfer modifications made in the central supervision
application to each of the workshop terminal
applications: the central application is merely
network-copied to the different operator stations in the
workshop, which load only their specific, local, part.
