KAPPA Server/KAPPA Client (Ks/Kc) workflow
KAPPA Server runs continuously on Windows
Server™and is controlled using KAPPA client (Kc) or a
WEB client. Data tags in the historian are persistently
connected from which data is sequentially mirrored,
filtered and presented to the user in a logical user-
defined hierarchy. Updates, filtering and specific
selection may be user-controlled or automatic.
The filtered data is stored in the local database to be
subsequently sent to the KAPPA analysis modules
on a single drag-drop or to third party workflows.
KAPPA Server stores KAPPA technical objects and
files to be shared by the analysis modules.
Connecting to data
There is no standard way to store PDG data. Almost
every vendor has its own data model, and OPCOs
routinely have several providers as well as their own
data model. Each data model requires an adaptor
to navigate and access data. An API permits the
development and connection to customized adaptors
that are automatically downloaded. Connection is
therefore very straightforward.
Data processing
When connecting to a new tag KAPPA Server
proceeds with a quick data scan of one point in every
ten thousand to preview the data and help in spotting
anomalies and gross errors. A user defined data
window can immediately discard obvious outliers. A
first series of points, typically 100,000, or one week
of data, is then used in an interactive session for the
engineer to adjust the wavelet setting and data post-
filtering, based on a maximum
Δ
t and
Δ
p. Upon user
acceptance the filtering is performed using overlapping
increments the size of the initial sample.
Derived channels (Mathpack)
These are user defined and permit mathematical
operations on data channels with a comprehensive
formulae package. The outcome may be another data
set or a Boolean function of time that may be used to
create an alarm. The outcome of the alarm is to display,
in the KAPPA client window, the execution of an alarm
E-mail, or the call of a user defined DLL.
