Starting
in 1981, before the Plant Information (PI) System became commercially
available, EXELE was contracted by OSI Software, Inc., (formerly Oil
Systems, Inc.) to perform some prototyping on early versions of the product
that would eventually become the PI System.
As a result, in 1986, when OSI sold one of its first large,
international systems to Statoil of Norway,
EXELE was contracted to act as OSI’s systems integrator.
Since then, EXELE has been involved with the configuration,
installation, and integration of over 100 PI Systems worldwide for many of
OSI’s customers. In addition,
EXELE has been called upon by OSI to develop and modify software products
that OSI now sells including ProcessTemplates, interfaces such as the CHIP,
TIWAY, Texas
Instrument D/3, Varec 4, Varec 5, L&J, and others.
Due to EXELE’s extensive batch expertise, OSI contracted EXELE to
write the original Batch Trend Package whose design features are still being
used in the product today. EXELE
has worked with virtually every client and server product that OSI offers,
on both PI 2 and PI 3 Systems, and on practically every hardware platform
that runs PI.
More recently, EXELE worked with some of
the worlds largest refineries to convert thousands of process
calculations to run against various OPC data sources. Part of this work
involved converting many interfaces to send data to OPC-based process
historians.
EXELE
has been an Authorized PI Distributor since 1988, has performed PI training
since 1990, and has OSI Certified Installers.
EXELE has developed a complete
suite of products to enhance PI
and OPC.
EXELE
has developed extensive client and server based
custom applications for Windows, Unix and VMS and has developed
several custom interfaces.
EXELE has configured PI databases for many of its clients.
As part of this activity, EXELE has performed point configuration, PI
data compression tuning, and interface configuration.
