|When production does not go as
expected, you need to understand the reason why.
And for that, you need good data. Once you
understand the problem, you can improve the plant
and its operation to increase overall
productivity and quality. "Good data"
requires a historical record that covers the
plant and process fully--both in the number of
signals and in the time domain. If some things
change in milliseconds or less, data recorded at
less than the Nyquist frequency will not give the
answers you need and can sometimes even lead to
Vista's VTRIP system is
based on Vsystem running on one or more computers
that are configured for a specific application.
Many systems will use VME or PCI as the base I/O
system, but systems can also be configured based
on other computer and I/O systems.
For the highest performance
and determinacy, VTRIP systems will be configured
using multiprocessor computers running real-time
UNIX or a real-time Linux. For high- and
medium-performance systems, the configuration
will be based on processors running either Intel
X86 Linux or Windows.
Because of the different
performance requirements, systems will be quoted
against the requirements and may include
additional PCs or workstations for monitoring the
system and data analysis.
With the use of Vsystem,
you can configure Vtrip to be a complete process
