VTRIP

Transient Recorder for Improving Processes

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 false conclusions.

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 SCADA system.

With VTRIP you can

Collect data at rates greatly exceeding 2,000,000 values/second
Store data to disk in a circular buffer sized for the data disk(s)
Analyze data graphically
Export data to other analysis products
Automatically save data permanently from abnormal events

Example system:

2.4 GHz Pentium PC with Linux and Vsystem
64-channel, 12-bit AD PCI I/O board
2 x 250 gigabyte data disks
Continuous recording of 1 million samples/second over 8 channels--PCI board maximum rate
Expandable with more I/O boards
98% of CPU unused !
