Free Start-Up Kit Delivers Time Interval Analysis Functions to NI LabVIEW

11/20/2002 - National Instruments extends the power of LabVIEW with the new Digital Time Interval Analyzer Start-Up Kit. With this free kit, the LabVIEW graphical development environment functions as a digital time interval analyzer, monitoring digital devices, such as relays and solenoids, and logging the times of the digital state changes to disk.

The start-up kit logs the relative times of state changes, rather than continuously polling, which decreases the load on the computer bus, frees CPU time, and minimizes the space required for log file storage. Engineers can combine the power of LabVIEW with digital I/O and counter/timer devices to simplify configuration and lower costs. With the open solution, engineers can customize their LabVIEW application to monitor more digital lines, add analysis functions, or connect to other I/O devices. LabVIEW also provides the option of adding tags and alarms to notify an operator when a digital state change occurs, which often represents a fault in the monitored system.

The sequence of event recording functions of the start-up kit make it ideal for a variety of applications, including manufacturing machine monitoring, power monitoring, and electrical switchyard monitoring.

The start-up kit works with LabVIEW 6i or higher and NI-DAQ 6.9 or higher driver software. Engineers can use the start-up kit with the NI 653x, a 32-bit digital pattern I/O and handshaking device, and an NI 660x 32-bit counter/timer device. The 653x digital device captures the line state changes, and the NI 660x counter/timer timestamps those changes. The two devices share timing and synchronization signals across the PXI Trigger Bus or RTSI bus. Both devices are available for PXI/CompactPCI and PCI.
