Siemens Uses CompactRIO, LabVIEW, and DIAdem to Determine the Root Cause of Damaging High-Voltage Transients

Figure 1: Semipermanent CompactRIO Installation in Denver Car 321 Propulsion/APS Compartment

"Perhaps the greatest benefit of CompactRIO is the FPGA/processor combination. The reconfigurable FPGA hardware achieves scope-like accuracy and rates while the processor manages extended and remote operation."

- Ryan Parkinson, Siemens

The Challenge:
Determining the source of electrical high-voltage transients to prevent light-rail car failure.

The Solution:
Combining the benefits of the field-programmable gate array (FPGA) and processor in NI CompactRIO hardware to create a rugged, semipermanent monitoring system that records multiple data formats and rates, synchronizes the data, and performs real-time analysis to remotely monitor sensors in an industrial environment for extended durations.
