NI’s Compact RIO platform is great for projects that need essentially a small PXI. Combining a cRIO controller with the multitude of C Series modules creates a functional real-time controller for many applications in a small footprint. The cRIO is often used as a standalone system, and even as an embedded system as part of an OEM machine. The FPGA built into cRIO offers very fast control loops for situations needing rapid response outputs. cRIO can make a symbiotic addition to a PC-based application that requires some aspect to be real-time.
Viewpoint has used the cRIO in applications that need a moderately powerful controller to perform real-time monitoring and sometimes control as well. Coupling the variety of C Series modules with LabVIEW RT and LabVIEW FPGA allows us to support many types of real-time applications:
- Product validation
- Endurance testing
- Machine monitoring
- Production testing.
Adding the cRIO’s FPGA capabilities opens up those applications to very fast control loops (100+ kHz) and essentially hardware-driven control and monitoring for critical applications with expensive assets.
