Hardware in the loop

National Instruments'

 gives control system design and test engineers a link between the NI LabVIEW graphical development environment and The MathWorks Simulink software.

Engineers can use configuration-based functionality in the LabVIEW Simulation Interface Toolkit 3.0 to create custom hardware-in-the-loop test systems with the National Instruments I/O of their choice, including CAN, reconfigurable I/O (RIO) and CompactRIO FPGA-based I/O, in addition to existing NI data acquisition I/O support. The software’s configuration dialog allows engineers to generate VIs for real-time implementation by mapping I/O channels to model inports and outports.

With the LabVIEW Simulation Interface Toolkit, engineers can build custom LabVIEW user interfaces to view and control a Simulink model during run time. Engineers working with very large models now can use the LabVIEW Simulation Interface Toolkit to remap controls and indicators to different model parameters and signals during run time. With this ability, they can scale user interface size and complexity by reusing controls and indicators.
