cRIO FaultSim6

The “cRIO FaultSim6” enables realistic simulation of electrical small-signal faults in National Instruments CompactRIO systems. It was specifically designed for simulating fault patterns in combination with the cRIO modules “cRIO Resolver Simulator” and “cRIO Position Sensor Simulation”.

However, it can also be used on its own to simulate fault conditions in a wide range of test environments and provides an accurate reproduction of fault conditions for functional, end-of-line or lifetime tests.

Technical description

The FaultSim6 module simulates electrical small-signal faults and is used to extend testing capabilities in combination with the cRIO modules “cRIO Resolver Simulator” and “cRIO Position Sensor Simulation”. It enables the simulation of various fault patterns such as:

• Short circuit (e.g. to ground or to another line)
• Line interruption
• Interference from noise or signal distortion

By combining several modules, different test configurations can be realized. The various fault conditions can be implemented via two fault buses.

The fault bus on a fault simulation card (often used in the electronics and automotive industries) is a dedicated wiring system designed to deliberately simulate fault conditions in electrical circuits or control units.

Applications

Simulation of fault patterns in combination with cRIO modules: In combination with the “cRIO Resolver Simulator” and “cRIO Position Sensor Simulation”, the FaultSim6 enables precise simulation of fault conditions, e.g. in functional, end-of-line and lifetime tests.

Standalone fault simulation in test environments: The module can be used independently to precisely simulate various small-signal fault patterns, testing the robustness and functionality of control units and sensors.

Medical technology: Validation of devices operating in safety-critical environments.

Thanks to its flexible configuration and integration into existing systems, the “cRIO FaultSim6” module offers an efficient solution for simulating fault patterns, both on its own and in combination with the cRIO modules “cRIO Resolver Simulator” and “cRIO Position Sensor Simulation”, in a wide range of industrial applications.
