Product Introduction
The NI PXI-8517 is a 2-port PXI FlexRay interface module designed for developing, testing, monitoring, and validating FlexRay-based automotive and embedded communication systems.
As part of the NI-XNET platform, the PXI-8517 is optimized for applications requiring deterministic, high-speed manipulation of large numbers of FlexRay frames and signals. Typical applications include hardware-in-the-loop (HIL) simulation, electronic control unit (ECU) testing, rapid control prototyping, vehicle network monitoring, automated validation, and automotive communication development.
The PXI-8517 provides two fully functional FlexRay interfaces. These interfaces can be used together for FlexRay development or independently to connect two separate FlexRay networks while maintaining full performance on each interface.
Product Overview
The National Instruments PXI-8517 provides FlexRay communication capability within a modular PXI test system. It combines dual FlexRay interfaces with NI-XNET software support and PXI synchronization features, making it particularly suitable for automated automotive test systems.
Each interface supports the FlexRay communication protocol and can be used for transmitting, receiving, monitoring, and manipulating FlexRay frames and signals in real time.
Because the PXI-8517 contains two independent FlexRay interfaces, engineers can connect an individual ECU when additional cold-start nodes are unavailable or use the two interfaces to communicate with separate FlexRay networks.
