National Instruments PCIe-7851 Multifunction Reconfigurable I/O Device
The PCIe-7851 (Part Number: 781102-01) has a flexible usefulness that permits the instrument to coordinate individual application necessities and to impersonate the usefulness of settled I/O gadgets. For instance, the user can arrange an R Series gadget in one application for three 32-bit quadrature encoders and after that reconfigure the R Series gadget in another application for eight 16-bit occasion counters. The user can additionally utilize the R Series gadget with the LabVIEW Real-Time Module in timing and activating applications, like control and hardware-in-the-loop (HIL) reenactments. For instance, the user can arrange the PCIe-7851 for a solitary planned circle in one application, then reconfigure the gadget in another application for four free coordinated circles with partitioned I/O assets.
The user can make their own custom estimations by utilizing the settled I/O resources. For instance, one application may require an occasion counter that adds when a rising edge shows up on any of three advanced info lines. With a NI PCIe-7851 R Series gadget, another application may require a computerized line to be stated after a simple info surpasses a programmable edge. The user can actualize these practices in the equipment for quick, deterministic execution. The user can execute LabVIEW rationale and handling in the FPGA of the R Series gadget. Regular rationale capacities incorporate Boolean activities, correlations, and essential numerical tasks. The user can actualize different capacities proficiently in a similar plan, working successively or in parallel. In addition, it is plausible to actualize more intricate calculations, such as control circles.
