The PXI(e)-272x is a test module that replicates the behavior of resistance-based inputs and outputs such as potentiometers, resistance temperature detectors (RTDs), voltage dividers, and bridge elements. PXI(e)-272x Programmable Resistor Module can be configurated and operated with NI-272x Reference VIs. This article explains how you can use this module in NI VeriStand.

For PXI-2720, PXI-2722, PXIe-2725, or PXIe-2727 in VeriStand no matter what type of Real-Time target (Pharlap RT or Linux RT Target) you are using in your VeriStand project, you can use the NI 272x Resistive Simulation Custom Device to control the 272x devices.

Please note that this custom device is provided as-is and is not supported by NI. You can download the nipkg file from NI 272x Resistive Simulation Custom Device for VeriStand 2019, 2020 and 2021 and from NI-272x-Resistive-Simulation-Custom-Device-2023-Later for VeriStand 2023, 2024 or you can download the source code. It includes a LabVIEW project configured with source distribution for the Configuration and Engine LLBs necessary to use the custom device in VeriStand. Build these LLBs in the LabVIEW version corresponding to the version of VeriStand you are using. Refer to Building a Custom Device for more information.
