Creating FlexLogger Plug-in using LabVIEW Project Template

Updated Feb 19, 2026

Environment

Software

  • FlexLogger
  • FlexLogger Plug-In Development Kit
  • LabVIEW

The FlexLogger™ Plug-in Development Kit is a FlexLogger add-on designed for test engineers. You can use this add-on in LabVIEW to create plug-ins that perform custom in-line calculations and acquire data from third-party hardware devices.

This document introduces how to create plug-ins, directly accessible and usable in FlexLogger, from LabVIEW projects templates.

 

  1. To access FlexLogger Plug-in template in LabVIEW, you need to install FlexLogger Plugin Development Kit. Launch NI Package Manager and search for FlexLogger Plugin Development Kit.
    1. Check FlexLogger Plug-in Development Kit Compatibility with FlexLogger and LabVIEW.

Goal
Pug-in Template   		  Data Flow
Create a plug-in that sends a setpoint value
you enter in FlexLogger to a plug-in
channel. A setpoint can have one value at a time.

Control a third-party instrument with
FlexLogger. For more information, refer to
Read Setpoint Channels from FlexLogger. section 		Consume
setpoint data		User input → plug-in

Create a plug-in that consumes one or
more waveforms from FlexLogger
channels, performs a custom calculation,
and produces a waveform of resulting data
that can be logged in FlexLogger.

In the template plugin,
Calculates the minimum or maximum value of multiple input channels and produces a resulting waveform channel.
 		Perform
calculation		(a) FlexLogger →plug-in

and

(b) plug-in → FlexLogger

Create a plug-in that generates waveform
data and sends it to FlexLogger.

The template plugin generates data for two channels with a constant value of 0.
Produce data for
FlexLogger		plug-in → FlexLogger

                                         

  1.  (Optional) Customize your plug-in using the methods described in the Plug-in Development section here .
  2.  Expand Build specifications, click Build.

After the build, a folder containing the plugin's packed library and XML files will be generated in the "Destination path" specified above. FlexLogger loads plugins from this folder on startup.

The created Plugin can be checked in FlexLogger Channel Specifications tab from Add Channel >> Plug-in . If the newly created Plugin is not displayed, restart FlexLogger.
