LabVIEW is a graphical programming interface which can be used to communicate with any Thorlabs Kinesis®-compatible controller through the use of component Kinesis .NET controls. These .NET controls are a part of the Kinesis Motion Control software package.
This tutorial contains annotated LabVIEW VI examples for interfacing with Thorlabs’ Kinesis software. These examples make use of the Controls.dll file included with the Kinesis software installation package. This dynamic link library (DLL) assembly includes a collection of WinForms controls that hosts the Kinesis User Interface elements and underlying device functionality. These controls provide a straightforward way to start working with Thorlabs’ Kinesis software in LabVIEW.

LabVIEW
LabVIEW can be used to communicate with any Thorlabs Kinesis® compatible controller via Kinesis .NET dlls. Of the numerous dynamic link libraries (.dlls) included, the ‘Controls.dll’ provides a collection of .NET WinForms User Controls which can host the device user interface (UI) elements and provide access to the device methods and properties.
For example, the Kinesis graphical user interface (GUI) for the KDC101 K-Cube DC Servo controller is shown in Figure 1. This ‘View’ (UI), as seen in the Kinesis.exe application, can be hosted in the LabVIEW front panel, while providing the user access to back-end Kinesis .NET methods and properties in the LabVIEW block diagram.
By inserting the .NET ‘Controls.dll’ into the LabVIEW front panel, the user will be able to load a user interface for any Kinesis compatible device. Considering the example of a KDC101 K-Cube DC Servo controller, this device UI can be initialized by providing the serial number of the device and selecting CreateDevice(), as illustrated in Figure 2. This will create the device connection and display the UI seen in Figure 1.
Controllers that have a multi-channel architecture, such as the BSC202 Benchtop Controller and the MPZ601 Rack Module Controller, must also have the Channel Number specified. In the example shown in Figure 3, two separate UI panels are created (one for each channel) which can be operated independently of one another.
A range of downloadable, annotated example VIs can be found in the Example Vis tab. The examples provided are related to specific controllers and are organized by hardware type (i.e. Motor, Piezo and Piezo Motor, and Strain Gauge Reader). A Simulator VI is also provided which will enable connection to the Kinesis Simulator Application. The examples are saved as LabVIEW 2012 compatible examples.
For tips on building your own VIs with Thorlabs Motion Control Hardware, please see our comprehensive Kinesis LabVIEW Guide.
For any questions or comments about these examples, please contact Tech Support.

Figure 6: The Device ‘View’ Hosted in the Front Panel
Inserting a .NET Control
- Right-click on the front panel, then select '.NET container' and place the container on the front panel (Figure 4).
- Right-click on the .NET container and select 'Insert .NET control...'.
- In the 'Select .NET Control' window, click 'Browse...'.
- Browse for and select 'Thorlabs.MotionControl.Controls.dll', located in the user's LabVIEW project folder.
- In the 'Controls' list, select the controller that will be used (Figure 5).
- The LabVIEW front panel will now display the Kinesis device's user interface (Figure 6). The device methods and properties can now be accessed via the block diagram. Please note that the device UI will appear as ‘Disconnected’ until the VI is running and the control has been initialized.
Accessing a Property or Method
The Control reference node provides access to the Control methods and properties, such as CreateDevice() and CloseDevice(). Right-clicking the node will enable you to initialize or close communications with the device. CloseDevice() will close communications, shut down the .NET library, and reset the UI when the session terminates.
The Device methods and properties can be accessed through the Device property reference, as shown in Figure 7. In the case of T-cube and K-cube type devices, this property is 'Device'. In the case of Rack Module and Benchtop type hardware, device properties and methods can be accessed from the device type specific property label, i.e. 'ModularPiezo' or 'BenchtopStepperMotor', as shown in Figure 8.
Alternatively, LabVIEW .NET connectivity functions allow you to create and interact with the Kinesis .NET SDK. Through the Functions Palette, select "Connectivity > .NET" to access all functions used to interact with .NET objects (Figure 9).
For more information on LabVIEW .NET connectivity, please refer to the Kinesis LabVIEW guide.

Modular Rack and Benchtop Device Formats
Figure 10: Register Events Such as MotorStateUpdate in the Front Panel
Working with Events
An Event Callback VI is created using the Register Event Callback Function in LabVIEW. This will cause a VI to be called under specified conditions. Some basic events include Motor Status Updates (Figure 10), Connection Change Events, Settings Update Events, or Error Update Events. These events are detailed further in the Kinesis .NET API. An example of this is provided in the KDC101 Motor Status Changed tutorial where a programmed response appears when the Motor State changes.
The Kinesis DLLs (such as those contained in the partial list above) must be copied into your LabVIEW project folder.
Getting Started
Complete the following steps before using the example virtual instruments in the Example VIs tab:
- Install the Kinesis software. Ensure that the version of Kinesis/component DLLs is of the correct bit type, depending on the version of LabVIEW and the operating system. The included examples were built using Thorlabs' Motion Control Software v1.14.12.
- For the example VIs to run successfully, manually copy the component DLLs from the Kinesis install folder to the “Kinesis LabVIEW Examples” folder. The Controls.dll will typically require all Kinesis DLLs to be copied into the project folder.
- Open the VI through the 'LabVIEW Project Explorer' to correctly load the User Interface from the Thorlabs.MotionControl.Controls.dll.
Example VIs - Front Panel Overview
A LabVIEW VI contains two windows for building applications; a Front Panel and Block Diagram. The LabVIEW Front Panel contains the front end User Interface components of the VI. The Front Panel of each Example VI has been formatted to contain instructions and features which make these VIs easy-to-use. An overview of these features along with some of the key interface features of the LabVIEW Front Panel are outlined below.
Legend:
- LabVIEW Toolbar, Where the VI is Run
- Name of Device the Example Utilizes, Along with Webpage Link
- Introduction and Step-by-Step Instructions for the Example VI
- Functioning Front Panel Controls and Indicators (Please note that the device UI will appear as ‘Disconnected’ until the your VI is running and the control has been initialized.)

Many programming techniques are omitted for the sake of simplicity, such as setting directories and error handling.
Example VIs | ||
---|---|---|
Item #, Type | Example Name | Description |
Motor Controllers | ||
KDC101 K-Cube, Brushed DC Servo |
Build Device List | The example VIs require you to enter the serial number of your device manually. This VI, however, will build a list of connected devices and wait until the user has selected the serialized device to control. |
Connect | Demonstrates how to initialize communication with and then disconnect from the KDC101 in order to control DC brushed stages and actuators. | |
Get Position | Get Position will poll the device position through the GetPositionCounter() method which will output the stage position in device units. This can be converted from device units (encoder counts) to real world units (mm) by considering encoder counts per revolution of the motor, gearbox ratios and leadscrew pitch. | |
Motor Status Changed | This VI enables you to make use of motor events. These events include motor status updates, connection change events, settings update events, and error update events. This VI utilizes the motor status update. An event callback sub-VI is built using the register event callback function in LabVIEW. | |

While the focus of this tutorial is using the WinForms User Controls library (Controls.dll) as a straightforward way to load a UI panel and utilize Thorlabs' Kinesis hardware, it is possible to access the more advanced functionality contained within other .NET DLLs included with the Kinesis software installation. This functionality is outlined in detail within the Kinesis .NET API help file.
The following examples from the Example Vis tab make use of functionality outside of the Controls.dll library:
- KDC101 - No Front Panel
- BPC301 - Waveform LUT
- KPZ101 - Waveform LUT*
- KPZ101 w/ KSG101 - Set Position*
*These examples support previous-generation products that are no longer available for purchase.
The BuildDeviceList method can be accessed by dropping in a DeviceManagerCLI Constructor Node.

 (posted 2024-05-23 13:46:09.297) Is there an equivalent example VI for BBDx for setting trigger parameters?
I see there is one for KBD101 but I'm unable to find the same method or selection to set a trigger parameter for my BBD302. Thanks! Rayan Syed
 (posted 2024-05-22 11:23:54.62) I'm struggling to get Labview working, every time I run the program it says "No Suitable Devices Found." LabView and Kinesis has the same x64, the serial number is correct, and it shows up on Kinesis. Do you have any idea what else could be wrong? cstroud
 (posted 2024-05-30 11:52:54.0) Thanks for reaching out. I'm sorry that you're having issues with Kinesis and Labview, I will contact you directly to help troubleshoot this. Hyungchul Park

 (posted 2024-05-06 14:01:01.76) I am using Labview 2015 with KSG101 and KPZ101, and it seems that .Net control interface .dll file cannot be loaded. I believe many people who are using newer version of Labview experienced the same issue. May I get help to resolve the issue? cwright
 (posted 2024-05-10 09:39:34.0) Response from Charles at Thorlabs: Thank you for your comments. The cause for a .NET control not loading is that the incorrect bit version is being used or the .NET assemblies have not been copied over to the same directory as where the LabVIEW project is saved. For example, if you are using 32 bit LabVIEW for 64 Bit Windows you will need to use the corresponding 32 for 64 bit DLLS from the Kinesis software. William Keller
 (posted 2024-04-30 10:30:33.137) Was super easy to get 3 motor controllers going in LabVIEW 2019 using Kinesis, and has a good number of functions all packaged neatly into the .NET container, making it fast and easy to get up and running. But it seems like the .dll methods are designed to only run one command at a time - so rather than being able to move the stages diagonally (2+ axes at once), it has to finish moving one axis before moving the next one, so it wastes a significant amount of time when you have a large number of positions that the stages need to move to. cstroud
 (posted 2024-05-21 06:49:56.0) Thanks for reaching out. While most of the DLL's aren't designed for synchronous movement, simultaneous movement should be possible. I will contact you directly to send over some examples and discuss this further. Cheolhee Han

I have followed the instructions in the "Kinesis with LabVIEW" guide and constructed the virtual instrument just as presented. However, when I run the program the .NET object doesn't start up and the message "No Suitable Devices Found" pops out.
The Kinesis (1.14.36) program does recognize the KCube, but the LabVIEW .NET container never does. Any idea what might be happening? JReeder
 (posted 2023-01-19 10:34:52.0) Thank you for your enquiry. I have reached out to you directly to help troubleshoot the issues you are having. Common troubleshooting questions are as follows: Have you used the correct serial number? Are the bit versions of LabVIEW and Kinesis the same? Have you saved the LabVIEW project and is the VI being written as part of that project? Have you copied across all the DLLs using the DLL Utility to the folder where the project is saved? Richard Hainzl
 (posted 2022-09-07 13:48:24.08) I think it would good to have more complete examples for how to use the Kinesis motor controls from LabVIEW.
I would have been very happy if there would be examples for all ways of moving the motor and maybe some special cases where you want to interrupt the motion and what to do when there have been hickups. DJayasuriya

 (posted 2021-10-13 12:54:45.52) Hello,
I would like to use the .Net C# code for controlling Kinesis-based hardware. I would like to work with the Kinesis simulator at the beginning. I was able to run Kinesis simulator and Kinesis control software and control the simulated device.
I was trying to do a similar thing with the C# examples, but I was not able to connect to the simulated device. Are there any step-by-step examples of how to compile the C# example and control a simulated hardware?
Regards,
Lukasz cwright

Usually an inability to connect to a simulation is due to not having the simulation currently initialised in the Kinesis simulator or by having the Kinesis GUI, or other software, already accessing the simulation.

 (posted 2021-09-17 10:55:01.263) Hi. I purchased the Optical Delay ODL220(/M) and BBD301 Benchtop Controller from Thorlabs several weeks ago.
I need to read the phase-locked amplifier(SR830)'s data while the delay line is moving.Now,I know how to control the ODL by Kinesis® with LabVIEW and I can read the phase-locked amplifier(SR830)'s data by labview.
However,I can not read the phase-locked amplifier(SR830)'s data while the delay line is moving.Once the ODl starts running by Kinesis® with LabVIEW, the process reading the data is interrupted.
I need your help!Thank you! DJayasuriya

我目前正在进行对TSC系列的控制器使用LabVIEW进行二次开发。虽然使用例程中.net的方式能够很快在LabVIEW中实现控制界面。
但目前我期望可以通过LabVIEW中单独的布尔输入控制电磁阀的开闭,而不是.net界面。请问对于TSC系列的控制器可否实现此功能,若可以不知能否告知。若不可以,还希望能推荐一款可以实现该功能的控制器。谢谢!
祝好

 (posted 2021-08-09 19:27:08.707) I'm trying to transfer my labview project to another computer and when I load my VI I keep on getting the error message: "LabVIEW: File not found. The file might have been moved or deleted, or the file path might be incorrectly formatted for the operating system. For example, use \ as path separators on Windows, : on Ma OS X, and / on Linux. Verify that the path is correct using the command prompt or file explorer. The file 'Thorlabs.MotionControl.Controls.dll' could not be loaded."
I tried reinstalling the Kinesis software from the Thorlabs page, but that didn't help. I'm pretty sure I installed the correct software for my computer and labview. How can I fix this problem? cwright
 (posted 2021-08-12 06:27:11.0) Response from Charles at Thorlabs: Thank you for your query. This is not related to Kinesis but is LabVIEW telling you a file is not where it is supposed to be. The project will be expecting the VI to be in a specific location. If the path address is different to the old PC then this will occur. The project file does not contain the VIs themselves, only references to them, so if you only moved the project file then you must copy all the files across to the expected locations. R

 (posted 2021-08-12 06:42:04.0) Response from Charles at Thorlabs: Thank you for your query. I would expect the controller not being recognised. Please make sure you have put in the correct serial number of the K-cube rather than the stage. When requesting software support it is always best to contact technical support directly with a copy of the VI so we can view what you are doing. That will usually save a lot of time.

 (posted 2021-02-09 15:32:43.013) Hello, I've faced a similar issue as some people below. Are there updated .dll files for the 32 bit version of Kinesis for 64 bit windows? There's a discrepancy between the 64 and 32 bit assemblies. For instance, while there is a 64 bit version of Thorlabs.MotionControl.Controls.dll, there is not a 32 bit version, and it's causing the same "An error occurred trying to load the assembly" message to appear while I attempt to follow the guide and create a .NET control in the 32 bit version of LabVIEW 2020. cwright
 (posted 2021-02-10 09:38:31.0) Response from Charles at Thorlabs: Thank you for your query. There is a 32-bit Controls.dll in the newest install from the web. If the Thorlabs.MotionControl.Controls.dll or other dll's have not been installed this may be a result of having an old version already installed. Please completely uninstall and reinstall Kinesis. When copying the dll's over to the LabVIEW project folder, you can either do this manually or using the Kinesis DLL Copy Tool. WEN-RUEY Hwang
 (posted 2021-01-22 15:20:13.367) Hi,
I have the same error message when I insert "Thorlabs.MotiomControl.Cotrols(1.4.1.0)" I am running on the Labview 2020 and I downloaded "Kinesis 32-bit for 64-bit Windows" because my computer is 64-bit and the Labview 2020 is 32-bit. Can you explain why I still have the same error message. Do you have new .dll files for labview 2020 32-bit?
Thanks,
Wen-Ruey cwright
 (posted 2021-01-25 09:19:49.0) Response from Charles at Thorlabs: Thank you for your query. There are a few reasons as to why this error can occur, most commonly is that the incorrect bit version is being used. Another common reason for this error is that the .NET assemblies have not been copied over to the same directory as where the LabVIEW project is saved. We will reach out to you directly to help troubleshoot further. Sophie ROUGELOT

I followed the Kinesis LabView Guide and I get an error message at step 5 saying that "Une erreur a eu lieu au chargement de l'assembly" in the Controls window of the "Select .NET Control" dialog window.
I use Labview 2017 (32 bits).
Version of 'Thorlabs.MotionControl.Controls.dll' is 1.14.24.17290.
What do you think?
What could be the root cause?
Thank you.

 (posted 2021-01-12 04:46:08.0) Response from Charles at Thorlabs: Hello Sophie and thank you for your query. Receiving the error message 'An error occurred while loading the assembly' whilst trying to load a control into a .NET container is usually the result of trying to load a 64-bit .NET dll into a 32-bit version of LabVIEW or vice-versa. In your case please ensure you are using either Kinesis 32-bit for 32-bit Windows or Kinesis 32-bit for 64-bit Windows depending on the bit version of your OS. user

 (posted 2020-08-31 05:13:19.067) Hi,
I'm trying to control a LTS from LabVIEW.
I'm experiencing an "system.I0.FileNotFoundException" when I try to load the code from another project than the original one. I've created a project that contains the LV code that contains the .Net calls so that these can be used by other projects.
It appears that the .Net dll's need to be besides the project before all dll's are loaded. If I inspect the loaded .net assemblies in LV then the expected ones are loaded (the ones that I actually use). It also appears that some dll try's to load another DLL and does that relative to th e project file and not the already loaded Dll's.
To be clear, I can get the code to run if all the DLL's are located besides the project file. This however limits the re-use possibilities of the code.
How can I have only 1 set of DLL's and use the code in multiple LV projects? cwright
 (posted 2020-09-02 10:12:28.0) Response from Charles at Thorlabs: Hello and thank you for your query. Unfortunately our .dll files do require that they be copied into the same folder as the project calling them, as described in the Kinesis LabVIEW Guide which can be found on our site at the following link.

 (posted 2020-07-28 11:22:12.0) Response from Charles at Thorlabs: Thank you for your query. We will contact you directly to help diagnose the issue, however a common reason for receiving an error when loading dll's is due to using incompatible bit versions of Kinesis and LabVIEW. The Kinesis bit version should match that of your LabVIEW bit version. We provide 32-bit and 64-bit versions of Kinesis as well as a 32-bit for 64-bit Windows version for those running 32-bit LabVIEW on 64-bit Windows. user
