Integrating TwinCAT RealTime with Labview - Chris Knight
Просмотров 1,2 тыс.Год назад
TwinCAT is a real time operating system used in industrial applications, projects are developed through Visual Studio. This means the projects have a very defined structure which can be accessed programmatically through the Automation Interface. In this talk we will see how LabVIEW can be used to create, configure and deploy TwinCAT projects to real time targets directly without having to use t...
Bringing Labview and MATLAB together in a PLC environment - Chris Knight
Просмотров 258Год назад
This presentation introduces Beckhoff’s TwinCAT OS, a PC based automation platform. TwinCAT allows you to make use of standard PLC languages on the same platform that can implement MATLAB, C and LabVIEW. It provides a suite of tools for OPC UA, MQTT communications, measurement and data acquisition tools and a real time Machine Learning inference engine.
Using CODESYS IDE to interface with NI FPGA via IEC 61131-3 - Nick Powley
Просмотров 234Год назад
Often, there is cross-over between when using an NI cRIO vs PLC and remote IO makes sense for measurement control applications. One of the choices involved is from a software perspective of using LabVIEW Real-Time vs more traditional PLC programming. IEC-61131-3 is an international standard for programming PLCs, and defines language aspects such as ladder logic and function block diagrams. This...
Managing package requirements per project in LabVIEW - Stefan Lemmens
Просмотров 69Год назад
Every project is different and therefore has different dependencies. We love to package and reuse our code as much as possible but not all projects need the same reuse code nor the same version of those packages. So wouldn't it be better to deploy packages per project instead of per LabVIEW version. This presentation will briefly describe how others have tried to solve this problem and how we d...
Automated GUI testing with LabVIEW - Sam Sharp
Просмотров 4652 года назад
The LabVIEW community has more automated testing capabilities than ever before with increased adoption of unit testing, VI analyser and continuous integration. In this presentation we'll take this a step further and look at how you can use industry-standard software testing tools to automate testing of your built LabVIEW applications. This can significantly reduce manual test time and increase ...

User Events: The WORST named feature in LabVIEW??? - John Medland
thanks, I learned a lot from this video.
Very interesting talk, thank you for the upload. Is the project (or a simpler example of the channel wire approach to parallelisation) available anywhere to be downloaded? Thanks again
I have a question on how you add the GUI interactions in this to simulate button presses. Is it done through TCP -> test interface -> vi server -> find control and click?
There's a few different options: - TestComplete has an optional OCR and image module that can find text/graphics on the screen (e.g. button labels) and use that to find and click them. That's what was demonstrated in this example. - Using known coordinates of the buttons (e.g. click at [X,Y]) - Using VI Server to return the desktop-relative position of the control and then use that for the click location - this is what we mostly do now to make it more robust to GUI changes, but the code for converting sub-panel/pane/panel coordinates to screen coordinates can be a little tricky (there are some VI Server methods you'll need) - You could also add a Test Interface method to click the button (value signalling event), depending on the setup of your code
Error wire MUST be a CLASS. Until then, enjoy your obsolete trash development, made as a service by greedy managers
Thanks for the cool video!! I want to see how to make an error routine that IMPROVES the example at 1:00 or t= 2690 ruclips.net/video/W1egwquZ4ow/видео.html I want to have the error trigger a supression of the error and then use the LAST GOOD VALUE and pass it through. I COULD fix it on the FRONT END by giving the serial handler 4 tries to get the variable... I am VERY CURIOUS how to set up a handler that has, say, 5 elements in an array,, 10,20,30,40,50 and they are all reading happily but I get an error on the third and instead of 30n I get 0, I want to take the last good read of that array set and parst out the 30 and pass it on and supress the error and lob them so I can tell what is going on.
Hey all! i do have a machine with all software except the deployment license. do i need to buy it separately? then download a specific file? I have a 2019 platform software bundle.
Hi Jorge, this is probably best asked to NI support, have you tried them?
There is a point in this video where we lost internet connection and the recording stopped and restarted, apologies about this, hopefully it doesn't takeaway from the content
Nice. I personally like to create a gvl Map that stores user event references as a value with the name of the loop as a key. Each while loop will have its own user event. This eliminates the cluttered reference wire at the front and make the ui look seemless. If I want to send a message I simply type LoopName.Message + wire the variant payload on the sender VI. The sender VI will parse the string, look for the event refere to the loop in the gvl map and generate an event for it. I also invert the event driven state machine by putting the case structure inside the custom user event, event case. There are 0 wires between loops.
Hey Chud. The code in this presentation was just meant as a first introduction. Certainly in production grade code things should be packaged up more neatly. In general my messages are strickly typed as I think this is a powerful developer aid, so I never expose the variant.
exactly what I was looking for; is the slide set disclosed somewhere?
how to control a labview system with a mobile application
Do we need to install python after we build LabVIEW app?
I good morning anta yudi. The examples only work, if when you run the LabVIEW program, the python interpreter is already installed. Furthermore, to open a Python session it is mandatory to specify the version of the installed interpreter (the location is not mandatory as it can be deduced from the name of the desired version). Hope this clarifies your doubt Kind regards Luis Noites (CLD / CPI)
Very good thoughts on error handling strategies from someone who has clearly "been there, done that" on mission critical code. Beyond the useful content, this guy does a great job teaching and speaking about what he knows, a rare combination, keep up the good work sir.

Lots of useful information. Thanks!
Very useful. Thanks!
I am one of those LinkedIn guys that was surprised to hear Mark's mention of '8 types of error handling'. Finally got around to browsing around for it and found this gem. Looks I've been doing most of these things but without a comprehensive, structured way of thinking and approaching it. This is invaluable for planning- many thanks, Mark!
Glad it was of use, it is always good to get clarification that you are using effective approaches for things!
🙌🏻 very useful information
Glad you found it of interest!
