    Get the JKI State Machine Editor (just check VIPM for package updates) Version 2013.4.0.186 This new release adds a right-click option called "Find Data Accessors" to Bundle by Name and Unbundle by Name nodes in a JKI State Machine. Using this feature will open a dialog showing all the frames of the JKI State Machine that access the data, as shown below:

    I found one problem that occurs to me. "Find Data Accessors" is available in any VI (not only JKI State Machine) for the Unbudle by Name function, but its call does not cause the appropriate list to be displayed in the dialog box, although the application is started and consumes processor resources. Calling it several times on a notebook with an i5-4210M processor results in 100% CPU load. I've attached a screenshot for the FMSM example from LabVIEW example projects. As you can see, also Add Dynamic Events and JKI State Machine Editor... are visible - only when pop-up on Bundle/Unbundle by Name.

    I am using a class that I want to generate an xml to archive as final data. I can't just wire the class to the easy generate xml_jki Easy.vi. so I have to use a constant cluster and unbundle and rebundle. Is there an easier way to do this. Thanx Norm

    I have installed LABVIEW 2019, and I followed the procedures to make sure VIPM can communicate with VIPM 2018.0.0f2: https://support.jki.net/hc/en-us/articles/214135683-Resolving-issues-with-VIPM-connecting-to-LabVIEW But, still I do not see LABVIEW 2019 listed within the VIPM window: Any clue on how o solve this? Thanks

    Hello! Where can I download the latest versions of the state machine and the state machine editor as a vip file (there is no Internet access on that computer)? Or maybe you can get out of any directory when installing via vipm? https://github.com/JKISoftware/JKI-State-Machine/releases? here?

    Hi @Antoine Chalons. Yes, I can see how layers of nested array/cluster containers can be tricky 🙂 I'm glad you were able to figure it out, and get it working! Hope all is going well for you in general and on your LV projects.

    Open "Compare to Constant.xnode" with a text editor. Near the bottom, delete the two items "Untitled 4 (SubVI)" and "Untitled 5 (SubVI)" Then it will build.

    I had a separate QD plugin for this, but I can't find evidence that I ever shared it with the community. You've just given "ctrl+space ctrl+q" back to me. Thank you. However, mine puts it exactly eight pixels from the output tunnel and pre-wires an empty String constant... Another feature to add might be my JKI State Machine Follower. It activates the current Case Structure case while the VI is running. Maybe? You'll save me "ctrl+space ctrl+f"... Thanks for all your work on this, Jim

    single step sounds good - and should work in both direction Last/Next Step dynamic state generation - maybe JSON imported State"Objects" (export fct would be nice 2)

    Hi all, I have faced an issue with JKI VI Tester. Here are the details.. I am creating a DOM reference in "Setup.vi" and bundling it into my TestCase Object. DOM reference can be created by using "Load.vi" from XML Parser palette(attached image-> XML Parser palette and DOM Ref.png). When I unbundle it in the test VI, the DOM is reset to '0'. It is getting lost. We digged into the VI Tester and found out that some deprecated property nodes are used in "_JKI Toolkits\VI Tester\TestCase.llb\CallTestMethod.vi" in order to pass data from one VI (Setup VI) to another VI (Test VI).Refer to attached images -> VI Tester_Set Control.png, VI Tester_Get All.png. When the DOM reference is flattened it is getting lost, because LabVIEW doesn't know how to convert DOM reference into flattened data type. We have done a quick internal fix by replacing the property nodes and using variant to data after getting the control value. These changes are shown in "VI Tester_Set Changed.png" and "VI Tester_Get_Changed.png". Also, in "_JKI Toolkits\VI Tester\TestCase.llb\WaitOnTestComplete.vi", we have replaced the property node when parent data is written to child class indicator. This change is shown in "WaitOnTestComplete.png". I am getting my DOM reference in test VI correctly after doing this change. As I said this is a quick fix done for internal purpose. If this is the right change to make it work, can you please make this change and distribute the package so that my customers can also use it. If this is not the right change to be made, please suggest us how to fix this. Also, let me know if you can fix this issue and and release the fixed version. Please let me know if any other information is needed regarding this. Thanks, Bhargavi Gowri.

    Hello. I am trying to make a measurement program. Since this measurement takes a long time, it is necessary to be interrupted by the user's operation so that it can return to the measurement standby state. Is there a smarter way than inserting lots of checking the local variable of the break button during the measurement sequence?

    Hi @JimKring I have attached the sample project, which demonstrates the issue that I am facing. I have also attached the image, which shows the DOM ref values in New.vi of test suite and setUp.vi of the test case. Please let me know if you need any details. Thanks, Bhargavi Gowri.

    Hello, I am having trouble loading tests. When VI tester starts it doesn't find my tests. I can manually load 1 test by File/Open File or test class. I can't load multiple tests. I have my classes in folders. Do the test classes need to be in the top level of my project? I have them in a auto populating folder called "Unit tests? Thanks Dan

    @Robert Smith I know this is four years later and probably not very helpful, but I just used VI Tester for the first time and found that my tests would not appear in the UI if the test classes were in auto-populating folders. This may have been your problem. Hopefully this helps someone else who might come across this thread.

    It would be great if there is a preview window along with the description editor. Right now, after formatting the description with various tags (like bold/italics etc.,) I would need to build the package in order to see the formatting. If there is a preview pane along with the description, it would easy to see the final formatting. Thanks, Ajay.

    I've got a problem with JKI SM Editor (JKI SM ver. 2018). In one case, it increases the CPU resources consumption. The procedure is as follow: 1. Open New VI or existing VI with JKI SM. 2. Open block diagram. 3. Open JKI SM Editor. 4. Close front panel of the VI. CPU usage increases - in my case (i5-4210M) up to 38 - 40%. Have to reset the LabVIEW. Has anyone observed silmilar behaviour? [Update: This has been fixed in version 2018.0.1.36 of the JKI State Machine package, which has been published and is available for download and installation using VIPM.]

    We figured it out -- it was getting an error during Macro Exit (shutdown), that was causing it to go into the error handler, which was going into Macro Exit (an infinite loop). You can work around this issue by tweaking the code inside the JKI SM Explorer window to look like the following. (You can open the JKI SM Explorer then press Ctrl+Space to stop the VI, then Ctrl+M to go into Edit mode). Update: This has been fixed in version 2018.0.1.36 of the JKI State Machine package, which has been published and is available for download and installation using VIPM.

    No, CPU usage is high all of the time. Yes, Mass Compile is enabled (always). I reinstalled JKI State Machine, but still nothing. So, I have to remember to close the Block Diagram first or JKI SM Editor (Explorer in fact...). Maybe it is important or not... my LabVIEW version is 2018 (18.0f2)

    The issue is because I renamed the event case to "Idle" from "" (empty string). Renaming the case name will resolve this issue.

    Hi, Please help... I am trying to create a .vip that will install my LabVIEW project as a LabVIEW project template (note: I have done this process a few time before with no issues) I have my project that I want to make into a template, everything works perfectly. I configure the .vipb, I build and install the .vip. I check the destination to see if my files have installed to the correct location, they have. Here's where the problem kicks in...... I open my LabVIEW project that has installed in the destination, and notice that the .png files in my project some are missing and some are saying missing. In my project I have .png files in various .lvlibs. The first .lvlib in the project has the .png's showing, however showing as missing and the expected location is saying C:\ which is incorrect, it should be in the location where my .lvlib is in the destination. The other .lvlib's don't even show the .pngs in the LabVIEW project explorer. Now checking on disk all the png's are there and in the correct location. In summary it looks as if as part of the vip install it is removing the link the .lvproj has to my .png files VI Package Manager Version : 2018.0.0f1 Jul 21 2018 LabVIEW Version : 2016 (32 bit) OS : Windows 10 Pro Version 1803 Any help is greatly appreciated Thanks in advance.

    Jim, Here is a simple example. Note it appears that also text files (and perhaps any non-LV files) are affected. The .vipb file is from 2017. Sam Simple Example.zip

    Is there a way to install all the packages into Labview 2018 that I already had in LV2017 (short of shift-clicking all the OpenG VI packages, then ctrl-clicking all the MGI packages and my favorite other goodies)? If it's part of VI Package Configurations, I might just upgrade.

    Sorry for my late answer, I am very bussy at work. Yes, I've tried. There a many placeholders. For examples: So, a lot of work to do. But OK. New technology (LV NXG), new philosophy, new tools... It is better to start the new project directly in NXG. But another problem in NXG 2.1. I have instaled JKI SM 2.0 and there is an option to start the new project with JKI SM. But... if I need to add JKI SM to new, empty VI I'm not able to do it. In new JKI SM project, there is also a lack of Close Reference in "Data: Cleanup" state. I am sorry for so many questions and comments, but I often use JKI SM and recommend it to my students as the next step with programming in LabVIEW (something more then a simple state machine).

    @Jim C you may want to tell your coworkers to sit down when the hear about this new release... We've made another great round of improvements to the JKI State Machine Editor that we're excited to tell you about. Integrated Event Structure and Case Structure Viewer The biggest thing you'll notice is that we've integrated the Event Structure and Case Structure into a single tree view -- all of the Event Structure frames have been added under the "Idle" ("Event Structure") item at the top of the tree (as shown in the screenshot below). You can now easily navigate all the Event Structure frames and Case Structure frames from this single tree view. Drag & drop to reorder the Event frames -- it works just as you'd expect! Context Help Shows Documentation for Frames of the JKI SM If you show the Context Help window (<Ctrl+H> or Help >> Show Context Help) and then hover over a frame name in the JKI State Machine Explorer's tree view, the Context Help window will update to show the documentation string for that frame. Explore States Dialog Another cool feature we added is the ability to Explore States on a state string constant. Simply right-click on a state string constant and choose Explore States (as shown below). This will open a dialog (shown below) that looks a lot like your string constant, and allows you to click on individual lines/states of the string constant, which will navigate the JKI State Machine to that frame. This allows you to quickly jump between frames if you'd like to navigate through the sequence of states in the string constant. Grouped Right-click Options on States Finally, we added a small usability improvement where we now group all of the right-click options for a state, under a single submenu (as shown below) -- previously, these were all at the root level and started to get unwieldy. I hope you enjoy this latest round of improvements to the JKI State Machine Editor and it helps your write great code even faster.

    Hi Jim, THANK YOU! That link did help! Looks like all I needed was to install libXinerama.so.1 WHICH I thought I had already but not for 32 bit! Installed, as a result: Installed: libXinerama.i686 0:1.1.3-2.1.el7 nvidia-x11-drv-32bit.x86_64 0:384.111-1.el7.elrepo Dependency Installed: libX11.i686 0:1.6.5-1.el7 libXau.i686 0:1.0.8-2.1.el7 libXext.i686 0:1.3.3-3.el7 libxcb.i686 0:1.12-1.el7 Didn't require the 2015 run-time install since 2017 pro dev is installed. VIPM is happily doing its package cache download stuff as I am typing this! What a lovely sight!!!! Thank you again! Cheers, Brian

    @Jim Kring Ahaaaa- in my case, that folder already existed from a previous install; and the jki.conf it contained was owned (755) by the previous user of my machine... I recursively gave myself permissions through the whole folder, which cured the error 8; however, VIPM would then launch, and die silently while still at the splash screen.. So I blow away the whole JKI folder, and everything went fine from a clean start ;-) -Thanks for your help! ~Tom

    I tried installing the new VIPM2017 for Linux in a clean Fedora 27 virtual machine just to give it a try but I can't get it to do anything. I followed the two basic steps: 1) install LVRTE 2015SP1 which installs without any problems or errors 2) copy JKI folder to /usr/local as described in the instruction.txt When launching vipm I just get the blunt error: No such file or directory as shown below sudo ./vipm sudo: unable to execute ./vipm: No such file or directory What could be the problem and how could it be resolved?

    I've been tasked with trying to build packages on MacOS, but so far I have not been able to successfully build anything. The builds complete without error, but when I try to open the packages I just built they do not contain any files. I'm running MacOS High Sierra which is not explicitly supported by any version of LabVIEW at the moment, but I'm using LabVIEW 2016. Has anyone successfully built packages on High Sierra?

    Whoops, my bad. I don't really know VIPM very well. My co worker wrote: "I think you're looking at a re-packaged version of JKI VI Tester for MacOS that I made locally. VI Tester still shouldn't be available for mac through VIPM. "

    I installed VIPM (2014 because that's the latest build for Mac) on MacOS. It's showing plenty of packages such as ones from NI, MGI, etc... But oddly, no JKI packages. So I can't find VI tester in the list. Any idea what could be causing that?

    On my MacOS machine, VIPM can't find JKI VI Tester and all of the weblinks are vipm:// links and don't seem to work on MacOS. Is there a plan old download link for vi tester .vip file?

    Yes I can see the JKI packages. I noticed there appears to now be a "MacOS JKI VI Tester" package

    I understand cleaning up references is generally a good thing, but is there a reason the JKI State Machine attempts to close the This VI reference of a VI that is in memory? This in my mind is basically a no-op and can be removed because the close can't remove the VI from memory since that is the VI that is running. Which brings me to question why we even get a copy of the This VI reference and put it in the shift register. If you have a property or invoke node set to the VI Server class "VI" then you can leave the reference unwired and it assumes "This VI", which is actually seen in the "Initialize Core Data" case. Is there a good reason to keep a copy of This VI in the cluster? And if so is there a good reason to have a Close Reference in cleanup?

    I have a colleague that is interested in learning LabVIEW and I want to get him started on the JKI SM (and SMOs) right out of the gate. Are there any ready-made presentations that demonstrate the common pitfalls facing a new developer, and how the JKI SM handles them? Thank you, Jim

    Perfect Jim, thanks. I'll try the workaround and keep an eye out for the fix. I'm not permitted to follow that link, is the workaround the same as Jens Gräwe suggests here?: https://support.jki.net/hc/en-us/community/posts/360000027103-Error-in-Deactivation-Infos-in-VIPM-Pro Cheers, Steen

    Confirmed this error on LabVIEW 2017 (no SP1 yet), and VIPM 2017.0.0f1. I'll try it on LabVIEW 2017 SP1 in a few days.

    Hello JKI, I wanted to follow up on this issue as it seems that Deactivation still does not work when Binding a license in VIPM Pro. When a product uses this feature in VIPM, and a customer tries to deactivate, they are given an error "Unknown Error". This error is not given if a developer uses the "add-on Licensing Tool" inside LabVIEW and doesn't bind a license during build time. Here is how to reproduce the problem: Install TPLAT from VIPM: vipm://ni_lib_tplat License an LVLIB using TPLAT Standard Mode (Tools > Add-on Licensing Tool) Delete the licensed source code, but keep the .lf file that was created Create a VIPM build spec with the unlicensed lvlib Enable "Bind License to Library at Build Time" in "Licensing and Activation tab. Enable deactivation and use the credentials as described in your help document (http://jkisoft.com/vipm/docs/2014/index.html?turl=licensingactivation.htm) Build package Install Package on test machine Create a test license in SOLO server for the product Activate the product in LabVIEW with test license Deactivate the product in LabVIEW and receive an "UNKNOWN ERROR!" Has there been any investigation into this issue and is there any timeline for resolving it? Please let me know if you need any information from our side. Thanks for your help, David

    Note that if you do this you are committed to making sure that any sequence of “states” you call must be able to handle any possible external interruption at any point. In other words, you must be super vigilant against race conditions. With the “idle” method, one can choose where in a sequence of steps one will accept outside input. For example, if you had the macro: Take Data Analysis Data Save Analysis and also a “Set Parameter” event that changes a parameter used in Analysis and Save, then you have a race condition where the analysis may be saved with a different parameter value, if the “Set Parameter” happens between Analysis and Save.

    Hello, I've been trying to implement an application using the state machine template. Using Javier Ruiz's excellent webinar as a guide, I configured the template using a 9022 RT with a 9116 chassis. The FPGA code runs well but I get this message when executing the RT: Error 53 occurred at Property Node (arg 1) in RT Main.vi Possible reason(s): LabVIEW: Manager call not supported. I am using LV 2014sp1. I've tried this using the 9024 RT and a sbRIO9641 - both issue the same error. Any ideas as to my (obvious) incompetence? Thanks!
