Allow the deploy libraries method to work in RT OS

Status: New Submitted by Active Participant on 02-10-2010 09:49 AM 4 Comment

It would allow an RT executable to deploy shared variable automatically

(and not from the project explorer or the host computer as mentionned here)

Allow Dynamically Launched VIs to be marked as "Always Deploy"

Status: New Submitted by Member on 01-23-2012 03:05 PM 1 Comment

At the moment, there is a small development problem with dynamically launched VIs (via the Asynchronous Call method). They are not recognised as dependencies during the deployment process, so the code can't be run effectively in development mode via the run arrow (those VI's will return File Not Found errors).


A simple fix for this would be to be able to mark VI's as "always deploy" in the project window.

SDXC card support for cRIO 9031 Linux Real Time

Status: New Submitted by Member on 06-25-2015 08:09 AM 2 Comment

The cRIO9031 with Linux Real Time did not support SDXC cards. Only SDGC with a maximum of 32GB supported by cRIO.

For logging application their is a need for more than 32GB => use of SDXC cards with 128/256 GB

Connect to FTP server option under Utilities

Status: New Submitted by Active Participant on 07-18-2011 08:05 AM 1 Comment

If you right-click on the RT target in the project and select Utilities you can:

 

-View in system manager

-View in browser

-etc...

 

It would be useful to have a View in FTP Client there as well. I seldom need to access the web interface, but I often want to delete files prior to a new deployment e.g. and this would be a quick way to do it.

 

Yes, you can use the web interface to access the files as well, but that's much more cumbersome than to just open an ftp connection.

Generate warnings in case of property node usage, during a RT application build !

Status: Duplicate Submitted by Active Participant on 12-08-2012 09:55 AM 2 Comment

Hello,

 

I have recently to work with a RT application.

 

In this application, i used a property node in order to get all values of an ENUM.

 

 

=> This feature works fine when you debug your application using LabVIEW on the host ! Smiley Wink

 

=> But the same code doesn't work in real RT execution. Smiley Sad

 

I know very well that some property nodes doesn't work in RT programming, but when you have to go from windows application, to FPGA, to Crio, ... you often forgot this point ! LabVIEW should help us to limit this kind of mistakes !

 

It would be nice, if LabVIEW could break RT VI's, or generate a list of warning during RT application build, when an application is using non RT compatible property nodes !

 

It would be nice to get this warning during the compilation time, and not only at runtime ! 

It would also be nice, if the LabView RT debug tool could generates the same errors than a real RT target.

 

Thanks for help.

Include (remote) embedded GUI on all LinuxRT targets

Status: In Development Submitted by Active Participant on 01-07-2015 06:46 AM 2 Comment

The new embedded GUI option on the new LinuxRT based cRIOs is great. It would

 

a) be nice to be able to access it remotely, and

b) with remote access *all* LinuxRT targets could support it, even the ones without a display port...I would love to use that on our new sbRIO-9651 instead of going back typing in the Bash shell...

c) Perhaps the GUI could even be embedded into the web interface as well 😮

LabVIEW RT - Improved Debug Output

Status: New Submitted by Member on 12-01-2011 09:21 AM Comment

It would be nice if LabVIEW RT could give more output during the startup process of a LabVIEW real-time executable. For example if the rtexe is started at all or not, if there are missing dependencies during the loading process or other usable stats.

 

In my case I had problems with the German codepage. The build process was done without failure. But the rtexe didn’t start at all. I used special German characters like “öäü” in some VI names. And the rtexe couldn’t be loaded for that reason. But I didn’t get any message.

 

So please improve the debug output for LabVIEW RT.

Provide a method for RT code to determine the name of its Project (such as a Property Node)

Status: New Submitted by Knight of NI Knight of NI on 06-17-2013 08:23 PM Comment

At any one time, we have several complex LabVIEW-RT projects that run behavior experiments for us, taking multiple channels of analog and digital data while providing a complex series of audio and visual stimuli.  For each project, there is an RT part that "runs" the Experiment and a tailored Host part that runs the UI, handles an Excel Workbook that specifies the various trials being performed, displays the data, and saves the sampled results to disk.

 

Each of these projects are developed using LabVIEW Project, and each LV Project has its own, unique name.  When we build UI and RT executables, we would like an "automatic" way to associate them with each other.  A "natural" way would be to use the "shared" information of their joint Project.  There are ways to get the Project name in the Host UI code, both in Development mode and from an Executable.

 

I would like to propose that NI provide a Property or something similar for the RT side so that the RT code, at Run Time, could determine the Project from which it came.  With both sets of code knowing their shared "ancestor", they could use this information to ensure they are talking to their proper counterpart.  They could also use it to "mark" data structures (such as Files or Folders) that belong to them.  For example, there could be multiple configuration files, one for each Project, but they could be uniquely identified as "<Project> Config.xml" (where "<Project>" is the name of the Project containing the VI, allowing the appropriate Configuration file to unambiguously be chosen at Run Time).

Shared variable export to .csv should work with virtual folders

Status: New Submitted by Member on 09-21-2011 01:52 AM Comment

If I have variable library with virtual folders and I choose "Export to..." only top level variables are exported to the file. I suppose that also variables inside virtual folders should be exported. I think virtual folders make structure clear and export/import is useful if you are working with several projects in different computers. I would like to see them work together.

Make it possible to select "Run as Startup" without having to build the app first.

Status: New Submitted by Active Participant on 07-18-2011 07:42 AM Comment

If you try to select "Run As Startup" before having built the application you are stopped by LabVIEW with the phrase "The Real-Time application has not been built.  You must build the application before deploying."

 

This is bad behaviour. Instead LabVIEW should silently do the requested task, including any prerequisite ones (the build), or at least offer me to grant it access to do so. The Run As Startup choice already includes the deployment option (no complaints from it if I have not done that yet), there is no reason why it could not do the build as well.

Filesystem Rights in Web-based configuration and monitoring

Status: New Submitted by Member on 11-22-2010 08:31 AM Comment

Hello,

 

it would be very nice if i could give users in the Web-based configuration more specialized filesystems rights.

In the moment i only can give the user the right to write on the whole filesystem or on nothing.

In my case i would like to sent our customers updates of the startup.exe, which they can install their self via ftp. Without them having access to everything on the filesystem.

Please vote if you would like to have this option,

Reconfiguration from console (mode)

Status: New Submitted by Active Participant on 04-12-2012 05:50 AM 4 Comment

The console mode of RT controllers has very limited functionality. It would be great if all or most of the settings of the controller were editable from the console.

 

File browsing and transfer, plus software loading, would be nice too. We have had cases where the controller is operational and holds valuable data, but because the network interface has gotten damaged we have had no way to extract that data...

Add maximum velocity and max. Acceleration/deceleration to SoftMotion axis property page

Status: New Submitted by Member on 03-22-2012 11:03 AM Comment

I think the configuration property pages for SoftMotion axes are missing the parameters for maximum velocity, maximum acceleration and deceleration for individual axes.

When performing single axes moves it is somehow easy to control these parameters because they are wired to the appropriate property nodes when configuring the move itself.

But when performing moves with axes in a coordinate space the move parameters given are for the resulting vector, resulting in unknown velocities for the individual axes.

 

When configuring the maximum velocity and acceleration/deceleration for an axis there should be the option to

a) Generate an error when the requested move can not be solved within the limits

b) Coerce the limiting value to its maximum and solve the move using the new values, generate a warning

Remove Ability to Add Invalid cRIO Controller / Chassis Combinations in the LabVIEW Project

Status: New Submitted by on 01-17-2012 12:22 PM Comment

Currently, when you add a new (not existing) cRIO controller and chassis to a LabVIEW project, there is no check as to whether this is a valid configuration or not. For example, you can successfully add a cRIO 9072 controller with a 9112 chassis to a project, even though the 9072 is a controller with an integrated chassis. I believe that the LabVIEW Project interface should notify the user (via dialog box) that this is not a valid configuration before they can add modules and start developing code to use an invalid configuration.

Have the ability to set the stop mode for a limit switch from within LabView for NiSoftmotion

Status: New Submitted by Member on 06-21-2011 09:26 AM Comment

I've been attempting to perform a relatively simple homing routine on a motion axis where there are two limit switches (forward and reverse) and a home switch located somewhere in the middle. The homing routine starts by advancing forward and if it does not see a home switch, it will continue in the forward direction until the forward limit switch is activated. At this point, the routine will reverse the direction of motion and continue searching for a home switch until it would eventually see it (thus it is guaranteed that the home switch is found.) Once the home switch is activated, the routine performs a fine tuning procedure by slowly backing away from the home switch (in the forward direction again) until it is no longer active.

 

When using a c-series servo interface module, there is a Stop Mode property that one can set for each limit switch to either stop immediately, decelerate or disable the drive (See fig. Axis Properties and Limit Stop Mode ). When the stop mode is set to Disable drive, the homing routine fails upon triggering a limit. 

 

There are property nodes available to read the stop mode however the nodes are read only. (see fig. PropertyNode)

It would be nice to have the ability to programatically change the stop mode depending on the motion being performed. Our application requires that the drives be disabled upon activation of any limit switch under regular motion. However, during a homing routine since the disable drive stop mode impedes the routine, it would be benefitial to be able to change the stop mode to decelerate for the duration of the homing routine, and then change it back to disable drive once homing is complete.

Extend RT Web-based configuration and monitoring features to other browser than the dismissing IE

Status: New Submitted by Member on 05-17-2022 03:01 AM 1 Comment

As MS windows plan to dismiss IE in the next years ,

 

It should be very useful to have the same  Web-based configuration and monitoring features to other browsers or App than IE

 

in order to have an easy controlled access to RT file system , RT external storage devices , Event log and so on also in pc without any NI software installed ( MAX , ecc ).

 

Alternative methods today are not as easy and all in one as IE.

Remote Panel update FP object properties on connection or change (for embedded UI PACs)

Status: New Submitted by Active Participant on 10-02-2019 08:53 PM Comment

cRIO with embedded UI enabled allows us RTEXE front panel interactivity, with the ability of front panel objects' properties being changed programmatically. However, when connected with PC via Remote Panel, only object values are updated, but not the objects property (for example: table headers string arrays). This could lead to miscommunication of information as the Front Panel from embedded UI differed from the Remote Panel. 

 

I was informed though, if we looped the write property node continuously, the property can be updated from the Remote Panel end. This, however is counter-intuitive as we usually initialize the GUI objects programmatically once at the beginning (or if necessary due to change) and not continuously. Nevertheless, if Remote Panel can update the front panel objects during first launch and property change, similar to "Is Value Changed.vim", that would be great feature to have.

Add the Network Variable Engine Installer as a part of the NI CompactRIO Driver software

Status: New Submitted by Member on 05-19-2016 11:03 AM 3 Comment

The RAD tool is not a perfect fit for all cRIO deployments.  If you are unable to use the RAD utility to deploy a new version of drivers to the cRIO the process to get the Network Variable Engine onto the cRIO goes something like this:  Install LabVIEW and LabVIEW Real-Time, install NI CompactRIO drivers, install NVE and other driver software to the cRIO and then uninstall the LabVIEW components from the host PC.  This assumes that an executable will be installed to the host computer as the UI to the cRIO.  Seems like a lot of work for something most people would be using on the majority of cRIO deployments and might assume is a part of the CompactRIO drivers.

 

At the very least it would be great if the documentation found on the website were explicit as to what software needs to be installed for each of the install options available to install on to the cRIO.

It seems making plugins to Visual Studio has been abandon but it wouldnt matter if we were able to use a modern and full featured IDE.  Use eclipse as a base IDE and develop features on top of it including the ability to downlod and execute code to real time targets.  Developing an IDE based on eclipse isnt unhead of this is vxworks does with wind river workbench.
