Currently, non default map constants (like the one shown below) are detected as fatal insanities when deploying to Real-Time targets and crash the LabVIEW development environment.
There is a workaround, which is to build the map from other data structure constants. The map constant above was built from the code below. However, it takes longer to execute, and it takes more code. That is okay in some cases, but it would be better if there was an option to simply use the map constant above.
When developing RT code (especially system upgrades) it would be truly helpful to have a virtual machine (VMware, MS Virtual PC, Sun Virtual box, etc....) that would allow us to run the actual VxWorks OS and LVRT in it's native environment, within the Windows OS. This would allow the code to run on the actual RTOS (I realize that determinism would be scacrificed) and provide the ability to actually test the functionality of the code in the actual environment to ensure that it runs as it should. It would also preclude the need to have a bunch of RT controllers sitting on the shelf in the event that you might need them.
There is and emulator for PDA module, why not for RT.
Could we have SSL on by default in the standard software sets for RT targets? It is not like there is much security in the default setup anyway, so having SSL active as well as the web interface with default passwords is just more practical (if that is the rationale for not having it on...(?)).
Background: Whenever I have loaded a default software package onto an RT target using NI MAX, I run into this little snag; I try to log onto it using SFTP or PuttY - only to rediscover that this is disabled. So then I have to go to the web interface or NI MAX to enable it. Most of the time we use RAD to replicate PACs anyway, but this is still another little thing we have to remember every time when dealing with the very first setup.
Currently, if you have hardware in a LabVIEW project (e.g. a cRIO controller, cRIO chassis, or R-Series PXI card), the only way that you can change this to another product is by adding a new one to the project and deleting the old one. It would be nice to be able to use a configuration window to change the model number of a piece of hardware to a different, but similar one. For example, if you have a 9072 in the project but wanted to change it to a 9073. Another example would be the ability to change, via menus, a PXI 7813R to a 7854R. Of course the user would have to update any code written to account for changes due to the new hardware. This is especially convenient when you are simulating and configuring test systems but aren't quite sure exactly what hardware you need. Currently, for each new piece of hardware (similar or not) you have to create a new device and copy all of the IO, VIs, libraries, etc. under the new device in the project.
With the linux-based cRIOs the console ("Write To Monitor" ; as intended before working with VxWorks/PharLaps OS) disappeared.
It's only possible to have strings pushed to the RS ports or in a (not managed) file.
As many cRIOs are connected to the network, it would be nice to have the "Write To Monitor" console access through Ethernet port.
The idea would be also to keep the global functionnalities of this console : see the strings in the cRIO webpage (of course), but also keep strings in a managed file (max number of logs in a file, ...) to have a 'buffered' access to strings sent to the console...
When working in the Windows development environment the application builder has the ability to implement a version number for the built executable. Additionally LabVIEW has the ability to querry this version number through a property node. I would like to see this feature carried over to RT systems as well. It would be very helpful in determining what particular build of the startup.rtexe file is running on the target.
Currently, you can view the console from MAX, but if you don't know what buttons to press... lets just say it's in there somewhere. My idea is to make it more accessible, such as a right mouse button feature off the RT Target.
I am often working with a compact RIO and I need to change the IP configuration or the software settings. Currently I have to open up MAX refresh my target list (which can sometime take a minute or two since we have so many targets). Then open up the RT target settings.
I think the IP address and software settings should be accessible from the project window by right-clicking on the target and selecting properties.
The MAX settings page could be reproduced in the general settings section that all ready has a limited ability to edit the IP.
You could also add a software category, so you could update the version of RIO or install scan engine.
If you get errors when deploying your real-time VI, you have to scroll through a small window and many many lines of messages to find the error that's in bold text... often only to find that it's just the "startup application is missing" error. It would be better to have a separate box where the errors are summarized for you.
When running a VI in development mode while targeting an RT device, you must "Save All" prior to deployment. This is annoying, especially when using SCC. I'm sure that SourceOnly will minimize this effect in LV2010, but the concept still remains: I don't want to be forced to Save All when I don't want my edits (or automatic linking edits) to persist.
When I choose to "Stop waiting and disconnect" from an RT system that is unresponsive, suppress the dialog box that fires immediately afterward saying that the connection has been lost.....I already know that, I am the one who asked for the disconnection.
Sometimes, you really just want a RT front panel. Of course, there is no real front panel, but when you run in interactive mode Labview is automatically setting up network communication to pull data from the RT target and push data to the RT target. Wouldn't it be great if you could just convert that whole front panel into a basic host VI? Right now, you have to manually convert all controls and indicators to shared variables. Granted, this does force you to be very careful about limiting the number of network-shared items that you have, but sometimes you really just want to run the VI in interactive mode...but deployed.
Or, better than that, convert everything into a web service and automatically build a silverlight UI (using Web UI Builder) which is hosted on the cRIO. Anything that provides you with a quick and easy way to convert from the rt debugging UI to a basic host VI would be great.
Wouldn't it be nice to have a native LabVIEW XML parser available on real-time targets? Storing your config data in XML rather than in Config-ini files is more flexible, techniques like XMLRPC would be easier to implement etc. Yes I know about the third party EasyXML library, but I don't want to spend extra money as we are already paying for LabVIEW 😉
It would be very convenient if we could format and install the OS/RTE on a target directly from the project window.
Currently, if I'm about to deploy a new application I typically format the target, install the OS software on it, then I deploy the application onto it...and finally I make an image of it that will serve as a way for others to deploy the application to production targets.
This involves use of NI MAX (format and install OS), LabVIEW (deply app) and RAD (make image). Doing all these operations (image-making as well would be great) from LabVIEW would make the workflow much nicer.
PS. In the project window today you have Utilities>>System Manager. The described operations should be available directly from the menu, but it would also feel natural to have these options from the system manager.
