What are my options for deploying DAQ assistant with a built LabView application.

I am currently working on a LabView application which I intend to build with LabView Application Builder and deploy on a couple of computers within the company.  The application's end-users will need to create and edit DAQmx scales and virtual channels using the DAQ assistant once the application is deployed.  It looks like we (or anybody else) is only licensed use use the DAQ assistant to create scales and virtual channels if there is also a valid license for LabView, LabWindows, or Measurement Studio also installed on the computer.
(See <a href="http://digital.ni.com/public.nsf/allkb/402D2EB45062FBC486256DD600634695" target="_blank">http://digital.ni.com/public.nsf/allkb/402D2EB45062FBC486256DD600634695</a>&nbsp;for the licensing restrictions message that pops up if you create a scale without having LabView, LabWindows, or Measurement Studio installed.) 
Is there an option to buy/obtain a deployment license which would allow my end-users to use the DAQ assistant without purchasing a LabView, LabWindows, or Measurement Studio development system license which they would not otherwise need or use?

That link does not apply at all. The link was referring to using the DAQ Assistant with an evaluation (unlicensed) version of LabVIEW. As a matter of fact, you cannot use the DAQ Assistant at all with a built application. The only way to start up the DAQ Assistant is to do so from the block diagram and you don't have a block diagram in an exe.
You can skip the DAQ Assistant altogether and use the low level DAQmx functions and with front panel controls, modify any aspect of task that you want. You will also install DAQmx and you have the option of installing MAX on the pc. Tasks can be added/modified there.

I get the same message as shown in that KB article if I start MAX and then attempt to create a DAQmx Scale without having LabView installed on the computer.&nbsp; I would prefer to do what you suggest (Install MAX and allow the user to create/edit scales and virtual channels using DAQ Assistant within MAX), but it doesn't appear the license for DAQ Assistant and/or NI-DAQmx will allow the end-user to do so without also installing a&nbsp;LabView, LabWindows, or MeasurementStudio development system.
What I'd really like to know is if there is a deployment licence I can purchase, or otherwise (legally) obtain, to allow the end-user to use DAQ Assistant within MAX without purchasing an otherwise unneeded LabView, LabWindows, or MeasurementStudio development system license.

I'm not sure what exactly might be happening on your system. I can create/modify a task on a pc without LabVIEW being installed. In any case, I never use the DAQ Assistant and I know that channels/scales/ranges can be changed in a built program using the low level DAQmx functions and only DAQmx and the LabVIEW run-time installed.

Hello, Dennis is right.&nbsp; The NI-DAQmx drivers themselves do not need to be licensed, so as long as they are there, you will have access to Measurement &amp; Automation Explorer (MAX) and be able to edit tasks.&nbsp; The low-level VIs (you can see them used in the LabVIEW shipping examples) are the ones you should use.&nbsp;

Thanks, everybody, for your quick responses.&nbsp; I probably wasn't clear enough in my original question.


I know I can use the low-level VI's to create and modify scales, tasks, etc. programmatically.&nbsp; However, what I want to do is let my&nbsp;users&nbsp;create their own custom scales (for&nbsp;a new sensor, for example)&nbsp;through NI-MAX.&nbsp; According to the message that pops up when I&nbsp;begin to create a custom scale in NI-MAX on a system without LabView installed,&nbsp;I'm&nbsp;only allowed to create scales, tasks, and channels if&nbsp;I have&nbsp;a properly-licensed development system installed (LabView, LabWindows, or MeasurementStudio) on that computer.


What I want to know is if there is a deployment license, or similar,&nbsp;available that would let my users create scales in NI-MAX, without violating the license terms, on a computer that has my built application, but no development system, installed.

Hello Mark, I have been able to successfully create tasks, scales, and associate
custom scales to tasks in MAX on a system without any of the
development environments.&nbsp; 
NI-MAX is not activation-driven, and can be installed on a system without having any of the NI development environments.Can you step us through what you are doing?&nbsp; I am having trouble understanding when you are receiving this error as playing with MAX in the way you described should not cause that.Have you tried yet using the low level VIs?&nbsp; The low-level VIs we are speaking of are not for creating scales or modifying tasks.&nbsp; The low-level VIs are the basic DAQmx Read/Write, Timing, Start Task, Stop Task, etc.&nbsp; You do not need to use the DAQ Assistant at all, and instead you can creat the task in MAX itself and apply the custom scale from there.

First, I should mention that this is probably not specifically a LabView problem.&nbsp; I asked the question here because I want to find out how I can let my users create their own custom scales in NI-MAX for use with my built LabView application.&nbsp; Using the low-level VI's is no problem at all.&nbsp; In fact, in my LabView program, I build the task based on the physical channels and&nbsp;scales specified by the user.&nbsp; However, I need to allow the user to create their own custom scales after my built LabView program has been installed on the computer.

- Open NI-MAX on a computer doesn't have LabView installed.

- Expand the "Scales" item in the tree.

- Right-click on the "NI-DAQmx Scales" item and choose "Create New DAQmx Scale..." from the context menu.

- After choosing "Create New DAQmx Scale...", the a dialog box pops up (see attached image) informing me that I'm not allowed to create new scales unless I have a LabView, LabWindows, or MeasurementStudio installed.

- If I check the "I understand and will comply with the Licensing Restrictions" box, nothing prevents me from creating a new scale, but it appears that to do so would violate the license terms.

Hello Mark, Thank you for your reply.It seems that the message you are seeing is merely a message and not an error.&nbsp; Your users should be able to create and modify tasks easily even though they see the message.&nbsp; If it does not stop you from doing what you need, then I would not be worried about the message since you do have a LabVIEW license on the development system and shouldn't be concerned with violating any licenses.Take care!

Time in LabVIEW DAQ Assistant and Write LabVIEW file
Hello all, I would be extremely grateful for your assistance in helping me understand the timing in LabVIEW. Here are the details of the system. The data acquisition is done using&nbsp;a simple LabVIEW 8.2 based program consisting of a DAQ Assistant VI and a Write to Measurement File VI, which writes data in TDM format (binary with XML header). The hardware consists of a 1042Q chassis that contains 2 PXI-6133 cards. 16 transducers are connected to these 8 channel cards. The chassis is connected to a PC by means of MXI-4 fiber optic cable and a PCI-8336 card. &nbsp; I would like to sample all 16 channels simultaneously at 500 kS/s for 2 secs. or 1MS/s for 0.5 secs.

labview crashing when calling labview-built dll
Hello I need some help with regard to calling a LabVIEW-built DLL in LabVIEW.I have created a vi in LabVIEW. I made the DLL for this vi. I called this VI as a re-entrant in another vi.This vi(calling DLL) has been working fine till yesterday. Since yesterday, it started crashing LV.I need some help in this regard.I am attaching the screenshots of the Application Builder configuration window, the B.D of the vi using DLL and that of the configuration window which pops up when i call the DLL.I made a vi which performs FRA. I built its DLL.I have around 10 inputs. I output 3 one-dimensional arrays, and a string from the DLL.When i build the DLL, the builder defines the outputs 'gain', 'phase' and 'frequency' as arrays of 8-byte double.When i call this DLL in my vi, the configuration window sets them as 'numeric' outputs.Why does this happen? What is the solution to this?When i try to set them as 'array' in this configuration window, i get a warning that i am trying to change the data types which do not match with the data type found in the DLL. Is this the problem with my code or with the Application Builder?Now, after i change the 3 output datatypes to Arrays, and set their minimum length(i assumed that this value means the size of the array ), the vi runs and crashes LV. I am nto sure when it crashes, why it crashes. It runs fine at one time. It crashes at another time. I am nto sure if these arrays are teh reason why L...

Driver paths in Labview no DAQ Assist
Hello, I am new to LabView and I recently installed the student edittion of Labview 8.5. For some unknown, crazy reason i did not install this to the default drive path, ie C:program files\ etc but to another drive on the computer, ie E:.Now the problem is that i need to use the DAQ Assistant for my USB-6008 board. I have installed the the NI drivers which came with it and the board works fine in MAX, recognises it and i can get temp readings from the circuit i built. When I try to use Labview I cannot find the DAQ Assist in the Input section on the palette.Could some please help me. My mate gave me a file he did on his Labview but when i try to load it starts looking for DABmx Control Task and a whole host of other files.Much appreaciated for any help in this matter.Lee Hi Lee Its cool to install things into different places on your drive - sometimes its essential. there is also an easy solution to your problem. What you have at the moment is different drivers and programs spread around your computer with no links to each other so they are unable to reference each other. To create these links yopu will need to mass compile. Within LabVIEW go to the tools menu and then select Advanced&gt;&gt;Mass compile. This will bring up a window that will allow you to select a directory. Select the directory that you have saved all your DAQmx drivers and then select mass compile. This should allow you to see all the VIs in the correct menus within labVIEW. I hope this is of some ...

Using global variables between LabVIEW built applications
Hi, &nbsp; Firstly, Im sort of an idiot with this stuff, so please excuse my ignorance!!&nbsp; I am trying to develop a bunch of applications that communicate with a central VI through 2 global variables.&nbsp; Think of it as if I am transmitting messages back and forth, and one of those variables is for communication from any application to the central VI and the other variable is for communication the other way.&nbsp; As for the applications, any one of them (or multiples of them) can be open at any given time.&nbsp; So the end user has the ability to open one or two or more "panels" and they all work at the same time. &nbsp; Anyway, my problem lies in the use of the global variables.&nbsp; This whole system works great when I am using it in the labview development environment, but when I try to build applications out of my vi's, I have problems&nbsp; Its like each application has its own instance of the set of global variables, rathar than sharing them like they did in the Labview environment.&nbsp; So what this means is that only one application will work at a time, and when I try to use a second one at the same time, it wont "connect" to the globals. &nbsp; I have also tried implementing Network-published shared variables, which I think is the wrong way to go simply because of timing issues, and besides, I don't need to publish these things on our network. &nbsp; So is there any way that I can easily...

Re: LabVIEW and LabVIEW RT?
Hello Iman, I will try to illustrate it with an example since it all will depend on the type of application you would like to implement. Let's say you would like to implement an application where you log data, maybe exchange data with databases and you acquire a bunch of data points at a time not performing any type of control and where high determinism is&nbsp;not needed. In this case LabVIEW for Windows work great. If you on the other hand would like to implement a closed-loop application where you need high determinism and reliability and will acquire data point by point you would use LabVIEW RT which is an add-on to LabVIEW. I.e. you need LabVIEW + LabVIEW RT when developing an RT application. ...

why labview 8.51 change the variable name programatically and is there a better practice to create a driver for a modbus application using the DSC embeded driver in labview
first, let me give you a few backgound, im a developer (labview dsc) i work in the industry and im working in a project we choose labview because it works very ok with other application so we picked up for this one, the problem is that this application is this big: 150 variables per device 250 devices the variables include boolean, strings, double and some re-created variables, most of this must be historized, so the trouble i have is this one: first, when i create a new device, i use a library per device i used to copy the variables and create a new modbus driver for the device, inside the library, im using modbus tcp, so to do this faster i copy the variables and then in the variable editor i link it to the right library name, so this sound very good, obviously this sounds very easy, but well theres a think that i cannot escape, i always have to update the .vi with the new tags and it take a long time, but well thats my work, ok, well my problem begins when i return to my application with 4 devices and realize that it changes de variable path to another library i men it gave me the data of other device and not the right one, so thast the first one, and well in a stand alone app this could not be good, the second trouble i ve recently, ive add the 5, 6 devices, so the variable went down giving me bad values, i test it with kepware opc and it gave me the right values so its a labview problem, my question is: is there a reazon for this, what am i doing wrong? or whats the righ...
