Hi,
Is there any possibility to run SSR (attached data sheet) via LabVIEW?
I have got NI 9264and NI9265.

Record Data only Once a Day at 10hz
Hi,
I am running LabView 2011; I have a program where I will be running a test for 14 months. However; I would like to only record and write data once a day for 10 min at a rate of 10hz; the time during the day does not matter. I don't see any setting in the "write to file" function to do this. I cannot figure out how to do this; any help would be appreciated!

Mean with collector or Mean Ptbypt after true signal
Dear All
After searching in the forum, and after trying use the collector and the Mean PtByPt vi I still do not have what I need.
I will work with ni usb 6009 daq.
I need to acquire data after a true value (in my caso will be with a proximity switch) for an about 1 secound duration, no matter how much data acquires, at the final I need only the average value of all data collected during the true signal.
I try with continous samples and N samples but seems do nothing.
The collector should work, but it ask for the amount of data and it has bolean inputs for reset and for enable, but it gives data all time, even if i change the number of data collected...
If some body can help me with some tips I will appreciate.
best regards

NXG cannot get online help. NGX crushes by login.
Hello,
first I just tried to get online help in NXG 1.0. It tried to connect, but could not pass through our proxy. I canceled it several times. Now there is no reaction at all, if I click online help.
Then I tried to login (upper right corner of the window). The NXG crushes instantly.
I've sent a crash report either. Protocol-ID:ed34aad2-bd2c-4d3b-b00a-a4674b32ce18
The first idea is of course to uninstall and install again. But how could I then setup the proxy, so it doesn't happen again?

How to continuously read from scope and pass data to Matlab script?
Hi all,
I'm stuck at getting my code to continuously read data from Tektronix scope and pass the data to Matlab script so it can be processed. I like to read say 1 channel (V1) and pass this to Matlab for further processing. I have made a simpler code to show what I mean (screen shot below).

Difference between deploy and run on CRIO
I am using a CRIO-9073, I have it added to my project and executing code. I want to know what the difference is between hitting deploy and hitting the run button on the front panel? I know that when I hit the run button it updates the front panel and runs the VI as I would expect.
Is there a way to run the VI without that front panel being open? I assumed that's what the deploy option actually does. Am I correct with that assumption? If not, what is the difference?

Function generator - set frequency to AO
Hello.
I am trying to use attached example to add function generator to my AO.
My goal is to switch on/off AO with max 5Hz frequency - should I look for different solution for my problem (connect AO to DI, but I will still need generate function to add frequency to the signal).
I am using NI USB - 6009. I am receiving error 200077 (see attachment)
Thanks for any help.
Thanks,

Help: Stopping conditions while acquiring data on myDAQ
Hi,
I am reading the signal from a simple sensor using a myDAQ. All I want to do is stop the myDAQ from taking data once it exceeds a value such as when it reads an amplitude of 7 and if it never reads that number then to just continue until a user stops it. I don't know if this can be accomplished with just a While Loop and a true and false case or if I need an Event Structure. Either way I am lost.
Please help!

Learning to use two DAQ devices at same time; Please comment.
My reason for playing around with two DAQ's at one time is that I have an application that will require more than one daq. Because many I/O. So I just wanted to see if I could get two working. Please see my attached VI, and comment on it please. Is there a better way? have I used the right approach?
I'm using measurement computing's USB LS1208, two of them just for development purposes.
Thanks for your input in advance.
Mark.

Create a Project Template for LabVIEW NXG
Hello,
I have similar projects that can started from a template. I would like to create a template and instantiate the project from custom template. What is the procedure/process to create my own project template in LabVIEW NXG?.

Type Def'ed Cluster Appears Void?
I was working with some hardware abstracted classes, and building them into VIPM packages. The source was fine and the build seemed fine. Then I go to drop them on my palette and an array of a cluster appeared as if it was a broken wire...sorta. Just watch the video:
https://www.screencast.com/t/XwSaRtSFY
After that I closed and re opened LabVIEW and things were fine again so I believe it to be something I did during the video that forced a compile of that typed control which might have been the issue. Since then I haven't been able to reproduce this issue. Anyone seen this before? This is in 2017 SP1 F1 32-bit Windows 7 x64.

Serial coms lost after program re-start
Part of a program has to read a set of scales using serial coms and when first run it is fine. However if the program is stopped (controlled shut down) and then re-started it sometimes can no longer access the serial port and if the program is stopped message pops up to say that serial com port not available. The only way to get it released it is to close Labview down and then open it up again. I know this is an issue if the serial port is not closed down correctly but thought that I had taken care of it with 'Visa Close'. Could it be that the instrument is not allowing the port to close?? any thoughts would be appreciated,

Arduino Interface for LabVIEW "Stepper Write VI" Write in Half or Micro Steps
Hello everyone,
I am developing a LabVIEW code which uses the "Stepper Write VI" to control a stepper motor. I am simply curious if there is a way to use this VI to increment the motor in Half or Micro steps as opposed to full steps. If there is not a way to use this VI for that task, what would be another optimal method for controlling the motor with half or micro steps?
Thank you.

Converting an array of XYZ values to an RGB image
Hello!
I have a 2D array of XYZ values. I want to create a 2D image where the color of a pixel is a mapped value from the Z coordinate (a contour plot). Right now, I just have the Base Labview version, so I don't have any of the contour plot VI's. I do, however, have the intensity plot, but it's usually pretty blocky. The values I'm working with are as follows:
X: 0 to 20
Y: 0 to 100
Z: 0 to 1
Is it possible to either:
- Map out an image using the array to make a set of pixels to, then, create a bitmap?
- Space out the data better so the intensity graph isn't so blocky?
- Something else to create a 2D Contour plot from a list of XYZ coordinates?
Thanks,
Joe

Timeout structure for a function
Hi all,
I am using LabVIEW 8.5. In there, I call a function to query a database. The read takes 7seconds. The sql function does not have a timeout parameter.
I would like to create my own timeout structure such that after 1second, the program bails and returns an error log instead of hanging for 7 seconds.
Is there a way to do this in LabVIEW 8.5?

How to time a case structure?
hi,
I am using cDAQ 9191 along with module 9205 for data acquisition. Attached with the post is my Lv code foe data aqcuisition and saving it to a measurement file. It is working fine. I start with running the code and i can see the waveform of all my 9 channels. afterwards i can press record button to start recording the data and storing in TDMS file. everything is quite fine till this. Now i need to stop the recording after 6 seconds automatically( which i need to do manually at this stage-aborting execution or pressing stop button on front panel). I guess i need to "time" case structure containing "write to measurement file". But how to do it?
Can anyone help? Or any other solution , after looking into the attached code.I am new to LV. TQ
