Error 200380 occurred at DAQmx perform bridge offset nulling operation

I had a working VI that could balance a wheatstone half bridge and read and record measurements. My sensors are attached to a SCXI-1314 modle in a 1520 box in channel 0 (positioned as in the manual for half bridge) with the completion resistors in the appt places in ch7. It used 'custom voltage with excitation'.
Wanted to improve this VI so that it would also do a shunt calibration. I therefore connected the shunt resistor in the board over my active sensor as in the manual. I tried then to create a virtual channel for it - but it wouldn't work. So I gave up on that idea and tried to put things back how they were - deleted the virtual channel, and removed the connections to the shunt resistor. Except now none of my previously working VIs will work. I have built a new VI, and that can find a signal but not balance the bridge. I get:
error 200380 occurred at DAQmx perform bridge offset nulling operation.
I have checked the hardware again, and it's all wired correctly - it seems like the VI can see the channel but doesn't know what to do with it. Have running the VIs with and without a custom voltage with excitation channel created but nothing works.
Help!

Hi LucyWH
Have you tried re identifying the chassis in Measurement and
automation explorer?
Have you changed the jumpers at all as when rewiring this is easily
overlooked?
I have found some links that you may find useful:

Bridge Offset Nulling Doesn't Seem to Work With SCC-SG24

Does anyone know if the DAQmx "Perform Bridge Offset Nulling Calibration" vi works with the SCC-SG24 modules? We have used our NI-9237 module in the past to acquire dual-channel load cell (thrust & torque) measurements, and calling that vi does a fine job of zeroing out the values before applying the load. However, it doesn't seem to work when we try to take the same measurements using an SCC-SG24 module.
We are able to zero the values manually, by using the nulling resistors and potentiometers in the SCC-SG24. But, whether the nulling resistors are installed or not, we are not able to zero the values using the "Perform Bridge Offset Nulling Calibration" vi. Running that vi does induce a significant offset in the values, but it is not the correct offset needed to bring the values to zero. For example, with no load applied, a torque reading before running the vi may be +1090 in-lbs, and be "zeroed" to -465 in-lbs after running the vi. Running the vi multiple times (to check repeatability) always brings us back to approximately -465 in-lbs.
An additional issue (not sure if it's related or not) is that if we try to run this vi to offset just one of the channels in the task (such as just thrust, but not torque) it will still induce a small offset in the other channel, which doesn't seem right.
I guess I'm not clear on whether the subject vi is performing an operation on the hardware, the software, or both, so I'm not sure whether the SCC-SG24 modules may not be compatible with this vi?
Thanks for any help you can provide.

Hello Dhruser1,
I think that the DAQmx Perform Bridge Offset Nulling Calibration should work for the SCC-SG24 module. Take a look at this article: Removing Large Initial Offset for Load Cell or Strain Measurements with SCXI-1520 or PXI-4220 in particular it mentions that using this VI in addition to the auto zero can introduce an offset. If you're doing both these is likely the cause.
Also, when you specify specific channels using the channels input are you also setting the "skip unsupported channels to false? If not this may be why it affects other channels.
I hope this helps, and if not please feel free to post back with an update after trying these things.
Cheers,
Brooks

Error -200587 occurred at DAQmx Start Task.vi:7

I am running the attached code Merrit_Coil_calibration, and I get the following error:
Error -200587 occurred at DAQmx Start Task.vi:7
Possible reason(s):
Requested operation could not be performed, because the specified digital lines are either reserved or the device is not present in NI-DAQmx.
It is possible that these lines are reserved by another task, the device is being used through the Traditional NI-DAQ interface, or the device is being reset. You might also get the error if the specified resource is currently in use by LabVIEW network variables bound to the DAQ Channel, or if the DAQ Channel is being used in any OPC Client software.
If you are using these lines with another task, wait for the task to complete. If you are using the device through the Traditional NI-DAQ interface, and you want to use it with NI-DAQmx, reset (initialize) the device using the Traditional NI-DAQ interface. If you are resetting the device, wait for the reset to finish.
Device: Dev2
Task Name: _unnamedTask<F>
I am calling the same DAQ, many different places in my code and I think that is the problem, but I can not figure out why or hw to fix it. Anyone have any suggestions?

Thank you both for your input. I slightly changed my code to Merritt_Coil_calibration (updated code attached) and the first error went away, but now I have a different one which is:
Error -200429 occurred at DAQmx Write (Digital U32 1Chan 1Samp).vi:1
Possible reason(s):
Value passed to the Task/Channels In control is an empty string (or I/O control).
The value must refer to a valid task or valid channels.
As far as what DAQ device I am using, it is the NI USB 6009. I am only using digital port 0. During different pieces of my code I send different values to port 0. I am using this to drive some stepper motors. I thus send square waves on the different pins on port 0. I do not know if this is exactly what you were asking.
Whatever the case, I was wondering if anyone knows why this error occurs and how I could fix it.
thanks.

Hi,
I'm working with a ni-PCI 6251 card. I got the error : Error -229771 occurred at DAQmx Start Task. Possible reasons :Internal sofware error occured in MIG software ... when I'm trying to launch my data acquisition vi. This error was already reported in this post :

I tried to reinstall DAQmx as explained in the post but it unfurtunatly it did'nt fix my issue.
I've notice the following points :
1. This error appears randomly, after several reboots the vi will finally run without error
2. The error only appears when the vi is included in project
I will really appreciate any kind of help.

Error -200609 occurred at DAQmx Write: Selected Buffer Size Too Small

Hello, I'm writing some simple test VI's that I will eventually build upon to make an externally clocked analog output VI. I started with a very simple program to output finite samples using the onboard clock with the DAQmx Timing.VI. When I run the program, I almost immediately get an error. The error message is below.
Error -200609 occurred at DAQmx Write (Analog DBL 1Chan 1Samp).vi:1
Possible reason(s):
Generation cannot be started, because the selected buffer size is too small.
Increase the buffer size.
Conflicting Property
Property: Output.BufSize
Corresponding Value: 1
Minimum Supported Value: 2
Task Name: _unnamedTask<1C>
I have used DAQmx VI's before in similar applications and never encountered this error. Additionally, I read at the link below that DAQmx Timing.VI should be generating the buffer automatically. Any ideas as what could be causing this?
Specs:
Windows 7
Labview 2012

Below is a picture of my block diagram and the VI is attached.

Oops. Just realized my very silly mistake: I forgot to add the Start Task VI. I did so and it works as designed.

Error -200220 occurred at DAQmx Create Channel (CO-Pulse Generation-Time).vi:1

Hello,
Just a couple of days ago I was given a task to complete. To transfer a Labview program from a desktop computer to laptop.
The program itself uses a marlin camera to count the number of seeds.
The transfer was fine I installed Labview 8.2, installed the DAQmx drivers and labview vision.
I then transffered the program files over and ran the program on the laptop in labview and found an ERROR: Error -200220 occurred at DAQmx Create Channel (CO-Pulse Generation-Time).vi:1
I remember that the desktop had a kind of board attached to it: some NI board dont know the model etc.
can this be a problem? I have ensured that the problem is not the camera by checking it in MAX and it works fine.
When i do step by step debugging the problem comes to a VI that uses a palette called DAQmx trigger - data acquisition palette.
please see the attached picture!!
Is this VI the problem then and is this palette the main problem that is not enabling this program to work??
thankyou
p.s. Will it be necessary to use the NI board then? if so i dont think it will work on the laptop then as you will need to install the daq card
which can only be done on a desktop i think!!

Hello Rob W,
Yes I only use a Firewire to connect the camera.
And also i am sure that the device shows up in MAX under NI-DAQmx devices and not under Traditional DAQ. and it works under max.
I am sure the problem is as shown in the image. because i have not connected to the NI board on the laptop and the program is designed to work with the board.
but i have also tried removing the parts in the program that use the board but because of the complexity of the program i.e. wires i had some other problems i think
must be the wiring etc
thankyou

Error-50150 occured at DAQmx Write

Hello,
I am experiencing a seemingly random error in a large program. The error occurs in a part of the program that simulates tach signals to a CPLD. I have not been able to find out what conditions cause this error, it seems to be random in nature.
The full error reads this:
Error - 50150 occurred at DAQmx Write(Digital 1D U16 1Chan Nsamp).vi
Possible Reasons:
The software has entered an unknown state-usually as a result of a cascade failure induced by an unexpected series of state inputs. The operation could not be completed as specified and you should immediately terminate all further transactions if you are able to do so.
Task Name:TackABC_Write Port0 U16
The device we are using is a PCI-DIO-32HS, with Labview 7.1, NI-MAX 4.1, and DAQmx drivers 8.3.1. The task writes 3 signals to the CPLD, and it works most of the time, but every so often this error will occur. I was wondering what could be the cause of an error like this?
Thanks, Steve

Hello Brian, thanks for the response.
I made a mistake in my last post, it is actually a DAQmx clear task in place of the stop task vi i mentioned. When we first received this error it had no clear task at the end, but I added one. Even with this the error has still shown up from time to time. Would it help at all to add a reset device vi afte the clear task vi?
I took some screenshots for you as well. The first shot is of the function in question, the second is the same shot with the case turned to false, and the third is the inside of the main subvi. When the error occurs it focuses on the write vi that is inside the subvi. Let me know if there is more info I could grab that would make things mroe clear.
Thanks,
Steve

Error 200745 occured at DAQmx

Hello everyone.
Does anybody knows about this "error-200745 occured at DAQmx"
everytime I used 57.6KHz frequency and Initial delay of 1.
Looking forward of your help..
thanks and regards,
Ludz

Hi Ludz,
Do you get the error for every duty cycle? Do you know which frequency or frequency range the program will give you this error? What example program did you start with? One example you can try is the PWM-Counter Output.vi located in the example finder. You can find the example finder at Help>>Find Examples. When this opens, select the search tab in the top left and search for PWM. I would try running this example with the same settings as your other program to see if you see the same behavior.

Error -201003 occurred at DAQmx Create Channel (AI-Temperature-Thermocouple).vi:4

I get this error when using the NI USB-TC01 LabVIEW Temperature Logger and a J type thermocouple.
So I tried creating my own VI, the daq assistant gives me a correct reading but only for 1 sample. If I try to change to continous or N samples it will then give me this error:
Error -200077 occurred at DAQ
Assistant
Possible Reason(s):
Requested value
is not a supported value for this property. The property value may be invalid
because it conflicts with another property.
Property:
SampTimingType
Requested Value: Sample Clock
You Can Select:

What Is the problem?? I need to get a continous reading that I can use through a VI to get an excel file with the data. I also need it to be continous so I can manipulate the sampling rate.
By the way I also tried using the device on other computers and it still gives the same problem.

Thank you for your reply,
I am new to LabVIEW and I am not sure how to do what you explained. The DAQ assistant has a "number of samples" when you drag the bottom; is that where I need to create the loop??
What is the maximum # of samples per second that I can get with this device?? That is my ultimate goal with this experiment, to be able to get the most readings per second.

Error 6 occurred at RcvRespMsg - NI-488: I/O operation aborted.

Hi,
I am getting an error while trying to Read data bytes from a previously addressed device (RcvRespMsg) with Labview 7.1. In MAX I can write data to control my Test Receiver by GPIB USB-B. I tried to run the same software I usually work with and it was working totally fine until today. Since I didn’t change anything to the software, I wanted to know to solve that error:
Error 6 occurred at RcvRespMsg in ESVBv2.vi
Possible reason(s):
LabVIEW: Generic file I/O error.

Thanks a lot for your help,

Someone in the instrument control board will be more likely to know the answer to your question, so I would recommend posting your question there.

Cannot export from Lightroom 5.6 to jpg, Internal error has occurred, attempt to perform arithmetic on a nil value

Hi everybody,
I run Lightroom 5.6 on Windows 8.1. It's been a while since I exported anything and now I find that I cannot export to JPG.
I get an internal error, " attempt to perform arithmetic on a nil value" .
I remember that I used to have this situation before (different error) with previous versions. Than it was usually the "perform after export" that was without value.
However it is set ti " Do nothing" .
I've searched the web and found nothing. Anyone got an idea what the cause could be?
Thanks
Bob

Hi there,
so I found something! I was wondering why the "publish on harddrive" process did work, but the export to harddrive not.
So I looked in the difference of the presettings and found only the different options "choose export folder" and "predefined export folder" (don't know the exact translations, as I use the german version, but I hope you find what I mean.)
So I changed in the export settings the export folder to a fix predefined folder and there you are, export is working again!
Don't know the relation to the GPS-data, but anyhow.
Hope this helps to solve the problem?
Don't know if MS windows did an update which causes the error, but I didn't changed anything in lightroom as it worked before without these settings.
And of course in the long rund I would like to go back to the "choose folder" option, as I know have to copy the images to the right folder after export which is not a smooth process..
regards
_ulf

Error -200220 occurred at DAQmx Create Channel (AI-Voltage-Basic).vi

I am trying to set up my PMT using NI-DAQ 7.3 along with Labview 7.1. I keep getting an error message described above. I am new to this program, so I am not sure what is wrong. I have also received an error message stating the device could not be routed. Any ideas? Thanks

Hello WayneState,
Welcome to the NI Forums. The error message should say something like this "Possible reason(s): Measurements: Device identifier is invalid." This means that the name of your device was incorrect. You should use the drop down box to select the one is configured in Measurement and Automation Explorer (MAX).
There is very valuable information in this site since it is designed for people starting with data acquisition using our products.
Finally, I see you have other problems in this LabVIEW thread that suggest that you have already overcome the error in this Thread. If so, please post back your description of the resolution and if not, please feel free to post back some screenshots of MAX and LabVIEW.

Have you read the explanation for the error and did you verify the task or virtual channels exist?

Error in Error -200485 occurred at DAQmx Create Task.vi:2

I keep having this error:
The specified task cannot be loaded, because it is not in Data Neighborhood.
Check Data Neighborhood in MAX. Look for similar characters, such as the capital letter "O" and the number zero.
I would like to know what is the problem with the program. I've attached the VI.
Basically i am trying to control a physical LED connected to the NI Elvis II by comparing the inputs from DIO 0-7 and DIO 8-15.
So if DIO 0 is on, DIO 8 must also be on to turn on the LED.
But at the moment, the program cant run. Need help in spotting the mistake! >< Thanks!

From the code you attached I guess you haven't created a task (This is used to configure which is input and which is output) so you can take a look at the page how to create a task and go ahead.
Good luck
The best solution is the one you find it by yourself
