Problems in creating channels (ni 6115)

Hi all,
I have used so far the Data acquisition toolbox in Matlab to operate with my NI 6115 card. Everything works fine. Now I would like to use
NI-DAQmx functions to control the card. I'm pretty stuck with some basics and hopefully I can get some help. I cannot perform 'DAQmxCreateAIVoltageChan' without errors. My code starts as follows:
%loading library
if ~libisloaded('nicaiu')
    hfile = ['C:\Program Files\National Instruments\NI-DAQ\DAQmx ANSI C Dev\include\NIDAQmx.h'];
    funclist=loadlibrary('nicaiu.dll', hfile, 'mfilename', 'mxproto')
end
% Defining task
DAQmx_Val_Volts= 10348; % measure volts
% Creating task
taskh1=uint32(1);
[a,b,taskh1] = calllib('nicaiu','DAQmxCreateTask','master',taskh1)
% Defining channel
numofchans = 8;
taskchans1=['Dev2/ai0:' num2str(numofchans-1)];
[a,b,c,d] = calllib('nicaiu','DAQmxCreateAIVoltageChan',uint32(taskh1),taskchans1,'',-1,-10,10,DAQmx_Val_Volts,'')
The task is appropriately created but once I define the channels I get
>> a = -200088
>> b = 1844396652
>> c = Dev2/ai0:7
>> d =    ''
What could be the problem?
Thank you!
Joonas

I have the same problem. I've tried a variety of pointers for the taskHandle, to no avail. I'm running R2009b 32-bit on Windows 7.
DAQmx_Val_ChanPerLine = 0;
taskhDO0 = [0];
[err,b,taskhDO0] = calllib('nidaqmx','DAQmxCreateTask','DO2',uint32(taskhDO0)) % err = 0
[err,b,c,d] = calllib('nidaqmx','DAQmxCreateDOChan',uint32(taskhDO0),'Dev1/port0/line0','',DAQmx_Val_ChanPerLine) % err = -200088
% setup MUX scanning task
charBuffer = '111111111111111111111111111111111111111111111111111111111111111111111';
muxHandle = libpointer('voidPtr',[0]);
muxHandle = uint32(1);
[result, ~, muxHandle] = calllib('nidaqmx','DAQmxCreateTask','aas2',muxHandle);
decodeDAQError(result); % result = 0
[result, ~, ~] = calllib('nidaqmx','DAQmxGetTaskName',uint32(muxHandle),charBuffer,length(charBuffer));
decodeDAQError(result); % result = -200088
[result,~,~,~] = calllib('nidaqmx','DAQmxCreateDOChan',uint32(muxHandle),'/Moo/port0/line0:3','MUXlines',0);
decodeDAQError(result); % result = -200088

Problem in creating new communication channel template in IR

Hi experts,
I currently have problems with creating new communication channel template in Integration Repository. If I choose the New-Context (Adapter Objects-->Communication Channel Template) the dialog "CREATE OBJECT" is shown. After I have inserted the Name of my template I push the create button.
Then the following error occurs:
STOP: Internal error: Object cannot be changed in display mode
DETAILS: Internal error: Object cannot be changed in display mode(CANT_SET_MODIFIED).
So can anybody help me. Thanks for your help.
Best regards.
Mario

Hi Mario,
            This is genral problem appearing in PI 7.0 with SP12.
            Previously, i have the same problem.
            i.e STOP: Internal error: Object cannot be changed in display mode
DETAILS: Internal error: Object cannot be changed in display mode(CANT_SET_MODIFIED)
            Regarding this we raise an OSS note SAP people.
            they gave the suggestion that update with SP13.
          i discuss with basis team and install the SP13.
           now the problem is solved, i can able to create the Communication Channel Template.
Please award points, if it really help to u

Problem when creating Database (Database, OS and hardware Configuraiton included)

Problem when creating Database:
Below are the problems, which I faced during creation of database. I have mentioned both the problem separately. Plus the log file maintained by Oracle during installation. It might help in diagnosing the error. Plus a little conclusion with I turned up to.
There are two problems, when creating database with Oracle Database Assistant. One when creating pre tuned database from CD. And second when creating customized database giving options your self.
Problem # 1:
When creating pre tuned database from CD. The process of creating Database is 90 % complete and is at step # 3 Initializing Database. It gives error ORA-03113: end-of-file on communication channel.
I searched following oracle help for this problem.
ORA-03113: end-of-file on communication channel
Cause: An unexpected end-of-file was processed on the communication channel. The problem could not be handled by the Net8, two-task software. This message could occur if the shadow two-task process associated with a Net8 connect has terminated abnormally, or if there is a physical failure of the interprocess communication vehicle, that is, the network or server machine went down.
Action: If this message occurs during a connection attempt, check the setup files for the appropriate Net8 driver and confirm Net8 software is correctly installed on the server. If the message occurs after a connection is well established, and the error is not due to a physical failure, check if a trace file was generated on the server at failure time. Existence of a trace file may suggest an Oracle internal error that requires the assistance of customer support.
Conclusion:
What I conceive from this problem and the help available is that, I have to install NET8 again. But I am not sure about the solution, please tell me whether I am rite or not.
Problem # 2:
When creating database with custom option. The process of creating Database is 2 % complete and is at step # 2 Creating Database Files. It gives error ORA-12571: TNS:packet writer failure.
I searched following oracle help for this problem.
ORA-12571: TNS:packet writer failure
Cause: An error occurred during a data send.
Action: Not normally visible to the user. For further details, turn on tracing and re-execute the operation. If error persists, contact Worldwide Customer Support.
Conclusion:
What I conceive from this problem and the help available is that, I have to install NET8 again. But I am not sure about the solution, please tell me whether I am rite or not.

Dont't worry about that. Before you
create a table(or view), it is wise to
drop the table(or view) with the same name.
If the name doesn't exist, of course there
is an error message. See the following script:
-------------------begin-----------
drop table students cascade constraints;
create table students (
sid varchar2(5),
fname varchar2(20),
lname varchar2(20) not null,
minit char,
primary key (sid));

Error Code -50150 from DAQmx Create Channel (AI-Voltage-Basic).vi

I have an executable, built from Labview 7.1 VI's. All it is doing is reading 6 voltages back from a 6008 USB-DAQ, and reporting the results back. Occasionally, it is throwing an Error -50150 from DAQmx Create Channel (AI-Voltage-Basic).vi. The full error message is:
Error Code: -50150
DAQmx Create Channel (AI-Voltage-Basic).vi<append>
<B>Task Name: </B>_unnamedTask<0>
Can anyone shed some light on this problem?
Cheers.

Hi fellas,
I have a really similar problem to the one Neilelph had, but I can´t see how to solve it from your answers. I attached a picture of my main .VI.
It´s basically a photodiode measurment system working as follows:
1. First the moving stages for the system get ready (X-Y moving stages for the Photodiode and Z stage for the Laser). That´s the CONFIG subVI in the left.
2. Then there is a For Loop, that repeats N times depending on the Initial Z, final Z and step values. So in this .VI the laser moving stage is the only one changing.
3. In each loop, the stages go to the X,Y,Z(t) posiition (MOV subVI), wait for the movement (WAIT subVI) and read the position. After that, the DAQmx acquistion part starts. I just sample the output DC voltage coming from the Photodiode (Dev1/ao1), 1000 samples in 1 second, and then I make an average of all of them with the Basic DC/rms block. So at the end I have 1 position of Z and one DC value. And it worked perfectly. At least for small number of iterations I have no problems.
The problem comes with small steps and a great number of iterations. For example last night I ran a measurement. 10000 iterations, the whole range of Z, and today i checked it. It worked fine until 5000 give or take, the half of the range. From that point, the DC ouput recorded in the .lvm file is just 0.00000. It´s the second time it happens, so I´m wondering what´s wrong because I´m affraid to make more long measurments and obtain the same results.
The error message I obtained is the same than in the thread title: -50150 DAQmx Create Channel (AI-Voltage-Basic).vi:6<append> <B>Task Name: </B>_unnamedTask<53BC>
Maybe it would be useful to mention that, sometimes, there is no error and I have some DC Output Voltage value, for random Z potitions, but since the first error message, that barely happens. The output is almost always 0.
Sorry for my writting skills in English. I hope you can understand my situation.
Thank you in advance.
Kind regards,
frilance.

Problem in creating Inquiry

Hello Experts,
i am facing problem in creating inquiry. Using transaction va11 i am creating inquiry.
inquiry type i selected ZGIN. when i create inquiry its asking me for sales order no
whether we need to give sales order no while creating inquiry.
Thanks in adavnce.
Sai

Hi Sainath,
For creating an Inquiry giving Inquiry document type is mandatory. In the T.code VA11 you have to enter the details lik Inquiry doc type, Sales Org, Distribution Channel and Division to create an Inquiry.
Normally the business cycle will be like this Inquiry->Quatation>Sales Order>Delivery---->Billing
So we can create a Sales order with or without refering to any existing Inquiry or Qutation. Where as Inquiry is concerned we need not to give any reference of an existing order.
Try creating an Inquiry w/o giving any order reference using the transaction VA11. If it is allowing to create,it is fine. Otherewise in VOV8, in the Inquiry document type control data, remove the settings "Reference mandatory" and try creating the Inquiry.
Regards,

Speed up time of AI Create Channel.vi task containing thousands of channels

I am creating an AI task containing a total of 8000 channels of different channels with each channel being acquired many times before the next channel is acquired. The channel list is something like 0,0,0,...,1,1,1,...,2,2,2...3,3,3... where each channel number would be acquired 2000 times. The purpose is to perform averaging. I am seeing that DAQmx Create Channel.vi takes about 100 msec to create 1000 channels for a total of 800 msec to create all channels (DAQmx 9.4, LV 11, WIN 7, CoreDuo P8700 2.5 GHz). I would like to speed this up by a factor of 10 if possible. Test vi attached.

Create Multiple Channels duration.vi ‏17 KB

Hi SteveP,
The DAQmx task contains data structures representing channels, which in turn contain other data structures representing channel properties and such. Most of the execution time of DAQmx Create Channel is spent allocating and initializing these data structures. They are separate from the task's input buffer (where data is stored until DAQmx Read is called). The input buffer is allocated when you reserve the task (which is normally done by DAQmx Start Task), and it is indeed allocated as a single large array.
DAQmx support for repeated channels focused on the SCXI use case, where hundreds of milliseconds of channel creation time seemed to be an acceptable tradeoff for measuring thousands of thermocouples. During development of NI-DAQmx 7.0, we used 3072 channels as our large system benchmark for channel creation, since that's the maximum number of channels supported by an SCXI task: 8 chassis x 12 modules x 32 channels (ignoring CJC channels). Repeated channels also make your use case possible, but this wasn't the original goal, otherwise we would have tried to make it easier to use for this purpose.
When replying to your previous thread on this topic (DAQmx AI Task with many samples CH0, then many CH2, then many CH3), I assumed that you were doing this because you were having problems when you took the straightforward approach to averaging, but Ben is right to point out that there are ways to deal with ghosting, cross talk, etc. What is the source impedance of the signals that you are measuring? How Do I Eliminate Ghosting From My Measurements? lists some options for dealing with high source impedance.
Failing that, is it possible for you to reduce the frequency at which your program creates and destroys tasks? If you can extend the task lifetime by reusing the same task more than once, you can avoid the channel creation overhead, or at least amortize it over the lifetime of the task. Note that you don't have to clear one task before you create a second one; you only have to make sure that two tasks don't have the same hardware reserved at the same time--if you do, you will get a reservation error. In most cases, stopping the first task before starting the second is sufficient to avoid this. It is possible to create multiple tasks up front, then switch between them throughout the rest of your program.

Using two daqmx create channel to acquire signals in random

Hi
I am trying to acquire signals from PXI 4472 with two DAQmx create channels. The channel selection is random. For eg. first create channel i have ch. 0, 2, 4, and 6 and the other create channel is Ch. 1,3,5 and 7. This I can do, but the problem is that I need to write the acquired data in seperate files for each channels and that too in sequential order. How can I do that. I know i need to use the loop but how will I will select the channels from two different task.
Thanx in advance
Nitin

Ok, here was my idea, I am not sure if it will work for you or not after looking at your VI.
You can use some of your subVIS that you made to make the path different for each file. But what I had in mind for the channels was what I did in the vi i attached. You can just repeat the process for each of the channels and you would know that they were saved correctly. You could also feed in the iteration number of the main VI while loop to have the binary files change sequentially (ie, data1, data2, etc).
Again, this may not be a route you want to take, you may have other ideas.
Ill try to work on it some more later, but I have to get back to work for now

DAQmx- create channel- no channels found

Hello,
i am new to labview. So maybe my question is easy...
I want to generate a signal. That's why i am using the DAQmx-create channel.vi . I i created a control to chose the channel, where the signal is generated. But no channels are found.
i am using PXI 5412 and my device is visible in MAX. So i don't know what is the problem. Can anyone help me?
Thanks,
Ratta
Solved!
Go to Solution.

The 5412 is an Arbitrary Waveform Generator. It does not use DAQmx. It uses NI-FGEN.

Problem in creating DLL for a LabVIEW VI

Hi
I am facing problems in creating DLL for a LabVIEW VI. Previously i had no problems in creating DLL for the VI that transmits a message from serial port to NI - PXI 7831-R Reconfigurable I/O card (configured by FPGA MOdule). When i try the same VI with a customized port developed using IVI drivers i am not able to create the DLL. It gives me error as follows:
Fatal Internal error: "datamgr.cpp", Line No: 1882
Please somebody help me out to fix this error.
Regards,
Subramania Bharathi

Hi,
Thanks for your curiosity in replying my questions. I am really sorry for replying so late. Actually the problem was with the NI SWITCH 2503 functions. Actually i was multiplexing the channels of my customized serial port using NI Switch module. This switching is done before i start my communication. My VI follows a sequence as follows.
1. Connect two channelss using Switch functions
2. configuration of both FPGA and the customized port
3. Transmit data from the port
4. Receive it in FPGA.
5. Reset the channels using Switch functions
I never expected that the error was because of NI Switch. When i removed them from my VI i was able to create the DLL and able to create sequence successfully to run in the Testsand. And
further i am using Switch Executive for swithcing the channels in TestStand.
But now i am very curious why it posted me that error when i used my NI Switch function?? I tried to create DLL for a VI that switches two channels and i was successful. But the error occurs only when i combine i with my FPGA functions!! If you could trace out the reason, please let me know
Once again thanks a lot for your support

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

Creating two channels with two "daqmx create channel.vi"

Hey guys,
I'm perform some piezo measurements and my program has one channel for the input (signal that excites the piezo) and one channel por the output (piezo's response).
Since the amplitude of the piezo's reponse varies a lot, my program adjusts the range of the acquisition changing the "minimum value" and "maximum value" properties in the " daqmx create channel.vi". Such an adjustment makes no sense in the input channel once the excitation has constant amplitude.
That is why I need to use two "create channel.vi". I could create the two channels with a single VI but if I did so, I would not be able to adjust the "maximum/minumum value" of only one of them.
The problem is: Labview always returns the error 50103: The specified resource is reserved.
Below, we have a screenshot of this part.
I tried also to add one "daqmx timing.vi" and one "start task.vi" for each of the "create channel.vi" and synchronize everything via error cluster but it returned the same problem.
The program itself is also attached but I don't think it will be useful.
Please, help me guys!
Regards,
Lucas

Hi,
    I have seen several discussion regarding this topic, however it seems that none of the solutions are working for me. Here is my situation, i am using LabView 7.1 which I use to generate my .EXE, when I generate my .EXE I use the Tab Intaller Settings to generate the Setup.msi. I then take the folder which contains the .EXE and the installer and bring it over to another machine which is running VM Ware with a freshly installed windows XP. (to make sure nothing is on the machine and then i get surprise at the custormer's site)
   Once this was done, i would start by lauching the installer and then the .EXE the result was the following, I would get the following message:

then as suggested in other discussions of this forum I download (537MB) and installed
on the target machine (VM Ware) the nidaq710 which i downloaded from
http://digital.ni.com/softlib.nsf/websearch/C1F802E457EA042586256DD00001B0C9?opendocument&node=132070_US
This did solve some problems BUT I am still getting the following message when I launch the EXE
Missing subVI DAQmx Create AI Channel TEDS(sub).vi in VI DAQmx Create
Channel(TEDS-AI-Voltage-Basic).vi.
Thank you

Hi Maldini,
Thank you for posting to the NI forums. Is the VM Ware PC using the same operating system as the development PC? Also, are you using DAQmx 7.1 on the development computer, or are you using a more recent version? When distributing applications, the driver version on the deployment PCs must match the driver version of the development PC.
If this is already the case, then you shouldn’t be receiving any of these error messages. There are few things that may fix this problem.
Reinstall the DAQmx driver.
Perform a repair install the DAQmx driver on the deployment computer.
Upgrade the DAQmx driver on both the development and the deployment PCs.
With Windows XP and LabVIEW 7.1, you are able to use the latest version of DAQmx, which is currently DAQmx 8.5.
After going through these steps, please post back if you continue to have problems.
