• Error 200320: SCXI-1001 Chassis - Mod 1502

  Hello.

  I'll put a SCXI-1001 chassis with several modules, 3 of them 1502 with their 1314 terminal blocks for the first time. I used this chassis before reading temperatures and worked fine, so I'm sure that the problem is me.

  I get this error 200320 on simultaneous sample and hold trying to acquire data of deformation, but I think that the configuration is fine. I'm still fairly new to LabView and have tried to check the installation by the Express data acquisition module and MAX; but I get the same result.

  Please help me to implement as soon as possible, I need your knowledge.

  Thank you

• multiplexing of the strain gages with the scxi-1001

  I am trying to write a MatLab program that uses the C++ functions.  I managed in the collection of data of an extensometer, but I do not understand how to configure the multiplexing.

  I use a DAQ, SCXI-1600 in a SCXI-1001 chassis with 9 input modules 8 channel universal bridge SCXI-1520.

  I know that the hardware is possible to multiplex all 9 SCXI-1520 for the acquisition of data because we did it in LabView.  I have currently no LabView on my computer.

  My question is:

  How labview use C++ functions to implement this material to record 72 straingage channels.

  That's what my code looks like:

  Clear, clc
  rate = 100
  time = 1

  If ~ libisloaded ('myni')
  DISP ('Matlab: load nicaiu.dll')
  [notfound, warnings] = loadlibrary ("C:\WINDOWS\system32\nicaiu.dll",...)
  "C:\Program NIUninstaller Instruments\Shared\CVI\include\NIDAQmx.h",...
  'alias', "myni")
  end

  cards = 1
  Chans = 8
  taskh (1) = uint32 (1);

  % This is the C++ function called from MatLab-> int32 DAQmxCreateTask ('master', taskh (1))

  [a, b, taskh (1)] = calllib ('myni', 'DAQmxCreateTask', "master", taskh (1))

  chains of % for both channels 0 through 7 on each and SCXI-1520 cards.

  taskchans = {'SC1Mod3 / ai0:7 ',' SC1Mod4 / ai0:7'};

  samples = time * rate;

  chanName = ";
  minV = - 10F-4;
  Discharge = + 10-4;
  excitV = 3;
  gageFactor = 2.09;
  iniBrdgV = 0;
  nomGageR = 350;
  poissonR = 0.3;
  wireR = 0;
  scaleName = ";

  DAQmx_Val_Strain = 10299;
  10065 = DAQmx_Val_FromCustomScale;
  DAQmx_Val_QuarterBridgeI = 10271;
  DAQmx_Val_Internal = 10200;
  DAQmx_Val_Rising = 10280;
  DAQmx_Val_FiniteSamps = 10178;
  DAQmx_Val_GroupByScanNumber = 1;

  % creation of extensometer (virtual) channel

  [c] = calllib ('myni', 'DAQmxCreateAIStrainGageChan', taskh (1), tank (taskchans (i)),...)
  chanName, minV, discharge, DAQmx_Val_Strain, DAQmx_Val_QuarterBridgeI...
  DAQmx_Val_Internal, excitV, gageFactor, iniBrdgV, nomGageR, poissonR...
  wireR, scaleName);

  % set samplerate and number of samples
  for i = 1:cards
  [a, b] = calllib ('myni', 'DAQmxCfgSampClkTiming', taskh (i), cm, rate, DAQmx_Val_Rising,...)
  DAQmx_Val_FiniteSamps, samples)
  end
   
  Disable the trigger for the start of the %
  for i = 1:cards
  [a] = calllib ('myni', 'DAQmxDisableStartTrig', taskh (i))
  end

  % create variables to read data

  readarray1 = Ones (CARDS, Samples);
  readarray1_ptr = libpointer ('doublePtr', readarray1);
  arrayLength = samples;

  sampread = 0;
  sampread_ptr = libpointer ('int32Ptr', sampread);
  void = [];
  empty_ptr = libpointer ('uint32Ptr', Empty);

  Organization and reading raw data
  strain = ones (maps * chans + 1, samples);
  t = 0:1 / rate: time-1/rate;
  Strain(1,:) = t;)

  for i = 1:cards
  [readarray1, sampread, empty] = calllib ("myni', 'DAQmxReadAnalogF64', taskh (i),-1,-1,...)
  DAQmx_Val_GroupByScanNumber, readarray1_ptr, empty_ptr, sampread_ptr, arraylength);
     
  strain (chans * i-(chans-2): chans * i + 1, :) = readarray1;)
  end

  % Stop all tasks

  for i = 1:cards
  [a] = calllib ('myni', 'DAQmxStopTask', taskh (i));
  If a == 0
  fprintf (' slaughter task %s...) OK \n ", tank (j (i)));"
  on the other
  fprintf (' start task %s...) Failed \n ", tank (j (i)));"
  end
  end

  % Clear all tasks

  for i = 1:cards
  [a] = calllib ('myni', 'DAQmxClearTask', taskh (i));
  If a == 0
  fprintf (' task claire %s...) OK \n ", tank (j (i)));"
  on the other
  fprintf (' task claire %s...) Failed \n ", tank (j (i)));"
  end
  end

  It is the General form of my code.

  I tried to do one task per channel, but I can start only one task at a time.

  I tried to use DAQmxSwitchCreateScanList and DAQmxSwitchSetTopologyAndReset.

  -> but I don't know what the name of device for the switch.

  If anyone can explane how all these SCXI-1520 multiplex LabVIEW cards that would help a lot.

  Thank you.

  OK, I found the solution to this problem.

  The SCXI-1600 multiplexes based on which channels have set you up.  I simply add all 72 channels to the taskh (1) with the function DAQmxCreateAIStrainGageChan (...) then my samples are multiplied by the number of channels, I added.

• SCXI-1001/1102/1303

  I have trouble getting accurate readings of my components 1001/1102/1303 thermocouple.  I have 10 channels attached to the device.  All values are not accurate and are negative (in the-300-400 range.)  Moreover, when I unplug a thermocouple of its Panel, all 10 channels meet the entry as if they have all been affected.  I installed the equipment in the configuration of the plant with regard to polarization/pull-up resistance networks.  Can someone help me understand what I am doing wrong?

  
  

• How can I filter the noises of thermocouple using a TC-2095 and SCXI - 1102c?

  Hi all

  I currently have four TC - 2095 s connected to the SCXI - 1102c inside an SCXI-1001 chassis cards. These thermocouples are floating and I get a good amount of noise (400 Hz 3 phases and same 60 Hz noise) when we turn on some equipment such as fans, and fans. Using this current set up, how can I filter the noise? Or I would need to put in place a new hardware configuration (e.g., the SCXI-1102 cards)?

  Hi RALoo,

  The 1102 C has a lowpass filter with a cutoff at 10 kHz frequency, so you will not be able to filter into the material with your current configuration.

  Your first option is to use a software filter.  LabVIEW has several functions that do this. More information can be found here: http://zone.ni.com/reference/en-XX/help/371361J-01/lvanls/filter_vis/

  The second option would be to change to SCXI 1102 cards as you suggest.  The low-pass filter of the 1102 was a cut-off adjustable to 2 Hz frequency, which will stop the noise of 400 and 60 Hz don't affect your readings.

• get the MAX to recognize the SCXI modules

  Hello, try to keep it short, we strive for Labview 5.1 running on the XP machine, until we get new set kit to date in the future (current NT machines fail). I tried NiDAQ 7.1 8.1 drivers with a PCI-MIO-16-4th card in a Dell optiplex 755, and the current sticking point is to configure the system via MAX to specify the type of chassis and modules. Modules are not found automatically, and entered manually the results into the slots being declared empty, on a test of the chassis (chassis SCXI-1001). SCXI modules we are SCXI-1100, SCXI-1162HV, SCXI-1124 2 x and 2 x SCXI-1160. What should I do to make this work? Different driver? I'm not at all familiar with the inner workings of Labview!  Thank you.

  Rob,

  Thanks for the reply. The problem was more the cable SCSI detaches from the end of SCXI chassis (these connections seem very inclined to come drifting). The modules then self populated, and the system works now. The system worked very well for ten years, but the old Compaq PC fail now and we have only a few replacement Dell, but of course they come with Windows XP, while the ran Compaqs WinNT, it has so been interesting trying to get Labview 5.1 running on the new boxes with the old cards DAQ until we get funding for new cards / Labview 2010 / Teststand. Problem solved for now!

• DAQmx SCXI-1167

  Read more http://zone.ni.com/devzone/cda/tut/p/id/3308 he says rather non-challantly that ' module PXI-2567 and SCXI-1167 can also be programmed using the functions of NOR-DAQmx DIO. "

  Does that mean that what follows (simple example) would work with the SCXI-1167, installed in a SCXI-1001 chassis?

  

  What happens if the SCXI-1167 was connected to the PC via the USB-1600 module?  I'm inclined to think it WOULD because of the statement of the SCXI-1600 data sheet:

  "The SCXI-1600 is a module of control for entry SCXI analog, analog output, digital i/o modulesand switching and full 16-bit digitizer."

  Hello!

  Please post on the Forums OR! I have configured material today and succescully executed the code you posted. So, you're right, it's possible!

• Incorrect SCXI all the playback channels after running for more than 30 minutes

  I have a SCXI-1001 module. I use a thermocouple module (1102, breakout box 1300), input analog (off 2, map of 1100, 1300 in small groups), analog output (1124 map, 1325 breakout) and a relay (card 1160, breakout 1324). I'm using labview 2009. I created my channels manually to read all channels, I need about 1 task for entries of thermocouple and analog, 1 analog and 1 for task task for the output relay (total 3 tasks). Each task comes into contact with the SCXI area in a different section of a timed sequence. I read all my channels with precision for 30 minutes but then all of a sudden they stop reading accurately and all thermocouples read the same incorrect value as well as all analog input channels. I can't change the output channels either.

  The problem occurs more quickly if I increase the clock frequency. There are no errors showing when this problem occurs.

  What is an interaction of hardware failure or a software.

  Any help would be greatly appreciated. I also need to resolve this issue quickly because it is delaying the test.

  Thanks for your help

  Tim

  Thank you all for your response. I managed to solve the problem. It was a problem with the start of the task and to connect the clocks for different tasks. I've included only a single task to start my unstable code in the source code as for posed multiple startup tasks. However, I started my slave tasks (analog and digital outputs) before starting my master's work (analougue entered). This seems to have solved the problem. I intend to go more far by adding clocks at 2 slave atsks and linking them to the task of master.

  I used the sequence as part of documentation. Each links to sequence number to another sheet that I have has a flowchart to say what is each part. As you say there is no need to put in a sequence and do so limit labviews own data stream. I'll remove the sequences and put my documentation on the codes in the code directly because it is made in the examples of labview.

  Thank you for your help

Hi mz6yx6,

First of all, don't worry about trying to get to the ' devices OR-DAQmx "appear. 4.6 Max, which was first included with NOR-DAQmx 9.0, has a revised UI layout which displays the devices inside "Devices and Interfaces" rather than display them in subfolders like ' devices OR-DAQmx.

Also, thank you for the view a report of the configuration of the system MAX. The report shows that the SCXI chassis and modules are configured as simulated devices, which I think is the problem. DAQmx (> = 8.7) does not support configurations where a simulated SCXI chassis and modules are connected to a real communication hardware DAQ. Since your system has not simulated hardware DAQ (except the SCXI chassis and modules), the "Châssis Communicator" menu has no options to display.

To resolve this issue, remove the SCXI chassis in MAX and create a real one (not simulated). How to do this depends on if you manually configure the chassis or you import a configuration from a file .nce, .ini or .txt:

• Manual: right click on "Devices and Interfaces", then select «Create a new...» ». In the window "new...". "which appears, open the ' Chassis SCXI of NOR-DAQmx ' subtree and select the chassis type from there. Do not select "Simules NOR-DAQmx device" or modular Instrument The modules must be detected automatically, but you will need to manually reconfigure the accessories.
• Import from a file .nce, .ini or .txt: in the dialog box 'Assistant Import Configuration', check that the 'Warnings and conflicts' column displays "XYZ will be replaced" or "Create device" and does not "create a simulated device.
• If the Setup disk makes the SCXI configuration programmatically or an installer for the application, then more information about what is on the Setup disk would be useful.

• How to refine 24VAC for 1324 SCXI-1160

  Nice day

  I'm looking to refine the 24VAC (which is now surprisingly 28VAC).

  We use NEITHER-PCI-6030E, chassis SCXI - 1001 - 1160 & 1324.

  (Vi) code, I see just a relay is switched to power our module to test (wanted 24VAC).

  SC1Mod4/ch0 or 1.

  I guess I set the 24VAC with measure & auotmation explore? NOR-488. 2 interactive control? or the tool to Configuration of NOR-DAQmx?

  I am new to this kind of thing and I interview an old system...

  Best regards

  Koen.

  I do not understand your question about 24VAC. The scxi module is a simple relay card and the 6030 can generate high voltage. You must watch the patterns of your system to see what is used for a source of tension.

• Is the are recommended so that the SCXI installation cards in the chassis?

  I have a module SCXI-1001 with 3 cards scxi 1102, scxi 1 1520, 1 scxi 1126, 1 1162hv scxi and 1 scxi 1160

  connected to a PXI-1042 chassis with a pxi8108 and pxi 6289. Is there a recommended in the frame for these cards order?

  I use the 1520 to read the frequencies and the 1102 reading thermocouples.

  Hi Marko,

  Your SCXI module slot residing in is not important, but what is important is the module in which you use for communication.  Please follow this link which contains the rules for the connection of your SCXI modules to your DAQ hardware.

• Range of the signal DAQmx outdated?

  It could be me not quite understand the works of ADC express signal range.

  I use a chassis SCXI-1001, SCXI-1600 USB DAQ and a table of 1520 SCXI and 1314 for measures of constraints.  Within daqmx I have my range néc - 500 to 3500 uStrain with an excitement of the factor of 10V and pledge of 2.2.  After a recent test, I measured more than 4000 uStrain.  Real or not (we think maybe it's a sign of bad) I feel like the ADC must be on track to 3500.  What I'm missing here?  If the range does not reflect the real max and min then what it means.

  The range you define just tells DAQmx range values to cover.  With your configuration, you might be able to read much read more than 4000 depending on the configuration.  The given info, I just couldn't understand that the device is set on currently, but I'm sure you could dig a little in the specifications with your configuration to find out what Beach is using the card in your computer.

  If you feel that the material can act weird, there's a great KB help with measures of constraint in case of problems with your specific hardware.

  How can I solve the inaccurate measurements with the SCXI-1314?

• Acquisition of data VI

  Hello

  I'm a grad student and new labview program, I spent my two weeks to study the acquisition labview and data techniques in labview. So far, I am able to code a program like attachment (diagram) which runs essentially as the mode of execution of climax. I need to run the program indicates the trial period and record all data. I have neither SCXI-1001 peripheral hardware and labview 2013. I need to read multiple channels at once, although it seems to do with this code. The output as attaché is also not clear. I want the output to be totalled theme such as load, stroke, potentiometer 1 and Potentiometer2 etc. Please all help me to solve this problem. Your suggestions are very appreciated.

  Why on earth would you wire the Terminal iteration to the delay function?

• Can I use parallel mode and multiplex?

  Hello

  I have

  NI USB-6259 data acquisition Module (two connectors for cables two SCXI-1349, which connects the DAQ chassis)

  SCXI-1001 chassis

  3 modules of filter lowpass channel 8 SCXI-1143

  and

  an end before SCXI-1180 plate

  The DAQ has 16 channels of AI diff., I want to drive two SCXI 1143 in multiplexed mode (connected to connector 0 to USB-acquisition of data through SCXI-1349) and the other in parallel mode assigned to AI 8-15 (connected to the connector 1 USB-acquisition of data through SCXI-1349).

  The configuration is approved by MAX

  But when I run it with the software I get an error message indicating that a simultaneous sweep is possible error-223835. And that the selected channel is not in the task Error:-200486.

  (Such as the NI USB-6259) DAQ hardware can be attributed with channels 0-7 in multiplexed mode (multiplexing two SCXI 1143 8 Channel) and the rest of the channels in parallel mode for SCXI adapter? NEITHER USB 6259 must connectors separated, but he is still regarded as a data acquisition card?

  What does the error say? I thought that I have configured for simultaneous scanning.

  Attached to this post is a photo:

  Top left: back of my case NI USB-6259

  Top right: view from the front of my chassis with three SCXI 1143

  Below: Rear view of the chassis. Two SCXI 1249 are connected to two cards. One card must be run in parallel mode, two in multiplexed mode.

  See you soon,.

  Alex

  The following connection States:

  "In parallel mode, you can use that one module by hardware DAQ digital; You must connect all other modules in the chassis, in series, or parallel mode to a different DAQ hardware. »

  What SCXI Modules are capable of running in parallel Mode?

  http://digital.NI.com/public.nsf/allkb/3D45A66A691E4BD886256A6C004A4313?OpenDocument

  So you need a separate DAQ hardware for each module.

• LabView Thermocouple temperature readings

  I use the SCXI-1001 with SCXI-1102 and SCXI-1303 (LabView 8.2) in record temperatures of thermocouples type k.  My problem is that the temperatures that I see on LabView are off by about 5-10 ° c. AND they stray +/-10 ° c throughout the day.  What I've read, I think that this could be linked to the CJC.  Right now, I just CYC Source set "Permanent" with a value of "25".  I can make adjustments to it to help with the lag, but the drift just of temperatures throughout the day and the readings are again incorrect.  The room temperature changes somewhat in the region where I have this configuration, and drift in temperature seems to be linked to that.  For any help or suggestion would be appreciated. Thank you.

  Hi Zawer,

  Your SCXI-1303 module has a welding temperature sensor cold precision thermistor, so the 'Integrated' parameter must be supported.  Try resetting the 1102 able and Automation Explorer, then restart LabVIEW.  Is thrown this error yet?
