• Measure the frequency of the pulses PXI-6624

  Hello.  I work with a PXI-6624 and am interested to make measurements of pulsed frequency for frequency and duty cycle on its inputs using DAQmx.

  When I go to create the virtual channel, however, I have error-200431:

  "Physical channel selected does not support the type of measure required by the virtual channel you create."

  ' Asked the value: pulse frequency.

  «You can select: frequency, period, pulse width, period of Semi, separation of the two edges, Position:...» »

  Is this card really not capable of doing these measures of pulse frequency?

  Yes, the "Pulse" (not to be confused with "Pulse Width") measure was introduced with STC3 of OR including CompactDAQ and X series devices.

  Measuring the pulse:

  

  However, you should always be able to measure the frequency and the duty cycle on your card with a half measure:

  The half measure:

  

  The images are in the X Series user manual.

  The difference between these two modes boils down to how the data is stored and implemented in buffer on the map - with the period semi method that the material does not distinguish between high and low samples and puts everything in a single buffer.  However, if you start the meter on the song (see below the node property), then you would know the order of low and high samples in software, and are easy enough to calculate cycle frequency and the duty of this.

• Wiring - PXI-6624

  Hi all -

  I have a request that I need to use a meter, we chose PXI-6624.  I'm really good with the rest of the material, apart from FPGA and RF meters are only lines that I've not used.  I'm running into some difficulties to understand how to configure my son on the 6624 and thought I'd ask here.

  I have an optical sensor (Monarch Instruments model ROS) that I'll have to watch the impulses on.  Its got 4 wires coming in the distance, a commune, a signal, a + V excitation (10V) and cable shielding (IE common).  I am also connected to an SCB-100 using their 100 flex cable.

  The thing I'm getting hung up, each meter on the module has 10 terminals assigned to him.  I continue to go through the manual, but I can't understand.  Went to NEITHER and the engineer he basically just copied and pasted the same part of the manual I did not understand.  If you ask for more details on the portal + / for example, the response I got was 'you can if you want to signal that you are using the pins of the door the door '... I guess that means that you can use these pins as a switch to take the signal or not, as you would the door on a FET used as a switch.  Just one example of how detailed responses are :-)

  In any case, I am reading and looks like each entry almost has multiple functions that overlap, but I'm unable to digest it.  Can someone help with the wiring on this?

  Cordially - in the short term, I have 1 sensor which will include rpm for 1 pulse per turn.  We also want to make direction which will need a second sensor with the set of two upward slightly as the squaring function requires.  Only two will have only 1 pulse per revolution, rather than an encoder with say 120 pulses per rev.  Should subsequently over them both, but I think that if I can figure out exactly one that I can use it to understand the rest of the installation on my own :-)

  Thanks a bunch!

  External connections:

  Commune of sensor connected to the source - meter

  The connected sensor signal to source + meter

  Any signal of door that you would use for this application would be generated internally by using another counter and then routed internally to the door of the counter which counts the external pulses.  In this case the door signal would provide a specific window of time count impulses.  An example could be measure RPM.  If you decide to measure the pulse for a full minute, with accuracy what a minute?  If you do not exactly one minute, your RPM will be incorrect.  Calendar of the software will not work.

• PXI-8184 restarts junk

  Hi all,

  This is my first post so I apologize if I missed something and also for my English

  We have conducted many years successfully applying LabVIEW RT (version 8.5.1) on a PXI-8184 (2 PXI-4472 modules, 1 module PXI-6624, chassis PXI-1042, 1 module PXI-6224). In our maintenance protocol, we loaded a picture of the traditional configuration of PXI (that we always use), using the system replication tool, as we usually do.

  A few days ago, we did it. After the application has started running, suddenly restarted PXI. Since then, the PXI application always restarts junk.

  This does not happen if we run the application directly from LV (no build request).

  It is important to mention that we have no trace of falls or visits that could affect the integrity of the PXI system. We tried different solutions, but nothing happens (resetting, reinstalling,...).

  First it hardware or software explanation to this? (watchdog, CMOS).

  I would really appreciate any comments.

  Greetings.

  Roberto.

  
  

• How to count the edges within the great period of door?

  Hello

  I use a PXI-6624 counter/timer in Visual Studio C++ with Meassurment Studio.

  I want to count the edges on a signal within a high period of an input signal.
  I found the documentation entries "CTR n CBC", "CTR n GATE" and "CTR n to THE.

  My idea is simply configure the counter 0 to count the edges on CBC by blocking via DOOR.
  can be an example to my problem in the installation of nor, but above all I do not understand the description of landscaping.
  to find a good example, you must know the name of the function you want to use.
  can someone tell me the good examplename for my problem?
  What call configuration should I use?

  a little less important than my first problem is a similar.
  I want to count the edges on a signal between a start trigger and a relaxing stop.
  SRC-> signal
  DOOR-> start signal
  To THE-> the stop signal

  I found a way to count the edges of the internal clock between start and stop (2 Seperation of edge), but not for an external signal.

  can someone help me with this? especially with the first.

  Hi John,.

  Thank you for your help. It works very well.

  I had a few problems with how the timebaseSource should be implemented.

  Finally, I found the solution.

  for those who do not want to search long for the code, it is here:

  Create the task
  
    CNiDAQmxTask ("CITask") m_task;
  Create the meter inlet channel
  
    m_task. CIChannels.CreatePulseWidthChannel ("PXI1Slot16/ctr0", "",)
  
           atof (minimum), atof (maximum), startingEdge,
  
           DAQmxCIPulseWidthUnitsTicks);
  Retrieve the channel to change
  CNiDAQmxCIChannel chan is m_task. CIChannels.GetAll ();
  Fix the DOOR Signal
  
    Chan. SetPulseWidthTerminal("/PXI1Slot16/PFI38");
  The value of the Signal SOURCE counton
  
    Chan. CounterTimebaseSource = ' / PXI1Slot16/PFI39 ";
  CNiDAQmxCounterReader myCounterReader (m_task. Stream);
  
    Double measuredWidth = myCounterReader.ReadSingleSampleDouble ();

• SMU system controlled by PC

  Hi all

  I have to do a test system optimal hardware configuration OR for an application where the system should simulate Serial interfaces, interfaces to MIL STD 1553 and analog, Digital O/Ps & I / PS. Modules OR for the best match for this requirement were NI PXIe4322, 4300, 6363, PXI-6624, 8430/4,8431/8, Pickering two rtd PXI cards and a card of 1553 PXI SMU-1075 controller SMU 8840-frame. BUT this current price of configurations will on budget than we expected. for this reason I think to change this part and part PCI system in 6363,6634 tax SMU system, serial interface cards and card MIL 1553 with a PCI/PCIe platform and keep the rest of the map with the SMU platform chassis and eliminating controller SMU 8840. So can I use MXIe controllers to implement this system of type test so that I can put all the pci cards in a high-end modules SMU and PC and industrial PXI chassis SMU (1065/1075/1078 one)? If so please guide me what controller MXIe to choose and what would be the compatibility problems that may occur with this type of system in the future.

  Thank you

  My experience with USB has been nothing else to headaches.  So I wouldn't go the route of USB.  Normal PXI slots can also accept the cPCI, so you could look for those as well.  If you just need a very simple map of 1553, I'd go with 1553 Excalibur cPCI card.  I used their cards and they work fine.  Drivers LabVIEW need a cleaning, but they can be used.  This card is a simple send and receive, so if you need to do some testing of weird signal integrety (I don't remember the number of test at the top of my head), this card will not work for you.  But this card was sever thousand dollars less expensive than the GOAL cards, I also used.

• Using SMU 6612 to measure PXI-6528 pulsewidth channel - channel is not available.

  Hi all

  I use SMU 6612 card counter to measure the pulse width of the signals to PXI 6528 DIO card. These two cards are in the same chassis PXI (NI-SMU-1065). I could measure the pulse widths using the example LabVIEW 2013 Counter - pulse width of reading and (over) frequency example of .vi. However not all channels of the PXI-6528 map appear in the drop-down list of channels on the pulse width can be measured. Try to connect any other channel that those which are available in the drop-down list returns the error. On the PXI card port 6528 0,1 and 2 are entered ports and port 3-5 are output ports. I can measure the pulse on port 0, 3 width and line 0 port 1 and 4.

  Can someone explain to me why don't see port 1 or port 2 channels in the drop-down list or force the VI to measure the width of pulse on these channels?

  I can plug PXI-6528 external input channels SMU 6612 counter input channels and measure the pulse width, but if possible I'd like to avoid the external wiring between the 2 cards.

  Probably not.  Unless the routing plan is in fact reversed as it seems a bit sorta that.  As stated on my system, you can route * of * a port of entry * to * RTSI, or you can route * of * RTSI * to * one output port.  This does not make much sense to me, but that's what I see:

  

  If the routing card * is * reversed, your only likely workaround without physical wire would be to generate impulses in question of port 3.  It's pretty clear that 1,2,4,5-tetrachlorobenzene ports have no ability to interact with the bus timing, physical wiring would be the only option.

• PXI-1033 not detected until the pc is rebooted

  We have a chassis NI PXI-1033 with a PXI-5114 and PXI-4072-PXI-6221, fist, that he had failed to recognize and install drivers for motherboards. The search in the knowledge base, I tried workaround by disabling the PCIe mode ' bcdedit/set pciexpress forcedisable' command and rebooted the pc. Then the system recognized and installed the drivers for all the hardware.

  Disabled the PXI system at the end of the day. The next day, after activating the system, he did not recognize the hardware, returned changes to aid 'bcdedit/set pciexpress by default', then restarted the pc. Once again the material have been recognized.

  I tried to change the configuration on the PC BIOS, without success. The PC is an ACP-4000 of Advantech. We need to restart PC after a cold start so he could recognize the hardware and load drivers.

  Is this normal?

  Concerning

  The PC is under Windows 7 Pro. I searched on google for similar problems, where I found one where someone said that the culprit is that the chipset of the motherboard not give not the PCIe card delay what he needs on a start cold in order to be recognized. A reboot gives the time required and the card works.

  Hey djo.

  If I understand your description, the best sounds of relaxation as it can be a trigger of hysteresis with coupling AC trigger in order to eliminate the effects of your DC signal. You will then be able to adjust the amplitude of the noise that you are looking for as the level to which you want to trigger off. You can find information about the options available with the help of scanners trigger high speed OR under Fundamentals > trigger.

• While with PXI-5122 digitizer loop counter

  Hello world

  I am a beginner of products NOR. Currently I use the PXI-5122, 2014 Labview for the ultrasonic signals. I have a problem when you count the number of signals using an external trigger (by a function generator) source. When I trigger the digitizer under 50 Hz, the meter is working properly (a single trigger = a signal). With a frequency greater than 50 Hz of trigger, the meter is malfunctioning. For example, with the shutter to 50 Hz and 500 number of signals, the counter takes 10s to get data. But, with the trigger of 100 Hz and 500 number of signals, the acquisition time was always around 10 s.
  You can see the code in the file attachment.

  Please let me know if you have any suggestions or recommendations for my situation, I would appriciate that.

  Thanks in advance!
  Best regards
  You

  WorldALoneMe,

  Looking at your code, you're software re - trigger your device.  With your Setup, you configure the digitizer to hold a single record acquisition in your "A - Scan.vi".  This VI opens the resource OR-SCOPE, configure, captures, returns the data, then closes the resource OR-SCOPE.  It then does this for each unique A-Scan that you do and would be the reason that b Scan.vi takes so long.  It appears then that fewer than 50 Hz, this reset any software and reconfiguration and the acquisition can occur without missing a trigger, but more than that, your triggers occur faster it takes to do these things.

  What you need to do set up the digitizer to a multi-record acquisition.  This is done using the 'niSCope configure horizontal timing.vi' and wiring in a number higher than '1' in the entry "number of records".  "You can find an example of how to perform a multi-record acquisition if you open the Finder of example OR > material input and output > Modular Instruments > NOR-SCOPE > Getting Started > niScope EX Multi Record.vi.

  In this example, the digitizer is only once configured, and it returns all the documents requested at the same time.  For your application, each record would be a simple Scan of A, and then if you configure 500 files, your B-Scan would be 500 wide.  This time allows the material to rearm between triggers that is much faster to do it in software.

  For a verification of more complex example out (in the finder of the example) "niScope EX Multi record go get more available Memory.vi"

  Kind regards

• 5154 PXI trigger on the external input

• Incompatibility of pilot PXI 5105 and unable to be detected by OR-SCOPE FPS with NO-SCOPE installed 14.1

  I am setting up test bench and just add a PXI-5105 card to my chassis SMU-1078.

  I currently have NO-SCOPE 14.1 installed on my PC host and target RT.

  When I try to run the Test panels in MAX, I get the following error:

  

  If I try to launch SFP-OR-Scope, it does not detect the card of the scope:

  

  The map seems to indicate as normal in my remote systems in MAX.

  For the host, the Installation of NOR-SCOPE includes:

  • Configuration support 14.1
  • 14.1 development support
  • 14.1.1 duration

  For the target RT, Installation of range OR watch as 14.1.0.

  I even checked in the feature add/software for the remote system see if a driver incompatibility was actually present:

  

  I have also confirmed in the Readme that PXI-5105 is supported OR-SCOPE 14.1.

  I'm kind of dead in the water on other ideas to investigate on concerning the system is behaving properly with the new card.  Other ways suggested for study?

  I continued to play with setting up more and find my VI has been targeted my Windows host instead of the goal of the RT.  I'm nowable to see my map of scope 5105 now through Labview + RTM.  Thank you for tolerating a newbie.

• The streaming of data in c (PXI-5421)

  Hello

  I do the data streaming in C by PXI-5421 follow this instruction: http://zone.ni.com/reference/en-XX/help/370524R-01/siggenhelp/streaming/

  Here's my psudo code:

  1 set the amount of memory shipped to use for streaming

  waveformSize = 1048576;

  short * CurData [16];

  checkErr (niFgen_init (resource, VI_TRUE, VI_TRUE, & vi))

  checkErr (niFgen_ConfigureChannels (vi, ChannelName)); ChannelName = '0'

  checkErr (niFgen_ConfigureOutputMode (vi, NIFGEN_VAL_OUTPUT_ARB));  //Arbitrary mode is used

  checkErr (niFgen_ConfigureSampleRate (vi, SampleRate));   Rate of sampling = 40e6;

  checkErr (niFgen_AllocateWaveform (vi, ChannelName, waveformSize, & wfmHandle));  Allocate memory for broadcast borad

  2. identify the waveform streaming

  checkErr (niFgen_SetAttributeViInt32 (ChannelName, NIFGEN_ATTR_STREAMING_WAVEFORM_HANDLE, vi, wfmHandle));

  checkErr (niFgen_SetAttributeViReal64 (vi, VI_NULL, NIFGEN_ATTR_STREAMING_WRITE_TIMEOUT, 10.0));  Set TimeOut = 10 s

  3. fill the waveform continuous initial data

  for (j = 0; j<>
  fread (CurData [j], sizeof (short), waveformSize/16, PlayedFile);  Read data from my saved file
  checkErr (niFgen_WriteBinary16Waveform (vi, ChannelName, wfmHandle, waveformSize/16, CurData [j]));
  }

  4 start generating the waveform

  checkErr (niFgen_ConfigureOutputEnabled (vi, ChannelName, VI_TRUE));
  checkErr (niFgen_InitiateGeneration (vi));

  5 write a waveform data block. (Optional) Monitor available memory that generates the waveform

  {}
  niFgen_GetAttributeViInt32 (vi, '0', NIFGEN_ATTR_STREAMING_SPACE_AVAILABLE_IN_WAVEFORM, & FreeSpace).

  {if(FreeSpace>=waveformSize/16)}
  fread (renewData, sizeof (short), waveformSize/16, PlayedFile);

  checkErr (niFgen_WriteBinary16Waveform (vi, '0', wfmHandle, waveformSize/4, PlayData));
  //}
  } while (1);

  I properly generate first 1048576 points of data. However, I'm stuck in writing new data in my space of memory onboard.

  The error message space in continuous waveform has not become available within the specific period, and appears after 10 sec which is my time-out period.

  If I check my available space via the property NIFGEN_ATTR_STREAMING_SPACE_AVAILABLE_IN_WAVEFORM, it never increases.  Did I miss something? Can I work in arbitrary mode for data streaming?

  Any suggestion is appreciated. Thank you!

  Looking at the example LabVIEW/CVI, it seems that you are on the right track.

  If you remove the Do / While loop, do you still 1114112 samples? In other words, samples of 1048576 (1048576/16)?

  What is the value returned by ' niFgen_GetAttributeViInt32 (vi, '0', NIFGEN_ATTR_STREAMING_SPACE_AVAILABLE_IN_WAVEFORM, & FreeSpace)? "

  I have attached the CVI example in this post. It has many additional functions that change the GUI of the CVI, but ANY function calls should be the same. Is the only thing that is considerably different that they set a number of rehearsals and use unique relaxation mode. I would go ahead and change your code to be similar in order to ensure that it is no hardware problems. Then I would try to generate and disseminate a sinusoid first before trying to use your file. I hope that we can refine all the problems.
