• Problem with digital I/o read and write in CVI

  I have a PXI with PXI 6225 Renault installed box. For some uses, I wired 4 lines of digital port 0

  for its 4 top lines so that the output digital on bottom lines can be read as a digital input on the top lines.

  In the CVI program I have set up two input and output of tasks as follows:

  Enter task:

  DAQmxCreateDIChan (digitalInputTask, "PXI1Slot5/port0 / line4:7","InputLines", DAQmx_Val_ChanForAllLines ");

  DAQmxCfgSampClkTiming (digitalInputTask, ' AI/SampleClock ", 4000, DAQmx_Val_Rising, DAQmx_Val_ContSamps, 2000" ");

  Output task:

  DAQmxCreateDOChan (digitalOutputTask, "PXI1Slot5/port0 / line0:3","OutputLines", DAQmx_Val_ChanForAllLines ");

  DAQmxCfgSampClkTiming(digitalOutputTask,"ai/SampleClock", 4000, DAQmx_Val_Rising,DAQmx_Val_ContSamps, 2000));

  DAQmxCfgOutputBuffer (digitalOutputTask, 2000);

  I also started a task of analog input to ensure that the analog "IA/SampleClock" sample clock is running, and I check

  as I interpret the correct analog data of my analog lines.

  Here's the problem:

  I write 2000 identical samples of zero for the 4 lines (port0/$line0... (3) with the following command:

  DAQmxWriteDigitalU32 (digitalOutputTask, 2000, 1, 10, DAQmx_Val_GroupByChannel, sampleArray, & writing, NULL);

  After a while, I try to read the 4 lines (port0/4... (7) using the:

  DAQmxReadDigitalU32 (digitalInputTask, 2000, 10, DAQmx_Val_GroupByChannel, scanArray, 2000, & read_num, NULL);

  but the values returned in scanArray are nil!

  If I replace the digitalInputTask by digitalOutputTask in the above function call, I get the good samples rewritten

  (do not know how the 4 lines below that are configured in output mode can be read back! could it be just read buffer?)

  I don't know that the hardware configuration is correct, because when I try to emulate this feature in Labview, it works.

  (I use an output data acquisition assistant to write down the 4 lines of port 0, using a digital wave of entry, then)

  top reading 4 lines with the help of one Assistant DAQ to enter a digital waveform VI.

  In another test, I have 4 lines below in CVI, put on stop my CVI program, start a simple Labview VI to read from

  upper 4 lines and I can see the values I just write in CVI).

  Any idea what could be causing DAQmxReadDigitalU32 to read only zeros in CVI?

  I compared my settings in CVI with parameters DAQ assistant in Labview and tried to make them identical, but nothing helped.

  Thank you

  Hello Doug,

  Thanks for the reply.

  It works to read a Boolean value. How to read the table of Boolean?

  Kind regards

  For a table you can either do:

  (1) myarray [] bool = contextOfTraceMsg.FileGlobals.GetValVariant ("myarray", 0);

  Or

  (2) using GetNumElements() and GetValBooleanByOffset().

• Read and write in a PARAM. CMI file?

  Hello

  I have a problem with the reading and writing of a PARAM. CMI file. If I remove the "Section" block at the top and move the first element to the top, I can read very well but I can't get past the sections.

  Section ex: "[Core]" if I delete that and everything move upwards no problemo. Any help would be appreciated.

  Yes. Oops. It was the air code. You would use URLLoader and URLRequest instead of FileStream and file. My bad. For example, if you have done the URLRequest thing and got your file in a first function URLLoader I gave you become:

  private void loadCMIFile(evt:Event):void {}

  var cmiLoader:URLLoader = evt.currentTarget as URLLoader;

  try {}

  parseCMI (cmiLoader.data);

  } catch (err: error) {}

  trace (err.name, "\rUnable to parse the selected file." + err.message);

  }

  var lessonStatus:String = "Lesson_Status."

  trace (CMI [lessonStatus]);

  }

  Just parsing the text, we can make an object or an XML in flash that contains the data in a readable way, but if you want to rebuild the IJC to Flash file so you will need to know what these headers. I mean if there is no information and they are not text, you will need to know the number of bytes that they are and then put aside in a ByteArray so that you can transfer them on your later output file. Or you need to find the specifications of file for them - they could be full of location bytes or ID tags or who knows.

  Assuming that we have to fear is the analysis, I would like to make a suggestion. Maybe you want your data to a XML in Flash:

  private var cmiXML:XML =

  ...

  ...

  To save time to look for keywords, you can configure a set of vectors that contain

  private const cmiCore:Vector. = new ["Student_ID', 'Student_Name',"Output_File"... etc.];

  private const cmiCoreVendor:Vector. = new ["CoursePath"];

  private const cmiEvaluation:Vector. = new ["Course_ID', 'Comments_File', 'Objectives_Status_File'];

  etc...

  Then you can read like this:

  private void parseCMI(string:String):void {}

  analyze the main

  for (var i: int = 0; i< cmicore.length;="" i++="">

  var regExp:RegExp = new RegExp (cmiCore [i] + "=");

  If (regExp.test (string) {}

  cmiXML.core.child (cmiCore [i]) = extract (string, regExp);

  }

  ]

  }

  private void extract(str:String,_re:RegExp):String {}

  var value: String = str.substr (str.search (re));                    makes a string that starts after the "equal" sign

  value = value.substring(0,value.search(/[\r\n]/);           cut the string at the first jump of line or return transport

  Returns the value;

  }

• Read and write of series Basic can't read a second time

  Hi, I'm developing my own VI to write and read an iRobot Create.  I based my vi off the coast of the basic series example write and Read.vi I found (on LabView 8.0).  When I run my vi I am able to read information from the beginning to create, but I am unable to read a second time (after a write command).  The second reading should be the same as the first (I checked with the help of another program that is linked to the creation).  I am new to using LabVIEW and I was wondering if there is a common mistake made by trying to implement a series of read and write.

  Thank you.

  First of all, to debug your orders with a program such as Hyperterminal. If it works there, then it should work in LabVIEW. You may need to send a carriage return and newline (\r\n). Your code is not currently set up to do.

  Only do something when a button is basic programming LabVIEW. You can use a simple while loop with a façade that Boolean connected to an instruction box. If you have anything other than the basic version of LabVIEW, you should use the structure of the event. Look at the examples that come with LabVIEW.

• Satellite M30X-165: Mat * a UJ - 831 S is not read and write any DVD

  Hello

  the next problem is sticky on the laptop Satellite M30X 165 with the burner Mat * a UJ - 831 S: it can read and write CDs, but is not able to write them to DVD or even read some of the ones I've burned and also read in the same drive. Even at the start of the DVD, it does not start from the recovery DVD, the player starts and slows down very quickly.
  Without doubt, it must be put at the service of repair or someone has other suggestions?

  Could you please tell me how long the repair takes (I know what it takes to install the desktop temporarily used).

  Thank you

  Using burning software, it detects the DVD, but invite you to an "error of calibration power (037303).

  Hello

  If you cannot use recovery media, I guess that the drive is defective and must be replaced.

• Using the same interface CAN read and write

  Hello.

  Can I use the same CAN interface to read and write?

  For example:

  I send you CAN frame using CAN1 to my MCU.

  IF MCU confirmed the order of receiver it immediately sends the echo return command and there different ID to send the command.

  I tried to use CAN1 output framework and then reconfigures CAN1 to frame in queue and retrieve the frame of the echo.

  But it seems that I was always missing. The 'framework of CAN' kept vi expire.

  When I used the separator on the outlet BOX in my configured MCU CAN1 for frame and CAN2 for chassis in and I managed to catch the echo framework.

  I think about 100 ms for the frame in response that will be sent after the order has been received. It takes longer for the NI PXI-8513 reconfigure? Can I still do it, or I have to use the separator?

  I wad jump to use an interface to read and write.

  Thank you

  Ok. I misread your notion of echo. I understand now. I'm sorry.  The code you posted seems reasonable.

  (1) did you notice on or off for the session?

  (2) what baud rate? You can add a parameter of baud rates for the property to be explicit node.

  (3) I don't remember the name of VI, but you can add a status of Comm Get after reading. This will give you some information about the bus - if errors were detected, etc. Which can be useful to help debug.

• TCP Read and Write at the same time

  Hello everyone,

  I have a question about parallelism in TCP connections.

  I know that it is possible to read and write on the same connection ID.

  So, if you ReadTCP and WriteTCP block each other, if you use the same TCP connection ID?

  Or to request more precise if I run two while loops, in parallel, with one end by calling WriteTCP and the other called ReadTCP.

  one of the delay of loops (or block) will be the other if both loops call their VI TCP at the same time right?

  The system is Windows 7 and Labview 2012.

  Kind regards

  Sebastian

  They are perfectly parallel.  Just write in one and read it from the other.  There is no conflict.

  See My TCP articles for more details.

• How to read and write attributes using the API?

  I'm trying attributes of access (read and write) of the following:

  SequenceFile

  Sequence

  The sequence steps

  When you look at the documentation of the API, TestStand, the following functions are available:

  PropertyObject

  Properties

  Attributes (read-only)

  HasAttributes (read-only)

  Methods

  DisplayAttributesDialog

  I tried to use the SetValString and GetValString commands using the reference of the attributes, but it does not seem that the data is stored in the file.

  I can't find the following information in the TestStand API:

  1. Where the attributes are stored in a property object?
  
  
  2. How can we access through the API?

  No advice and no information is appreciated!

  You must increment the number of changes to the file after that editing the sequence editor (or UI) won't refresh or mark the file, as amended. Use sequenceFile.AsPropertyObjectFile (). IncChangeCount().

  SequenceFile attributes are stored in the SequenceFile.Data, not the object of SequenceFile object. You can change them in the Advanced tab of the properties of the file sequence dialog box.

  Hope this helps,

• Read and write to a port

  Hello

  I tried to read and write in a port using .net 3.5 example codes that are supplied with the controller. Examples\DotNet 3.5\Digital\Generate Values\Write Dig channel and channel digging reading. Regardless of the value that I write I always get a positive output reading and all the bits are high on the channel. To reporoduce the problem simply run two programs at the Dig sametime writing and reading Dig Channel channel. Set the port to Dev1/Port0 / line0:7 in the two tests and write a negative value for any or all channels. When you read the values, the values are all positive. I tried using the example of code in VB and I get the same results. Please note that the regulator is working properly when I run the test, measurement and automation. I looked at the Forums and I found the post to:

  http://forums.NI.com/T5/Measurement-Studio-for-VC/basic-questions-about-PCI-DIO-96/m-p/242296 The name of the article is basic questions about PCI-DIO-96 and it says that the values written should persist. Any ideas on what I can do wrong?

  Thanks, Magued

  This is a LabVIEW and an example VB that illustrate the use of tristate to switch between the input and the output. The output setting will allow you to drive the liine and re-read what you wrote. The read setting will allow you to read an external digital signal. Please excuse the fact that these are examples of rough and informal.

• GPIB read and write commands of Agilent 54642 oscilloscope

  Dear friends,

  I would like to acquire a waveform of Agilent 54642 ocsilloscope in the LabView 7.1 via GPIB program. Can anyone mention the GPIB read and write commands for the oscilloscope even?

  Furthermore, on the subject of the LabView program, is it fair to place blocks to write two GPIB followed by a single GPIB read block (everything series), as well as an indicator, in order to check the waveform in LabView?

  Kindly help me with your answers...

  Look forward to y...

  Thank you very much in advance...
