The VISA read function is not read the bytes specified in the buffer zone

I created a program that continuously acquire data of the inverter. But, the "Reading of VISA" function is not rreading all bytes of the buffer, which is a big problem because the way my work programme is it will extract the specific buffer bytes and convert these values in voltage and current values.

I specified the number of bytes that I want to read the buffer as for example I want to read 21 bytes. But, even if there are 21 bytes in the buffer, the read function VISA read only 9 bytes. Im not using any character of endpoints so this is weird. I'm using LabVIEW 2011.

Is attached a photo of my program and the results.

You still have the active stop character.  You must connect up to a FAKE at the entrance of termination character activate on the Serial Port to set it up.

  • The value read by visa read that VI is not correct!

    I design a labview program to control the Agilent E5072C Network Analyzer. When I want to get the value of this instrument, I use VI "VISA read" listed in the plate. However, the value read from this VI's latest measurement of time value. For example, the last time that the read value is 1.0 db, and this time the measurement value is 1.2 db. But when I use 'VISA read' VI to extract the value is 1.0 db.

    Agilent also provide a VI for this device to read the measurement value and she was always correct value. If someone could tell me why? need to do any action before the value read from this instrument if I want to use VI "VISA reading" instead of Agilent VI?

    You are probably reading too quickly.  Reading it in NOR-MAX, you do it by hand, it takes more time.  When you do that programmatically, it is "instant".  Try using the * OPC? command to activate your order in a query.  He returned then a '1' in the buffer.  Read the '1' and then create the command fetch.

    For Dennis:

    I've had bad experiences with the drivers provided by the manufacturer to the point where I don't even try to use more.  But Agilent is also anal about their drivers, because they are on their books, they should pose no problems.

  • VISA read lose characters beyond the end of the output string

    Hello

    I wrote a VI to take a string of output data of an ardunio Uno and analysand. I use the vi read Visa to enter the output channel of the unit. In the end I will connect a device that actually gives the value in this type of format string: (#80212164,2289,2292,2296,2300,2328,2289,2297,2290,2300,2308,2292,2295,2298,2289,22,24,0 *).

    So after a large number of loops, the program starts to drop the last characters of the string that it generates. If the string of Visa Read output reads something like (#80212164,2289,2292,2296,2300,2328,2289,2297,2290,2300,2308,2292,2295,2298,2289,22,24,). The only way to solve this problem, once it has occurred must completely close labview (completely). Once I open again and start the program running, all is well in the world.

    Has anyone had this problem? I tried to debug it in different ways and the only weird symptom I have other Visa Read function lose a few characters of the string is the fact that by looking at the bytes to the Port after I read visa, is that she starts showing five bytes instead of zero.

    my last attempt at resolving this issue is attached.

    Note: The Ardunio outputs a string of this format every 2 seconds with the values being incrimental on a specified range. (80212164,2289,2292,2296,2300,2328,2289,2297,2290,2300,2308,2292,2295,2298,2289,22,24,0 # *)

    You can configure the * your character of termination if your Arduino does not send the carriage return or line feed.  Use the configure a Serial Port to ensure that your settings are correct.  You can also use this VI to increase your timeout so that you no longer need your waiting.

  • Visa read write on port series independently and at the same time!

    Hi all!

    I need to read and write data to and from a serial port (rs232) independently and simultaneously .

    I'm sorry that I can not put a picture of that, but it's very simple:

    I used "set up the serial port" and forwarded to two while loops, the resource reference.

    a loop is reading data and the other loop is writing data to the port.

    the problem is when the playback loop (function serial reading) waiting for data - it blocks the other loop to run (writing of the serial function is blocked).

    I searched the forum and find this visa open function has 'duplicate session' option - that's what I need?

    If true, can someone explain exactly how to wire and use it in the right direction?

    Thank you very much.

    Guy.

    OK, I found an example that solved my problem: a VI called   serialduplicatesessions.

  • How to stop the series 'VISA read' the sends packets instead of bytes available.

    Dear Labvillians,

    Highlights:

    How can I stop series "VISA read" send me packages rather bytes?

    Background:

    I have a system which publishes series of 14 bytes on a semi-regular interval packets.

    At busy times, the producer of these these queues of data packets, effectively producing Super-paquets multiple of 14 times larger than 8 packages (112 bytes) bytes.

    My protocol handler is designed to process bytes, packets, or packets Super.

    Now, my request has multiple devices and the order of message processing is essential to the proper functioning.

    My observation is that read VISA waits until the end of a package / super package before moving the data to the application code. (See chart below)

    My expectation is that VISA read should give me bytes available, get too smart for itself and not wait for a package.

    .

    I noticed this on PXI, PC shipped, PSC and, more recently, cRIO

    I've experimented with Scan interface the cRIO rate, which helps to reduce the backlog of packages but don't decide to package under read byte.

    I understand that a solution is FPGA code write to handle and pass the bytes by R/T-FIFO, and there are some great examples on this site.

    Unfortunately, it does not help with FPGA devices not.

    I have also dabbled in the event based sequential reads, but he is evil on vxWorks devices.

    Any help is appreciated

    It is helpful to sometimes talk to yourself.

    I hope that is useful for someone sprinkle in the future

  • Visa reading reads all bytes to the port

    I have a camera that I communicate via the Serial Port. I have a standard communications protocol. For a particular command, I know that the exact number of bytes expected in return. I send my order. I see the correct number and exepcted to bytes in the port. I then read the number of bytes in the port. However, the VISA read returns only the first two bytes.

    I contacted success with this camera and this Protocol for more than 130 commands unique and different. There are only about 6 orders in which the read visa does not read all the bytes in the port. Anyone know why that would happen?  I expect to see 6 bytes. I see 6 bytes. I have visa read the command with 6 bytes. The visa read returns only the first 2 bytes. It's very very frustrating. I can do this exact process even with a different command. I expect 45 bytes of this command. I see 45 bytes with this command and I read 45 bytes with this command.

    I don't think that it is device connected as I can converse with success with the same camera on the same computer with the same cable of connector using non-LabView. It seems to be a problem strictly related to labview and VISA read the order. If someone could help that would be greatly apprecicated.

    Thank you.

    What is the exact byte stream that await you in return with this command?

    Instead of opening VISA, use the configuration Serial Port VI.  In this way, you can override the default values.  It looks that your instrument using all the defaults VISA of speed in baud rate, start and stop bits, etc.  However, in the VISA software, there is a failure to use a termination character, and this character is 10 (0x0A).  If you use the configure Serial Port, you can tell the pilot VISA do not use the stop character.

  • VISA read where you don't know the number of bytes?

    I work with a VISA resource via the USB port that reads in the results of printf (% lu % TSP %d)) of a microcontroller. These results are as ASCII numbers, their length in bytes is unknown. Numbers * should * be not more than 3 digits, but I can't know that for sure. Reading VISA won't let me the number of bytes unwired, so should I join just a high constant let him? Or is there a better way?

    1. do you have the microcontroller send a character to end of line (0xA on the ASCII table) at the end of the printf.

    2. turn the stop of the session VISA character and the value it is 0xA.  You may need to perform this task via the VISA property node.

    3. playback VISA to read more bytes than you tell never expect to get.  VISA playback will stop reading when it detects the termination character (End Of Line).

  • How to run vi continuous when the VISA read timeout happens

    Hello

    I'm using LabView 2010 through a series of Agilent 6000 Oscilloscope. The Oscilloscope reads data from another experimental machine which will occasionally fail due to failure of the sample. When the machine breaks down, it ceases to send signals to the oscilloscope and leads to the error timeout of read VISA and the vi It is over.  Is it possible that I can run the vi permanently when the error occurs? For example, when the error occurs, it stores the error in the thread of the error. When the vi read the error code of the wire, it sends a command to stop my experimental machine then stop the vi.

    So far, it stops simply during the execution of the visa, playback function. In that case, why do we mistake in and out? Vi stop just when the error occurs.

    Thank you

  • No VISA Read reading all the bytes available and ordered

    Hi all

    I use Write.vi VISA and VISA Read.vi to send and receive packets of bytes to and from a processor.  Generally, everything works fine.  I put a loop repeats until he sees at least 20 bytes to the port, then I VISA Read to read 20 bytes.   However, when I receive some packets of bytes, my property node indicates 20 bytes to the port, I ask VISA Read to read 20 bytes, but it reads 13 bytes and leaves seven bytes to the port.  If I run the read operation again, it will read their remaining 13 bytes.

    Any ideas on what might materialize this project?

    Thank you

    OK, I thought about it.  I put 'Stop character activate' in 'VISA configure Serial Port' to 'False', and all my problems disappeared.

  • want to use visa read only when the pieces is in port

    Hi all

    I do a lot of serial data communications and visa read doesn't have an undo feature.  Heres so the question.  If I'm in the middle of the read visa, set up the picture picture and block, and I press the stop button, I have to wait for the visa reading for timeout, in this case 2 seconds, before I can move to the next step in the shutdown sequence.  Now, I know, there is a way to use the events of specefic bus, but I have yet to find a good example.  Any help or advice for a workarond for that matter?

    Thank you

  • Visa read byte at the port

    My visa to read, I feed in the bytes in the property node port as input for the number of bytes to read (it's 4 bytes).  However, the output of the read visa give only 2 bytes.  It seems that a few bytes have been lost during the read operation?  Why is this?  It is an easy to see what is in the buffer of the serial port?  Thank you!

    Yik

    You likely the session VISA set to end readings when he sees a stop character and VISA reading is to see the stop character, and ending the reading, regardless of the number of bytes you told to read. If you want that it explicitly read that much then you must disable the option "Activate the stop character" in VISA set up a Serial Port.

  • The data read into the buffer HAVE lack samples at the beginning

    I use a box USB-6251. The program implements two channels of AI (read I and Q) on a single task and one channel on another task. The channel uses the ai\SampleClock as its clock, so that both are synchronized. C creates a digital pulse periodic rising edge (a clock basically) which is used as a trigger on an external function generator. The signal from the unit after going through some material, external signal processing is ultimately what is read by the channel of GOT it.

    We know from the relevant signals, they seem to be correctly synchronized scope. IE, the analog signal to read arrived on the channel of the AI of the acquisition of data more or less instananeously when the trigger is activated. If there is a delay, it is of the order of microseconds.

    However, when I read in the buffer of HAVE (repeated FiniteSamples), waveform, I always come back has a section of samples at the beginning that seem to be returned of the first actually read data-point (see attached image). This delay is of the order of milliseconds (it varies with each series).

    I want to totally eliminate this delay. The signal should be a sinusoid which begins to sample 0 and is continuous through until the last sample read.

    I put the code below.

    Installation program:

    Create analog read the task
    analogReadTask = new Task ("analogReadTask");

    Create the virtual channel for the component I
    analogReadTask.AIChannels.CreateVoltageChannel (initParams.AddrI.ChannelAddress, 'I', AITerminalConfiguration.Differential,-4, 4, AIVoltageUnits.Volts);

    Create the virtual channel for the Q component
    analogReadTask.AIChannels.CreateVoltageChannel (initParams.AddrQ.ChannelAddress, 'Q', AITerminalConfiguration.Differential,-4, 4, AIVoltageUnits.Volts);

    To set the clock for the analog readings
    analogReadTask.Timing.ConfigureSampleClock (string. Empty, initParams.SamplingRateHz, SampleClockActiveEdge.Rising, SampleQuantityMode.FiniteSamples, Totalechantillons);

    Create the mult-channel drive
    analogReader = new AnalogMultiChannelReader (analogReadTask.Stream);
    analogReader.SynchronizeCallbacks = false;

    pulseWriterTask = new Task ("pulseWriterTask");

    Creating a digital output channel that provides the trigger to the U/S system
    pulseWriterTask.DOChannels.CreateChannel (initParams.AddrUsTrigger.PortLineAddress, "US trigger", ChannelLineGrouping.OneChannelForEachLine ");
    pulseWriterTask.Timing.ConfigureSampleClock ("/ SampleClock/AI/Dev1", initParams.SamplingRateHz, SampleClockActiveEdge.Rising, SampleQuantityMode.ContinuousSamples, samplesPerPulse);
    pulseWriterTask.Stream.Buffer.OutputBufferSize = samplesPerPulse;
    pulseWriterTask.Stream.WriteRegenerationMode = WriteRegenerationMode.AllowRegeneration;

    pulseWriter = new DigitalSingleChannelWriter (pulseWriterTask.Stream);

    pulseWaveform = new DigitalWaveform (samplesPerPulse, 1, DigitalState.ForceDown);
    pulseWaveform.Signals [0]. The States [0] = DigitalState.ForceUp;

    analogReadTask.Control (TaskAction.Verify);
    pulseWriterTask.Control (TaskAction.Verify);

    From reading:

    analogReadTask.Start ();

    Start writing the digital pulse, however it will not start
    until the AI/SampleClock begins, so implicitly synchronizing the two tasks
    pulseWriter.WriteWaveform (pulseWaveform, true);

    analogReader.BeginReadWaveform (Totalechantillons, readerCallback, analogReadTask);

    Result (should be a sinusoid from end to end)

    Always seems to solve these problems, shortly after their validation.

    The problem has start the digital task AFTER the analog task. In the small delay between the two lines of code running, read analog had already begun, and so some of the impulses of the AI/SampleClock were missed by the task. The order of departure between the two tasks of switching solves the problem.

  • read into the buffer variable published network shared

    I use a shared variable that is published in the network buffer to write data to an RT target and read data buffered by the host application.

    I followed a different behavior regarding data buffering using Variable vs reading read the shared Variable node.

    There is no problem the shared variable node read but using the results of reading variable function of loss of data, such as access without alkaline reserve. I can read only some of my data values.

    I see no difference in access in the buffer in LV2009 help.

    against

    Any help is appreciated

    Christian

    Hi Christian,

    The behavior you describe is because the client side PSP buffering is not applied to the Variable API shared in LabVIEW 2009.  It was a design decision, but eventually, we hope to include this feature in a future version of LabVIEW.  This bug here as you pointed out is the lack of documentation for it.  Corrective Action Request # 202159 has been filed for this issue.

    Let me know if you need assistance working around this issue.

  • Leak memory in real time caused by VISA Read and timed loop of data nodes? Is not supposed.

    In collaboration with LV 8.2.1 in real time to develop applications that monitor or emulate computers on bus RS-422.   The following screenshots have been taken an application that monitors a transmission of 200 Hz.  After a few hours, the PXI station would break a range impressive messages angry... most involving something about memory loss.  After much hair pulling and passing money, my partner has discovered while looking at the available memory on the controller of loss of memory occurred at each loop containing a VISA read and propagation of error using the data nodes (see Leak.jpg of memory).  He concluded that if he went to the propagation of the error to the regular old shift registers, then the available memory was rock-solid.  (has the Leak.jpg of No memory)

    Any ideas of what could be the cause?  Do you see not any problem with the way that we code these kinds of loops?  We always strive to optimize the way in which we use the memory on our urgent requests and VISA readings and DAQmx bed give us the heartache more than ever, we are able to allocate memory for these screws some tips?

    Hi thisisnotadream,

    This problem has been reported, and you seem to be exactly reproduce the conditions required to see this problem. This was reported to R & D (# 134314) for further investigations. There are several possible solutions, of which one is the one you have already found the wiring error directly in the loop. Other situations which give rise to no memory leak are:

    1 if the bytes of the property node port is not there and has read lies in each iteration and time-outs resulting are ignored.

    2. If the structure of the deal is gone and just blindly check the bytes to the port and read each iteration.

    3. If the timed loop is transformed into a while loop.

    Thanks for the comments!

    Kind regards
