• Find VISA resources

  I have trouble finding VISA resources properly. I have no problem detection instruments that are connected on the GPIB, but after that they have detected once LabVIEW is convinced that they are there for ever more, even if I unplug and disconnect the device! The only way that the list of the connected instruments is reset completely out LabVIEW and restart it. Why is this?

  I'm using LabVIEW 6.1 (but who can not make a difference) and I attach a VI with two ways to detect if one of the four possible instruments are connected. The Subvi is used to give a command to one of the instrument, and it is able to return an error if the instrument is not connected, regardless of the situation. How can it detect the instrument as expected, but the other methods not?

  In this VI, I need detect how much, if any, and that out of four possible instruments are connected. Simple, but amazingly difficult!

  Any help please?

  Well, now that you say is starting to make a little more sense. I misunderstood what you were asking before.

  Help: "automatically close your left VISA open sessions by the application when the first level VI becomes idle. This check box is cleared by default. "This was added at some point (don't remember when), and the default value is True. It caused a lot of sorrow and complaining from users (I was a), so NEITHER changed the default value false.

  As Dennis has pointed out, there is a distinction between the resource and the instrument. When you perform an initial analysis resources will be created. There is no mechanism that automatically detects that an instrument is no longer there. In fact, when you scan for instruments of MAX, she sends * IDN? queries to find instruments. So, you must check for the presence of an instrument by actually trying to talk to her.

• visa resource name function

  Hi good day to everyone!

  I am a beginner to LabVIEW, and currently I'm testing on a single project.

  Store device data in Server series of STS (which has 16 com ports).

  But I need to use 7 series STS server com ports. I need to read that data 7 com ports and save in a file.

  Each com port has a different function (for example the reading of data or display).

  My question is,

  (1) VISA resource name operation function for 7 com ports at the same time to a VI?

  (2) how can I choose different com ports to different functions?

  Kind regards

  Control of resources of e/s of VISA will show you all the com ports you have on your computer.

  So you just need to make 7 copies of that control and the value of each of them to another com port and use for each VISA entry and read the series of functions that you do.  (Have you looked in the example Finder to get examples of serial port?)

• A control "VISA Resource Name.

  In LabVIEW, there is a control "VISA Resource Name" which lists all the VISA resources, is automatically updated when devices are plugged or not plugged in and has a navigation feature.

  With CVI, you can use NIDAQmx_NewDeviceCtrl () on a control of the chain, but it lists only the DAQmx resources.

  There is another function that I can use to have all resources VISA listed?

  Hey Vix,

  It seems to be the only solution. Here you will also find an example.

  I hope that helps!

  Bye,.

• VISA resource name strings

  Hello

  I have a control "VISA Resource Name" on my front, according to the guidelines of the attached screenshot, which should automatically fill with the names of all the VISA resources that the PC can see.

  Is it possible to get a picture of these names as strings (via a property node, or other) programmatically?

  Thank you very much

  Dan

  In the schema click Instrument of e/s > VISA > VISA advanced > VISA find resources. This VI returns an array of strings. You can type cast the string in a resource VISA type.

• PXI-4070 appearing does not in the locations of SMU-1075 16 & 17

  Hello

  I have an SMU-1075 with the help of a remote SMU-8370/PCIe-8371, 4 SMU-6363, SMU 8-2351 and PXI-4 4070 s. The PXI - 4070 s are required to be plugged into hybrid slots (2-5 or 15-18). To maximize throughput, the 4070 s are plugged into connectors 4 and 5 and the other 2 are plugged into the 16 & 17 slots so that the DMM is divided to the use of 2 different PCI to PCI bridges. The issue I see is that the 4070 s 2 plugged into slots 16 & 17 are not displayed in NI MAX and in the Device Manager, display an error (see photos). I can see and use all other modules in the chassis, including the other 4070 s 2.

  I have 3 other machines running in production with a configuration almost identical, the only difference is that the other machines use a PCIe-8372(or maybe an old model of the PCIe-8371?) The main difference is that the cards in the older machines have 2 ports but the model # is not projected on the cards so 8372 is a guess based on the installation booklets) host controller. The PCs are identical in all 4 machines: industrial Advantech, WinXP sp3, Intel core 2 Quad, 2 GB of RAM.

  If I remove the PCIe-8372 among the machines to work and install it in the machine, with that I have problems, I can see and use all of the 4070 s so that we know that the PXI chassis and 4070 s are very good. I also tried all sorts of versions of different drivers and drivers uninstalled/re-installed several times as well as the solution provided in this post of 2011: http://forums.ni.com/t5/PXI/PXI-4070-DMM-in-PXIe-1075-Chassis-not-found/m-p/1609804/highlight/true#M...

  I was wondering if anyone else has had problems similar to this?

  OR Support Reference #: 2292623

  It's a strange problem.  If anything, from the 2 to the guest card guest card 1 port should help.  A few things...

  Have you tried the 4070 s 2 Slots 16 and 17 of the 15 to 18 slots?  One of the effects of different host maps is a different interrupt for some legacy interrupts swizzling, and their displacement that will put them on the other 2 lines.  It seems unlikely that the problem.

  Another long shot based on the differences between the PCIe-8372 and PCIe-8371: try to remove one of the panels of the SMU of the system.  Reason: PCIe-8371 requires little storage space.  If we put a needle with how the PC will provide then reduce the requirement will bring the use of net memory to 0 (PCIe-8371 ask 1 MB, which is the minimum no no one can ask any card PCIe/SMU).

  Have you tried the software of BIOS compatibility and the switch on the PCIe-8371?  http://www.NI.com/download/MXI-Express-BIOS-compatibility-software-1.5/3764/en/

• How a cRIO can access remote systems VISA resources?

  I have a NI 9871 RS485 module on an ethernet 9148 RIO.

  I have also a laptop and a cRIO 9073.

  I can access each of the 9871 serial ports on the computer but not the 9073.

  When you try to access it from the cRIO, I get error:-1073807192, VISA: (Hex 0xBFFF00A8) is denied access to the resource or to the remote machine. This is due to the lack of sufficient privileges for the current user or the machine.

  How the cRIO can access the serial ports of the module 9871 on the ethernetRIO?

  Or how a remote access cRIO visa resources?

  Or how a cRIO can have sufficient privileges to access remote resources from visa?

  Thank you for your help.

  LabVIEW 2010 & VISA 5.1 on pc

  NOR-RIO 4.0 and 5.1 VISA & NI 9871 SERIES scan engine support on cRIO and eRIO

  Hi Woss,

  It is possible that your RIO Ethernet has some parameters of active access which is to prohibit the connection to serial ports.  You can change these settings in a position and Automation Explorer (MAX) for your device by going to the device under remote systems, expanding the category of software under it and choosing NI-VISA.  There will be a tab in the right pane of MAX called Options of VISA.  In this tab, select Server VISA > security to access these settings.

  From there, you should be able to add the IP address of the RIO device that needs to access the VISA on the RIO Ethernet server.  Once you have changed these settings, just click on register at the top of the window and allow the unit to restart.  Let me know if that helps!

• How to create names for VISA resources

  Create a VI to interface with a Tektronix Oscilloscope. Tek drivers all use and transmit handles instrument VISA Resource Name to the format.

  Yesterday, I simply plugged a text string with the characters of text on the Tek pilot and it's happy. String = "GPIB::12:INSTR".

  Today, LabVIEW dislikes this incompatibility of format, and I get an error of the pilot.

  My format of the string looks OK, but I have to do something wrong. None of the tools VISA simplty interrogate the device for his VISA resource name. How to do it?

  Thank you.

• VISA resources between the loops with the queue

  Hi all

  I am just be familiar with the queues and the producer/consumer model, and I am facing difficulties to pass data between the loops using queues, including data of the type "VISA Resource Name.

  Indeed, it seems impossible to cable "VISA Resource Name" as an entry of the item in the queue, as an output of the Dequeue item.

  These screws can I always try to convert something of this type can accept? Or should I take a different approach and that one?

  Thank you very much for your help.

• -error with the PXI-4070 107418650 same w/o autorange.

  I have a PXI-1033, which includes a PXI-4070 module in slot 5. I use a version of the scanning of switch with DMM - Handshaking.vi but I changed to read a list of fixed scanning and I have replaced the meter of while loop with a fixed reading of 144 samples.  After the execution of the present VI about 47 times I get this error:

  

  I am NEITHER-DMM 3.0.4 OR-DAQmx LabView 2101SP1 9.3.0f2 and Vista Business 32-bit slot. I use 4 resistance wire and tried both auto and fixed the range with the same results. Before this loop the related single DMM functions is to read resistance readings 4 son and close the DMM. This seems to loop forever without any problem.

  Dozens of times to restart a day gets old fast, any ideas?

• visa resource can't find ports

  Hi all

  I'm having some problems with access to my COM-Ports: they are not only apperar in the drop down "Resource Visa..."

  There should be a USB adapter to series, which has been installed correctly (appears in devices and printers as COM4) and has so far worked correctly with labview on other computers.  Also, I added just a Dev series, but also who is not recognized...

  I've just updated my computer from windows xp to 7 and labview 2011 to 2012 if it is of no relevance.

  Before updating the series on the same computer USB adapter worked very well... (The card series however was not recognized backthen either..)

  I am very grateful for any idea you may have!

  Thank you very much in advance,

  Keksbold

  In MAX, under 'Software '. NI-VISA would be on your hardware driver DVD you got with the distribution of LabVIEW. Or download it (click on the help link at the top of the page).

• How to detect the resource (find) information?

  Hi all

  I'm trying to detect programmatically information resource name for devices HSDIO PXI and PXI-4130.   How can I do?    System DAQmx property does not include these devices, and I can't find a way to convert a resource VISA name in name of resource HSDIO or NI DC PS formats.  I enclose a code snippet that detects resource VISA for a device 6552 name, but I can't seem to figure out how to get the name of MAX the device resource.   Both the niHsdio and the properties of 'name of the resource' OR DcPS requires that you spend a session valid in them need valid resource name andI to make...

  And no, asking the operator to launch of MAX and find the name of the resource is not an option

  Thank you
