• I am using IVI step switch in TestStand 4.1.1 and also try to call the Actions of LabVIEW using IVI

  I use IVI pass the stages and steps of IVI DMM TestStand 4.1.1 and then I have an Action step that IVI spend IVI DMM and features.  The problem I have is that if I run the VI in LabVIEW bear only functions without any error, if I run of TestStand without all previous calls to switch IVI or IVI DMM it works also, but if I run the sequence with a step of IVI teststand pass first I get the following error:

  Initialize IviSwtch with Options.vi
  The primary error: unknown status code (Hex 0xBFFA4001)

  «"" "String of full appeal:»»"»
  Initialize IviSwtch with Options.vi

  -1074118655; User-defined error code.

  I remember there used to be a problem with the steps of the IVI and IVI running LabVIEW, does anyone know if this problem has been corrected?

  Other ideas would be appreciated.

  Hello Kevin,

  It is a question of trying to open more than one session to a particular device of IVI.

  Here is a knowledge base on the issue. I found this knowledge base by searching '1074118655' or 'TestStand IVI Action no' to ni.com.

  Please let me know if you have any other questions.

• stop the script with labview

  Let's say that I run a script using the "DIAdem"run script.vi"due to the demand of the user.  Later, the user wants to cancel because it took longer than expected.

  How to stop the script using labview tools?

  Jim

  Hi Jim,.

  It is possible, but not in the way I think you hope.  I don't know any way to end a VBScript script running in the DIAdem of the 'outside '.  If you have been watching DIAdem you could hit the key, but a subsequent application of LabVIEW goes in "Script stack" of DIAdem and does not run until the first VBScript happens naturally.

  Of course, you need to run all your calls of LabVIEW to Sophie in an asynchronous way, or does not.

  If you can do is set up each VBScript that you think you might want to abandon to periodically query a global variable of tiara, say "B9" and end of inside the VBScript if B9 = TRUE.  LabVIEW DIAdem (ToCommand) command interface will stack Script tiara, but variable interface of LabVIEW DIAdem (ToDataSheet) does not work.  If you can "poke" during execution of the first VBScript variable B9 of LabVIEW and influence its behavior, but only if and when this VBScript uses this variable (B9) get bitten.

  Of course, none of this helps if your VBScript is busy waiting for a simple VBScript command to run, and it helps only if your VBScript executes several activities, among which it can interrogate the variable (B9).

  Hope that helps,

• The trio of Labview, card PT and Basler A - 610 camera F gray

  Hi all

  I'm doing a project on the merger of the camera with a PH d teacher. As I am the research assistant I can make all preliminary ups. in any case its very annoying that I'm stuck on the first step. Which is simply the video detection from one camera on LabVIEW. The equipment I use is an A-610f "basler" firewire camera, a gray PT 1394b PCI Express Card (http://www.ptgrey.com/products/firepro/index.asp).

  The basler connects with gray map of PT via a firewire cable. Now that the card is not an OR product it is not shown in the MAX I just need to get the video of LabVIEW, but I don't know where I have to access the camera from.

  I'm using LabVIEW 8.2.1 and I Vision Assistant and Toolkit Vision and Motion installed on my machine. In addition I just download demo version of the Vision Development module as well. Again for the clarification that I just need to acquire video from my camera.

  Finally ive it resolved myself!... .. The main problem was with the son of the late himself! .. I was amazed when gray pt was charging me $75 for a firewire cable because it was available in my country of origin for Rs 250 to the free market. I bought one and then started five days of immense struggle and re struggle. Finally, I thought that ive tried all means why not give it a last try and buy the original cable. I borrowed it from a firm surface and 'khatttaaaaaaak'... it works! Although I had to install the SDK of basler to view the video stream. Once the entrance to the camera was visible on the SDK. It was smooth then leave. IMAQ Max was able to detect the camera. The right software was all that remained to be installed. Once the right software has been installed using MAX. It was all great. The power of the camera was visible on max as well. I opened the Vision Assistant and he began to take the camera feed as well.

  I decided to transfer to another device in the PCI card and hooked to another quality firewire cable. The repeatition of above process ensures that the camera is fed was visible on SDK, MAX and Vision Assistant. Although permitted high-speed bandwidth continues to be a problem. Another problem which forced me to bite the nail outlet there is over and done.

  Moral of the story: use the original substance

  Yes, you're right. This is the traditional DAQ VI.

  Install traditional DAQ 7.4.4 (WXP or W2000) and check that you activate LabVIEW support when configuring the installation program.

  PS: The LabVIEW 8.5 and traditional DAQ are not supported under W7. See here (OS<-->LV) and here (DAQ<-->LV).

• The call of the TestStand of LabView modules

  Hello

  I have some dllmodules developed to be launched from TestStand and so the methods require a context of sequence as in param.

  But now I would call these modules on a computer without TestStand. I thought the call of LabView but is it possible? I do not have access to change the modules.

  You can use the TestStand Deployment Utility, located in the TestStand menu under Tools-> deploy the TestStand system

  In the TSDU, you can create an installer to deploy a workspace TestStand and tab of Setup options, you can even choose to include the TestStand engine in the installation program.

• How to change the time timestamp labview at the UTC time

  Hello

  I have table of database in UTC time field.i select and insert data in the database table based on labview timestamp controll.

  1 1450422341 123 kumar

  mock 2 786 1450421623

  the era of labview is difference from UTC time. so ADD this second 2082844800 at the time of labview that it will work for selection quary but time insert is not a job.

  Here's how to convert a timestamp of LabVIEW to a timestamp of Excel (OLE).

  

  Red the explainiation down and I'm sure you can figure out how to change it to get the party time you need.

• When I change the setting by LabVIEW on my device, I see change on the monitor of the device?

  When I change the setting by LabVIEW on my device, I see change on the monitor of the device?

  This question should be addressed to the manufacturer of the device. From your previous posts, I guess you use GPIB or serial. If the unit has received the order, the manufacturer should be able to tell if no indicators on the device to update when the order is received. Based on my experience, however, the device indicators will most likely update on receipt of an order successfully.

  Someone at - it experience even?

  Thank you

  Rajamodol

  Dear Rajamodol,

  VeriStand gateway creates a TCP/IP communication channel that
  facilitates communication with the VeriStand engine on the network.

  So if you are running a project on a desktop PC, gateway VeriStand initiates the
  VeriStand engine. If you run a project on an RT target, the VeriStand
  Bridge synchronizes with the system definition file that is running on the
  Target of RT.

  If you set the gateway VeriStand "localhost".

  Kind regards

• LV load error code 9:VI version (13.0) is newer than the version of LabVIEW (11.0)

• Call the function in LabView from a DLL, and then access the global variable of DLL

  I've created a DLL in LabWindows with a function and structure.  I want to call the function from LabView and then access the overall structure.  I am able to call the function in the DLL with a "call library function node" and has access to the return value, but I can't understand how to access the overall structure.  The structure is declared in the header DLL with __declspec (dllimport) struct parameters file.

  Is it possible to access this structure without using the library of network variables?

  My guess is that you need two bytes of padding after "in_out" and another to two bytes of padding after "anin."  The reason being that ints are 4 bytes, and most of them C compilers will align on 4-byte boundaries.  The struct will naturally start to such a limit (in fact, in Windows, it will probably start to an 8 byte boundary).  If you then count bytes in your structure, you are 70 byte after "in_out."  70 is not divisible by 4, so you need 2 bytes more to reach the next 4 byte boundary.  You can also you could reorganize your struct so that "anin" follows "in_out" and this is probably the best option if it won't cause you other problems.

  Unlike most C compilers, LabVIEW compressed structures as closely as possible, without filling.  I don't know enough about the history of LabVIEW and internal parts to explain the reasons and to do this performance penalty, but, as choice of LabVIEW "endianness", it is probably a remnant of the first versions of LabVIEW that were running on the Mac.

  If for some reason you want to force your C struct to match package LabVIEW, you can use the #pragma pack (x) directive, but I wouldn't recommend that here because you can control the C and LabVIEW.

  EDIT: in the cases where it was not clear, add padding to your cluster of LabVIEW, insert appropriate size or items at the place desired in the cluster.
