LV RT - system configuration: Find_Systems.vi - error "-2147220620."

Hello

I have problems with my code running on my cRIO in run as startup mode, but not in development mode. See extracts attached code. Copy the following code does throw some error when I run my development system, but when I deploy on the cRIO, my log file shows an error:

-2147220620, source: nisyscfg.lvlib:Find Systems.vi:1750001
«"" "String of full appeal:»»"»
nisyscfg.lvlib:find Systems.vi:1750001

I looked at the error and it corresponds to "a specified expert is not installed."

I made sure the cRIO has every possible thing installed and up to date, if this isn't the problem. I also forced the nisyscfg.dll to be included in the support directory and the error persists.

I ran the VI of Experts get so to get these:

mcSysApi Motion system API Expert 14.0.0

nor-1588 OR-1588 2008 1.0.3

NEITHER nor-rio-RIO 14.0.1

Neither visa NOR - VISA 14.0

niimaqdx NI IMAQdx Sysapi Expert 1.0

nisyscfg Configuration system OR 14.0.1

nitsf NO time Sync Framework 14.0

series NI - Serial 14.0

XNET NOR-XNET 14.0

It's the second time, I ran problems where there is a discontinuity between my code running on the cRIO only and it works in development mode.

Does anyone have suggestions for this problem?

Thank you

I may be something, but I do not have 100% tested solution yet. If I run the VI once RT has had time to sit for a bit, it doesn't throw the error. This leads me to believe, the cRIO had not fully initialized at the time I called the VI. I think it is a bug on a part of NOR, because all the libraries, etc., must be charged at the time that runs the code in real-time...

in any case, I made a loop trying over and over again (max 60 seconds) until no errors are oputput and it seems to work. It takes about 30 seconds (from cRIO startup) to error out not well.

I have tested in my complete application now and will report back if all goes well.

EDIT (follow-up): it worked! I guess that there is not much of a fix, but more than a workaround. It takes almost exactly 30000ms each time for no error.

Best,

    I tried the following things so far (in that particular order):
    -Load BIOS default
    -Flashed the BIOS with the latest version of the BIOS (2.80) for this type of model
    -Reinstalled windows with HARD drive format

    All the these did not work.

    I saw the same message appearing on several places on the internet (on different laptops with a Phoenix BIOS in common), but so far I have not been able to find a working solution.

    It might me a hardware problem, but all devices (vga, soiund, lan, wifi, usb, hdd) seem to work perfectly under Windows, so this does not seem the question). Another solution that is mentioned in some forums, replace the battery. But because the phone keeps time correctly I don't think it's the case either.

    Hello

    The POST (power on self-test) BIOS checks and detects errors on the motherboard.
    I think it has something to do with the hardware on the motherboard problem.
    I doubt that you can solve this if update of the BIOS and the BIOS default settings didn't change that.

    What to say; I think that the technician of the ASP should run tests to check what's wrong or what cause this I think it is question of s mobo.

  • Computer laptop Gateway does not load windows Vista, reads configuration data read error: System.

    OK a friend knows me to fix his laptop. Apparently what she was experiencing major problems, so he erased the disc and tried to reinstall Win Vista from disk. Will not work. I can get to where you can choose a partition to install the operating system to, and it says: Windows cannot find a system volume that meets its criteria for installation. My friend says he has just tried, form disassemble the computer an audit of all the parties to try ALL the different options during installation, as well as the options for the BIOS. Any ideas people? Here are the approximate specifications, because the owner has not been able to get the computer working for awhile:
    4 GHz, 4 GB RAM computer Gateway laptop, 2006, Phoenix TrustedCore, and a string of other interesting info that appears on the first screen of the error:

    I'm not very tech savy and I'm not the owner of the PC, so I don't know all about it so go easy on me :).

    If your friend tried to reinstall Windows by using the defined gateway recovery disc (and this is the best way) and this recovery fails, the laptop has hardware problems. Disassemble laptops is a fickle business at best and while it sounds like the hardware problems started before your friend did this, it may have put the nails in the coffin of the laptop to take apart.

    At this point, you can try troubleshooting hardware or your friend can take the laptop to a competent professional (not a type of BigComputerStore/GeekSquad of the place). However, if the laptop has had hard use, your friend must remember that a cell of 4 years with major hardware problems probably won't be cost effective to repair.

  • the API system configuration error 1097 and freezes

    I used successfully the API system configuration to detect and read information on a PXI chassis.

    But now, when I try to initialize and collated all information using a simple VI, the system returns error 1097 and crashes before the end of the VI.  Based on that the stop button does not work and I have to either soft or hard reboot the machine.

    I have attached a screenshot of it in a frozen state and error, like a report of what is installed on my system.

    The only thing I can think has changed since this last worked has been upgraded my MAX and other pilots from 5.5 to 14.0 and then the latest version as of today.

    It is usually the generic error, which means that some external code access violated the integrity of the system and the memory is likely to have been corrupted in the process. Since it is a NI API system AND it seems to have worked before, I guess it's not a bad disigned call library node, but a form of bribery in external code library itself which implements the API of the System Configuration.

    Reinstalling may solve the problem.

    Hi Alaa' Kabbani,.

    1. did you of recent changes made to your computer?

    2. which antivirus app do you use?

    3. What is the brand and model of your computer?

    I suggest to follow the steps below and we update on the State of the question.

    Method 1: Disconnect any new hardware

    If you have recently installed a new hardware device, the necessary driver so that the material can not be installed or the driver may be damaged or incompatible. To determine if this is true, follow these steps:

    1 unplug the appliance.

    2. restart Windows XP.

    If Windows XP starts successfully, there is a driver problem with the new material. Contact the manufacturer of the device for drivers updated to the device or to learn more about known hardware issues, so that you can reinstall the device.

    For information about how to contact the manufacturer of the device, refer to the Microsoft Web site at the following address:

    http://support.Microsoft.com/GP/vendors

    (http://support.microsoft.com/gp/vendors)

    Microsoft provides third-party contact information to help you find technical support. These details may change without notice. Microsoft does not guarantee the accuracy of this third-party contact information.

    If this method resolved the issue, you are finished. If this method does not work for you, go to method 3.

    Method 2: Disable automatic reboot in case of system failure

    If the system reboots continuously, do the following:

    1. reboot the computer.

    2. as the computer restarts, press the F8 key repeatedly until you see the Windows Advanced Options screen.

    3. use the arrow keys to select disable automatic system error rebootand press ENTER.

    4. If you receive an error message, follow these steps to search the Microsoft Knowledge Base for useful information about the error message:

    a. copy the text of the error message.

    b. visit the following Microsoft Web site:

    http://support.Microsoft.com

    (http://support.microsoft.com)

    c. type the text of the error message in the Search box, and then type the name of the product you are using, for example "Windows XP".

    d. click on Searchand try to find an article that will help you solve your problem.

    If this method worked, you have resolved the problem of your computer restarts continuously. However, you can continue to troubleshoot driver problems. See the "Symptoms" section again and determine which method to use to solve the problem.

    If this method worked, you are finished. If this method does not work for you, please try Method 3.

    Method 3: Use the known last good Configuration feature

    If you can start the computer successfully, you can use the known last good Configuration feature. This feature uses information that was saved the last time that you shut down the computer before the problems started. This feature allows to restore your registry settings and drivers to the previous information.

    If you are not completely sure what that means, don't worry. None of these reviews will damage your computer. However, you should be aware that if you do this, any changes made to your computer after the date of last known good configuration will be lost.

    If you have recently installed a driver and know a configuration problem, this method will probably work for you. Unfortunately, this feature does not solve the problems caused by missing drivers or corrupt or files.

    To use the last good known Configuration, follow these steps:

    a. restart the computer.

    (b) that the computer restarts, press the F8 key repeatedly until you see the Windows Advanced Options screen.

    c. use the arrow keys to select last good Configuration known (your most recent settings that worked), and then press ENTER.

    d. If you are prompted to select an operating system, use the arrow keys to select the operating system and press ENTER.

    If this method worked, your computer is restored to a good working state. You still have to investigate on what caused this problem. To do this, please see the "Next steps" section for troubleshooting resources more.
