RT Scan interface mode

hi guys 
i want to do a scan mode for a CompactRIO and my friend has not the hardware (cRIO) so i want to know if the Scan Mode requires the hardware or not and if it's possible to make a virtual cRIO plz help help help 

Hello,
You can use a certain level of “simulation” capabilities…more like setting up off line devices as explained in Document ID: 3W6EFRLX.
Unfortunately in Scan mode these features won’t help much if you truly want to simulate the behavior of your program but if you only want to start building the application and preparing the VIs before getting the hardware then it should help you get started.
Also, you can try to work around the limitation by running your RT VI on the windows Host and the module related logic on FPGA with simulated IO.
I hope this helps

  • Scan interface mode erreur -805

    Bonjour,
    Je suis débutant de système Compact RIO. J'ai quelques questions sur le scan interface mode.
    Le matériel que j'utilise est 
    le contrôleur cRIO-9012 et chassis cRIO-9101 intégré
    une carte AI 9205
    une carte DIO 9401
    Je voudrais utiliser le scan interface mode pour comprendre le fonctionnement des cartes, dans le FPGA interface mode, ça prend du temps pour la compilation.
    Le chassis ne supporte pas le scan interface mode, alors je configure les 2 cartes individuellement en utilisant les I/O variables. Ensuite je crée un VI tout simple pour lire la tension de la carte AI. J'obtient une erreur -805 : Timing source ,synchroniser avec le moteur de balayage.
    J'ai vérifié aussi dans MAX, le soft  NI scan Engine est bien installé.
    Quelqu'un pourrait me dire d'où vient ce problème?
    Merci d'avance.

    Erreur
    -66205 peut être un résultat de l'erreur précédente, mais aussi parce que les
    variables partagées ne sont pas déployées (correctement). 
    Comme expliquer dans l'article proposer par « speleato »
    (http://digital.ni.com/public.nsf/allkb/122E971F52F​D081A86257500007A046C), vous
    devez compiler et exécuter le « Blanc VI » du FPGA enfin the déployée la
    logique nécessaires pour le « scan mode », utilisant la fonction « Open
    FPGA VI Reference » dans le « test 9205.vi ».
    Le moment
    que la logique est déployée, l'erreur doit être disparue.

    Error -66205 can be a result of the previous error, but more
    likely it is because the shared variables are not deployed (correctly).
    As explained in the article refered by « speleato » (http://digital.ni.com/public.nsf/allkb/122E971F52F​D081A86257500007A046C),
    you need to compile and execute the « blanc VI » on the FPGA target
    to deploy the needed « scan mode » logic, using the "Open FPGA VI
    Refernce" function in the "test 9205.vi".
    Once this is done, the error should have been gone.

  • Crear PWM con CompaqDaq o CompaqRIO (Scan interface mode solamente)

    Que tal amigos.. Estoy realizando un proyecto en el cual es necesario enviar ya sea digital o analógica una señal PWM pero a altas velocidades.Requiero que la frecuencia máxima sea de 200kHz. Lo he intentado de diferentes maneras pero lo mas veloz que he obtenido son 500Hz. Tambien dispongo de un CompaqRIO 9074 y si pudieran ayudarme de igual forma con este chasis estaría de lujo, solo que también lo he intentado pero no me da los resultados deseados y mas aun porque no estoy familiarizado con la programación en FPGA solo con scan interface mode.
    ¡Resuelto!
    Ir a solución.

    Que tal Reno32
    Trabajando en Scan Interface:
    Dentro de los ejemplos de LabVIEW, viene un proyecto que podemos utilizar como referencia para trabajar con salidas PWM en Scan Interface. Dentro de LabVIEW, seleccionamios Help >> Find Examples y en la pestaña de Search buscamos por la palabra 'PWM'. Hay un proyecto en particular que me gustaría que revisara, el cual se llama "NI 94xx - Pulse Width Modulation - Scan Mode.lvproj". Particularmente este ejemplo lo podemos utilizar para trabajar con un chasis cRIO 9074 y cualquier modulo NI 94xx. Dentro de este proyecto, las salidas digitales de un modulo NI 9401 se configuran como PWM. De hecho si damos click derecho sobre el modulo con el que estemos trabajando, y vamos a Properties, podemos seleccionar que queremos trabajar la salida digital como PWM, y podemos seleccionar la frecuencia a la que deseamos generala. 
    La máxima frecuencia que podemos alcanzar, trabajando en Scan Mode es de hasta 20 kHz. Dentro de este proyecto, viene el código utilizado para trabajar con estas salidas PWM, que quizá nos pueda servir de referencia. 
    Trabajando en FPGA:
    Ahora bien, si deseamos alcanzar velocidades más altas, esto lo podemos lograr bajandonos a configurar el FPGA de nuestro cRIO. De igual forma, dentro de Help >> Find Examples, buscando en la pestaña Search por 'PWM', hay un proyecto titulado "PWM Generation.lvproj" el cual nos puede servir de referencia para configurar con salidas PWM configuradas directamente desde el FPGA. De igual forma, le comparto el 'Getting Started with CompactRIO and LabVIEW', en donde viene una sección de 'Creating a PWM Loop', en donde vienen los pasos sobre como crear una salida PWM configurarada directamente en el FPGA.

  • How do i reset a counter in crio scan interface mode

    Hai,
         I am using cRIO 9104 with NI 9421(DI SINKING) module for my counter application in scan mode.
    I have a doubt that how do i reset my counter previous value when my system is in idle mode(i.e stable mode).I tried to use a timeout in property node, But i am not able to put a timeout in my code ,herewith I have attached the printscreen of my program.You can see the timeout option is in hide mode.Any other option is there to reset a counter.Kindly solve this problem and let me know the details.
    Thanks and Regards

    You need to get a refnum for the module.  The simplest way to do this is to drag the module in the project onto your block diagram.  It will drop a refnum constant for the module.  You will find all kinds of useful properties and methods on this refnum.  In this case the refnum is of a class named "SD Module" (where "SD" stands for "Specialty Digital") and it has a method on it for resetting counters.  See the attached screenshot of the block diagram.

  • Scan Interface

    Is it possible to configure cRIO 9102 Chassis under Scan Interface Mode? I am planning to use to 9012 Controller.

    Hi Cooldude,
    Thanks for your post and I hope your well today.
    The requirements for Scan Engine for cRIO is, 
    Software:
    Real-Time Module 8.6+
    NI-RIO 3.0+ with Scan Mode Support installed on cRIO
    Hardware:
    The majority of cRIO hardware does support Scan mode; however, the following do not:
    Controllers: NI 9002, and NI 9004
    Backplanes: NI 9101, NI 9102, and NI 9072 
    THEREFORE
    You cant.
    BUT
    To use the 9102 you can do the following trick,

  • Scanning interface with epaon printer

    I have a WF-7520 & WF-4530 & WF-3640 All-in-One Printers. I had been using the WF-4530 for scanning using Adobe Acrobat X, version 10.1.12. The combination of Adobe and WF-4530 worked perfectly for several years. Then the WF-4530 started profusely leaking yellow ink (a product defect) and I replaced it with the WF-3640. The WF-3640 and the WF-4530 does not interface with adobe like the WF-4530 did. A lot of the interface is greyed out and I get the message "WIA Scanner Driver might face problems using 'Hide Scanner's Native Interface' mode. Switching to 'Show Scanner's Native Interface' mode.
    I have searched through the manual, when on line and to youtube and can't find information on how to fix the interface problem. Can you help me?

    How could anyone "Be Well" with  your response/solution? Acrobat does not scan? Well that's obvious. But something is really screwed up  here and I also have this same stupid problem. And for  well over a decade I've used various versions of Acrobat  on numerous scanners and printers, and there are basic requirements set for communicating scanning and printing for both Acrobat and scanners and printers. Are you telling  this person that Adobe software has no responsibility to recognize scanner or printer interfaces  either with a USB or wireless? This whole interface issue should be a no-brainer and apparently Adobe is the problem!

  • FPGA Analog Input with Scan Interface

    Hi all,
    I am rather new to the FPGA Module and have a question concerning analog sampling.
    Before, I used a cRIO in scan mode to perform following tasks:
    A state machine on the host PC performs one task after the other, e.g: output a voltage, run a stepper motor (with the NI 9512), Acquire voltage signals using the scan engine mode, logging data ; next voltage, next stepper position, next measurement, logging to the file,.... and so on.
    Now, I want to perform the same task, however, with a sampling rate that exceeds the performance of the scan engine. So I think I need to jump to FPGA Mode.
    The question is: Can I "mix" the measurement in FPGA while running others tasks of the state machine in scan mode? In more detail, I only "need" the FPGA Mode for the data acquisition, however, for running the stepper motor the Scan mode is perfectly fine and somewhat easier.
    One idea of mine was to create a fpga-vi on the target that acquires a certain amount of voltage samples and sends it to the host. Now, could I run the state machine as I did before, just for the state "voltage measurement" refer to the fpga-vi on the target and get the data?
    Thanks for any hint,
    Jack

    It would be best to not mix the scan engine and the FPGA.  Yes, you can do hybrid mode, but it uses A LOT of your FPGA resourses.  You can still use the state machine in your host, but you will just need to change the commands slightly to use the FPGA interface instead.  Use a DMA FIFO to send your analog data to your host to be logged.
    There are only two ways to tell somebody thanks: Kudos and Marked Solutions

  • Windows 8, "Installer Interface Mode Not Supported"

    I am getting the "Installer UI Mode Error", "Installer User Interface Mode Not Supported"
    I have tried compatibility mode, as this worked on my previous laptop Windows 7 and XP sp3, but when I "Test Program" and the InstallAnywhere Self-Extractor completes install prep. to 100%, there is no response.

    Is this a very, very old program?  What program? 
    Have you done an Internet search to see if anyone else has gotten it to install?
    Have you tried running it As Administrator, in addition to the compatibility modes?

  • Error 2147138480 in Set Scan Engine Mode to Actif

    Hi all,
    I'm fighting in front of this error which occur and does not want to go away (even after trying everything)...
    The error (-214713840) is happening when trying to set back the Scan Engine Mode to actif.
    It says: "The slave device could not be found. The positional addresses within the LabVIEW project are inconsistent with the actual network topology. [...]"
    I was trying to program the detection of the loss of a CompactRIO chassis when this error first occurr.
    I have 2 CompactRIO "EtherCAT" connected to a RT computer.
    Thanks for all the help or suggestion you can provide me ;-)
    Cheers,

    Hi Laurent,
    I don't know if your problem has been solved but I prefer asking.
    Are you sure of the error code you encounter ? I don't find it in the manual or other places.

  • Sr400 scanning gate mode

    Hello Forum,
                       Some of the problems I've encountered using the sr400 gated photon counted have been commented on here before (e.g.. It often hangs up while waiting for the RSI, and that this can be more or less solved by removing this request.)
                       A problem that noone else has discussed is using it in scanning gate mode. I have attached two programs one with the RSQ and one without) that ask the counter A to scan. As I understand from the manual, this means that for every count period the delay before the gate opens should increase by a user-determined increment. 
                         There is first a question of stability, in that the program doesn't always work. Sometimes the photon scnnaer scans, sometimes it doesn't. However, on the occasions that it does tell me it is scanning, I see no evidence of this in the results. Since I'm scanning through a modulated signal (a square wave), the scan should reproduce this result. Instead, all I get is a straight line.
                           If one has the time, can they look through the program and tell me whether there is a serious issue with it or whether the problem should be put down to the age and stability of the photon counter. The programs are a lightly modified version of one posted by a forum easier, which apart from the problem with scanning, works more or less okay.
    Thanks,
                L

  • Please explain Virus Scan Interface?

    When we run virus scan on SAP server CPU utilization go high ,SAP team advice us to disable the virus scan.
    They told us that they Virus interface in SAP. My question how it work is it ok not to install Antivirus software’s on SAP server

    Architecture of the Virus Scan Interface & help me in defining Defining Scanner Groups
    The structure of the Virus Scan Interface allows you to combine different products, systems, and platforms to scan your applications for viruses. This is possible, since SAP provides a certified interface for the virus scan products of other vendors.
    The partners’ virus scan engines can, for example, have completely different architectures.  However, by integrating an adapter using a proprietary connection, any partner can, however, connect any existing virus scan product to the virus scan interface.
    On the SAP side, different VSILIB layers are used to include the ABAP and Java worlds, and to deal with platform dependencies (of operating systems and processors, that is, 32 or 64 bit) in the integration of the virus scan interface.
    Use
    A scanner group combines multiple virus scanners of the same type to allow load balancing. Since you select the virus scan server using the scanner group when maintaining the virus scan profile, you must assign each virus scan server to a scanner group.
    Maintain a scanner group for each product class of virus scanners that are connected to the system using the virus scan server. If you include your own virus scanners with the BAdI VSCAN_INSTANCE, create a scanner group for each implementation of your own scanner and identify these as BAdI implementations.
    You can store configuration parameters for each scanner group. These are divided into initialization parameters and scan parameters:
            Initialization parameters are transferred to the virus scan server when it is started, and are required to be able to start the virus scan server. If you use the Business Add-In, these parameters for the method of creating the scan instance are transferred. The parameters contain, for example, the path to the virus signatures.
            Scan parameters are transferred for each scan process and control the behavior of the individual request, such as yes/no for activating the scanning of macros.
    For information about which configuration parameters are required or supported by the product that you use, see the documentation for the product.
    SAP does not deliver any scanner groups.
    Procedure
           1.      In the Implementation Guide, choose (IMG) SAP Web Application Server ® System Administration ® Virus Scan Interface.
           2.      Choose the Execute option next to Define Scanner Groups.
    The screen View: Change "Scanner Groups": Overview appears.
           3.      Choose New Entries.
    The screen New Entries: Overview of Added Entries appears.
           4.      Specify the data for the scanner group.
