knowledge of the limited definition

Hello

I just discovered the following problem with the IDE: CVI provides a nice feature "Go to definition", surprisingly it seems to not always work...

The test scenario: in the call to viFindRsrc (), I tried the following regular expression:

"ASRL? * INSTR {VI_ATTR_ASRL_WIRE_MODE == VI_ASRL_WIRE_232_DTE |} VI_ATTR_ASRL_WIRE_MODE == VI_ASRL_WIRE_232_DCE | VI_ATTR_ASRL_WIRE_MODE == VI_ASRL_WIRE_232_AUTO}.

It did not work as expected so I started debugging; right click on VI_ATTR_ASRL_WIRE_MODE with going to definiton correctly jumped into the right line of the visa.h file.

As expected. However, to do the same thing for, for example, VI_ASRL_WIRE_232_DTE does not work, although this definition is found a few lines below the definition of VI_ATTR_ASRL_WIRE_MODE.

So I thought it could be a typo and cut/pasted the name of constant since the include file, same result.

Somehow, go to definition doesn't seem to work in these cases.

I'm doing something wrong?

Hello Wolfgang,.

ICB does not generate browse info of macros that are not referenced.

For example, if you have

#define MY_MACRO 1

No info browse for MY_MACRO is generated. But if you have

#define MY_MACRO 1
...
x = MY_MACRO;

then browse info is generated for MY_MACRO.

In your example VI_ATTR_ASRL_WIRE_MODE and VI_ASRL_WIRE_232_DTE are part of a chain, no references for these macros.

I assume you are using in your code that does Browse beeing of information generated for her but not for VI_ASRL_WIRE_232_DTE VI_ATTR_ASRL_WIRE_MODE somewere.

  • The limitation does not not as expected in the JMS adapter

    Hello

    I have a BSE consumer (name: ConsumerESB), that retrieves messages from a weblogic JMS queue and routes them to a BPEL (InvokedBPEL) process.
    The queue will get messages in mass 5000 requests at once and I need to implement the limitation to process applications slowly.


    Here's what I put.

    For the .esbsvc map file, I put

    minimumDelayBetweenMessages - 3000 (3 seconds behind should be there between each message)
    adapt. JMS. Receive.threads - 1
    DequeueTimeOut - 3

    According to the above definition, I think, a request must be sent by second and three seconds between two messages.
    But I don't see that past, I think I'm getting something like 4-5 requests per second.

    The limitation does not seem to work.

    Later, I tried the following options:
    (for adapter .esbsvc)
    minimumDelayBetweenMessages - 10000
    adapt. JMS. Receive.threads - 1
    DequeueTimeOut - 10


    (for .esbsvc routing rule) - got - I need this setting for the routing rule esbsvc?
    minimumDelayBetweenMessages - 5000
    DequeueTimeOut - 5

    Now, I see only one application per second.

    Can you please let me know how can I get a perfect delay of 3 seconds between two messages.

    I raised a SR with Oracle and discovered that the minimumDelayBetweenMessages property is only applicable for BPEL and not BSE. Therefore, I created a BPEL consumer instead of a BSE consumer and applied to the property of limitation. It worked.

    SR link is below for reference.

  • Satellite M40-307: accessibility utility does not work with the limited user account

    Hello everyone,

    I have a Satellite M40-307 (PSM44E), and I had a problem with the utility "accessibility", which displays an icon in the notification bar of Windows XP, to inform the user if the "Fn" key is active or not.

    This utility would not work for the administrator would not worry so much, because the administrator is supposed to know what he does. But the limited user doesn't have access, that bother anymore.

    In Administrator, this utility works quite well. But during a session of limited user, if I try to launch it in [runas / user: admin "C:\Program Files\TOSHIBA\Windows Utilities\TACSPROP.exe"],
    I am replied that the file TCMSVR. DLL is not found. If I launch normally, a message tells me that this utility requires that I am logged on as administrator.

    So, what can I do to use this utility normally, i.e. in a limited user Sessiona? *

    Hello

    Well, you should try to activate the rights for the TACSPROP.exe.
    To do this, you must enter the operating system as an administrator.
    Choose the application, right click. There is a Security tab. Here, you need to activate the permissions for all users.

  • Satellite P10: Question about the limits of upgrade of RAM and HARD drive

    What are the limits to upgrade my laptop Satellite P10? Currently, I use 1 GB of RAM (2 x 512) and I still have the original 60 GB 4200 RPM HARD drive. I'm mainly interested in upgrading my hard drive to at least get a 7200 RPM 100 GB disc. Better would be one of the ones 24 hours server as Hitachi HTE721010G9AT00, I have just turned off my computer. Which one to take and are there limits (BIOS) (keeping in mind that there will be 200 and even the 250 GB drives next year)?

    RAM: should I put two 200pin SO-DIMM 333 or 533 or should not change at all as it works very well and stabil now?

    Hello

    In my eyes you should follow the guidance of Toshiba line and must use the memory modules that are recommended in the user guide. But if you can also try to test with 400 Mhz or 533 Mhz. I think that each dealer notebook or memory could do that.

    I think the BIOS might be able to handle the hard drive with capacity of 30 GB / 40 GB / 60 GB / 80 GB, Bus Master IDE with ultra DMA 100 synchronous
    In my opinion the BIOS does not recognize the larger HARD drive.

  • Add 9188 Chassis to the system definition file (sdf)

    I want to measure the basic in Veristand 2011 without a custom device channels.  In the system definition file, how can I add a 9188 chassis? And how do I add a thermocouple on channel 0 on a series c 9213 module?  Thank you!

    Hello

    You work with a Windows or device in real time?

    If you use VeriStand able to work with a Windows-based system, the addition of a cDAQ-9188 should not be a problem; the equipment Discovery Wizard he will come if it's in the same network as the Windows computer. Having problems with this?

    If you have a real-time like a Pharlap ETS PXI controller running target, you will not be able to use the cDAQ-9188 at all because it is not supported in real-time operating systems. If you work with a target in real time and you need the CompactDAQ you either move to Windows or we a USB CompactDAQ instead, like a cDAQ-9178.

    Please refer to this topic. The second post made by a Product Support Engineer and I was able to confirm that the information is still valid even for the latest versions of NOR-DAQmx and VeriStand. You can also check the compatibility in real-time in the Readme of NOR-DAQmx 15.5.

  • LabVIEW:EXE generates the error 1003 calling plugin with the type definition

    Hi all

    I am running LV 2012 on a Win 7 machine. I had this same problem with LV 2011, so I'm sure that's not associated with version/upgrade.

    Go to a LV-built EXE, I try to call a dynamically loaded Subvi. I did it several times with success before, so I think I know how. I prefer to use the call by reference, but I get the error 1003 Open Ref VI (with the type specifier). If I use the type specifier, can I open the Subvi, but the State is listed as 'bad '. Then, I went to recursively through all the subVIs (~ 25 in total) and concluded that the only item with a status of 'Bad' was a type definition.

    I checked several times, several different, that all ways the subVIs (and the definition of Type 'bad') are available to the Subvi dynamics. I did that the type definition is correct. I have also made sure the subVIs are stored as .VI files in the same directory and not within an EXE file. When I try to run the VI run call node, I still get the error 1003. I checked the path that displays in the error dialog box is the exact path for the Subvi (it would be for other VI properties and methods working properly).

    Why can't I run a sub - VI loaded dynamically from an executable if it has a type (a group of 3 trails) as output parameter definition?

    I just tested an idea: rename the library from project to project A create script. Now when it loads, it does not disturb what he must internally with externally called Subvi (dynamic). It worked the first time!

  • Beyond the limits of voltage on USB 6008?

    I use a USB-6008 to measure analog differential in the range of 3 to 5.3 V. I chose this range, because outside this range, I'm not interested in what the tension is, knowing that his "on the rail", but to aid resolution of the ADC in this range.

    So for a signal of ~0.05 supply V, I expected to read 3V, telling me that the voltage is lower than 3V, but again it returns 0.05v?

    As it was unexpected for me, could someone please explain what can / should I expect of my USB6008 of the responsed to the signals that are the limits? Is there an effect of "rollover"? Should you return the value to the limit? Depends on how far the limit is?

    Thanks for your help!

    Entry level do not think that way. You specify the range is that you wait for the signal and the DAQmx driver will set the most appropriate range that the device supports. The actual ranges are indicated in the guide. In your case, because you specify a max of 5.3, the device would be defined the +/-10 volts range.

  • Cannot detect the limits of reverse front/market

    I have problems with the switches front and rear for my stepper motor system. When I created a NI Softmotion axis in Labview, no matter how to set limit switches, either appear as assets or both inactive, regardless of the position of the platform. I use for my end of race, photointerrupters. When I don't have the equipment under voltage, the photointerrupters works as expected and give a signal of 0 V when the platform is not the limit and V 5 beeps when the platform is at the limit. But when I try to use the Labview interactive panel (or in a VI elsewhere too) the limits are not detected and behave differently as well. I got a voltmeter connected to see how the tension behaved and pressure readings are odd. In a case when I tested the 'active' signal of each switch, was one of the limit switches to 6.7 V and the other was at 3.7 V, even if they had the same exact wiring and configuration. I'm completely stumped on how to connect these in the system so that they work or how to configure Labview to properly recognize these limits (meaning sourcing vs shipwreck and active State power). I searched the forums and manuals, but I can't seem to find a solution. Here are more details on the system:

    The engine is now a platform back and stepper motor is powered by a Kollmorgen P70530 stepper drive. To communicate between the command of stepper motors and the computer, I use a cRIO 9076 with a NI 9512 in the chassis. To connect the end of race in the system, I used the NI 9512 connection block 37 pins. Switch in the photo that I use is a strong GP1A05 CIPO Photointerrupter with connector. For this photointerrupter, there 3 pinout: a Vcc input (voltage source), a GND input and output Vout. The SCR is supposed to be connected to a source of 5V and GND to the mass (obviously) with resistance to pull-up between Vcc and Vout (I use a k 10 Ohm resistor as who has what has worked for me in the past with this specific photointerrupter). Vout is supposed to give a signal 5V, then the limit would be active and 0V when it is not active. How I had connected the photointerrupter to the connection block 37 pin was as follows: to the limit before, I had the VCC to pin 9 (+ 5V OUT), GND was on pin 3 (COM) and Vout was on pin 1 (before the deadline). For the inverse limit, I had the VCC to pin 9 (+ 5V OUT) GND was pine 24 (COM) and Vout was on pin 20 (inverse limit). I also tried to connect terminals GND the switch of the photo to the GND (shield) pin on the plate at terminals without success either. In regards to Labview, I am running Labview 2011 SP1 on my computer.

    If you have any ideas, I would greatly appreciate it if you would share that I am really confused with something that seems on the surface to be quite banal.

    Thank you

    Steve:

    I am puzzled too-

    Manaual I looked:

    http://www.NI.com/PDF/manuals/372153d.PDF

    Your PIN seems correct.

    I assume you have a power supply connect to Vsup and COM.

    Research on page 3-10 for sourcing of the shows without pullup resistance, have you tried remove the 10Kohm?

    But watching page A-3 for levels of limits, it shows<5V for="" low="" and="" 11-30v="" for="">

    I'm confused-pg 3-10 looks like the 9512 provides its own pullup still pg A-3 show the necessary voltages for entries.

    I hope someone can clarify this.

  • What element is the limiting factor?

    Greetings.  A previous employee in my company had set up a a universal station machine Instron who communicated with Labview via GPIB to test.  This station has served us for the last 6 years, but now we need to upgrade and I do not know what component to upgrade.  Sorry that my first experience with labview (other than by using the front of the GUI).  In the last days, I read the manual of Labview and it seems fairly intuitive.

    Pretty much all I want to do is read my load and position several times per second.  In reading the other posts and the manual, I was able to move the instrument I/O Assistant in a flat sequence structure and surround by two millisecond timers.  He confirmed that the I/O intrument Wizard is the limiting factor in the block diagram.  Currently, we receive readings on each ms 160-220 (it is surprisingly incompatible).  It is the same value I get timers.  I wish that the time between the readings more as 20ms or even 2 ms.

    Here's my system:

    LabVIEW 7 Express

    Windows NT 4.0

    Pentium 2 400 MHz

    Card OR PCI-GPIB

    Instron 8511 controller

    In order to obtain performance I want what components do you think I will need to replace and that tests can do to learn more?

    Any help is greatly appreciated.

    -Daniel

    The user?  SCNR

    Speed your Instron GPIB just tells you that it would be able to send data fast enough. I do not know this instrument, but I would like to dig into the manual to see if it is possible together in a way he could make use of this speed. Perhaps by internal scripts, triggered material acquisition, low resolution... ask 1000 values once instead of a 1000 times.
