• problem with a block of memory in labview 2009

  Hi all

  I have "ERROR: MapLib:979 - LUT4 symbol" during the compilation process (lots of errors like this), and I discovered that the reason of my problem is block of MEMORY.

  To be sure that the problem is in this block, I did a very simple project in LabView 2009 (on FPGA Target PCI5640R) only with the use of this block you can see in the photo, as well as in file test_memory block.lvproj attached link: https://www.dropbox.com/sh/u87f1oihelmm4dq/Jo_6-bICSf

  

  I have a problem with compiling VI with this block, and I have so many errors like:

  ERROR: MapLib:979 - LUT4 symbol
  "window/Thatcher/n_00000036/nSCTL_00000013_00000014/n_000000A3/cOutLoc<0>1.
  (output = window/Thatcher/res000001ed_wi<2>) is the input signal
  "window/Thatcher/res0000020d_wo<1>" that will be deleted. See Section 5 of the
  Map a report file to find out why the input signal will become conveyors.

  or

  ERROR: MapLib:978 - LUT4 symbol
  "window/Thatcher/n_00000036/nSCTL_00000013_00000014/n_000000A3/cOutLoc<23>1.
  (output = window/Thatcher/res000001ed_wi<25>) is an equation that uses
  input pin I2, which no longer has a connected signal. Make sure that all the
  the pins used in the equation for this LUT are signals that are not cut
  (see Section 5 of the report file map for details on which signals were
  adjusted).

  Entire report, you can see in the file report.txt on the attached link.

  I would appreciate if someone could take a look at my problem with simple project and suggest me a solution.

  Hi all

  I find a sollution to my problem.

  In memory-properties-general-setting up, I changed the block to look up Table memory, and I compile memory.vi and run it successfully.

  I did change as you can see on the picture:

  

  Just, can you tell me is it all "bad properties" and limits the use of this type of memory (Look up Table) of the implementation?

• Any camera regardless of the interface is available for use with the LabView interface.

  Hello

  I intend to go for some CMOS camera,

  but I have a huge doubt before buying, the camera of menttioned above is not anywhere in this list. Nor can I see any type being supported USB device.

  The question is

  1. is a camera regardless of the interface is available for use with the LabView interface?
  2. Can I build a VI to communicate with any device image and recording of camera and take the data?

  Any kind of help or advice is greatly appreciated... I have to buy a CMOS camera and begin to run.

  Thank you...

  Hello Virginia,.

  I am pleased that this information has been useful, one thing I wanted to mention is that USB 3.0 has its own standard USB 3.0 Vision which is currently not supported. If this camera is also Direct Show compatible then you will be able to acquire an image using IMAQdx and manipulate all the attributes that are published to the API Live Show.

  I hope that USB 3.0 Vision will be supported in the near future, and we tentatively announced for this standard of communication for the August 2013 Vision Acquisition Softwareupdate.

  See you soon,.

• A module C - DAQ exists which will interface with standard RV - C?

  Module C - DAQ exists that if interface with standard RV - C (vehicles recreational CAN)? RV - C seems to be a variant of J1939 according to Wikipedia.

  I would use 9861 OR or NI 9862. I'm new on CAN protocol and evaluate some assistance.

  I've never used RV - can, but according to Wikipedia, the rate is 250Kbaud, so you'll want high speed CAN peripheral, 9862, you can set baud rate on init of the material.  After installing XNet and cDAQ software, you have a max bus monitor and several examples in the example Finder to read and write raw images.  After that, you'll want to read on the standard to understand how to format and analyze the data.

  Also if you have any questions, you can post on the Sub-forum Auto , they can probably answer more specific questions.

• 4235 with multiple monitoring Interfaces?

  This is a general question as to whether anyone is running on 4.0 4235 sensor code with multiple monitoring interfaces?

  Basically, I wonder if you have any comments on the performance or if you run into any problems with the configuration. I have not seen too much documentation for configuration in fact this, so I wonder if there are additional requirements or considerations.

  Hi Chad,

  With ID 4.0, you can only montior using an interface to sniff. 4.1 you will have taken care of multiple monitoring interfaces.

  As far as performance goes, I don't see any problems and more to ensure that the management station is able to handle the upcoming alarms when using several interfaces.

  Thank you

  Try using the command "backup interface" on the secondary ISP interface.

  http://www.Cisco.com/en/us/docs/security/ASA/asa72/command/reference/b_72.html#wp1338585

  You need to increase the level of security to 1 for this interface.

  By default, EasyVPN uses the highest level of safety inside and the lowest outside.  Anything between the two must be set manually.  I assume you have an interior vlan defined but not added to the posted config.

• Using NI 9870 with drivers of the robotic Module

  Hi all

  I am using quite a few sensors that are supported by the LabVIEW Robotics module (GPS, MIO, compass and probably a LIDAR soon.) However, I would really like to be able to use the module series OR 9870 RS - 232 in a CompactRIO to interface with these devices (currently they are connected directly to a PC.) Unfortunately, I do not know if there is a way to do it without having to rewrite the drivers for the FPGA. Someone has encountered this before or maybe knows a way I can do this without reinventing the wheel? Thank you!

  Brandon

  BrandonGT,

  Worked on a similar problem.  Take a look at this example .  Note how the service contact numbers is used to add an identifier to the data before it is put into a common FIFO.

• How do I program labview to read all 8 compact fieldpoint modules?

  I am new to fieldpoint and I my set-up block diagram to read 8 strain gauges using a SG-140 module.  My basket is filled with strain gauge modules 8 SG-140, and I need to know how to fix my diagram to read all 8 modules of SG - 140.  So, I need a total of 64 strain gauge readings 8 modules of SG - 140.  Can I do this without really copying what I've already done 8 times more?  Is it possible to use a loop or something to read the 7 other modules?  I appreciate any help I can get.

  My opinion about not having to duplicate the table of index based on what your VI was showing at the time.  Once you have the VI implemented with multiple modules, then you will need to implement an array of unique Index stretched far enough to get all the channels of interest.  From a 2D array, you need to connect both the row index and column index for a single scalar element.  So first channel would be 0 and 1, then 0 and 4, canal next 0 and 7.  The next module would be 1 and 1, 1 and 4, 1 and 7.

• Generator interface user Web supports the DSC Module?

  A simple question:

  Can I use the generator of the user Web interface for Web client access to a Windows-LabVIEW System with the DSC module or supportet has this tool user interface only the LabVIEW base for the objects in the front?

  For example: Can I use a web client to review historical data and alarms? Can I use a web client with full support for "The front panel security dialog box" (see http://zone.ni.com/reference/en-XX/help/371618F-01/lvdsc/front_panel_security_db/)?

  Best regards

  Frank

  Hi Frank,.

  Yes, you can use the generator of the user Web interface to access historical data and view the current alarms. The LabVIEW 2010 version of the ASN has several built-in RESTful web services that make the Citadel and alarm available via HTTP data. Here are some resources to provide details on how it works.

  Interact with Web Module DSC Services

  Here is an example that illustrates how to implement web service at the Citadel communication:

• Problem calling LabVIEW DLL with c#

  Dear all,

  I compiled a few DLLs in LabVIEW and called these DLLs using c#.
  I'm having trouble passing in strings and arrays as input and output of the DLL.

  Whenever I try to view the string I have entered in a dialog box (this part is written in LabVIEW DLL), a LabVIEW message dialog box appears and the program just stuck there.

  Whenever I try to enter a string or an array to the dll, Microsoft Visual Studio would display "attempt read or write protected memory. It is often an indication that other memory has been corrupted. »

  I attached the vi and also the c# .sln file.

  Can you guys please advise where am I wrong?

  Thank you very much.

  You must allocate strings and arrays of output!

  private void button1_Click (object sender, EventArgs e)
  {
  output string;
  int [] value;
  StringOutput ("A", "B", exit, 3, value, 4);
  }
  }

  Your variable output and value must be preallocated to ensure storage of 3 items respectively. 4. and since you want to receive the C string that you need to increase this to 4 characters terminated by a NULL value.

  String in c# is also a not a C string of object pointer. You must declare the StringOutput() function as follows:

  [DllImport("SharedLib.dll",CallingConvention=CallingConvention.StdCall, Charset=CharSet.Ansi]internal static extern int StringOutput(StringBuilder A, StringBuilder B, out StringBuilder StringOutput, int sizeString, out int[] output, int sizeArray);
  

  Then call like this:

  StringBuilder output = new StringBuilder(4);int[4] array = new int[4];
  
  StringOutput("A", "B", output, output.Capacity, value, value.Length);
  

  Please note that I'm not a pro in c# and usually do not do much in it. Also that this code has not been tested or updated at all, so probably contains some errors. He however point you in the direction of where to look further.

  What you need to understand, is that the C DLL that you created in LabVIEW has a so-called unmanaged interface. This means c# is not able to know how to manage the memory for the parameters at all and you have to do everything yourself, where the obligation to explicitedly initialize variables output and table with a block of memory préallouée.

• I use pci-6221, I need her to interface with thermocouple with voltage up to 5v

  I use as my pci-6221 or data acquisition card and card 8.2.this labview version gives the constant 10.5 volt signal in at the entrance to analog channel AO on pin 68 and 34. why it shows 10.5 although I did not connect any input.i use type k thermocouple and after signal conditioning with tl0804 I need it interface with AI 0.i channel unaware aware of off the road on the output pins this Card.i need to operate an electric rod that needs 24 volt DC.i give entry to the pins HAVE with variable dc power block after reaching the limit I set(eg:2v) it jumps instantly to 10.5 volts.

  You have your task to acquisition of data configured for the mode differential or asymmetric acquisition for the analog input?

  I don't understand your comment about to connect the pins WITH a DC power supply.  Why is that you connect a DC power supply to the analog input?

  Using an analog output or digital output to operate the electric rod?  I'll assume that you are looking for on/off control.  A digital output is not the voltage or current to drive something that big.  You may be able to find a relay for coil 5VDC.  Check current requirements.  With which you can have the relay to connect or disconnect a power supply of 24 VDC is the actuator.  Make sure you have a protection diode across the relay coil wired, so that the magnetic field of the coil does not damage the analog output of your card.

  Another possibility is to have the 5 VDC output transistor circuit switches the 24 VDC circuit.
