• Control the Arduino with LabWindows

  To the right:

  I've seen a lot of way of communicating with the microcontroller Arduino using Labview. But I'm having a lot of trouble to find ways and examples with LabWindows CVI, can someone help me with the file #include that I need to use in order to communicate with the microcontroller?

  Concerning

  Francisco

  Hi Francisco,.

  Arduino connects to a virtual COM port. The library of RS-232 of LabWindows is able to communicate with the Arduino.

  See using the instrument for the RS-232 (serial) library.

  There are also fine examples on the use of this library. They are installed with the CVI environment.

  See if you can find and post if you need help.

• Serial communication cause the crash of LabView

  Hello

  I'm set to do a serial with Labview. The problem is that the program always crash (no popup error but only LabView don't freeze) when I read or write with VISA.

  I work with a module converter (ADAM 4571) that convert Ethernet to RS-232/422/485. The module is mapped to the computer and the similar work as a COM port. I tested the connection with the Terminal windows and its work. This means that it is not a hardware problem.

  I did the same communication a few weeks with the same material and did not have a problem. I don't understand why it does not work now.

  I give my code as an attachment, but it is not something special except for the block that buffered (which is required for my module), but if I remove it the problem persists.

  Does anyone have an idea what can be the problem?

  Thank you

  Jérôme

  OK, I solved the problem.

  The version of the driver for the converter module mapping was not exactly right, now I change it and its work.

• Connect the monitor to the laptop with displayport/DVI

  Help, I have a laptop Dell 1749 Studio. The machine is less than a year. There an i5-520 with 8 GB and Intel HD graphics. I connect to a monitor ACER X233H. I used the VGA connector on the laptop but wanted a more secure connection. I bought a Displayport DVI cable, but the monitor says "No Signal" I googled around but not found help with Win7 system.

  The photos are interesting. According to the photos, the cable connector is a DL-DVI-D, and the monitor is a DVI - D. I wonder if that causes problems?

  I have an old Samsung 203 b monitor. The monitor has the same connector DVI - D, like the ACER. I downloaded the driver on the Samsung site, on the laptop. When everything is connected, the laptop does not detect the Samsung. The message reads 'another display not detected. This is an another can of worms that I won't do side followed with.

  Time to try another cable, I think, with a regular DVI - D connector.

• I have a dual monitor in the display with a different total 3 registered. How can I get rid of one of the duplicates.

  I accidentally added the same monitor in the display area where you can change the appearance.  I think this causes a problem when I click for a drop-down list, as the drop-down list will be grayed out until I put the mouse pointer in the drop-down list box list, so I'm able to use the right items listed lower down.  However, after I have click on the option I want to use, copy, paste, cut, etc, that particular item will remain on the screen until I have change the resolution and then go back to the original resolution.  I'm afraid to remove the monitor that I would delete that I'm not with my main monitor.

  Thank you for your time,
  Frank

  Hi Frank,.

  I suggest you to change the main view and check if that does the trick. To do this, follow these steps:

  a. click Start and select Control Panel.

  b. click view , and then select change display settings

  c. click the type of view you want as primary (or display 1) and select the option 'Allow this my main screen'

• 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,

• How to see the chart with labview WebService

  Hi all

  I am looking in the labview 8.6 web services option. I've seen some simple examples that can be found here on the website of the NC. But these examples generally deal with static data. As in the example of the sum, you enter your parameters in the URL, and the result is displayed in your web browser.

  What I want to do now is display a chart in my web browser that show a mobile signal. But I'm having a hard time the realization of this. How to make this work? Do I need AJAX, Measurement studio? or is it sufficient to use the labview web service.

  Best regards.

  ynse,

  You are right that web services do not require runtime must be installed on the client. Unlike the remote panels that make the VI on the client, web services nothing do with the client at all. Simply, the web service is running on the server and returns data to the client. The customer can return the data, but he wishes.

  Your question about studio of measure and AJAX is really asking questions on the client end. You can certainly use the AJAX controls that are updated with the data they acquire a web service from LV. A graph, however, is extremely difficult because javascript has not yet drawing capabilities.

  Web graphics I've seen do one of the following:

  -'Draw' the points on graph using HTML elements with javascript. It of complicated, would be difficult to get working on all browsers and would have problems of severe performance with large data sets.

  -The web service returns an image of a graph that refreshes the client. It takes more bandwidth than necessary, and the server must be able to take a snapshot of the graph. (LV real-time cannot use this approach.)

  -The graph is rendered using a plugin for the browser. There are many technologies that can be used to do this: Java, Flash, Silverlight, etc. The example you mentioned used flex from Adobe which is a valid approach that you should not be quick to dismiss.

  Measurement Studio is not my area of expertise, and I don't know what it can provide for the creation of a graph. What it provides probably made use of one of the above methods.

• Satellite A660-17 t - PC Health Monitor shows the problem with the battery

  I have an A660-17 t I've had since November 2010, I used a good amount, but not always on the battery, I believe that the battery has between 10 and 20 on this charge/discharge cycles.

  I have updated the BIOS to v1.80 when I got the laptop, everything seemed to go well. Recently, in the last 2-3 weeks health monitoring software reports that the battery is in poor health, showing that the capacity is reduced to 40% of the original capacity. I do not believe this like when I work on battery I get several hours of use.

  I have today updated BIOS v1.90, although there is no changelog that I can find, he says just "enhanced features" or similar.

  Is this really a faulty battery, or it is somehow that the software correctly reads the value of the capacity of the battery due to a change in Windows or another change in the system? I don't see how a battery can work for the same amount of time it has always done and actually have a fault.

  Any thoughts? Should I return it to the retailer and report an outage, or is it worth the wait to see if a future update of operating system or driver solves this problem?

  Thoughts welcome!

  Hey,.

  > I do not think this as when I work on battery I get several hours of use.
  This means that you have the same time remaining on battery as before you saw the error of the integrity PC monitor?

  In this case, it seems that the battery is ok and it's maybe s simply the wrong tool of Toshiba information. Then I recommend to reinstall PC Health Monitor, which you can download from the official website of Toshiba:

• Read the serial number of the device in LabView COM port

  Hello

  Is it possible to read a device COM port number in LabView? I would like to make an initialization of the program following the right port COM of a device, for example a USB temperature reading device, and set the COM port as the correct port at the start of the main program of LabView. I want to do that, because a USB device gets usually different dedication of COM port on different computers. Our application runs on 80 different computers. A program like that would be very nice.

  Can someone help me?

  Paal

  Another thought. It also has a place where certain standards can save you a lot of time.

  You have 3 dongles by machine. When setting up a computer are these three dongles * always * assigned to, for example, com 3, com 4 and com 5.

  Similarly, always check that instrument 1 is always on com 3, tool 2 is always on com 4 and 3 device is always on com 5.

  This convention will also simplify debugging...

• LabVIEW Interface for installation of the Arduino

  I want to install the LabVIEW Interface for Arduino Toolkit, so I can control an Arduino Uno R3.  Say the instructions to download and install the VIPM and then you can download and install the Toolkit through the VIPM.  The only problem is that workplace of our company doesn't have access to the internet for security reasons, so the VIPM will not be able to download the Toolkit.  How can I download manually the Toolbox for a laptop without LabVIEW, save it on a usb key, then install manually on the workstation with LabVIEW?  Any help would be greatly appreciated.

  I asked the very question sometime back and here is the answer I received. I decided to use another computer on the network for the work of the Arduino, so I never tried what was suggested.

  Let us know how it turns out.

• RS-232 via TCP/IP with LabView

  Hello

  I have currently a standard equipment is read through a RS232 converter TCP/IP hardware.

  On the computer with labview, I use a third-party serial port virtual that data reads the TCP/IP and converts this COM port data pack

  I then read the port COM normally with VISA.

  I would like to remove the third-party TCP/IP software RS232 and LabView read the TCP/IP port and convert to series.

  How could do?

  More details about the hardware and the 3rd party software;

  thydzik.com/Monitor-cms2000-Inverter-via-tcpip-usr-tcp232-E4-rs232ip-Convertor/

  More information on labview here code;

  thydzik.com/log-Solar-generated-to-pvoutput-with-LabVIEW/

  I don't think it's as complicated as you seem to expect. Try the VISA TCP approach. Create a resource of VISA TCP, in raw mode, as explained in the white paper. Take your existing code, replace the COM resource with the new TCP one, remove the configuration of the port series, and it might work. Make sure to close the resource when you stop the program.

  If you want to go with the TCP functions, look at the examples. You open a connection, read and write strings in it, exactly as you would with a serial port and close it when you are finished.

• ACS550 control with LabVIEW

  Hello

  I recently implemented an ABB ACS550 player to control an air blower speed.  I was control the player through the interface on the disc itself.  However, I am now looking to control the device with LabVIEW.  I don't know where to start and I was wondering if someone could explain what I would need the equipment and the basic principles on how this control can be implemented.

  Thank you!
