How to test if the thermocouple is attached.
Hello, I use the cRIO-9023 and the module NI9213 to read the temperature of the thermocouple. I give to the user up to 16 thermometers already programmed in labview to display the temperature. The question I have, is I want to disable the thermomiters if no thermocouple is connected. I called NOR and they said there is no function integrated to test it, so I have to check by comparing the value. for example, if the units are set to fahrenheit, so if a thermocouple is not plugged it reads to the as 2500 degrees, so what I want to do is to check if the type is fahrenheit and if this is the case, then my temperature max value 2000 degrees. Then I can test IF temp? 2000, disable thermomiter.
How can I editor a programming like this statement:
If Type = Fahrenheit THEN maxTemp = 2000
ELSE IF Type = Celsius THEN maxTemp = 1500
Basically I want a boolian to trigger an action to establish an indicator.
Also, if I put an indicator of value of the dome, how can I read it by another controll?
I would like a way to do it without globial/local variables as my cRIO dislikes the.
Thank you!
Use an appropriate comparison function. Most important in this case.

How to test if the pc is connected to the TCP/IP protocol?
Hello
I have a VI how should the data received from another PC, using a TCP/IP connection.
My VI could connect, receive data, but if I lose the connection im not able to reconnect, because I do not know how to test if my pc is connected to the other.
Thank you for your help,
Best regards

Hey,.
I was checking for error 66, I think that it check if the connection has been closed in order to reconnect
do you not think that the error 56 or 60 are better?
with respect,
56 is the time-out. This will depend on your remote service if this should be considered as error or ignored. If it is a server application, it should certainly be able to respond within the time limit. But if your host application is the server and the remote application is the client it is very common to receive a time-out error when querying the client if it has new data to send.
Order the examples mentioned previously, they really give you a good idea on how TCP/IP network communication must all work, even if there is still a lot to improve to create a truly reliable connection. But start from there come back if you get into trouble.

When I want to attach a file to an e-mail message, it is usually the last file I worked on. Firefox to view items in a list in chronological order, with the most recent element at the top. Now, it displays icons (which I hate!) in alpha order, which is therefore not useful. I think that this change occurred after the last update, I have loaded for Firefox. I'd like suggestions on how to get back to my original format. Thank you!
He finally found. But control is certainly in a dark place and the function 'Help' in Word has been totally useless.

Great looks that you know exactly what you want to do, which seems to be the problem? You will find the functions you need in the digital, boolean and comparison scheme.

Just a question... you want to remove some

or do you simply want to reduce the file size of the

How to check if the lid switch is broken on Lenovo Thinkpad X230i?
I have problems with my new Lenovo Thinkpad X230i lid switch and I would ask you how to test if the lid switch is physically broken. Since I bought the laptop a few weeks ago the laptop suspended when I closed the laptop, but still I had to press gently with my finger on the lid so that the laptop has recognized that the cover is actually closed. Now, this trick no longer works.
Now, I would like to find a way to better test if the lid switch is physically not works. I found this article in the forum: http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/X220-does-not-detect-lid-open-close/td-p/49626... and I followed the steps. I entered the BIOS and closed the cover, but on my laptop, the screen goes out, even if the cover is completely closed and even after pressing gently with your finger.
I cannot conclude now that the switch of cover material is actually broken and I need the service of Lenovo?
switch cover on the X 220 and X 230 is triggered by a magnet. The laptop enter the BIOS menu, then use a magnet and see if that turns off the display. IF this is your lid switch is working properly and the problem you are experiencing is most likely software. If it isn't then it is broken, and you need to replace.

How to test my application of ADF mobile browser on Android emulator?
Hello
I created a Mobile browser app. Could someone tell me please how to test on the Android emulator?
I read the information on downloading and configuring (Blackberry) simulators and emulators (Microsoft Windows) to browser Mobile ADF in 'Running Mobile Device simulators with JDeveloper and ADF Mobile'. However they mention no details on downloading and configuring "* Android emulators." Could someone help me please in the present.
Concerning
RajaIf you want to test the browser applications Mobile ADF (those built with components of the Trinity) - then you run your application in the JDev, copy the URL and open in the browser, which is part of the Android emulator.
If you want to test ADF Mobile apps - you deploy to the emulator, and then start the application like this:

How to test the following?
I want to test the functionality by using the method public void moduleDeletionsPending (String [] moduleNames). I had written logic that removes files from an SD card and it works when I call a menu inside my application item.
However, it should only be run when I uninstall the application.
In 9700 Simulator, if I select Options > Applications > [highlight the application] > [open the menu by pressing the Insert key on my keyboard] - I don't see the option to remove the application.
I don't see the delete option for other applications, such as the Klondike card game.
Should I set a property or the permissions of my app should be deleted in a simulator, so I can test the moduleDeletionsPending method?
Thank you.
You will need to 'install' the app in the BlackBerry smartphone Simulator so that your application appear in the list of applications. You won't see here when you perform an execution/debug as, when you use the file, the option of loading or copy it into the directory of Simulator.
The following link explains the different ways to install an application.
How to deploy and distribute Applications
Note that you can install using a simulated so USB connection. Click on the menu of the smartphone Simulator simulation BlackBerry and check USB cable connected. Note that you can not the debugger attached when installing via a simulated USB connection.

How to identify the ASM DiskGroup attached to which disks?
Hi guys,.
In RAC 11 GR 2, how to identify which ASM Diskgroup is attached to which disks... (OS is RHEL 5.4).
We could list ASM starts by,
*#oracleasm listdisks * but this command does not display the disks assigned to ASM DiskGroup.
Even for check location of OCR and voting disks only show Diskgroup name and not the actual discs.
$ocrcheck
$crsctl query css votedisk
(as in gr 10, 2 RAC, we entered /etc/rules.d/udev/60-raw-rules raw file mapping of the OCR, voting disk and other ASM Diskgroup)
Please help me, as long as the customer place, I could see LUN as assigned to the server and get is not an exact idea whose records have been used for OCR and voting disk DATA Diskgroup.
Thank you
ManishAnd for this, you can use oracleasm querydisk. Using that you can identify which device marked for asm or not. for example you can see below the example.

How can I filter the noises of thermocouple using a TC-2095 and SCXI - 1102c?
Hi all
I currently have four TC - 2095 s connected to the SCXI - 1102c inside an SCXI-1001 chassis cards. These thermocouples are floating and I get a good amount of noise (400 Hz 3 phases and same 60 Hz noise) when we turn on some equipment such as fans, and fans. Using this current set up, how can I filter the noise? Or I would need to put in place a new hardware configuration (e.g., the SCXI-1102 cards)?
Hi RALoo,
The 1102 C has a lowpass filter with a cutoff at 10 kHz frequency, so you will not be able to filter into the material with your current configuration.
Your first option is to use a software filter. LabVIEW has several functions that do this. More information can be found here: http://zone.ni.com/reference/en-XX/help/371361J-01/lvanls/filter_vis/
The second option would be to change to SCXI 1102 cards as you suggest. The low-pass filter of the 1102 was a cut-off adjustable to 2 Hz frequency, which will stop the noise of 400 and 60 Hz don't affect your readings.
