Control pump with daq

Hi, I've recently purchased the PCI-6221 M series DAQ card.
I have a BALDOR pump controller that I want to control. The controller takes 7 digital inputs as control.
What is the best way to implement this using Labview? I want to have buttons on the VI that will allow the user to start,stop,choose direction of the motor (all these are simply controlled by a single digital signal each).
Will I just have to use boolean buttons, and one of the states will be to output a signal?
Thanks!
Sunny

Hello Sunny. Thank you for contacting National Instruments. I am not too familiar with the BALDOR pump controller. Does it start/ stop/ choose direction by setting a specific digital line high or low? If this is the case then you can use an example in LabVIEW that specifies if the line is high or low based on a boolean control. Go to the Help Menu and select Find Examples. Browse Hardware Input and Output>>DAQmx>>Digital Generation>>Write Dig Chan.vi. Please let me know if you have any questions. Have a great day!

Control pump with labview

Hi,
I am new to Labview and still trying to figure out some of the techniques so please bear with me. I have two pumps (EagleDrive Micropumps) that are connected to a DAQ NI 9263 to read their voltage so that we can monitor the flow through the pumps. The tachometer out is a 0 to 5 VDC square wave. We want to be able to send a signal to the pumps to control the output voltage between 0-5 VDC through a Labview program. Is there any way to do this? And if so, what would be the best way to go about this?
Thanks!

After playing around with the program, I believe I am able to control the pumps with the attached VI. We have not hooked up the pumps yet, just have been using a multimeter to be safe. The VI is running well but when it is stopped, the multimeter reads the last voltage that was set by the VI. Does this mean that the pumps will keep running when the VI stops? And if so, how could I set the VI back to zero when it stops?

NI module for control pump

I have a pump which accept 0-10V analog to change RPM. with BNC connector, when Volt is higher than 445mv, pump will start.
I look for a Analog output module from NI. Could you give me some advice? Which module is good to control pump flow rate and on/off?
cheaper one is prefered
Thanks

So it depends on a few things.
What kind of output rates do you need? How do you want to house your module? We have PCI cards that slip into the computer, and USB devices that sit outside the computer. The USB devices typically have slower frequencies.
Here is a search that I did on ni.com for DAQ products with at least one analog output port.
http://sine.ni.com/np/app/main/p/bot/no/ap/daq/lang/en/pg/1/sn/n17:daq,n36:19,n3:7691/
It seems one of your cheapest options might be the USB-6211, whose analog output has a range of +/- 10V.
http://sine.ni.com/nips/cds/view/p/lang/en/nid/203224
And just for future reference, though this is in some sense motion control, since you're intending to use a simple analog output device to communicate with your device, we typically post those questions on the data acquisition boards, since you're more likely to have helpful eyes see the issue. That being said, hopefully the above links help. Let us know if there are any more specific parameters you have for your communication. Thanks!

I have 3dparty software wirelessly with a cryptographic authentication system without my consent (seems to be new technology developed by stanford) obtaining ownership of my iPhone 4s software and controlling it with remote device to jail break. Now what?

I have 3rd party software wirelessly injected and used on my iphone with a cryptographic authentication system without my consent (seems to be new technology developed by stanford and apple security is not updated for this technology) obtaining ownership of my iPhone 4s software and controlling it with remote device to jail breaking my phone, adding and removing software, changing settings all from a remotely controled device from different location (I have a Mac address I'd of this device to know for sure). Almost undetectable. When I look at the legal section of my phone it shows a list of all the unauthorized 3rd party software "as is" copyright encrypted on the phone. This is the most basic way to legally steal software of any kind. Because of this legalality 3rd party ownership have total control of certain software correlated with hardware use including visualization technology, etc. most people luckily will never have this happen to them so it's unlikely many readers have not a clue of what I'm saying currently. Either way, without needing to obtain specific warranty of any kind "as is" copyright control makes system restores not a solution because the source code is not directly encrypted on the actual hardware device only a copy right notice must appear on the specific device 3rd party software validation making it extremely difficult for me to take control of the situation. Apple claims their iOS technology prevents this type copyright obstruction from being possible, however, according to my phone a new form of technology was used developed by Tom wu of Stanford university called the STANFORD SRP AUTHENTICATION TECHNOLOGY which uses Some form of cryptographic authentication system and uses quote "secure remote password" which seems to suceed in hacking iOS apple technology apple claims is not possible to jailbreak an unstolen phone or without the owners consent As well as loading the device with 3rd party copyright Notices to make all of this legalized. My phone shows atleast 30 pages worth of legalized 3rd party copyright permissions! Yesterday my apple care provider labeled me a jailbreaker and refused to look at my legal documented proof which completely blew my mind because it voides my apple care contract I spent 100 on. This employee did not take all factors into consideration and made quick assumptions as well as verbally speaking to me as I'm an automatic criminal. I left the store yesterday with no payed insurance help on a problem I had no control over and couldn't prevent, leaving with voided contracts. This is an apple users worst nightmare and I have spent days researching all of this like i am some kind of lawyer only to be able to use my phone the way it should and spent alot of money on. I can legally backup any claim I have just wrote above currently and have a large source of data collected to prove apple is wrong in voiding insurance support on this issue. The problem lies in apple avoiding and not wanting to believe their software can legally be obtained ot "hacked". Yet still labeled a jailbreaker basically.. What should I do????? Been to local apple store 3 times and rebooted my phone as well sprint service restore 4 times and spoke with reps twiice on the phone. Spoke with my phone provider who said apple has full control over these matters so they can't help me. My case is according to apple "still open"...Anyone else heard of this or of Stanford's office of technology licensing? Maybe I need to buy a blackberry again or just use a landline so I can stop being my own lawyer and focus on other productive areas in life instead of this horrible mess. I shouldn't have to prove to apple I not a jailbreaker they should have to prove I'm one before voiding support I desperately need!!

Yes, I think most of us do understand what open source software is. It sounds as if you don't. Here's some information:
Open-source software (OSS) is computer software that is available in source code form: the source code and certain other rights normally reserved forcopyright holders are provided under an open-source license that permits users to study, change, improve and at times also to distribute the software.
Open source software is very often developed in a public, collaborative manner. Open-source software is the most prominent example of open-sourcedevelopment and often compared to (technically defined) user-generated content or (legally defined) open content movements.
from http://en.wikipedia.org/wiki/Open_source_software
Yes, Tom Wu of Stanford wrote a paper on something called Secure Remote Access Protocol. It's a form of Asymetric Key Exchange and has nothing to do with hacking anything. It's actually intended to protect data.

How to change a setting in the Java Control Panel with command line

Hi,
I am trying to figure out how to change a setting in the Java Control Panel with command line or with a script. I want to enable "Use SSL 2.0 compatible ClientHello format"
I can't seem to find any documentation on how to change settings in the Java Control Panel via the command line
Edited by: 897133 on Nov 14, 2011 7:15 AM

OK figured it out. This is for the next person seeking the same solution.
When you click on the Java Control Panel (found in the Control panel) in any version of Windows, it first looks for a System Wide Java Configuration (found here: C:\Windows\Sun\Java\Deployment). At this point you must be wondering why you don't have this folder (C:\Windows\Sun\Java\Deployment) or why its empty. Well, for an enterprise environment, you have to create it and place something in it - it doesn't exist by default. So you'll need a script (I used Autoit) to create the directory structure and place the the two files into it. The two files are "deployment.properties" and "deployment.config".
Example: When you click on the Java Control Panel it first checks to see if this directory exists (C:\Windows\Sun\Java\Deployment) and then checks if there is a "deployment.config". If there is one it opens it and reads it. If it doesn't exist, Java creates user settings found here C:\Users\USERNAME\AppData\LocalLow\Sun\Java\Deployment on Windows 7.
__deployment.config__
It should look like this inside:
*#deployment.config*
*#Mon Nov 14 13:06:38 AST 2011*
*# The First line below specifies if this config is mandatory which is simple enough*
*# The second line just tells Java where to the properties of your Java Configuration*
*# NOTE: These java settings will be applied to each user file and will overwrite existing ones*
deployment.system.config.mandatory=True
deployment.system.config=file\:C\:/WINDOWS/Sun/Java/Deployment/deployment.properties
If you look in C:\Users\USERNAME\AppData\LocalLow\Sun\Java\Deployment on Windows 7 for example you will find "deployment.properties". You can use this as your default example and add your settings to it.
How?
Easy. If you want to add *"Use SSL 2.0 compatible ClientHello format"*
Add this line:
deployment.security.SSLv2Hello=true
Maybe you want to disable Java update (which is a big problem for enterprises)
Add these lines:
deployment.javaws.autodownload=NEVER
deployment.javaws.autodownload.locked=
Below is a basic AutoIt script you could use (It compiles the files into the executable. When you compile the script the two Java files must be in the directory you specify in the FileInstall line, which can be anything you choose. It will also create your directory structure):
#NoTrayIcon
#RequireAdmin
#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
#AutoIt3Wrapper_UseX64=n
#EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****
Func _JavaConfig()
     $ConfigFile_1 = @TempDir & "\deployment.properties"
     $ConfigFile_2 = @TempDir & "\deployment.config"
     FileInstall ("D:\My Documents\Autoit\Java config\deployment.properties", $ConfigFile_1)
FileInstall ("D:\My Documents\Autoit\Java config\deployment.config", $ConfigFile_2)
     FileCopy($ConfigFile_1, @WindowsDir & "\Sun\Java\Deployment\", 9)
     FileCopy($ConfigFile_2, @WindowsDir & "\Sun\Java\Deployment\", 9)
     Sleep(10000)
     FileDelete(@TempDir & "\deployment.properties")
     FileDelete(@TempDir & "\deployment.config")
EndFunc
_JavaConfig()
Now if you have SCUP and have setup Self Cert for your organization, you just need to create a SCUP update for JRE.

Issue in treeview control along with page viewer web part showing the sub sites from MMS

hi,
Am having a treeview control populates with values from MMS - Managed Metadata Service.
[ Products ]
----->ms office
           ----->word
            ----->excel
             ---->powerpoint
-------->Collaboration
                ---->   sharepoint 2003
                 ----> moss 2007
                 ----> sp 2010
                 -----> lync
all these values excel, word, powerpoint are sub sites created under ms-office site collection.
and sharepoint 2003, mos 2007, sp 2010, sp 2013 are sub sites created under collaboration.
now, on the page load, end user clicks on word and he should navigate to the sub site "wordsite" and it should show the home page of word sub site.
we have created a page viewer web part and assigned the url property of the page viewer to the sub site url.
but the issue is, when end user clicked  on the child node "powerpoint", the page did a Post Back and treeview control immediately collpased and it shows the Products [top level - parent node] only.
Am unable to set the current selected value- ie here its excel and show the excel node in the trewview.
how can i get this child tree node as the selected node.
help is highly appreciated!

Check if below can help

Anyone been able to get the sap.ca.ui.FileUpload control working with a Gateway OData service?

Hi,
I have been trying to get the sap.ca.ui.FileUpload control working with an OData Gateway service, specifically /IWPGW/TASKPROCESSING which is the service used by both Fiori Approve Requests and the Unified Inbox.
I have looked at the sample application in the Explored at SAPUI5 Explored
I have managed to replicate that and get it to work, but as soon as I switch it from a JSONModel to an ODataModel I get javascript errors from within the setModel method of the control. I have redefined that method and corrected the errors, which enables me to get a bit further, but then I hit more errors, and other strange behaviour.
Either I am doing something completely wrong, or to me it appears as if this control is still extremely buggy and maybe either not designed to work with an ODataModel, or just hasn't been tested using an ODataModel. I'm hoping it is my mistake.
So has anybody out there successfully managed to use this control connecting it to a Gateway OData service? If so please share your experience.
Thanks,
Brad

Hi Pauline,
Same issue I had, I switched to using a sap.m.list and handling the press as follows:
attachmentsList.bindItems(workItemPath + "/Attachments", new sap.m.StandardListItem({
                           type: sap.m.ListType.Active,
                           title: "{FileName}",
                           description: "{CreatedByName}",
                           icon: "sap-icon://doc-attachment",
//                         counter: "{FileSize}",
                      info: {path : "CreatedAt", formatter: dateTimeFormatter},
                      tap: function(oEvent){
                            var oContext = oEvent.getSource().getBindingContext();
                            var media_src = oContext.getProperty().__metadata.media_src;
                            sap.m.URLHelper.redirect(media_src, true);
                    }), new sap.ui.model.Sorter("CreatedAt", true));
So sap.m.URLHelper.redirect(media_src, true); is what loads the attachment.
See the full function handler:
function(oEvent){
function(oEvent){
              var oContext = oEvent.getSource().getBindingContext();
              var media_src = oContext.getProperty().__metadata.media_src;
        sap.m.URLHelper.redirect(media_src, true);
This should be enough if you only want to list and display the attachments, then you don't really need the FileUploader control as that is more advanced and handles upload, display, change and deletion of files.
I only needed to upload and display files, so I used a list to display it and created a separate upload button using the sap.ui.unified.FileUploader control.
Hope that helps.
Cheers,
Brad

Is there a way that I can control iTunes with the iPhone without any internet connections?

First let me say that I am ready to throw this POS in the lake. Is there a way that I can control iTunes with my iPhone without any internet connections? On my houseboat I have a wifi router and want to connect my phone to my computer to control my music which plays from my computer through my stereo. I can easily do it with my laptop without having to jump through any internet APPLE BS , but I dont want to have my laptop out on the deck. I just want to use the phone as a remote control.
Remote wont do it because it keeps saying Im not connected to the internet, even though is is connected to my computer. Same problem with JumiAmp.

It should have an option to manage iTunes library without network connection, like Bluetooth or connect directly to the computer without a router or wi-fi, i live outsite of the city and i dont have the ability to control my iTunes librry from the iphone

Hello, I want to use version controlling software with Labwindows.

Hello All.
I want to use version controlling tool with Labwindows/CVI. Actually version controlling tools work for text files and by using the tool i can do version controlling of my .c and .h files in Labwindows/CVI project. But is there a way to do version controlling of .uir files also. Version control tool can detect the changes made in .uir file but is there any tool that can be used to compare and merge .uir files too just like text files operation for version controlling.
Regards

Hello Moshi,
Personally I never understood how the integrated version control system of
CVI works, but SVN (and TortoiseSVN) works fine with CVI projects.
UIR files are treated as binary, as they should be, and that's about all.
You could put the .tui file under version control instead, but I don't think
it's worth the bother.

After you send "PT19" to the 8757, usually at address 16.
Send the commands you want to go to the 8350 to address 17.
To terminate the passthru mode, send any command to address of the 16.
Ex:
To Address 16: PT19;
To Address 17: FA 8 GZ;FB 16 GZ;PL 0 DM;
To Address 16: C1 IA;

Multiple controlling area with same chart account

Hi Experts,
can we consolidate multiple controlling area with same chart account in SAP BI?
for example, if in R3 I have 4 Controlling Areas with the same chart of accounts, I can get an standard BW reports summarizing them.

Hi
Chart of accounts i.e. 0CHRT_ACCTS is an attribute of Controlling area. This means each Controlling area will have it's own chart of accounts. This chart of accounts could be similar in terms of content values. So it is possible to consolidate and produce a report which provides a summary of the chart of accounts.
Cheers

How to control animation with touch

Hello! I need some help with controlling animations with touch. I am building a fake app and need to 'unlock' an iphone (slide an arrow along a track and then have it fade into another page). I have been using http://forums.adobe.com/message/4865693 that thread. The prototype link listed there is similar to waht I need to recreate, but I think I need an 'on touch' actino instead of a mousemove one.
http://assets.ordienetworks.com.s3.amazonaws.com/the_occasional/checkerPro/checkerPro.html
That is a link to the Edge file I have been working on, using the info in the thread above. It is broken at the moment, and I am terrible with javascript and have no idea how to move forward. I have figured that I'll need an 'on touch' action instead of the mouseover one, but I'm not sure how to build it.
If there is a working example of this on a different thread that I've missed I'd love a link as well!!
Thank you!!

Hi, akall-
There are a number of touch events that you can use to accomplish what you want. You can try using the touchmove event instead of the mousemove event, and stick your code in there.
Hope that helps,
