Looking fo a Labview DAQ example

I want to measaure with DAQ board. Chart data in real time on a scalable chart. Adjust sampling frequency. save data to spread sheet file. Acces data for time series analysis.

Have you looked at the examples that ship with LabVIEW? There is no single example that does everything you want but there are a lot of indivdual ones that you can combine to get what you want. You can also go here for a lot of additional LabVIEW examples.

Ask for help with LabView Daq and Tek VX4244 VX4101

I use NI VIO-MXI-64XE-10, Tek VX4101 and Tek VX4244 to acquire data in one
Tek 1410A VXI mainframe connected a PII 350/64M computer with MXI2
cable.these modules are used for three independent applications,the datum
are acquired and through preliminary computation, then sent to three TCP/IP
ports the computer served in real time. the burden of the system will be
very heavy because the 64XE-10 need to use up the 100K sample rate
continuously dealed by 50 channels,and the VX4244 need about 30Hz for all 16
channels.
64XE-10 is easily detected by NI software, and I can use LabView Daq
intermediate analog input VIs to acquire data in background, read 50 samples
and compute the mean for each channel,then packa
ge the 50 mean and send to
client end with 40 times a second. I found the speed is satisfactory.
As for VX4244 and VX4101,I can't use LabView Daq VIs,and the driving
functions for LabView with the product are difficult to understand, I want
to know how I can get data and send out efficiently,how to get data in
background,and how to use FDC ?
And for 64XE-10, although the speed is satisfactory, but it use much more
CPU resource, I want to use advanced analog input VIs to build the code,I
want to know where I can find examples using the advanced analog input VIs ?
Best Regards

Hi Gary,
My suggestion is to first work from the Vision RIO examples in the example finder. All of the examples are commented and should at least help you get started. Also, check out this tutorial on Digital Camera Basics, you will notice many of the concepts talked about here in the code itself.

You are correct in your assumption that the image comes in pixel by pixel and you can read more about the image's construction in the article and see that construction in the example codes.

LabView DAQ running more stable under Linux?

Hello,
We are doing LabView DAQ using a cDAQ9714 module (with AI card 9203 and AO card 9265) at a customer site. We are running an excutable on a Windows PC and had a couples of times (3 so far) that the PC just gone freeze for some reason and we lost all inputs and outputs. Each time it happend after the program continous run a few days. So far we have no clue why this is happening (Any idea?)
We need the program to run continously for months and years and absolutely hate the fact that it freeze. Since we couldn't find any bug in the program till now, we're thinking to blame Windows. Then alternative for us is to use Linux os. My questions are:
1. Does LabView run stable on Linux than on Windows? Any data or experience anyone has?
2. To get the same program runs on Linux, I heard I have to buy a LabView Linux delelopment tool and create the excutable from there. Does this involve any extra effort than the Windows one?
3. Does NI have any industrial PC that has Linux OS preinstalled instead of Windows? We bought one PPC 2115 before.
Thanks!
Rgds,
Harry

Harry - the main link here: http://zone.ni.com/devzone/cda/tut/p/id/6909 will show DAQmx (some Linux) and DAQmx Base (Linux/Mac) support for all of our products. It's the same table on the last link it just links a list for all of our hardware offerings. Currently there aren't any offerings with your desired I/O, we have a few multifunction DAQ devices like the USB-6218 that can be programmed with DAQmx Base in Linux. If you are looking to run stand-alone and highly stable applications you may want to look into programming an application with the LabVIEW Real-Time Module and deploy it to a RTOS (Real Time Operating System) controller. You would program the application in Windows with LabVIEW and this additional module, and then distribute the program to a controller. If you deployed to an industrial controller you can interface PCIe, USB buses etc for your DAQ instruments. We also offer this in our CompactRIO form factor where you would deploy the application to a controller/C series chassis similar to the compactDAQ you are using now in that it houses those C series modules but has much more to offer. I've put a few links below here if you would like to look into these products any further.

Is it possible to create a schedule in Labview . Example: i want to off the lights at 7pm and want it on at 8am. If there is can anyone teach, its for a school project. Im using labview 2011

Since this is a school project I recommend you do the work yourself. You will not learn asking others to do it for you. In addition, folks here will not do your homework for you. We are however more than wiling to answer specific questions for you. Post what you have done or tried and ask specific questions. I am confident you will get assistance.
And to answer your question, yes LabVIEW can be used to implement a scheduling program.

Looking for BC4J EJB deployment example

Hi,
I am looking for an very simple example project for BC4J deployed as EJB, including table definition, BC4J source files, and EJB client source files. I have previously successfully deployed the BC4J to Oracle8i JVM and OC4J, but currently struck at how to write the client application. I would like to know how to call my own remote methods other than working with ViewObjects directly.
Help needed.
Regards,
Patrick.

Maybe this will help:
In JServer, ejb inactivity timeout is controlled by property jbo.ejb.txntimeout which value is 60 (secs) by default.
JServer properties file is deployed as oracle/jbo/server/jboserver.properties, you can get it from jbomt.zip (you should create the same directory structure and a project, say jServerProps.jpr, containing the file).
Edit the file:
jbo.ejb.txntimeout=28800
jbo.ejb.txntype=local
, then deploy it as Classes and Java Stored Procedures to Oracle 8i.
To see effective values of jServer properties you have to set jbo.debugoutput=console in file oracle/jbo/common/Diagnostic.properties - from the same jbomt.zip.
It's better to include the file in the above jServerProps project and deploy at once with jboserver.properties.

Small Company looking for a LabVIEW consultant (remote consultant welcome)

Hello,
We are a small company looking for a LabVIEW consultant. This is about a 3-6 month project. The consultant must be familiar with NI hardware product as well. Please send me your resume/CV. In your email please state the following: years of experience, educational background, your hourly requirements, your location, and the amount of time you will be able to provide.
Please removes spaces on the email below.

I'm not sure if this is frequent on the NI forums, since I believe NI validates user information prior to issuing an account that allows them to post to the forum. But usernames (like mine) don't provide immediate identifications; you have to ask for it.
Apparently Job Scams have become more frequent. See the list of tips on the following site, (I have no relationship with this site. It just came up in a google search).
http://www.identityhawk.com/IdentityProtectionTips-inHonorof-LaborDay
5 Steps to Take Before Applying for a Job
1. Email - the company to get information about the job. Do not provide any personal information to them upfront.
2. Phone - speak to an official at the company and ask about the job. Be assured that it is legitimate.
3. Meet - at the company site to assure it is a real company. If you cannot meet, and the company is in your town, drive by to see the facility, (possibly using google maps to view the site).
4. Verify - see if you can find a person who has worked at the company or call a Chamber of Commerce of Better Business Bureau to assure the legitimacy of the company. Search online for legitimate information about the company, search online for any complaints of non-legitimacy. State Entity sites typically have the name of the company and how long they have been in business.
5. Apply - once you are assured the company is legitimate, it is safe to apply; but you should still not supply highly personal information like bank accounts until you are officially hired.

PCI-6251 into LABVIEW DAQ Assist block interruptions and resets

Signals being received from PCI-6251 into a LABVIEW DAQ Assist block interrupts and resets every 10 seconds after 1 minute of data acquisition. Would this be a memory buffer problem or is it something related to the hardware? I am using a BNC-2110 hardware connector. Please view the attached image.

Hey Peter,
Ahh, I understand the graph now! Hmm, this is very strange behavior. Instead of using the DAQ Assistant, try to use the explicit DAQmx VIs (see picture). You have more explicit control over what is going on with the DAQmx VIs and keep as much as you can out of the loop.

Incorrect AMUX/PCI6025 readings using Labview/DAQ

I have an AMUX64/PCI6025. Using my DVM, I measure the voltage at the AMUX screw terminals on various channels with correct readings obtained. Performing measurements with Labview/DAQ are incorrect. What is causing this?

Hello;
The first thing to double check is if the input mode is set accordainly with the connections made.
The best bet is to revisit the AMUX Users Manual and double check the connections you made with the ones shown in the manual. Furthermore, go to MAX and check the input mode of the DAQ device.
Everything must match.
In case you got everything accordainly with the manual, and you still see the same behavior, the problem is probably hardware related.
Hope this helps.
