Define independent for rpm and current control

Hello

I need assistance with labview. I am able the current, voltage and rpm of a pump connected to a control box. The control box is also connected to my DAQ. My requirement is that I would like to monitor the blood and fluctuations in current on an in labview waveform chart, once I run the file vi and monitor the number of laps when I start the pump. When I try to run the file vi before the pump starts, I get an error code "200284. I understand that the RPM in my vi counter does not receive signals and ends the program. How to set a control sparate for the display of the voltage and current regardless of whether if the pump is started or not? or how to set a control to monitor RPM display only when the pump is started and does not affect the voltage and current display part of the VI.

This may seem a bit complicated! Please give me your suggestions on how to do this!

Thank you

Rajesh

Looking at your code, the DAQ Assistant on the background is taking in the RPM data you are looking for. You can do a right click on the arrow to the left of the option "timeout (s)" at the bottom of the DAQ Assistant ExpressVI and select Create > Constant. This will create a constant within seconds that represents the DAQ Assistant time-out on entry. You can base the number on how long it will take the number of LAPS to enter to start.

.

It should look like the above, but you can change the time that the ExpressVI will wait for your needs.

  • Source for RH5 and 6 control

    We have two licenses for RH6 and four for RH5. Can we use the RoboSource COntrol 3 supplied with 6 HR under control of source code for projects both RH5 RH6?

    Looks like we should be able, but we're just starting on the use of RSC3 and details are difficult to find.

    Thanks for any help.

    Hi tojo45.

    I'm afraid you may have problems to get an answer on this one, because not many HR users using control source code and those who use the other tools of SS. However, I agree that, in theory, you should be OK as all the source control s/o will do is check in/out of the files. He shouldn't worry about what files they are. Also as RH6 and RHX5 are largely the same, you would have less risk than if you had RH7 licenses.

    I create backups of files RHX5 and RH6 and run a few tests. It will probably be the only test.

  • Variables for voltage and current on each component (for use in graphically the diagram)

    Hello

    I have a very simple circuit containing only a source of AC voltage and resistance of two series.

    I want to draw the voltage of the source and each resistance. I can't find any variable involves pre right now, I know I und came to the value of the resistance.

    for example

    UR1 = I * r1

    USource = I *(r1+r2)

    It's pretty boring... especially because that put in square brackets does not work.

    probably the cause variables containing itselfes media.

    hope you have an idea

    Hello

    The way that you have set in place now of things is correct. Multisim, as well as most of other circuit simulators, monitors the node voltages, no voltage drops. When you draw your diagram, Multisim assigns numeric node names to each node. That's why you see v(1) and v(2) and not something like V (R2). To find the voltage drop in R2, you will need to calculate V (2) v (1). To know the name of each of your nodes (also called threads), simply do the following:

    1. Click Options > properties sheet
    2. For option Net names, select Show all
    3. Click OK

    To make it easier for you, you can name a few nets to something that is easier to read. You can do this:

    1. Double-click on the net you want to rename (the net is the wire you drew connecting elements)
    2. Enter your name, preferred net in the space provided
    3. Click OK

    Hope that answered some of your questions.

    Here are some tips to help and troubleshoot battery issues.

    them and be careful). Batteries are old, or it could be a problem with the computer.

    New Lithium-Ion type battery usually last longer if you do not unload then less than 30%

  • scanning voltage and current measurement for Keithley 2400

    Dear all

    Hello

    can someone help me?

    Despite days nearlly10 I am option to find any program LabVIEW 2010 for sweeping the voltage and measure current who works with RS-232, I have a end not have nothing exept examples read single and multiple data. I tried to SmartData labview and changed a few prorgram gpib to RS - 232, but I couldn't.

    In another attempt to find a good VI "votltage scanning and current measurement" that work with RS-232 in labview 5.1.1. I have converted in 2008, but it takes old driver (ke24xx.dll) and do not work in my labview 2010 and I could ' t find older driver.

    My thesis project was halted in those 10 days, and I couldn't do anything for our keithley.

    Please helpe...

    in the following, I have attached these files:

    1.-first, what voltage scan that works with GPIB

    2 - Vi that I change the gpib for visa (rs232) port that I don't know why it doesn't work.

    3. it is Vi related to the "sweeping and current measurement votltage" that works with the RS-232, but it takes old dirver so I can't use it.

    4-slot-VI necessary for the implementation of program 3 (but there is no driver for these subVIs) was attached to the reply message of this post

    If any body has this program ("scan votltage and current measurement" running rs - 232) please send to me

    Thanks in advance.

    None of you attached the screws are the driver OR you spoke. There is no conversion required for this driver.

  • Whenever I try to change the settings for startup from the Control Panel, a pop up tells me that I need to activate Windows Defender and open

    I installed Microsoft Security Essentials today and I'm trying to edit startup programs. Whenever I try to change the settings for startup from the Control Panel, a pop up tells me that I need to activate Windows Defender and open.  However, most of the security will not allow Windows Defender be turned on and I want to change the startup parameters.  How can I accomplish this?

    Hello

    If you use Norton, AVG, Avira, Microsoft Security Essentials, McAfee, etc. the default action is for Windows Defender must be disabled, that these AntiVirus programs have their own Antispyware Applications.

    There is nothing to worry.

    Using both programs at the same time can cause system conflicts, etc.

    If you want to have additional protection against malware using the version FREE of Malwarebytes AntiMalware:

    http://www.Malwarebytes.org/products/malwarebytes_free

    And now edit startup in Vista without using Defender programs, use one of the following methods:

    "How to use MSCONFIG in Windows Vista"

    For Parental control, see the following: http://windows.microsoft.com/en-US/windows-vista/Set-up-Parental-Controls.  For each category, there is a tracking link that provides details on how to manage this particular aspect, including where are the lists and how block/allow access.

    Windows Live Family Safety 2011 allows you to manage remote parental control - but not really adds additional means to block or allow.  You can simply access computers remotely to do what parental controls can do this on the local PC.  Here's where to find this program: http://explore.live.com/windows-live-family-safety?os=other.

  • Scarcity and Dimension control for top performers of the cubes

    Hi all

    According to the Oracle support DOC-ID 985550.1 (Design of an OLAP Cube for performance and scalability) I'm little buit confused with indexing and Comporession diagram like statement below:

    "You describe the rarity/storage of the cube in Analytic Workspace Manager (AWM) in the storage tab when creating the cube. When you set, first place the dense dimensions in the composite. Order sparse dimensions with those of dimension members less first. "

    My question is: what do we mean by ' members of Dimension less? It is counted from number of levels in the dimension or the number of rows or number of attributes of size shot in AWM?
    Also how to qualify as a particular dimension could be expected?


    Thanks in advance,
    DxP

    The term ' members of dimension less ' in this context means the dimension with members less. For example, if you have defined and loaded a dimension called the PRODUCT, then the number of members is determined by

    SELECT count(*)
    FROM product_view
    

    If you work in 11.2, so this review is more important because the AW will reorganize the dimensions of himself. Most of the cubes I've seen have all dimensions marked as rare, so it is a good starting point.
