How to create a feedback control system in labview with an integration block?

Hallo,
I design a model of a simple mechanic system composed by one damper, one mass and one spring.
I would simulate a free response of this mechanic system, but I don't be able to integrate the mechanic state in Labview.
Seeming that the integration block in LabView produce a wrong answer.
I've attached this model create in Labview 8.2.1.
Thanks in Advance

Michele,
First of all, when you are trying to develop a Dynamic Simulation, I strongly recommend that you use the LabVIEW Control Design and Simulation Module (http://sine.ni.com/nips/cds/view/p/lang/en/nid/203826), or, for LabVIEW 8.2.1, the LabVIEW Simulation Module. They allow you to develop your dynamic simulation natively in LabVIEW, specially in the case that you have feedback loop in your code (which is your case).
Now, looking at your program, I have several recommendations that would help you to better control your simulation. First, avoid using the Dynamic Datatype (Blue wire) in you simulation. For example, you are generating a Waveform inside the loop and you are just getting one element of the first batch. Probably, you want to generate only one element per iteration of the while loop and apply that to your equation. If that is the case, you should remove the "Simulation Signal" express VI and use the Point-by-point VI (located at Signal Processing Pallette). There you can also find an integration VI that allow you to define the sampling time for your application.
Also, the feedback node that you are using will introduce one sampling time to your simulation, which mean that, if your simulation and equations are not correctly setup to take that into account, your simulation will be incorrect. If you were using the Simulation Module, it would take care for your to do the correct integration, additional to allow using different solvers (like RK 4-5) to reduce the error on the integration.
Hope this helps. Let me know if you have more questions.

How to configure LabVIEW 2010 to communicate with GE Speedtronic Mark VI ethernet global data (EGD)

We want to use LabVIEW 2010 to send/receive floating points from LabVIEW 2010 to/from a network (192.168.101.xxx) that utilizes GE ethernet global data protocol (EGD).
The network has several HMI's running Cimplicity Plant Edition 4.01.
We can configure Cimplicity to read modbus points from LabVIEW using LabVIEW's multi-variable editor and a modbus slave library.
However, we cannot get the points from LabVIEW to read/write to the EGD protocol. Anyone ever run into this?

EGD is a UDP message (port 4746h) with a special header.See below for header structure (32 Bytes). Send UDP at constant rate. Limit user data to 1400 bytes. If you want to receive EGD data don't forget to increase the MaxSize connector on UDP receive to 1500. Are you using the a csv file or SDB Server to get tag names? Or manually entering tag names in cimplicity? This works much better than OPC because all parameters are contained in your labview executable. If you have a redundant cimplicity HMi Server send as Broadcast to the local subnet. All consumers will get the EGD telegram. Example IPA of 192.168.0.255. Server 1 IPA 192.168.0.1 and Server 2 IPA 192.168.0.2
Maybe to late for this project but would be a good upgrade or the next project.

Where can I get the example application FuzzyEx Car Backward Parking.vi from LabView?

Where can I get the example application FuzzyEx Car Backward Parking.vi from LabView? I've got the LabView 2009 and I don't find it.

First verify if you have the PID and Fuzzy Logic Toolkit installed. To do that, you can just look at the "Control Design and Simulation" palette and you should see PID Palette and Fuzzy Logic Palette available. If you do not see, you need to install this toolkit.
Second, in 2009 you have two options to access the example: you can directly open the example by using this address:
C:\Program Files\National Instruments\LabVIEW 2009\examples\control\fuzzy\Car Parking\FuzzyEx Car Backward Parking.vi
Or you can use the example finder and browse examples by going to: "Menu Help>>Find Examples" and "Toolkits and Modules>>PID and Fuzzy Logic Control>>Fuzzy Logic". yoiu should see "FuzzyEx Car Backward Parking".
Hope this helps.

Simple addition using 7 series Gen2 integrated block for PCIe for ZYNQ7000

Hi,
I have been trying to perform a simple addition program using 7 Series Gen2 Integrated block for PCIe 3.0.
Due to some issue in the design i am unable to proceed. Can anyone help me out on how the interface has to be done what are the necessary IPcores needed and the necessary driver to execute on the host machine.
Tool : Vivado 2014.4
Regards
Heramban

Hi,
Satish I have refered this document long time back. The issue is that this mode is making the FPGA standalone and its more complex. Am asking for a simple design where in i use 7 series integrated block and connect it to a custom IP core where it performs only addition. Generate bit stream, use a driver program (CPP file ). Execute in the host system. The CPP file will have the data to be executed. the FPGA reads the data from the HOST Machine (CPP file), executes and gives back the result in the terminal window (Host machine).

Integrating PuTTY into Labview

Hi, the LabView serial port session VIs do not communicate well with my stepper motors (they do not respond to 50% of the stepper motor commands - Excitron stepper motors) I want to create a VI that integrates the PuTTY serial port session manager into LabView so I can use PuTTY within LabView to control my motors. Can someone help please? I have found some mentioning of PIPES to do this but when I try to add it to my block diagram it says its unavailable - that source was from 2006 maybe there is another way now? I am running LabView 2010 for Windows Vista and I am not allowed to download anything over the internet from here - just FYI. Thanks Folks EE
Solved!
Go to Solution.

For some reason LabView doesnt recognize several commands for my stepper motors:
w (wake up)
i (display current settings)
P (display motion profile settings)
Q (run proiles x-y)
It obeys the others but I really need w, P and Q to work
PuTTY runs everything
I am using the basic serial port control VI (given in the examples) for the LabView control
I am using VISA
I was hoping integrating PuTTY would be easy and I could have full control in LabView
Perhaps I should be doing something different in LabView? I have only been programming for 3 months - it was new to me until then

How can I read pdf files from LabVIEW with different versions of Acrobat reader?

How can I read pdf files from LabVIEW with different versions of Acrobat reader?
I have made a LabVIEW program where I have possibility to read a PDF document. When I made this LabVIEW program it was Acrobat Reader 5.0.5 that was installed on the PC. Lather when the Acrobat Reader was upgraded to version 6.0, there was an error when VI tries to launch the LabVIEW program. And Later again when we upgraded to Acrobat Reader 7.0.5 I must again do some changes and rebuild the EXE files again
It isn't so very big job to do the changes in one single LabVIEW program, but we have built a lot of LabVIEW programs so this take time to due changes every time vi update Acrobat Reader. (We have build EXE files.)
The job is to right click the ActiveX container and Click "Insert ActiveX Object", then I can brows the computer for the new version of acrobat Reader. After this I must rebuild all the "methods" in the Activex call to make the VI executable again.
Is there a way to build LabVIEW program so I don't have to do this job every time we update Acrobat Reader?
This LabVIEW program is written in LabVIEW 6.1, but I se the problem is the same in LabVIEW 8.2.

Missing functionality if storing TDSM from LabVIEW

In DIAdem File Browser window is selected a file from DIAdem 11.0 Examples directory. File FFT_Expl_1 has icon with „tree pictogram“ and „tree pictogram“ can be expanded to see content of file (Time, Oscillation), bellow of File Browser is displayed many file properties. Anyway these properties are not displayed in DataPortal area?!? See picture 1.
Pict. 1
If I click on the file content in tree hiearchy channel Oscillation I can see properties for this channel and small graph with the signal preview. See picture 2.
Pict. 2
To make my own data I have used examples from LabVIEW 8.6. One of these is on the picture 3 TDMS - Express write data (time and frequency domain).vi.
Pict. 3
Every time I create TDMS data from LabVIEW 8.6 (it doesn’t matter which example I use) I see in DIAdem File Browser instead of tree icon the question mark icon?!? The question mark icon cannot be expanded by clicking on it?!? Also the amount of Shown properties is significantly lower in comparison with DIADem example files. Also no signal preview is displayed?!? How to proceed with LabVIEW and TDMS function to have possibilities of DIAdem example files?
Screenshots are in attached DOC file.
Please help

TDMS problems 2.doc ‏289 KB

Hello bilik,
Thank you for the great description of your problem, the Word document with the screen shots really helps with the troubleshooting.
It looks to me as if you haven't indexed the directory where your TDMS files are stored. The "?" icon indicates that the file is not indexed. If a file is not indexed, only a subset of the properties are shown in the dialogs.
The easiest way to solve this issue is to index the directory that contains you data files (your directory icons are grey, they should be yellow). This can be done by going to the directory (or subdirectory) in the DIAdem NAVIGATOR window, and right clocking on the directory name. From the context menu, select the function "Add Search Area ..." - your directory will then be transferred to the Search Areas part of the NAVIGATOR and all the TDMS files will be indexed. At the point the files will show all the properties and the "?" will disappear.
Let me know if that helped,

Is it possible to get back to the Try block from a Catch block?

I would like to perform validations on a config file. To do so, I have a method which will throw a MissingConfigException or an InvalidConfigException if something is missing or if something doesn't match a regex pattern. Although I have to do that with many different configs and I would like to go through all of them so that my error message will report all missing / incorrect configs at once instead of 1 at a time. Thus, I wanted to know if there would be any way I could do something like:
try {
     config.validate("ServerPort","\\d+");
     config.validate("MaxClients","\\d+");
} catch(MissingConfigException e) {
} catch(InvalidConfigException e) {
and have the catch block executed before going through the try block from where the exception was thrown.
Thanks in advance!

No, you can't jump back into the try. You can put your try/catch inside a loop though, so that if one fails, it will loop around and start a new try for the next one. Define a class that holds all the data you need to pass to validate, and make an array or List of those objects. Change or add a validate signature that takes this object, or just extract the strings from each one when you call validate.
ThingToValidate[] val = new ThingToValidate[] { new ThingToValidate("ServerPort", "\\d+"),
    new ThingToValidate("MaxClients", "\\d+"),
for (int ix = 0; ix < val.length; ix++) {
    try {
        config.validate(val[ix]);
        // OR
        config.validate(val[ix].getThingy, val[ix].getOtherThingy[]);
    catch (....) {
        // logger.warn("failed...");

You ought to have a listener somewhere that calls a function
to then set up the loaded swf. In that function you can do this
kind of thing:
var ldrmc:MovieClip;
function swfloaded (e:Event) {
ldrmc = null;
if (e.target.content is MovieClip) {
ldrmc = e.target.content as MovieClip;
If the swf was published for AS3, then ldrmc will end up
being a pointer to the root of the swf, and you can call functions
or set variables however you like. If it was an AS2 swf, ldrmc
would be null.
Inside the loaded swf you could try trace statements, to make
sure you're looking up the hierarchy far enough. Like this:
trace(MovieClip(parent.parent));
If that doesn't trace MainTimeLine, then maybe you're not
looking up far enough. Don't forget that the swf itself is in a
loader, and so may be one level down from where you thought it was.

Upgrading from LabVIEW 4

I'm currently upgrading an application from LabVIEW 4 to 2010 by way of 7.1. After opening the VIs in 7.1, I have several orphaned local variables and no idea what they might have been attached to.
Does anyone know how local variable behavior might have changed between 4 and 7.1 to cause this? I'm probably going to load 4 in a VM to check it out but thought this might be a known artifact that pops up when doing these types of upgrades.
Thanks!

as part of the evolution, so has the desire to use wires instead of Locals... (I hear shouts already )
If you know the control that it came from, is it within a section of the code where a wire would do the trick? Or if in a Loop, a nice Shift Register will carry the data. If within a Stacked Sequence Structure, then you may have to flatten it first.. Then clean up the code..
