can't find SIM zero cross detect for integrator vector. VI

[JAntonio]

Hello everybody, I am trying to get the Quanser NI-ELVIS - "DC MOTOR CONTROL TRAINER" to start working, but whenever I want to start the program it keeps asking me to find the following VI files:

Zero cross detect for integrator

SIM limit reset state tables (scalar)

.

.

.

The list continues... I have looked everywhere in the CD that came with this hardware(QUANSER NI-ELVIS trainer) and I haven't found it....

Please help...what steps am I missing? I have downloaded all the files in my computer and the hardware is connected?

Any help is greatly appreciated. Thank you.

JAntonio,

You are missing the "Simulation Module", which is a separate installation CD. If you have Developer Suite, your University has Campus License, or you have LabVIEW Student Edition, you can have access to this product from National Instruments. Otherwise you need to purchase this additional plug-in.

The best way to know if you have this Module is to talk to your sales representative to know what or how to have access to this Module.

Thank you. I have installed the "Simulation Module" located in the "NI ACADEMIC SITE LICENSE, tried to run the "QNET_DCMCT_Lab 01_Speed Control_Demo" I am still getting the same window asking  me to get the "SIM zero cross detect for integrator vector. VI" file...

If I keep  on going without this file, another windows pops up asking for the "SIM limit reset state tables"....I also loaded some other simulation tool kits, the DSP module and I tried to include everything I could that seemed pertinent, but I just kept getting the same problems I had before...

Any suggestions? I asked for technical help at school and they installed the "simulation module" as well. I have everything powered up, the hardware and the connections seem to be working properly, but I cannot even initialize or run the DEMO for lab 01.

Please help.

Thank you

JAntonio,

What is the version of LabVIEW and Simulation that you are using? If you 8.2, it would be better to download the latest version 8.2.1 from our website. There was a problem with 8.2 that would be asking for several VIs (about 10, depending of the functions that you have). If you try just Cancel each request, you can also load the application. However, you have to wait until it asks for the functions.

Another problem is related to installation of several versions of LabVIEW on the same machine. If this is the case, please let me know what versions that you have and I could advice further.

Thank you for your pacience.

Thank you very much for helping me.  I have the 8.2 LabVIEW version installed in the computer I am using for the QUANSER_DC_MOTOR TRAINER. There are no other LabVIEW versions installed in this computer. I have attached a WORD document to this message with screenshots of the errors I am getting when trying to run the application in the NI - ELVIS.

I did cancel each request, but at the end it still did not work. If I need to download the 8.2.1 version of LabVIEW where and how do I do it? Would I be able to get the files I need to using this version?

I thank you very much again for helping me. I hope I can get this to start working.

Sincerely

Antonio Mendoza

Antonio,

I was not able to see if you have NI-Elvis installed on your machine or not. This is a separate installation and it is not available, it will not work. Do you have NI-Elvis installed?

The upgrade to 8.2.1 will help you to avoid searching files. You can download the latest LabVIEW 8.2.1 and Simulation 8.2.1 from the web:

http://digital.ni.com/public.nsf/allkb/222FADA12273B23E862572610029A6E6

http://digital.ni.com/public.nsf/allkb/BAB5EB4D5E64D71E86257261002BCFD1

Notice that we have a problem in doing this process and you have to repair a component shipping in LabVIEW called Simulation.msi. The complete instructions can be found in:

http://digital.ni.com/public.nsf/allkb/C4B6EF55C6948A27862572B30068BF91

After you have NI-Elvis and LV 8.2.1 with Sim 8.2.1, in some cases, it is worth to mass compile your application before open it.

Let me know if you still having problems.

Thank you again for helping me. I do have the NI-ELVIS installed in my computer...it is actually a lab with more than 20 computers that have this unit installed and that I am trying to get the QUANSER board started.

I clicked on both of the links, but I could not find a place to download LabVIEW 8.2.1 on the first link, I am using LabVIEW 8.2 in all the computers...I downloaded the simulation module located in the second link you provided me with :  ( Drivers and Updates: LabVIEW Simulation Module 8.2.1 ). Everything went like you said...the program did not ask for any files after I repaired the Simulation.msi (\Products\LabVIEW_Simulation_Core_Shared\simulation.msi.) and mass compiled the files. However, it still did not work...I keep getting the "run" icon all broken and keeps telling me that some files have changed and that asks me if I want to save the changes. I clicked "no" since I had errors and that broken icon...

What can I do?

Thank you very much again

JAntonio,

You have two options here: You can contact you Sales Representative or Applications Engineer to obtain your Upgrade to LabVIEW 8.2.1. This SIM 8.2.1 need this latest LabVIEW to work properly and, as you know, several fixes were introduced in this version on LabVIEW alone. So, that is the most recommended path.

Your second option is to stay in LabVIEW 8.2 and you need to mass compile the Simulation folder and Control Design folder to 8.2. To do that you have to launch Mass Compile, that can be found in (Tools>> Advanced >> Mass Compile) and you should appoint to the following paths:

1) c:\Program Files\National Instruments\LabVIEW 8.2\vi.lib\simulation

2) c:\Program Files\National Instruments\LabVIEW 8.2\vi.lib\addons\Control Design

This will avoid the question if you want to save changed files. After that, I recomment you to Mass Compile also your Quanser Demos. If after that you still with broken arrow, just drop a constant or delete/rewire any wire in each subsystem that you have in your demo and, in the end, press the run button even if it looks broken. This is a know issue that you can read in our Readme files shipping with Simulation Update.

Even if you have LabVIEW 8.2.1, I also recommend mass compile Control Design and your application.

Lets see if that would help you!
