LCD with Labview

I was looking projects and I found this document on how to use LCD screens with LabVIEW, specifically on the myRIO platform. However, I was confused by the wiring schematic, since I am relatively new to using LabVIEW and the MyRIO platform. I understood the wiring diagram for everything except for J2. I did not know what J2 was. Could anyone explain what it is for me?
This is the document that I was looking at:
https://decibel.ni.com/content/docs/DOC-30485
Thank you in advance.

Hi, Jonathan
I think J2 is just a connector. This will connect to myRIO device.
You can look PCB picture, you will find J2 wire to the LCD and other pins.

Controlling a bcd 7 segment lcd with labview

I am pretty new to the Labview environment and am having a problem which involves converting a decimal value into its equivalent 4 digit binary number which then needs to trigger the appropriate boolean value to control a bcd 7 segment LCD.
For example, decimal 9 gets converted into 1001, and you have four boolean variables D,C,B,A, the converted binary nine needs to trigger D and A while leaving C and B off. Is this possible in Labview and if so any advice
Regards Shaun Oxley

To convert a decimal number to boolean I like to use the "Format to String" function with %b for a format specifier. A number goes in and a boolean "0101110..." string comes out. Once you've got the string, you can break it down by characters or turn it into an array of U8 to do lot of fun array stuff to it. I've attached a quick example that demonstrates a few tricks with strings and arrays. It will take a number and output the four LSBs in booleans for you. Fit for wiring to some DIO functions maybe!

Hi Guddan,
I created a RFC having a query which is taking a long time to execute. So i want to close RFC connection with portals which is via java connector(JCO) before that query and open the connction again after that query.
I guess i will need to understand your requirement a little more in detail, as i understand you have an RFC which has a query within to fetch some data and is taking a long time to do so. In the meantime you don't want to keep the connection open?
My question would be, Is the role of this RFC to only execute the query and fetch the data or does it do something else?
If it does other things and these are independent of the query execution, then you can span a parallel call within the RFC to execute the query and in the meantime the RFC does the other things (or vice versa) hence reducing the overall time taken.
If the sole purpose of this RFC is to execute the query, then you will not be able(i mean to say there is no simple and direct way of doing this) to close the connection after the Query is started and re-establish the connection after its execution, for a simple reason that - how will you know if the query has completed it's execution, so that you can establish the connection back.
Alternate solutions, make this a two way asynchronous call, 1) You invoke the RFC asynchronously and close the connection, the RFC in turn will execute the query and transfer the data to JCO via another RFC call.
If this needs to be a synchronous call, then you will need to optimize the query to its best.

Chen

Lost ActiveX connection with LabVIEW server

I have called LabVIEW in TestStand and tried to execute the test cases .
While executing I got the following error: ( Lost ActiveX connection with LabVIEW server.
The LabVIEW adapter will try to reconnect on the next execution attempt.-18001; An error occurred accessing the LabVIEW ActiveX automation server.).

Same error. Is anyone from NI going to bother commenting on this? It's been >8 months...

How can I create a scene and move 3D models in INSIGHT with Labview?

Hi!
I need some help in doing a LabView application. What i have to do is controlling a 3D model represented in Insight with Labview. Something similar like the six-axis-robot example. I follow the insight configuration wizard, but nothing moves. Comparing the ".cis" files in my program and the one from the six-axis-robot, i found that in the six-axis-robot file contains something called localsystem and the one made by me, doesn't. Can be this the problem? How can I make it work? I would need some kind of step-by-step response, because i'am a beginner with Insight and 3D models. Thanks in advance!
Regards!
Juan

Thanks for the advice!
I'm actually finding the next problem. Although in my VRML file the objects are defined separately in a jerarchy tree, I can't move(rotate, translate) each object individually. I have noticed that when i define a new local system and asign it the points of the object i want move in the way you explain (right click, and then dragging the points to the new local axis), the movement of this object is dependent of the other local systems i have defined for other objects , specially if the slave nodes of the .cis file has a lower numeration than the object i want to move. The fact is, the movements assigned , for example to the nodes 1 to 100, will affect to the rest of the nodes if i also define for the rest of the nodes other movements. How can i solve this? I send you my .cis file, just in case my explanation is not enough clear. In this file you can see that movements assigned to nodes 1 to 4078, will also affect to nodes 4079 to 7168, and what i would like to do is define a movement for each obeject independently.
Thanks again!

Excel with Labview 6?

I'm trying to get Excel '97 to work with Labview 6.02, but I'm always receiving error message: -2147319784: "old format or invalid type library". I modified windows registry as told in LV knowledgebase. After that I could see Excel components in ActiveX pull down menus. I have tried to run demos such as "Open Excel And Make visible.vi" but they always output the error message. I have tried this with both Windows 2000 and NT. Other programmes, for instance MS Access, seem to work fine. What is the catch?

Anders,
You have run into a special case of the problem that actually has a work around for it. However, you will have to contact LabVIEW technical support to obtain the temporary fix since they need to keep track of all the people with this special case.

Hi Leo22,
Does this error occur if you use any of the example programs that come shipped with LabVIEW? I would try opening one of the examples that write data to Word and see if those give you an error. Also, have you tried just putting down a New Report.VI and change the report type to Word? If this simple vi (that's all you need to open Word) breaks, I would check to see if there are any instances of Word still open. Check the task manager to see if any word processes are still open. There should not be a problem accessing Word 2003 from LabVIEW 7.0. If neither of these solutions work, please give some more detail about your application and we can research further. Thanks!

Calling a VI which uses "system exec.vi" with LabVIEW run-time engine as adapter

Hi,
My TestStand sequence calls a VI which includes a call to "system exec.vi". When I try to load it in TestStand and if LabVIEW adapter is set to run-time engine, I get an error message "Unable to load Vi...". If I switch the adapter to "Development system", then it works fine.
Is there any way to use "system exec.vi" in a VI which is called in TestStand with LabVIEW run-time ?
Thanks,
Alex

How do you use Synergy 7.1 with LabVIEW?

My company has reciently installed and configured IBM Rational Synergy 7.1 to be used as our Source Code Control tool. I have installed the appropriate Microsoft Source Code Control Interface so that Synergy will show up in LabVIEW and it does show up in the "Source Control" options window.
However when I select Synergy as my source control tool it does the following:
1. Brings up the login window - I am able to login with no problem
2. Brings up a dialog allowing me to select the project to work on, and after I select the project I get two errors...
one from Synergy: "The workspace/project you want to add to IBM Rational Synergy is not under the work area path 'C:\xxx"
(where xxx is my work area for the Synergy project I selected)
then one from LabVIEW: "Error -2941 occured at prefPage_Source Control.vi An error occured trying to get the source control project path. Possible reasons: LabVIEW: The source control provider does not support the specified operation."
I first tried this on an earlier version of Synergy that matched what is being used in:
http://digital.ni.com/public.nsf/allkb/16D37CCC8659123F8625720500087DB4
But I was getting pretty much the same errors back then too. It seems like it should work in LabVIEW, I just have no idea what I am doing wrong!
Anyone out there successfully using LabVIEW with Synergy????
Thanks,
Trevor.

In theory if a source control provider supports the Microsoft SCC interface, it *should* work with LabVIEW. In practice, each provider has custom implementation that sometimes causes problems when trying to configure the provider from LabVIEW. One sticking point for many providers is the expectation or assumption that an IDE will use some concept of a "project" and therefore pass data associated with that project to the provider. LabVIEW does not enforce that concept but does pass valid information.
Synergy was tested back when it was a Telelogic product. It was difficult to configure and required exact steps to get it to work correctly. The linked knowledge base were steps taken that worked for a few customer setups. It's possible that on other Synergy setups the exact steps may not work. Also, you might check to make sure you try to configure existing Synergy projects and not try to create new ones from LabVIEW.
The error you mentioned seems to imply that some data is not supported by Synergy. I am not sure if Synergy would be able to track down the issue, but I would recommend contacting them to see if they can pinpoint what data LabVIEW is sending is not valid.

How can I create a new excel workbook only with labview

I'm trying to create a new excel workbook only with labview but I can't find the file in the hard disk.
Someone knows?

Create new WB with LV.vi ‏18 KB

You are not using the correct mechanism. Pull up the Example Finder in LabVIEW, click on the "Search" tab, and enter "Excel". Look for an example called "Write Table to XL". Use this as a starting point for creating new workbooks and adding data to it.
Note: on disk the example is at <LabVIEW install directory>\examples\comm\ExcelExamples.llb.

Windows 7 Compatability with Labview 8.0 and missing files while interfacing the FPGA with LV

I am trying to use an FPGA (PCI-7830R) with Labview 8.0. The computer has Windows 7 OS. I installed LV 8.0 in the proper order with the FPGA Module and labview is able to see the FPGA when I open a .lvproj (the FPGA is in the tree) however there is a warning symbol next to the FPGA selection and when I try to open a .vi file that is used on the other stations in my lab (it works on all the other stations), labview is unable to find a whole bunch of files. There are some pictures.
Missing File (there are a bunch more but this is the fist one).

According to this LabVIEW Compatibility LabVIEW 8.0 is NOT compatible with Windows 7

Creation of step (by Teststand) with LabView

I created a sequence with TestStand, I would like to insert a step in it but with labview.
The problem occurs on the level from the NewStep method and its StepTypeName parameter.
This parameter is of type String, I tried to enter several string but unless result.
The error appearing is "Step type not found in type list".
In the help file of TestStand, it is said that "the step type must already be in memory",
but I don't more understand it.
Can you help me?

Hi,
I think you have to load the TypePaletteFiles first.
Please take a look at the example from the link below.

Is it possible to view VIs remotely on windows 7 if VI was built with LabView 8.2?

So I know i'm probably dealing with software compatibility issues here, BUT, I wanted to make sure every option was exhausted before considering the idea of upgrades.
Im using LabView full development system 8.2 on windows XP 32bit os. Currently, I run into no issues when controling or building VIs on my computer. Problems do occur when trying to control VIs on a remote computer with windows 7. That computer has run-time 8.2.1 installed on it. For the most part it works best to just view the VIs, and not interact or control too much. More specifically, the VI will freeze once interacting with a control that is intended to pop up a two button dialogue box. I'm sure there are a lot more issues with using run-time 8.2.1 on a windows 7 computer; that one in particular is just the only one i've experienced.
In all efforts to avoid what could eventually be an unavoidable situation where an upgrade is necessary, is there a way to remotely control (on windows 7) a VI front panel that was built with labview 8.2?

Thank you for the response. Just to preface, I am fairly new to LabView so pardon my potentially "stupid" questions. Here's my process in a nut shell: VI programs are created on our server computer and then published for web with the "web publishing tool...". The html page created is then put on a main page with all other created VIs and are then viewed on other computers that are part of the network via ip address.
I was under the impression the LabView run-time engine enabled remote computers to view and control these VIs. Could be wrong? After downloading and installing run-time 8.2.1 (since vi's were created with labview 8.2), those computers are able to enter the ip address and navigate to the main page to control the web published vi's. The issue is with the computer that has windows 7. I know run-time 8.2.1 isn't necessarily compatible with windows 7, but it does seem to run the vi on a pretty minimal level. I run into problems on that computer when hitting particular controls that are wired to be more complex than just a simple boolean.
Just to provide a visual, I attached an image of one of the scenarios where it will freeze up on the windows 7 computer. This is how the VI should normally function; however, before the dialogue box even pops up after clicking a valve control, it freezes.
I didn't even consider VNC or Remote Desktop up to this point. Thank you for that idea. I'll definitely look into that as an alternative.
