Using the cFP controller with only LabVIEW and FIELDPOINT software but no LabVIEW RT
I have a cFP-2020 controller and cPF-AI-100 modules which I intend to use in a small project. I do have LabVIEW and FIELDPOINT software but I dont have LabWIEW RT software. Is it possible to use the cPF controller with only just LabVIEW? if yes, I would like to be advised how. Thanks
It is not possible to set up your system without Labview realtime module.
There are system integrators who can build a executable for you. You can search for a alliance member by using the following link; <a href="http://sine.ni.com/apps/utf8/niaa.search_display" target="_blank">http://sine.ni.com/apps/utf8/niaa.search_display</a> Or call your local NI branch office. But if you are planning to do more realtime projects in the future this wouldn't be costs effective.
Another option is to use compact fieldpoint pc controlled backplane (so there has to be a PC to control your compact fieldpoint system (not deterministic)). You can do this by using the compact fieldpoint ethernet backplane; <a href="http://sine.ni.com/nips/cds/view/p/lang/en/nid/202527" target="_blank">http://sine.ni.com/nips/cds/view/p/lang/en/nid/202527</a>

...How can i use labview.tlb to control Labview from an external application?
I've been told by a labview engineer that i could use the file
labview.tlb located in the labview install folder to control labview
from an external application (in my case, a C# app). I'm using Labview
6.1 under Windows 2000. This article confirms that:
"ActiveX and LabVIEW"
But i've not been able to find out how to use this file to achieve
what i want. I just want to be able to open/close labview, open/close

hellow,i have an instrument which do not have the labview driver,its
output signal is RS232,so can i use labview7.0 to read the signal?
Another possible option is to use the Instrument I/O Assistant. It is
an interactive tool that generates Instrument I/O and response parsing
code for you. It is very helpful in establishing a connection and
helping parse instrument response data. It is pretty high level and
basic, so if you want to utilize any special serial VISA functionality
it may not go as deep as you would like - but it can definitely help
get you started.

I have a project where I have to communicate between Labview and Siemens PLC.
Can anybody point me to correct direction (like reading material, Examples etc.) about how to do it?
The most obvious option is to use OPC to communicate between LabVIEW and the Siemens PLC. With just LabVIEW, you can use DataSocket for OPC, but if you have 100+ tags (IO points), you will be better off using the built-in OPC Client in LabVIEW-DSC.
Read up on OPC and LabVIEW-DSC for starters.
If this...Re: LabVIEW and LabVIEW RT?
I will try to illustrate it with an example since it all will depend on the type of application you would like to implement. Let's say you would like to implement an application where you log data, maybe exchange data with databases and you acquire a bunch of data points at a time not performing any type of control and where high determinism is not needed. In this case LabVIEW for Windows work great. If you on the other hand would like to implement a closed-loop application where you need high determinism and reliability and will acquire data point by point you would use LabVIEW RT which is an add-on to LabVIEW. I.e. you need LabVIEW + LabVIEW RT when developing an RT application.
...How to easily control multiple controls in labview
How can I easily control multiple controls with a single write to in Labview? For instance, I need to update 50 different boolean indicators. When I update them one at a time I use a cntrl refrence in my event structure, but outside of an event structure how can I easily cycle through them and update without making 50 local variables if I need to do them all at once?
Why don't you use an array of boolean indicators?
Have a look at the example attached <a href="http://forums.ni.com/ni/board/message?board.id=170&view=by_date_ascending&message.id=204328#M204328" target="_blank">here</a>, which can also be applied to this. You should usually avoid updating the value of a control from more than one place, though (unless it's something like initialization, where you can guarantee not having race conditions).
Other alternatives: using an array of booleans or using the picture control to create the image.
The way i use these booleans in my UI, I had to make them separate so I could arrange them in a user friendly way. And yes this is just for initialization so they won't be getting updated in two places at once.
...If i have a labview .vi file(and labview) but i want to open it in a computer that doesn't have labview, how would i do it??

...LabVIEW 8.0 changed a constant that was wired to a Case structure to a hidden control to maintain compatibility with LabVIEW 7.1 and earlier.
Y am i getting this msg?
This happened because "...LabVIEW does not compile code on the block diagram that does not execute. For example, LabVIEW does not compile any code that exists within the inactive subdiagrams of the Conditional Disable structure. In addition, LabVIEW does not compile code within a Case structure that has a constant wired to it that would not execute the case with the code..."In the other words, if you have case structure, which is wired to T/F constant, then prior to version 8.x both cases will be compiled. From version 8.x the only "executed" case will be compiled. So, LabVIEW replaces constant with control for ensure that both cases will be compiled as before.

I am a new user of LabVIEW.
I have been assigned to acquire a signal from a sensor at a car.
However, all these signals must be filtered.
But I am not sure, what type of filter most powerful. Besides, as I
know, different type of signal needs differenct type of filter.
Anybody can help me to solve my problems.
Your kind cooperation is highly appreciated.

...How do you control seperate motors with Labview through a remote control?
Forgive me if I am not typing the question correctly, or if it is a stupid question. I am only fourteen and only started learning about Labview.. I would appreciate all help possible. Thanks
What type of motors are you trying to control? How do you have them/plan to have them connected to your computer? When you say you want to control remotely, do you mean that you don't want them connected to a computer or that you want to communicate remotely through your computer (no cables)? The more information you can give the better help you will receive. Cheers
It would also be helpful to know what version of LabVIEW you are using. It's impressive that your starting to learn LabVIEW at such a young age, it will be challenging but worth it!
Well first off, thanks for asking questions to my questions, it helps me too :) The kind of motors I am trying to control are IFI Robotics Multi-Speed Motor Connect to PWM or RLY port (12 volt).. I am trying to remotely control it wirelessly, through an IFI Robotics Isaac16 EDU Robot Controller with 900MHz Short Range Radio Modem. Hope this Helps..
Oh yeah, and the version of LabView I am using is 8.5
It looks like your controller is designed to be programmed in BASIC. What you will need to do in order to control it with LabVIEW is figure out what the function calls are that will be required to activate your PMW signals etc.&a...Re: "Hi,I'm having problems controlling the Agilent E4422B Signal Generator with Labview.

If this driver supports multiple instrument models, then you will probably have to set the model in the default settings in MAX.
Ray FarmerMessage Edited by...Reading controller data into LabVIEW through serial connections to controllers?
I'd like to read data from environmental chamber controllers (System Plus) into LabVIEW through RS232 connections. Has anyone done something similar? I see interfacing with the serial controllers as the biggest obstacle and although not directly related to LabVIEW programming, I'm hoping someone here can give me some advice or resources on how best to do so now days. My first thought is to write a program with VB or C++ to act as a terminal and write the data to a text file for LabVIEW to poll. Aside from using Telix decades ago to work with BBSes, my only other serial experience consists of interfacing with a Kiethly multimeter using a C++ program. I would rather not use multiple PCs but I have never worked with more than one serial port on a computer before in the past. Perhaps LabVIEW itself already provides for multiple serial card communications (wouldn't that be perfect)? Any info would be great. Regards, Dave
LabVIEW has had support for serial communication for as long as I've used it and may have been part of version 1. It also supports multiple serial ports - built-in and USB->RS232. There are even a couple of shipping examples. I've not used this particular chamber but I've used several with serial connections. It's a matter of getting the programming manual and working through it if a driver does not al...Labview.lib was not calld from a labview process

...Installation of LabView 8 after LabView 6
Good afternoon everybody,
I've got a big problem with LabView. The fact is that I begin with this software...
I've just installed LabView 8 on a computer where LabView 6 was installed. Once the installation finished, I tried to launch a VI That was developped under the old version.
The problem is that two VI can't be found :
- AI Sample Channel.vi
- AI Acquire Waveform.vi
Therefore, I can't use anymore the program that was working before... What is the solution to get everything ok please ?
Thank you very much !

Tell me some good suggestion for this.
With warm regards,
The easiest way is to do a development distribution (File>>Save As.
If your needs are more complex, you can also try <a href="http://jkisoft.com/vipm/" target="_blank">VIPM</a>. I don't think the free version can do this, but it's worth it just for getting the OpenG code.
where i can find this development distribution ? is there option available in labview?
If you re using LV versions > 7.x, you can create an LLB by using the option Save As... in the Files menu.
You have to just open the top-level VI of that driver (or something) & go on to build the LLB. All other VIs will get added/bundled into it automatically. :smileyhappy:
In LV 7.x, I think it ll be under the Tools >> Build Source Distribution menu...

been working fine till yesterday. Since yesterday, it started crashing

screenshots of the Application Builder configuration window, the B.D of the vi
using DLL and that of the configuration window which pops up when i call the
DLL.I made a vi which performs FRA. I built its DLL.I have around 10
inputs. I output 3 one-dimensional arrays, and a string from the DLL.When i
