Re: Is neccesary to initialize an array of indicators to be able to show my results?
Thank you!! So, the problem is the function that I am using!! If I want to write a value in an array, and before doing this I don't want to write a default value. What function can I use? I know that Insert Into array doesn't work properly in my application! Thanks in advance! Graci
Hi!!I have some problems with the synchronization of my...
Hi!!I have some problems with the synchronization of my system, and I don=B4t know how I can solve this! My system consists of differents vi=B4s.Some of them are used to read analogic inputs and digital inputs, using the serial port. The values that I read, go through differents vi to be proccesed, and at the end, these values are written in a file, all the values in the same file. My problems of synchronization are: 1. I have one vi per input, and all of them use the same serial port. How can I synchronize them to avoid serial port conflicts? (using queues??) And how can I do, to get differents number of samples/sg with every vi? I have to introduce them in differents loops? 2. The other problem is that, for example, I want to read 8 samples/ s but I only want to write two samples every second. How can I do to avoid stoping the data flow? Maybe, my problem is that I want to see the system like one block, and I am ignoring that, although all the system works like a block, every part works using a different "speed". I don=B4t know how tools can I use to combine two ideas, working like an only system( data dependence, some vis need the data of others vi to be able to work) and working getting differents numbers of samples/s. I have seen that there are synchronization vis. I am going to glance at them, maybe I find something interesting but I amsure that your help will be very useful? Thanks in advanced!! Graci
Labview Linux!!
Hello everybody, I need to develop an application in LabVIEW 7 and it should be able to launch the LabVIEW programming interface, work with it and finally create another application using the Application Builder. For example, the application could have some buttons: 1) Launch LabVIEW 2) Save VI 3) Open VI 4) Compile VI and generate exe file .. We are working in Linux (Debian-KDE). How can we start? Vi server maybe? Thanks!
Re: LabVIEW on embedded PC's
Hi Yves! I know that the date of your answer is 2001 but I hope you can answer me! I am trying to run a headless vi (exe) on embedded PC that works over Linux. This PC is TS5500 Technology Systems, and my problem is that this PC hasn't graphic card, so I can't use an X server and I can't run my vi (exe). Do you know if there is any alternative solution? Your answer will be enormously useful for me! Thanks in advanced! Graci
Is neccesary to initialize an array of indicators to be able to show my results?
I am working using Labview 7, and I have a problem when I have to show my results in an boolean indicators array. The problem is that I have to initialize the array to see the results. Is it normal or am I doing something wrong?Has it any solution? Thanks in advanced. Graci
Hi!!how can I build a vi with every number of inputs?
The vi I want to build is a little "strange" , I am going to try to explain the basic idea!! I need a vi with every number of inputs, so, maybe my vi has 2 inputs or 50 inputs. I know that a vi has a limited number of terminals (28), so , I thought that I had to use an array to avoid limit the number of inputs and outputs. But the problem is that I want to connect my inputs separately , no using an array. I suppose that my explanation is not very good! I want to build something similar to the vi "Build an array" . It is a vi that has every number of inputs, this example is to explain the idea. I dont know if it is possible doing something similar, because depending on the number of inputs the block diagram will change! Thanks in advanced!! Graci

Does anyone know if there is anyway to build an executable in Linux and this executable run in every Linux version? Hi!! I am working using Linux. I have built the executable in a PC with a version of Linux. And I tried to run this exe. in other PC that works over other version of Linux, an older version, and the result hasn't been very good. I think that Labview has to use some Linux libraries when build the executable ( I am using VISA vi). It is not possible to build the executable in the PC that has the "poor" version of Linux, because it is a embedded PC. I am asking if it is possible to build the executable in a "way" that lets us works in every version of Linux!! Thank you!! Graci
Hi!!Does anyone know how can I programm a vi to launch Labview in Linux?
I want to build an aplication to launch Labview. But the problem is that I am working with Linux, so I can't use Active X to do that. How can I do it? Is there VI server in Labview for Linux? and if is there Vi server, how can I use this, to launch Labview? Thanks!! Graci

hi!!!I need your help!! Does anyone know if there is any Modbus lib or Modbus driver to use this en Labview BUT in LINUX? I am using Labview to comunicate with ADAM modules, but I want to comunicate with them using Modbus protocol. I don=B4t want to use "ADAM protocol" ASCII comands that the modules can understand. So I need a Modbus driver or Modbus libraries. The PROBLEM is that I am using LINUX I am looking forward to your answer!! Graci
Re: Has anyone written a driver to comunicate with an ADAM 4000...
Thank you for your answer!! But the problem is that I am working using Linux, so I couldnt use the driver And I cant open vi_adam_4000.html!!! Do you have any idea? ciao! Graci
Has anyone written a driver to comunicate with an ADAM 4000...
Has anyone written a driver to comunicate with an ADAM 4000 module using Modbus portocol over RS485? Hi! I am trying to comunicate with an ADAM 4000 (4068) module using Modbus protocol. I send the message through the serial port RS232 because I am using other ADAM module that converts RS232 to RS485, so RS485 is not a problem for me!!I think that the problem is the frame that I am sending!!!The ADAM module doesnt respond me Has anyone worked with this protocol I am looking forward to your answer ;)!!! I need help!!! Ciao!! Graci
Re: Hi!!!I need help!!I am desperated!!!The serial port makes me become crazy!!!
Hi JLV!! Thank you for your solution, but this vi works . The vi that doesn=B4t works is entrada_analogica.vi, the first one that I attached. And the problem is in the the frame 1(0...1), when I write other command and I try to read the answer, the answer is one byte,and I have to receive 10 bytes, so the vi stops in the while loop and I have to abort the execution. Do you have any idea to solve this? Thank you!! Graci
Re: Hi!!!I need help!!I am desperated!!!The serial port makes me become crazy!!!
I have tried this, but it sometimes works and other times not, so , it is not a good solution for me!! Thank you!! Graci
hi!!!How can I change the options in a VI express?
I want to scale a signal, and I am using the vi express "Scaling and Mapping". ButI want to control the differents "options" that I can choose, linear scale, slope...How can I do it? I don=B4t know if it is possible in a vi Express. I know that I can change the properties of controls and indicators using properties nodes, but I thing that it doesn=B4t work in this case, but I am not sure Thank you!!! Graci

Hello!!!I need to read some data from the serial port and processing these, at the same time I want to see the process that I am doing. I read the data without problems, and I see them using Waveform graph, the problem is that I want to see the real time stamps, but in the graph appears 2:00:00,000 and 01/01/04, so the date and the time is wrong :(!! Can I change this? I am thinking that the problem is that I have to adquire the data and the time stamps ( using Get date/time) and after, I have to represent both!!! Thanks!!!
I want to build an array using the data that I get through the serial port
I am reading data through the serial port, but I want to buffer these data. I have seen a function, but i think that i can use this if I am reading data from I/O intrument, so I don=B4t how can I fill an array, with the data that I am reading!!! Thank you!!!
Re: Hola!!!Yesterday, I asked a question about serial port...
Dear Mads; I have put the "Bytes at port" inside the while loop, and surprise!!!it works, but in one vi it works properly, and in another vi it doesn=B4t work, and the programm is similar, so I am thinking that it depends on the command that I sent.So, I will see if I can find a solution!! Thank you for everything!! Ciao!!!

Does Labview have any function similar to "ProcessSystemEvents"in Labwindows CVI?
I have written a comand through the serial port, and I doesn=B4t receive the answer. If I execute the programm step by step, I don=B4t have any problem but if the program runs i don=B4t get the answer!!!It is not a problem of the bytes that I write and receive, i have used the function "Visa Bytes at Serial Port"!!I have used th function "wait" but it doesn=B4t worki have used a Flat sequence but it hasn=B4t solved the problem!!so, i don=B4t know what i can do!!!

I write a comand using the serial port but when I read the answer I have an error of time out!!How can i solve this? When I have had this problem using LabwindowsCVI, i have solved this using a function called "ProcessSystemEvents" that executes all the "hang"events before reading the asnwer. Can I fing something similar in Labview Thank you Ciao!!!

I have two number which representation is binary(8 digits each one)but I want to work with these numbers using these like an array of 0 and 1( 16 elements, 1D), how can i do it? I did it in a way that I think that it is not very "elegant". I have 2 strings that contain an hex number, i have passed these strings to a number using "Hexadecimal string to Number", i had 2 numbers , and i can use a binary representation for these, but! i want to work with an array that contains the bits that form these numbers , i did it using , 1=BA"number to boolean array" and 2=BA "boolean to (0, 1)" but in my opinion ,it is very complicated isn=B4t it??? other way to do it??? thank you
What differences are between VI templates and VI?

I used to working with Labwindow CVI and i would like to know how can i use the commands "loadpanel" and "Displaypanel " in Labview. Using Invoke Nodes? I want to make another panel appears and runs, but i don=B4t want to use a subpanel. So, i would like to use somenthing similar to Loadpanel and Displaypanel, that you can use in Labwindows CVI, but in Labview, is ti possible?I hope your answers, thank you!!!
