  1. i'm a little bit confuse about this.. can you show me what steps must i do to watch a simple vi from another PC ,via internet? web publishing tool gives me an address like http://mypc/simple.vi but this address is a local . maybe i must change "mypc" to current ip address like 82.210.125.150??
  2. thank you very much! i will check the file , but fisrt i have to install 8.6v because my labview is an older version.
  3. hello , is it possible to watch a VI from internet? i made a simple VI and i want to watch it from everywhere. i have done some tries without result. can you help me?
  4. yes,i have made a test before,run in Labview or Hyper. suddenly,i have no contact with software!!! anyway, i will search for something else ...
  5. problems never ends!! well, i download a program-spy-watch-serial data. i have done a communication multi and software and i wanted to saw what data sends-recieves. now, software doesn't let me communicate with multi!!! says , (check COM1 or the unit)
  6. i don't send any command. actually , when i press some "letter" my PC stucks.<br>that i'm a doing is to connect them and wait receive data.<br>normally, multimeter sends all time data over 232. thus, if i connect multi with PC i will can see data. either hyperterminal or VI can not see anything. multi and software dont have problems.
  7. i didn't make any specific code on LABVIEW. i open the example basic serial read and write.vi and just try to communicate i also try on hyperterminal without result. model of multimeter (UNI-T UT70D) i did as operating manual said: Baud rate 9600 start bit 1 (always 0) stop bit 1 (always 1) data bits 8 parity none ................................ is there anything else to check?
  8. hello ... i have bought a multimeter and i tried to upload values to Labview this multimeter has own software to read and represent values But i did an effort to build my own software to take and show values. actually , i made the simpliest communicate on RS232 without result. do you think that data have a codification or something? is there anyone who did that before? if you want i can upload manual of multimeter.
  9. i'm very happy to see you again!!!!
  10. thanks for answer Dan!! i send from my microcontroller 10 periods = 250 values. when labview takes the last value,then appears the result and wait for another 250 values .my problem is that i don't want to run continusly i want to take 250 values ,calculate ,and then wait to take other 250 values. if i can reset tables every 250 values ??? one thought is to add to more cases ,as example "S" for beginning and "W" at the end at the "S" i will do ENABLE table and at "W" i will do RESET table... is it possible to do this automatically??? i hope to understand... 3000000 is "byte to read " is very high because data are too many! when i put it at smaller value i have bad signals!!
  11. Hi everyone, I am trying to finish my project with pic and labview through serial port and i have been stucked in something and i want your help. I use cases to saperate three chanels that i am taking from the pic and send them from the serial port to labview. My problem is that i want the program to start making calculations when i send it one letter for example "S" (as start), S CaseA CaseB CaseC CaseA CaseB CaseC (pause_labview wait for the next start) S CaseA CaseB CaseC CaseA CaseB CaseC......somethink like this. Furtheremore as you can see i have to calculate the rms value of the three chanels. As you can see the value of rms is always changing but i want to see this value every 250 new values of my signal.

    estimate Power

    hello .... i send from microcontroller via rs232 2 signals (take them from sensors) Volt and Current ..i can plot them and store them.. so far so good..no problem! i can also estimate reactive power S=P + iQ the problem is how i estimate average POWER (real) one idea is to multiply V*I (any sample) then pass to Low Pass Filter at 5Hz and that i receive is real power (sounds simple!) i test it on simulate signals and works great but labview don't recognize my two "signals" as signals! what can i do for this? do you have any idea?
  13. i will use a PIC microcontrolle that supports USB2.0 hardware.i will make software of USB protocal . so, output from PIC will be a usb cable (not rs232 to usb converter) and i 'll plug it to one of my usb2.0 port on my computer in that case, will LABVIEW recognise this PORT as serial(COM4 for example) or usb? can i increase speed that way? thanks for answer!!
  14. hello everybody.. i made a project based on microcontroller and communicate with 232. my baud rate is at 115200bps and proved to be very poor for what i want to do. i'm thinking to change my communication to usb2.0 (microcontroller support ) my question is .. if i do this ,do i have to change my program on labview? i mean .. now i select COM1 to communicate with micro after change this the only thing i have to do is to change COM1 to COM4 for example? and increase baud rate or i have to do more things on program>?

    serial communicate

    thanks a lot DanDefriese,again! i upload an example just to see how represent the data. this time i put 6 different graphs and i can see all plotting.
