Hi, i'm using serial communication for my gui.i,m able to transmit data from pc to controller but how can we get acknowledgment from controller to pc.please help me. Thanking you, harika.

Hi, i'm developing one GUI for motion controller.I'm using serial communication as sub vi,so that i can send packet format for each control.but ,after running main vi and selecting any control,the corresponding data is transmitted and it is strucked.I want vi without opening front panel of serial communication and data has to be transmitted for each n every control.It is for pc to pc communication. The vi is attached hare. Thanking you, Harika pothu.

hi, how can we convert an vi to exe file.please help me out. Thanking you, Harika.

hi, i am working with nmclib dll.using this,i'm opening one port and after that serial communication takes place then closing port.but when i'm opening port it shows an error.so.can any one help out please. Thanking you, Harika pothu

hi i tried as u suggested,but i didn't get the plot.i attached my plot.so,whenever the phase diff is less than -90 deg the plot should be continued and other than that plot should be stopped.plz help me out. thanks. harika.

hi i am trying to compare the varying phase against a constant value and whenever the varying phase is greater or equal to that constant,the plot should be stopped.if it is less than that constant plot should be continues.the plot is freq along x-axis and phase is along y-axis.i am using comparison function in case structure but i don't know how to plot whenever phase is less than the value.i am getting white tunnels at the out side. thanks. Harika.

hi thanks for ur response. HARIKA

Hi I am new to labview, I want to plot point by point xy graph, but i am not getting it which I attached. so please help me how to plot frequency vs phase graph. thanks harika....

Hi Harika, Could you be more specific in your question? For example, do you want to know how to have a second axis displayed or is your question about how to calculate the phase variance? If you think a screenshot of your code or a VI would help us understand better your problem, please post it as well. hi sir,thank you for ur response.i am very new to labview.i am generating two sinusoidal signals with same amplitude but different frequencies i.e.,i am keeping first signal freq as constant(40 hz) and varying second signal freq manually upto 40hz. i am intended to plot the continuous xy graph for freq difference on x-axis and phase difference on y-axis,whenever i will get phase difference of -90 deg the continuous graph should be stopped. i need to know how to generate automatical variation of signal frequency.actually i am not getting xy graph continuously for every change of frequency.it is showing one value as a point at that instatent.i am also not getting stopped graph for phase diff of -90deg. :question:

normally the graph showing the variation for only for particular value.i want the graph for phase difference for two signals for all values at a time by varying the frequency(0-40HZ) difference.
