Re: SD6 Teleop Example Error 116

Unfortunately, that did not fix the problem. We are still getting that error 116 when we run robot main. The error only comes up after we start host main though. We posted this in the other thread, but...

Re: Time-loop at 1 MHz

Thank you for these precisions. My aim is to make some mesure through the DAQmx. I measure an intensity function of the displacement of a motor, so in order to have the most possible number of points,...

Re: Time-loop at 1 MHz

Why do you think you need a real time os for DAQmx. The time to acquire is a function of sample rate and number of requested samples. Just simple arithmetic. What device are you using?

Re: acquire a signal and put the value rms into an array every second

A timed loop is silly on Windows. You have the most precession by using a normal loop and setting the number of samples. Converting the evil dynamic data to an array is also silly. The mean is a scalar.

Re: Time-loop at 1 MHz

I use an old NI USB 6009 Altera DEO. The sample rate is 48kHz. To make me understand on the issue, here a little explanation: - a motor moves and then the signal on a photodiode is changing.I...

Re: Time-loop at 1 MHz

What you've shown doesn't show any need to have a while loop running at 1 MHz.  Set your DAQ assistant to continuous samples, and collect a large number, or all that is available.  Analyze and and it...

Re: Match pattern bug

John4u a écrit :Thank you. I tried with wiring too, it does not work. As I wrote already it works without the left bracket. It does not work only with the bracket. Here with I upload with default...

Re: Time-loop at 1 MHz

Sorry but i don't understand what you are saying, or more precisly i don't see how to apply it.  I understand for the merging of all the signals, I did it. My experience just takes 10 sec max, so...

Re: Time-loop at 1 MHz

There is nothing that stops the loop after 10 seconds and you are only writing the very last iteration to file. A regular loop is fine if you really limit it to 10 seconds but get rid of that silly...

Re: Plotting XY graph with two values and time

The radio data has three columns, the first two being some date/time format. What are the units of the second column?. The other file has two columns, the first is relative time in xx:yy format. What...

Re: SD6 Teleop issues

Okay, So I ran this VI to check and see if I am getting a connection with the NI 9870, and got the following output. I then unplugged the Motor Controller from the NI 9870, and ran it again, and the...

Re: SD6 Teleop issues

You are just floundering in the dark now because you aren't listening to what we are saying. That VI just tells you what ports exist on your PC.  It tells you nothing about whether something is...

Re: SD6 Teleop issues

I just unplugged the power to the NI 9870, and ran that VI again, and again got the same output. Clearly the NI 9870 isnt working. Anyone have any troubleshooting ideas?

Re: Plotting XY graph with two values and time

The second column of the radio data is the time in the format hr.min.sec, so the first time in the table is 00.05.29.

Re: SD6 Teleop issues

I thought that VI told me what ports were connected to the Robot. If I go to the NI Max Remote systems, it is giving me the exact same list of connections I had when the NI 9870 was plugged in. Is the...

Re: SD6 Teleop issues

Okay, I updated the VI with a timer, and still get the same error. Although I am not sure that I set up the timer correctly. Ravensfan would that be the correct way to set up a delay?

Re: Data acquisition triggered by CNC code

I've looked into the serial read and it is just was I was looking for, thanks for the advice! Just a couple of doubts:-Since the RS-232 is adaptated to plug into the PC through a USB, while setting up...
