Converting csv files to signals

[ishironagasaki]

when I send the waveform to the compact daq it shows the error 200077.  This is what it says

Post your VI so we can see what you are doing.

[ishironagasaki]

here it is

[RavensFan]

Check the channels you have assigned to each DAQ assistant.  It looks like both DAQ assistant4 and DaqAssistant are assigned to cDAQ2Mod1/ao1.

But in reality, you should not be using 4 different DAQ assistants to do analog ouputs on 4 different channels of the same device.  You would probably getting timing errors, and a message such as -50103 about a resource being reserved (the timing engine of the DAQ device.)

You should have one DAQ assistant that incorporates all 4 channels and merge your signals into a single wire that you feed to that DAQ assistant.

[ishironagasaki]

One of the problems turned out to be sample rate, but just in case that problem turns out how do you merge all the signals into one wire?

[RavensFan]

Merge signals is a part of the Express VI palette.

[ishironagasaki]

Once I merge the signals, how do I designate which channel each of the four signals goes to?

[ishironagasaki]

It turns out that the number of daqassistants isn't the problem.  I tried the vi with only one channel and the same error appeared.

The order of the signals in the merge function will match up 1:1 with the order the channels are defined in the DAQ assistant.

Maybe not yet.  You might be running up against the first problem and that is stopping the code from running before the second error has a chance to appear.

Can you attach one of your files? You are reading the file as integers. That does not look correct at all based on the image of the Excel files you posted.
