Error-200279 occurred

[tritran]

Hi all,

I hope you are all have a great day.

I am measuring the turbidity of water by using Labview. I got the error code as in figure 3 (error code - 200279) and it suggested that increasing the buffer size, reading the data more frequently ....

Could you help me to solve this error? It's not happen every time I run the measurement, but sometimes I will get this error.

Attached are my block diagram and the front panel (Figure 1 and 2).

Really appreciate that you can help me with this.

Thanks!

Hi tritran,

Have you read this article on the issue?

Also, it is generally best to update your actual code, not a picture of the code. Especially when so much of your code is hidden behind express VIs and dynamic data, it is impossible to debug a .jpg. Preferably backsave to an older version like LV 2012 so more people can open it.

Hi gregoryj,

Thank you for the reply

I have read that article. I have changed the number of samples per channel, but still get the error sometimes.

I do not know how to increase the buffer size.

Attached is my code. 

Please give me some suggestions, that would be great.

Thanks!

Do you really intend to take Continuous Samples with a buffer size of 1 at 1 Hz?  This makes no sense to me.

I think you are being "intellectually crippled" by your use of the Dreaded DAQ Assistant and its Evil Twin, the Dynamic Data Wire.  Do a Web Search for the excellent NI White Paper whose title is something like "Learn 10 Functions in NI-DAQmx and Solve 80% of your Data Acquisition Tasks".  Then create appropriate Tasks in MAX or your Project, drop a Start, Read, and Stop VI, wire them appropriately, and see if that makes things work.
