error 200279 occured when use DAQ Assistant

[AmeHyesung]

Hello everyone!!!

We are using labview for our major project, but now we are facing some problems. 

We use NI 9229 to get voltage value from two batteries and NI 9227 for current.

When set our DAQ assistant to 'continuous Samples 10 samples to read 100Hz', our vi will shut down after about 7 or 8 sec and shows error 200279.I try to increase the frequency and fix number of samples to read but both are useless. I found from NI support that I could increase buffer size but what I use is DAQ assistant nut DAQmx, I dont know how to increase buffer size.

 But when I change to 'N samples' it won't shut down' while it requires a high frequency. We want to set to 1Hz for our data reading, but it shows error like pic below.

After set our DAQ assistant to 'N samples, 10samples to read, 100Hz', the data lookes like the pic below. I totally have 4 channels but 2 channel read data normally while other two don't. Also the time colunm is also has some error. It shows a strange value from A12. But when I test this program with NI 9205 it works very good...

also for our front panel... two of our current signals only display one, the other one always show 0.00

I don't know why while it work well when I run the circuit 2 indepently.

Here I have attached our vi.

Could anyone helps us with these problems ??

Thank you so much!!!!
