DAQ comunication problem

$

Hi,

 

I have made a application using LabVIEW that must read data from a DAQ (NI cDAQ-9184 and current module NI 9203) using tasks from NI MAX. I run the app at Windows starup, but sometimes when the app starts the comunication betwen DAQ and NI MAX is incomplete (The chassis is always turn on) and my app reads zeros when actually the module always receives a signal (4-20mA) from sensors. Then i must to open NI MAX and refresh the chassis or run some task and stop it to run my app again to obtain correct data. I need that app works without user interaction.

 

I hope you can help me... Regards.
