When I start LavVIEW program using DAQmx Read 4, I have an alert message with error 200284 (See the attached file).
How can I fix it?
Error -200284 occurred at DAQmx Read (Counter ID U32 1Chan NSamp).vi:1
Measurements: Some or all of the samples requested have not yet been acquired.
To wait for the samples to become available use a longer read timeout or read later in your program. To make the samples available sooner, increase the sample rate. If your task uses a start trigger, make sire that your start trigger is configured correctly, It is also possible that you configured the task for external timing, and no clock was supplied. If this Is the case, supply an external clock.
How to fix error -200284 in DAQmx?
The error 200284 occurred on DAQmx Read if the timeout occurred before any of the samples made were received. To have this resolve, you may try any of the following:
Adjust the timeout value input for the DAQmx Read which specifies the amount of time in seconds to wait for the availability of the samples.
Read later in your program if it is controlling the equipment that is generating the signal to read the delay before the samples become available.
Make sure that the start trigger is configured correctly.
Check and verify that the external timing is configured right.
