DAQmx retriggerable problem on PCI-6110S

[hallwang]

Hi everyone,

I am trying to realize retriggerable analog data acquisition on PCI-6110, but meet with the error 50103 "The Specified Resource is Reserved". I would really appreciate if someone could tell me how to avoid this error in my case. 

Brief description of my code is below:

1. Use the freqout to generate a fast continuous pulse train as a clock signal.

2. Divide the frequency of this clock signal and generate a slower continuous pulse train, which is called LSYNC.

3. Use LSYNC as a trigger. At each falling edge of LSYNC, generate a finite pulse train, which is used as the sampling clock source for analog DAQ.

The code is attached. Thank you very much.

Dear hallwang

You will get this error when you are trying to access a resource that is already being used by another application. Make sure that you are not accessing any of your channels on another VI or a Test Panel.

Thank you, Efrain. I learn that the finite retriggerable pulse train uses two counters, which already reserves all the counters on the board. That's the reason I could not generate the other two pulse train. I decide to introduce another DAQ board to generate these pulse trains.
