The counter seems doesn't work? (PCI-6014)

[AlexLing]

LabVIEW 6.1 PCI-6014, I want to count the digital signal.

I have connected one digital output (line 1) to the source of the counter 1 with one cable. First of all I have initialized the digital output with the value 0 for "iteration "(in „Write to Digital Line.vi”). I use the “Count Events or Time.vi” to do such a work and set "counter size (16/24-bits: 0)" which contains the 24-bits(DAQ-STC). I run this vi continuously, then I change the value to 1 for the "iteration" in vi "Write to Digital Line.vi". The counter doesn't count if I change the line state. Why?

Thanks,

Wei

Hi Wei,

please post your VI (incl. all your SubVIs) and the exact naming of the pins you have connected. This will make it a lot easier to fix this bug / find the problem.

Hi Daniel,

On Friday I have tried again and the problem is solved. The reason is that I have connected the source to another counter. I used a adapter box to realize the connection. There are counter 1 and counter 2 in the box. But in LabVIEW there are counter 0 and counter 1. that’s the point.

Thanks,

Wei
