Error message when using counter indicating need to use faster timebase

[pwduncan]

I'm attempting to use the two onboard counter timers on my DaqPad 6015 with a SC2345 carrier.

The program initially runs as expected, but once in a while I get an error message that reads as follows:

"2 consecutive active edges of the input signal occured without a counter timebase edge."

"Use a faster counter timebase"

I have only attempted to read this signal at two known frequencies: 15 and 20 Hz.

Can anyone advise as how to correct this or how to change the counter timebase?

I'm using the built in Express Daq Assistant to create the code to read the frequency so that part is pretty straight forward.

This command is however inside of a case structure, so each time it reads it is possible to reset or miss the first leading edge of the signal.

Thanks,

Patrick

Hi Patrick,

It sounds like the program is lagging when you attempt to read the gate of this counter. 15 Hz seems slow in comparison to the specs of the counter, but if your VI is slow by 7/100th of a second the program will thrown an error. I recommend probing the counters to determine where in the program the error occurs.
