I have an NI-9401 installed in a cDAQ-9174 that I'm using to count input pulses. I would like to be able to cascade the counters to have implement a 64-bit counter, but I'm having difficulties figuring out how to accomplish this.
After digging around through manuals and help files, I've been able to create the following (VI is attached):
To cascade the counters, I suppose I must route Ctr0InternalOutput to the input of the second counter, but I can't find how.
Any suggestions? Perhaps I'm simply looking in the wrong place. I've been using the 9174 manual and the DAQmx help file. None of the examples that I've looked at deal with cascading counters, and while the subject is mentioned in the manual, the only other talk about paired counters have to do with frequency/period measurements.
Solved! Go to Solution.

I finally figured this out - by right-clicking on the constant/control I create that's connected to the CI.CountEdged.Term property, selecting IO Name Filtering, and checking the Include Advanced Terminals button then allows me to select /cDAQ1/Ctr0InternalOutput as the input to ctr1.
