Counter with 6601 DAQ

[silvio]

I Cannot use counter 3 and 4 of a DAQ 6601 board in Visual Basic.
Someone know as configuring it in Visual Basic with ComponentWork ?

I Have to receive signal from four one-channel encoder but only two counter
work.

PFI 39 -> Counter 0 (work)
PFI 35 -> Counter 1 (work)
PFI 31 -> Counter 3 (don't work)
PFI 27 -> Counter 4 (don't work)

I think that problem is in the configuration of PFI31 and PFI27.

Sorry for language
regards

If you're using the same code and properties for all the counter operations, there should be no problem. You might double-check your wiring.

Also test the counters in Measurement and Automation Explorer to make sure they are working properly.
