Change Detection in Analog Output Task

[NilsN]

Hi,
I use a PCI6014 board with a BNC2120 adapter and LabView 8.2. My goal is to write data at every rising edge of a reference signal. I receive this TTL reference signal at analog input AI0 and write data in an analog output task to AO0.
Is it possible at all to use the "change detection" timing VI in an Analog Output Task ("rising edge physical channel" terminal wired to AI0)? I get the error code -200077 directly after the "change detection" VI! (I could not find any reference to that code!)

Thanx for your help!
Nils

Hi Nils,

unfortunately your attached VI is corrupted so that I´m not able to open it. But I think that I can help you anyway.
Error 200077 means that the operation you are trying to perform or the values you selected are not supported on the device you are using.
This means that the function you would like to use is not available with you  HW.
But this should be no problem because you can also realize this with a reconfigureable trigger. Have a look at the example Acq&Graph Voltage-Int Clk-HW Trig Restarts.vi to see how to use it. You can find the example with the example finder in LV and search for "Trigger". This example show how to acquire data but it is no problem to change it to write data.
Hope that will help you.

Regards, Chris
