USB6259 Trigger with static digital

[mq17]

Hi,

I have a VI that controls a linear motor control with digital lines. At one point in the program setting one of these lines triggers an analog input task and a counter pulse task. This is done by putting a wire between the digital line and e.g.. PFI0 using this as the trigger input. This works OK.

My general question: Is there any solution, where I can use an internal signal of the 6259 avoiding the wire connection?

hi mq17,

I did not find a clear information saying that this is possible (nor impossible). What you should try is to create an internal route between the digital line and PFI0 using the DAQmx Connect Terminal VI. I can not guarantee you it will work but this is worth trying:

DAQmx Connect Terminals (VI)

Don't forget to disconnect the terminals at the end of your programm

Best regards

Hi Florian,

thank you for the hint. I looked at that before but could not find my digital line in the offered connection sources. Now I tried the corresponding PFI denominator for the line (Port2/Line0 = PFI8) and it works!

Thank you
