I would like to synchronize AI, AO and DO finite tasks that are retriggerable based on a CO pulse train. I have set up a CO Pulse Freq task to run off ctr3 of my 9178 chassis. The rising edge triggers the AO to start, the falling edge triggers the AI and DO to start. Provided these finite tasks are short enough they should be retriggerable, thus each time my CO sends a pulse they should restart.
Having trouble making this work, get an error that the AI task is not retriggerable (using 9222). Can anyone provide guidelines on how to set such a scheme up?
Gracias.
