I'm acquiring analog data and using DAQmx Trigger Property Node to pause the data input when one channel is below a certain value. I've set the Trigger's type as "Analog Level" by creating a constant on the block diagram. When I run the program, I get error #200557, "Specified property cannot be set while the task is running." I guess my questions are 1. If the type is set as a constant, why should the trigger try to set it while the task is running, and 2. How can I set this before the task begins as the DAQmx Trigger takes a task as an input.
