Dynamically Selecting Trigger Bus Lines

Last Modified: January 31, 2020

Management of trigger lines is another feature of NI-DAQmx routing. If you hard-code two measurement tasks to the same trigger line for different signals, at least one of the measurement tasks causes a resource conflict. Multi-device routing allows you to dynamically select trigger lines at run time. This means that NI-DAQmx selects any available trigger line. You can still select a specific trigger bus line by splitting your multi-device route into two single-device routes. However, the two static routes lose the ability to dynamically choose an available trigger at run time.
