Hello guys, I have a real problem designing a trigger for an application, what I'm doing is to power up a motor actuator and measure the current and voltage consumption during every actuation. What I would like to do is to start acquiring the signal once the voltage rises to a certain value and finish it when it falls to another certain value. The hardware that I'm using is a cDAQ 9178 with a NI9205 and 9221 modules. Any help / samples / detailed explanation on this matter will be truly appreciated. I have no idea on how to work with the triggering vi's in Labview. Regards SergeArmz

Finally after a lot of research, trials and many developments, here it is a VI that I developed that is capable to do what I was looking for. Thanks to the guys that helped me out in to figure how to solve my issue. I'm attaching the VI for all of those that may have the same problem that I had. And of course if you can improve what I did will be great, I think this is the the goal for this forum Cheers! SergeArmz
