Ultrasonic Sensor daqmx

[Zzimmha42]

Hey people,

I am currently working on a project to test ultrasonic sensors (Pepperl+Fuchs UB4000-30GM-H3-4Dt04) using the continous measurement and logging message handler labview template. I am using an NI 9425 digital input and an NI 9475 digital output module. In my attached program I am able to display the digital signal as well as show the initial trigger that sends the pulse from the sensor out. Unfortunately I cant figure out how to display the echo pulse (response) of the sensor. Another relevant issue is that whenever the sensor triggers a pulse, the digital signal goes to 0 and stays there even after the VI is closed. The only way ive been able to get the digital signal back to a 1 is to disconnect and reconnect the input module. any help, feedback, or suggestions would be greatly appreciated. thank you!

Hey,

actually I am also working on a project with an ultrasonic sensor from Pepperl+Fuchs.

I would like to measure the time my ultrasonic impulse needs to travel to the nearest object.

I have some problems in triggering the signal and getting a precise time value and I would

really appreciate any help. Maybe you where able to fix that problem last summer ?

Thanks in advance for any help!

I am using Labview 11.0. It would be so cool, if you would post your VI's for that version.

Best greetings,

Felix
