Hi all,
I've recently been trying to make home-made profiler with a transducer and a laser.
The setup is pretty simple, the laser slides on a rail which is attached to the magnet of the transducer. The transducer gives me the position (x) of the laser and the laser gives me the distance to an irregular surface .
Combined together, if i take the distance given by the laser at every 1mm, I can create the profile of the irregular surface.
My issue is the PLC scan time which is about 20ms to 50ms. Since the scan time too long, the system has time to go through multiple positions before the scan is done which makes it impossible to get a distance value at every 1mm.
Does anyone have experienced something like this before?
I'm looking into buying a data logging card, but i don't know is this is my best option.
