Hi schapie, I am using a AC/DC24V LOGO!24RC. The sensor is a burkert flow sensor 8030. The program i upploaded is a testprogram as i wanted to bench test the circuit before i uploaded to the main program. You mentioned that you used an optocoupler...did you use the same power supply unit to feedthe isolated side of the optocoupler into the input on the logo? If so, did you notice any difference in the peak to peak voltage? I am starting to question whether i have a faulty logo as i really cannot see why it is not working. The input voltage stays the same, the only thing that seems to change is the frequency. It would be good to see your solution. Attachmentwater system pressure.zip (493 Downloads) |

Hi Sean, your LOGO!-type has NO fast frequency inputs - the maximum frequency is 5 Hz !!! Use a other LOGO!-basic module.... OR look under my answer at Water Flow sensor - Counting Pulses HELP! Best regards Betel |
