NI 9411 with Siemens Sitrans F M Mag 6000

[JonasM]

I have a Siemens SITRANS F M MAG 6000 that I connect to a 9411 and ctrl 0 to measure make a frequency measurement.

When I connect these two devices together I don't get any frequency at all. Is there anyone that have used the Siemens SITRANS F M MAG 6000 to measure flow of fluids and being able to measure the frequency.

I've connected the hardware according to attached pictures. I know that PFI1 is used by default but I've rerouted that and I tested it with another device and seen that I can count the frequency with this task also attached.

DUT+ is connected to pin 56 in the manual also attached

DUT- is connected to PFI0 and GND by a 2k2 ohm resistance. I've also tried without the 2k2 and that didn't help either.

Any help appreciated.

Connection was not the problem. After going through all settings of flow meter it started to send out pulses as expected.
