Hello every body,

I have tested my input directly (with a +24v wire), and its ok.
By design, DIO input have resistance pull up ? The device output is PNP.
What can i do to make this work ? Am i doing it wrong ?

I will add some details:
The problem is that I do not receive the pulses from the energy meter. I am suppose to receive 1 pulse every 100w/h :(.

Hi c.jg, this sounds like you need to use a counter on rising edge with the pull-ups deacitvated.
Have a look at the "OutputPushPull" setting.
It specifies whether the outputs are operated in push-pull or highside mode.
The counter configuration is explained in the video Tutorial 14 – Counter and Encoder
