Duris_IHi, Bysulo24 You can now read the value without any problems, what are you asking? Can you try a Uint value instead of Real? instead of 41003 valueyes, all what is Hello everybody,I am trying to connect my S7-1200 to a MOP301 sensor (see .pdf attached). I think that the problem is related to the address, but I am not able to find what I am Now I have a problem connecting both of them at the same time.
