Helo, my question is if the newest logo 8.3 supports profinet or only MODBUS TCP/IP connection and S7 connection with Simatic ?

Thanks for your answer :)

To read I/O, a mask must be created between I/O and memories.

because of the translation there is doubt: Was that meant as a statement or a question? What do you mean by "mask"? People reading your post may be just as confused as I am. Consider making an image of what you mean.
