Same I/O addresses in modules

Hello Nikodem;

You give us too little information for us to help you.

What modules are you changing in the CPU rack to introduce Profinet instead of Interbus? How about the IO devices in the field?

Are you attempting to change the communication interfaces without adapting the I/O addresses or the programming?

Please provide us with a detailed description of your project, including hardware and configuration you are planning to change. Screenshots could be helpful.

Hope this helps ,
