Hello experts,

I want to use s7-1200 cpu(1214C) with S7-300 I/O modules via IM153-1 profibus module.

I configured hardware(see attached picture). Problem is, I can not give I/O adress s7-300 modules. Adress sections grayed out. The adresses used plc software. I migrated project s7-300 cpu. 

I m using tia portal v16.

How can I give I/O adress s7-300 modules.

Thank you.
