Sorry i mean on rail and what must change in program when i change from cpu314 to cpu315

only hw config

hi,

see following manual chapter 5 

SIMATIC S7-300 CPU 31xC and CPU 31x: Installation

This will be very helpfull for you, there are pictures where you see how they connected to the rail and each other. 

To change it in your project go to the HW-config and try with rigth-click on CPU, then click replace Object. 

you can also try to delete the CPU and try to Insert a new Object. But don´t delete your programm by deleting the old CPU.

Don´t forget to make a Back-Up before start changing

hope this helps,

regards,
