Hi all,

I have an S7-1515TF and 3x F-DI + 1x F-DO. I have assigned the F address to all modules, and now I want to change the address. For example, I previously assigned 65530 to the first module, and it was fine, but now I need to change it to another address.

1. I change the address in the F-destination address field of the module properties menu.
2. I compile it and then download it to the CPU.
3. Now I should be able to change it from the "Assign PROFIsafe address" menu of the CPU. However, when I select the modules and press the Identification button, I get a warning that says the actual address and configured address are different, and the confirm checkbox is inactive!

What is overlooked?
