Hello Valerio,
After you rebuild the project in SafeDESIGNER, the step you are missing is to build and transfer the project via Automation Studio. The mapp Safety HMI does not have access to the SafeDESIGNER project on your PC, so you need to transfer that project to the gray PLC so it can be loaded with the mapp Safety HMI. You can track the project CRC through your screenshots and see that you are recommisssioning CRC ‘CD230DA1’ through the mapp Safety HMI, while the SafeDESIGNER project has CRC ‘22A1A7C9.’
Below is a rough diagram of the difference between a SafeDESIGNER download and a mapp Safety HMI transfer.
