If i download a new project for the CPU everything works fine, but after if I modify the hardware configuration (example change the address of ET200 IO inputs) and download again the CPU is not able to restart again an become frozen on STARTUP. Remove the CPU power do not solve the issue. If I download a completely different project for the CPU the PLC is able to RUN. And after that if I download again the original project the CPU is also able to RUN. Someone already experienced this issue?

Next, I share the link where you will find the most up -to -date versions of the PLC: "FIRMWARE UPDATE FOR CPU 1518F-4 PN/DP" Try to update it and see if you continue with the same behavior. If so, it would be good for us to eat the diagnostic buffer in .Txt to see if it can give us more imformation. Best regards!
