BEST REGARDS

 what HW/SW you put inside? This is important to know because all can depend to some communication options/connections created and defined IP/subnet options inside CP cfg. Prior make some prj, pls do simple test with CPU and CP configured with minimal options. CPU only with OB1 (clear is enough) and CP configured with correct MPI and IP address. After download (also here in my case) all is working without problems, also after power off. Pls explain via which interface you want connect to PLC and what you've set on PG/PC interface.
