Hello Simotion,Please check How do you connect a panel to a SIMATIC H station?. Make sure you do not connect CPU's Profibus master interfaces together if they have distributed I/Os.
You should always take a backup before you modify anything. Make it always your first step. You can upload your configuration here to be checked if you like. NO.
You should check the S7-400H manual carefully.All your questions are answered in chapter 14 (System modifications during operation). Just one hint, if you have flash memory cards then you must make sure that you download your program to the memory card not the CPU memory. Best regards. H-H |

Hello Simotion, your procedure looksok but I recommend to stop your CPUs first before any other step. Just note that when you switch on power supplies,bothCPUs will take about 10 mins for self test. In these 10 mins you will not be able to download anything. Best regards. H-H |
