hI, As per my knowledge, you have to download HW config to both CPUs at least for the first time. Because afterward, normally you change only the user program. And it can be downloaded only to the master CPU. When you download the HW config, a pop-up message will ask you: To which H-CPU do you want to download? And you have to select one of the 2 CPUs. And whenever you perform a restart to the system one CPU is master, and the slave CPU updates the user program from the master. You can look at the below figure for a better understanding. More info can be found in SIMATIC FAULT TOLLERENT SYSTEMS S7-400H
