Hi alijuda, you could have gotten this information from the manual please read before asking simple configuration questions. To answer your question yes, you will usually have one s7 program that will need to be downloaded to both master and slave.
Many Thanks fredz0003 , My point as below and attached pic.
Master CPU have "S7-Program & Connections" under their tree
Slave CPU have only "Connections " under their tree
Is that normal for Redundant works

Yes it is normal. However @rjua mentioned when you transfer it loads on both CPU's. In my experience when I've downloaded projects to both CPU's you have to download one at a time.
I could be wrong maybe other projects are setup different, but that's just my experience.
