If you opt for installation on a single rack, insert a dummy module to the right of the
CPU (order no.: 6ES7 370-0AA01-0AA0). This gives you the option of inserting a
second rack for your application in the future, simply by replacing the dummy
module with an interface module and without having to reinstall and rewire the first
rack.
