Snap the modules onto the rail, starting at the left and in the following order:
1. Power supply module
2. CPU
3. signal modules, function modules, communication modules, interface modules

If you install SM 331 analog input modules, please check EHIRUH installation
whether you have to reposition the measuring range submodules at the side of the
module. See Chapter 4 on analog modules in the 0RGXOH'DWD Reference Manual.
