Expansion of Basic System with External
1/0s
You can expand the programmable controllers by using S5-1OOU external
1/0
modules. If you install
S5-1 OOU external
1/0
modules, mount the controller, bus units, and interface module on a 35-mm
standard mounting rail and connect them to each other via the ribbon cables of the bus units. Each
bus unit has room available for two
1/0
modules.
Figure 5-1 shows a basic unit expanded with external
1/0s.
