9.2.5 S7-300 rack
The S7-300 rack can have up to 11 slots numbered 1-11. Slots 1-3 can contain only a spe-
cific module: slot 1 can contain a power supply module (PS), slot 2 a CPU module (CPU),
and slot 3 an interface module (IM). Thus, if no PS or IM module is used, the corresponding
slot must be left empty.
Slot 4 and later slots, however, may contain any of the SM module (digital or analog I/O),
communication module (CP), and function module (FM). Slot 4 and later slots must not be
left empty. A supplementary rack must have slots 1 and 2 left empty. It is recommended
that the FM or CP module be inserted in the main rack, as it cannot always be inserted in a
supplementary rack.
9.2.6 Adding the power supply module
Insert the power supply module first in slot 1.
When adding the power supply module, CPU module, or I/O module to the rack, you can
use one of the two methods: slot specification and drag-and-drop.
 Slot specification method
Select a target slot and double-click on the module as follows:
1. Click on a slot of the rack to which you want to add a module of your choice. The
selected slot is indicated by blue background.
2. Click on the module in the hardware catalog. The selected module is indicated by blue
background.
3. Double-click on the same module. The module is automatically inserted in the selected
slot.
