Appropriate modules
The following table shows which modules may be used in the various slots:
Module type Permissible slots Number of modules
System power supply (PS) 0; 2 - 31 Max. 3
CPU 1 1
I/O modules 2 - 31 Max. 30
Point-to-point modules 2 - 31 Max. 30
Technology modules 2 - 31 Max. 30
PROFIBUS/PROFINET modules:
• When a CPU 1511-1 PN is used
2 - 31 Max. 4
• When a CPU 1513-1 PN is used
2 - 31 Max. 6
• When a CPU 1516-3 PN/DP is used
2 - 31 Max. 8
Special feature of the load current supply
In addition to the specified max. 32 modules, you need a load current supply to supply the
modules and the input/output circuits with 24 VDC.
The number of load power supplies is unlimited.
Load current supplies can be mounted on the "S7-1500 mounting rail" but do not have a
connection to the backplane bus.
Observe the installation rules and specified installation distances in the manuals of the load
current supplies.
