3 SIMATIC S7-300/S7-400 and SIMATIC S7-1500 System Architecture
The CPU executes the user program and the integrated system power supply
supplies the electronics of the modules used via the backplane bus.
The I/O modules form the interface between the controller and the process.
Figure 3-2 shows a sample configuration of an S7-1500 automation system.

Memory concept
As the program memory, the S7-1500 automation system uses a SIMATIC Memory
Card. The SIMATIC Memory Card is a preformatted memory card that is
compatible with the Windows file system. The memory card is available in various
sizes and can be used for the following purposes:
Portable storage medium
Program card (external load memory for the CPU)
Firmware update card
Service data card
For writing on/reading from the SIMATIC memory card, a standard SD card reader
installed in the SIMATIC field PG and most PCs is sufficient.
The SIMATIC Memory Card is mandatory for operating the CPU.
Note The SIMATIC S7-1500 system manual provides information on the S7-1500
automation system.
