Hardware configuration

Introduction
The S7-1500 automation system/ET 200MP distributed I/O system consists of a single-row
configuration in which all modules are installed on one mounting rail. The modules are
connected by means of U connectors, and thus form a self-assembling backplane bus.
You can configure the S7-1500 automation system/ET 200MP distributed I/O system with
fail-safe and non-fail-safe modules.

Hardware configuration of the S7-1500 automation system

M aximum configuration
● The integrated system power supply of the CPU supplies 10 W or 12 W (depending on
CPU type) to the backplane bus. The power budget calculation determines the exact
number of modules (without optional PS) that can be operated with the CPU. The
operating principle is described in section Power balance calculation (Page 45).
● A maximum of three system power supplies (PS) is possible: one can be inserted to the
left of the CPU and two can be inserted to the right of the CPU.
● If you insert a system power supply (PS) to the left of the CPU, this yields a possible
maximum configuration of a total of 32 modules, which occupy slots 0 to 31. If system
power supplies (PS) are needed to the right of the CPU, they each occupy one slot.
