The CPU 410 basic system for stand-alone operation

Definition
Stand-alone operation refers to the use of a CPU 410 in a standard SIMATIC-400 station.
Note
Rack number "0" must be set on the CPU.
Hardware of the basic system
The basic system consists of the required hardware components of a controller. The
following figure shows the components in the configuration.
You can expand the basic system with standard S7-400 modules. There are limitations in the
case of function and communication modules. See Appendix Function and communication
modules that can be used in a redundant configuration (Page 389).
Figure 2-3
Central controller and expansion units
The rack containing the CPU is called the central controller (CC). The racks in the system
that are equipped with modules and connected to the CC are the expansion units (EU).
Power supply
For the power supply you need a power supply module from the standard S7-400 system
spectrum.
To increase availability of the power supply, you can also use two redundant power supplies.
In this case, you use the power supply modules PS 405 R / PS 407 R.
A combination of these can also be used in redundant configurations (PS 405 R with PS 407
R).
