The basic system of the CPU 410-5H for stand-alone operation
Definition
Stand-alone operation refers to the use of a CPU 410-5H Process Automation in a standard
SIMATIC-400 station.
Hardware of the basic system
The basic system consists of the hardware components required for a controller. The
following figure shows the components in the configuration.
The basic system can be expanded with standard modules of the S7-400. There are
restrictions for the function modules and communication processors. See Appendix Function
and communication modules that can be used in a redundant configuration (Page 335).

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).
Note
The rack number must be set to "0" on the CPU.
