S7-200
SIMATIC S7-200: Micro PLC for basic automation tasks
Compact and powerful: The SIMATIC S7-200 Micro PLC is fast, communication-capable and highly productive in real-time mode.
The consistently modular design facilitates the creation of tailor-made, expandable solutions in the low-end performance range.
The S7-200 Micro PLC from Siemens can be used as either a stand-alone Micro PLC solution or in conjunction with other controllers.
S7-300
The S7-300 is the best selling SIMATIC controller which makes successful automation solutions possible. The SIMATIC S7-300 enables integrated and low-cost system solutions in centralized and distributed configurations.
Application
Automotive industry
Machine building
Plastics processing
Packaging industry
Food and beverages industry
Installation
The S7-300 enables a space-saving modular configuration to machine controllers adapted to the task at hand, without taking slot rules into consideration. A fan is not necessary during operation. Apart from the modules, only a DIN rail is required where the modules are swung into place and secured by screws. A configuration is then possible which is robust and electro-magnetically compatible.
The S7-300 CPU spectrum covers following CPU variant
Standard CPUs
Failsafe CPUs
Compact CPUs
Technology CPU
S7-400
The S7-400 is the most powerful PLC in the SIMATIC Controller family; the range that enables successful automation solutions with Totally Integrated Automation. The S7-400 is an automation platform for system solutions in the manufacturing and process industries, and is distinguished above all by its modularity and performance reserves.

Steel industry
Power generation and distribution and more
The S7-300 CPU spectrum covers following CPU variant:
CPU412-1412-2414-2414-3
CPU 416-2416-3417-4
CPU 414-H417-H Failsafe CPU
Installation
An S7-400 system consists basically of a backplane, a power supply, and a CPU. The system is modular and can be set up easily without the need to observe slot rules. The S7-400 is characterized by rugged fan-free operation with hot swapping of signal modules.
A diverse range of modules can be used both for centralized expansions and for easy setup of distributed structures with the ET 200; this results in extremely low-cost spare parts inventory.
