Compact and powerful: The SIMATIC S7-200 Micro PLC Siemens 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.
The Advanced Controller SIMATIC S7-1500 can be used in the entire automation industry in applications that are medium-sized to high-end machines with high demands on performance, communication, flexibility and technological features. 
Do you want to further utilize the investment into your machine or plant? The well-engineered, proven controller SIMATIC S7-300 will be available at least until 2020. Our 10 years spare part commitment starts thereafter. 
The most powerful Automation System within SIMATIC.
Superb communication capability and integrated interfaces make the SIMATIC
S7-400 process controller ideal for larger tasks such as the coordination of entire systems.
The graded range of CPUs enables scalable performance and the capacity for I/O
periphery is virtually unlimited.
What's more, process controller signal modules can be inserted and removed while the system is live (hot swapping), making it very easy to expand the system or replace modules.
