Basic Controllers

Basic Controllers – be flexible thanks to networking possibilities

Basic Controllers are the intelligent choice for compact automation solutions with integrated communication and technology functions. They are available in both standard and safety versions.

Advanced Controllers

Advanced Controllers – increase productivity with the ultimate power

Advanced Controllers automate not just complete production plants but also applications that demand the greatest performance, flexibility, and networking capability. SIMATIC S7-1500 is the latest controller generation and therefore the most future-proof controller with optimal system performance.

Distributed Controllers

Distributed Controllers – save space with the smallest footprint

Distributed Controllers are used for machines with a distributed architecture and for series machines with limited space available. They combine the advantages of a SIMATIC S7-1500 with the design of a SIMATIC ET 200SP. With SIMATIC ET 200pro, a CPU module with S7-1500 technology is available as a modular space-saving solution for tough environmental conditions near the machine. 

Software Controllers

Software Controllers – be open and independent

The Software Controllers are used wherever maximum precision and speed are required as well as PC-based automation. The PC-based controllers operate independently of the operating system.

Happy birthday, SIMATIC!

System overview

SIMATIC Controllers by comparision

Every machine or plant is different in terms of system performance needs and complexity. With its comprehensive range of SIMATIC Controllers, Siemens offers the perfect control solution for every application. 

The SIMATIC S7-1200 Basic Controller for small to medium-sized applications, the SIMATIC S7-1500 Advanced Controller for medium-sized and complex applications, the SIMATIC ET 200 Distributed Controller for distributed applications, and the SIMATIC S7-1500 Software Controller for PC-based applications. For the implementation of failsafe applications, all controllers are also available as failsafe versions.

SIMATIC Controller portfolio

Integrated functions in all SIMATIC Controllers

In addition to their scalability, every controller offers integrated system functions such as efficient engineering, high performance, innovative design, reliable diagnostics, Safety Integrated, Technology Integrated, and Security Integrated. This allows great flexibility in the design or adaption of automation solutions, without having to constantly accumulate more knowledge and expertise.
