System Overview SIMATIC S7-1500

SIMATIC S7-1500 – the ultimate productivity and efficiency boost

Through its many innovations, the new SIMATIC S7-1500 controller sets new standards for maximized productivity. This benefits small-series machines as well as complex installations that place high demands on speed and deterministic. The SIMATIC S7-1500 is seamlessly integrated in the Totally Integrated Automation Portal (TIA Portal) for maximum engineering efficiency.

The SIMATIC S7-1500 is modularly structured, with scalable functionality.
Each controller consists of

  • A central processing unit (CPU) for executing the user program
  • One or more power supplies
  • Signal modules as inputs/outputs
  • And technology and communication modules as required.



The central processing units (CPUs) are the heart of the SIMATIC S7-1500. They execute the user program and network the controller with other automation components.

Three CPUs are available in the first delivery stage:

CPU-1511-1 PN for small to medium-sized applications

CPU-1513-1 PN for medium to large applications

CPU-1516-3 PN/DP for exceptionally demanding requirements and additional communication tasks.


Features and customer benefits
