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.

 

General

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

Thanks to numerous innovations, the CPUs of the SIMATIC S7-1500 deliver the ultimate plus in productivity and efficiency. The hardware is extremely compact. Highly integrated, highly versatile components and modules save space in the cabinet and reduce the spare parts inventory overhead.
