SIMATIC ET 200S - the complete product portfolio for distributed automation systems

Multifunctional and reliable SIMATIC ET 200S

The SIMATIC ET 200S is a complete product range specifically designed for distributed automation systems. Thanks to its robust, shock-resistant design, it is ideal for a wide variety of industrial environments.

PROFINET interface and I/O modules

ET 200S offers a variety of communication interfaces, which are connected via PROFIBUS and/or PROFINET. CPU-equipped interface modules allow operations to be performed directly at the I/O devices, significantly speeding up the response to time-critical signals.

Stand-alone stations or distributed automation system

Interface modules with CPU functionality can operate both as stand-alone stations and as part of a distributed automation system with local intelligence. This makes it possible to implement medium-sized programmes. The performance of these modules corresponds to the CPU 314, enabling distributed process data management even in the case of fail-safe versions.

Solutions for different applications

The ET 200S offers a wide range of products for a variety of tasks in industrial automation:

  • Technology modules
  • Engine starters
  • Frequency converters
  • Pneumatic interfaces
  • IO-link sensor modules
  • Fail-Safe modules (input/output and voltage module)
  • Profibus network master modules
