Distributed I/O



The SIMATIC ET 200 family makes distributed automation possible. The components of the system family are available in a host of different sizes and versions.

  • Modular I/O systems with low to high channel density

  • Maximum system performance on the basis of PROFINET

  • Safety and standard in one system

Benefits in the tunnel

  • Thanks to the distributed configuration, the signals can be acquired directly in the subdistribution boards in the tunnel, saving long cable runs

  • The distributed I/O system increases the availability of the overall system by means of redundant connection of the modules and the bus system
