AS-i safety solution with F-CPU and AS-I in ET 200SP

AS‑Interface configuration with AS‑i master modules in the ET 200SP

The AS‑i communications modules in the ET 200SP facilitate the use of AS‑Interface under fail-safe SIMATIC or SINUMERIK controllers.

The allocation of tasks is as follows:

• Acquisition of safety-related signals via safe input slaves on the AS-Interface bus.
  Further signals can be detected through other F‑DI modules of the SIMATIC.
• Evaluation and processing of signals via the fail-safe SIMATIC or SINUMERIK control
• Reaction via F‑DQ modules of the SIMATIC

Simple combination of the CM AS‑i Master ST and F‑CM AS‑i Safety ST modules in one ET 200SP station results in a powerful, safety-oriented gateway between PROFINET (or PROFIBUS) and AS‑Interface, which can be expanded further in a modular fashion with further I/O modules of the ET 200SP.

Using these design methods, it is possible to create configurations for virtually any application. Besides the single AS-i master, double, triple or generally multiple masters can be realized with or without Failsafe functionality.
