Example
The MSS 3RK3 Advanced monitors a non-safety-related AS-i slave. A release and an indicator
light are connected to this AS-i slave. The data tra󹪟c between the AS‑i master and the non-
safety-related AS-i slave can be fed into the logic of the MSS 3RK3 Advanced and processed. An
additional indicator light is connected via an expansion module.
