Siemens SIRIUS 3RK3 - Communication of MSS 3 RK3 with AS-I Interface

6.5.2 Communication of MSS 3RK3 with AS-i interface
Requirements
The MSS 3RK3 is an AS‑i safety monitor and/or an AS-i slave on the AS‑i bus. You therefore
additionally need an AS‑i master and an AS‑i power section on the AS‑i bus to operate the AS‑i
network. MSS 3RK3 also supports conventional AS-i components as well as AS-i Power24V
components.
Before the MSS 3RK3 can participate in AS-i communication, it must be informed by means of
con󹪝guration in the Safety ES as to which AS-i slaves on the AS-i line are relevant for MSS 3RK3
and which AS-i slaves the MSS 3RK3 is to represent/simulate.
Communication
Unlike MSS 3RK3 Basic, the 3RK3 central units with AS‑i interface can be connected to an AS‑i
bus. Otherwise, the same interfaces are available as on the MSS 3RK3 Basic.
