Integration of the MSS 3RK3 Advanced into a higher-level, fail-safe control
The MSS 3RK3 Advanced monitors the various safety-related and non-safety-related AS-i slaves
as a safety monitor and exchanges up to 12 safety-related signals bidirectionally with an
AS‑i safety monitor.
Moreover, the MSS 3RK3 Advanced can mutually independently control up to 12 safety-related
AS-i outputs (with up to 4 outputs).
Up to 12 safety-related signals can be transmitted by the MSS 3RK3 Advanced to an F‑PLC over
the F‑Link.
