Terminal designation in Safety ES
Terminal designation BMK.OUT Explanation
SLOT3_ASI#xx-F-Qc Sensor signal from MSS 3RK3 to AS‑i master that can be
evaluated by an AS-i output.
xx: AS-i address
c: Number of the output (1 ... 4)
Example
The MSS 3RK3 monitors the safety-related AS‑i input slave "EMERGENCY STOP" and sets and
resets the safety-related AS‑i output, which switches the motor o󹪜.
