This case considers the signal 󹪞ow from a safety-related AS-i sensor (AS-i EMERGENCY STOP) to
a safety-related AS-i output. The EMERGENCY STOP transmits an OFF signal to the
MSS 3RK3 Advanced. The MSS 3RK3 monitors this safety-related AS-i input slave. After taking
input delay times and timer functions in the logic into account, the MSS 3RK3 Advanced
transmits a signal to the safety-related AS-i output that shuts down the system. In this way, MSS
3RK3 controls a safety-related AS-i output.
