Transitions between FSO modes and states
The following diagram shows the possible transitions during normal operation of the
FSO module.
• Power down:
STO active, power off (below 19 V)
• Start-up:
STO active, power on (above 19 V), start-up checks performed
• Configuration: STO active, setting of parameters
• Operational:
STO inactive, FSO running
• Operational:
STO active, POUS active, FSO running
• Safe:
STO active, FSO running
• Fail-safe:
STO active, I/O, FSO or communication fault detected.
FSE module or encoder failure situation can also cause the Fail-
safe transition. See parameter
