Device is in Sleep Mode. All
outputs are OFF.
Device is currently in Normal
Mode. Watchdog is active if
enabled.
Device is currently in Fail-safe
mode due to watchdog timeout

output states depend on the
corresponding input in case
the FSI is open.
Device is currently in Fault
Mode. The faulted output(s) is
(are) OFF. The safe autoretry
circuitry is active to turn-on
again the output(s).
