PROFIsafe watchdog, PROFIsafe communication
error or undervoltage/overvoltage was identified.
Note: In this transition, it is possible that
WD_timeout bit of PROFIsafe F-Host instance
toggles if watchdog timeout is periodically recog-
nized by the Safety I/O module.

If the threshold shut-down value was not reached
during process undervoltage or overvoltage
phase and the process voltage is back in the
normal range, the Safety I/O module reintegrates
and would go to RUN (ok) state automatically, but
short time before the “activate_FV_C = 1” com-
mand was sent from the PROFIsafe F-Host
stack, which leads the Safety I/O module to RUN
(module passivation with a command) state.
