After a reset the status of the safe monitoring functions is rebuild
If process values are beyond the parameterized trigger points, the status of the safe
monitoring functions is kept unchanged.
On time based functions, the timer value is reset and therefore the output status of the
relates function too. The function is triggered again if the time value versus monitored
status exceeds again the parameterized limits.
