Example 3 for time based function (time monitored antivalent inputs) => Reset of the alarm,
return of alarm status if time versus input status exceeds again the limits.
Safety note:
On time based functions, i.e. time based monitoring of complementary input signals, the
reset-function cause a reset of a possible alarm status. Only if the time versus input status
exceeds again the parameterized limits, the alarm status is recalled.
For safeguarding of false utilization of the reset-function, i.e. reiterated call of the reset-
function to bypass the alarm status, adequate measures in the application program (PLC-
program) have to be implemented.
