Interval: Number of hours after which the maintenance must be performed. When this time expires, the
warning or alarm bit belonging to the task is set for the last time.
Time of the first
warning: Number of hours after which the first warning is output. This time must be greater
than or equal to the interval.
Number of warnings to be output: Number of n warnings to be output before the alarm. The alarm bit is
therefore set maximum (n+1)-times, i.e n-times as warning and 1-time as alarm.
Reserved: Reserved for expansions.
Example:
Interval = 100
Time of the 1st warning = 80
Number of warnings to be output = 2
After the task is started, the warning/alarm bit is output for the first time after 80 hours, a second
time after a further 10 hours (i.e. after a total of 90 hours), and the warning/alarm bit is set for
the last time after 100 hours.
