DB9904 Actual data table [r16]
DBW252 Reserved_1 32
DBW254 Reserved_2 32
Remaining time: Number of hours remaining after the start of the task until it expires.
Remaining time ≠ 0 and associated alarm bit set: Warning
Remaining time = 0 and associated alarm bit set: Alarm
Number of warnings output: Number n of warnings that have already been output. If the interval has
expired completely, the output value is (n+1):
n = "number of warnings to be output"
1 = alarm at the end of the interval
Reserved_1, ~_2:
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 remaining time is decremented every hour.
● After 80 hours, the remaining time is 20 hours and the number of warnings that have been
output is increased from 0 to 1.
● After a further 10 hours (i.e. a total of 90 hours), the remaining time is 10 hours and the
number of warnings that have been output is increased from 1 to 2.
● After 100 hours, the remaining time is 0 and the number of warnings that have been output
is 3 (= 2 warnings plus 1 alarm).

Acknowledgment n: The acknowledgment bit assigned to task n:
Under the precondition that the corresponding acknowledgment blocking bit is not set, the setting of the acknowledgment bit
restarts the task and, in particular, the actual data of the task is set:
Remaining time = interval
Number of warnings output = 0
The bit is automatically reset at the end of the PLC cycle.
Example:
Interval = 100, time of the 1st warning = 80, number of warnings to be output = 2
