6 Time Settings
Example 1 The interval for retrieval is: every 2 hours during the operating period from
08:00:00 AM to 06:00:00 PM, with the setting “Immediate”. In this case, the
operating period can be divided by the time interval.
Example 2 The interval for retrieval is every 2 hours during the operating period from
08:30:00 AM to 05:30:00 PM, with the setting “Immediate”. In this case, the
operating period cannot be divided exactly by the time interval. So the retrieval
times for the following day will be shifted accordingly.
When data is retrieved for the 10th time, the start time will have come round to
09:05:32 again.
H
If the period is set to less than 60 seconds, the data are read out in
a continuous cycle, i.e. the connection to the device is never
broken. A continuous cycle is only stopped if an error occurs, on
cancellation by the user, or at the end of the operating period (if it
is active and the read-out has been carried out 100%). The
parameter for “Continue read-out beyond the operating period” in
the “Advanced (1)” tab also has an effect on the end of the
operating period.
H
If the option “Use period as absolute time” was active ( ), then the
behavior would not change, since both the operating period (10 h)
and a complete day (24 h) can be divided by the time interval (2 h).
