Sampling of measurements takes place only for the intervals specified in the Time group, with a frequency equal to that specified in the Group Period field.
This type of sampling is indicated when the monitored plant is operating only at certain times (as it limits the number of samples recorded on file to only useful samples) or for the creation of historical archives for work shifts.
The entry, modification and deletion of the sampling time intervals are managed by the commands placed under the list in the Timetable group.




The window for configuring the sampling intervals is shown below:




Warning! The system does not perform checks on the overlapping of the start / end time of the configured intervals: it is up to the operator to configure correctly according to his needs.


Note: for this type of activation, the system performs a "forced" sampling when the sampler is restarted.
