Sampling of measurements takes place continuously with a frequency equal to that specified in the Period field of the group.

This type of sampling allows to record the trend of the specified measures 24 hours a day, thus generating a history of the production process.


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



Warning! If the recording on file of samples is enabled, pay attention to the size of the archive as sampling many measures with a high frequency it is possible to saturate the PC disk in a short time.
