Data logger

None: automatic recording disabled, can record by invoking the Sample method; Periodic: records the values of all the selected variables at regular intervals; Value change: at regular intervals records only the values of the selected variables that have changed with respect to the previous sampling.

Interval in hours, with millisecond precision, between one sampling and the next, in the Periodic mode.

Interval in hours, with millisecond precision, between one sampling and the next, in the Value change mode.

(Only for reading of variables from a controller) Enable/disable the storage of the operation code for the reading of the controller. If enabled, adds the relative column in the database for each variable.

Enable/disable the storage of the timestamp of each sample. If enabled, adds the relative column in the database for each variable.

Enable/disable the recording of the local date and time (Local time property of the events or session), in addition to the date and time in UTC+0.

(only for the Value change sampling mode) Method of calculating the change of values, with respect to the previous sampling, within which not to sample. Applies to all variables without specific dead-band mode. None: any change; Absolute: absolute change of the values of the variables; Percentage: percentage change of the values of the variables.

(only for the Value change sampling mode) Value of the dead-band interval. For example, if the value is 5, the logger samples the variables whose values have had an absolute or percentage change of at least ± 5 with respect to the previous sampling.

Database in which to store the sampled data.

Name of the database table in which to store the sampled data.

Collection of Variable objects to sample.
