The Interpolation feature
Check out a set of examples providing an overview of the i4connected Signals Interpolation feature.
The Interpolation feature calculates the missing data points in a gap by obtaining the difference between the last data point before the gap and the first data point after the gap and dividing it by the number of missing 15-minute periods.
The Signal Interpolation can be activated in the Add / Edit Signal panel.
The Signal Interpolation setting
Let's take as a first example the image below:
Example 1 - Interpolation
The dashed line represents the detected gap. Like in the first example, the gap is detected between 0:15 and 1:45. The alarm is raised with the start and end time of the gap and thanks to the Interpolation feature, the missing values are generated as seen in the image.
Warning
If the Signal's parent Device has its alarms suppressed, no alarms will be triggered for detected gaps.
Now let's take a second example:
Example 2 - Interpolation
Like in the previous example, the gap is detected between 0:15 and 1:45. The alarm is raised with the start and end times of the gap and the Interpolation functionality generates the missing values between the gap start and gap end.
To enable the interpolation of missing measurements, set the Interpolate property of the signal to true. The options of the Interpolate property are:
null: Gap Detection and Interpolation disabled;
false: Gap Detection enabled, Interpolation disabled;
true: Gap Detection and Interpolation enabled.
