Aggregation Processor

The “Aggregation Processor” is installed with the UA Office Link Application. The processor calculates the maximum, minimum and average of all input values. If all or part of the input values are one-dimensional arrays then the summarized values are calculated over all array elements of the input values.

If any input value is of “uncertain” quality then the output values will also be of uncertain quality.

If any input value is of “bad” quality then all output values will also be of bad quality.

Add to Task

Add the “Aggregation Processor” to a task by dragging it from the “Build” panel onto the task’s “Task Builder” panel.
