calculated COUNT of an attribute
Count of values in tables:
In tables there are some calculation (MIN, MAX; AVERAGE, RANGE, STDEV,...) available, but no COUNT - I´m really missing it for online reporting, for example: number of cycles or produced pieces based on suitable attributes/tags
Does count here refer to the number of events/data points over the time range? Or are you looking for a calculation of the total (the sum of the values of the events) over the time range?
I would like to be able to track "count" as for example change in status! on/off
No of events. Configure between total changes or changes from off to on. Ex. How many times has a pump started.

For us, the number of events
