4.7.13 Average
This software channel calculates the average from the source values.
Moving, arithmetic average : This arithmetic average is calculated from a con-
figured series of values numbering from 2 to 1000 values.
Moving means that each new value from the source is stored to the data series and
triggers calculation of the average from the accumulated values and output of the
result. If the number of values reaches the specified maximum, the data series is
then full and a new value from the source then overwrites the oldest value.
A device reboot or a configuration change deletes all the accumulated values.
Block averaging : This option provides two methods of averaging:
l
Arithmetic average : The arithmetic average, also called the mean, is the sum
of all values of a data series divided by the number of values.
l
Vector average : The vector average is the average for a unit circle. The
method is used, for example, for mass flow rates in air conditioning engin-
eering.
Edge triggering (only with block averaging): The configured average type is cal-
culated at the time of the trigger event for all values of the data series that have
accumulated between two trigger events. The result is output following cal-
culation.
Level triggering (only with block averaging): When a level moves from an active to
inactive state, the average is calculated from the values accumulated during the
active level period.
