This module is used to average chronological measured values. The average value is calculated cyclically (in the case of active start release - Input 1) after expiry of each time interval (Input 2) and output at Output 3. The average value is calculated from the "current value" (Input 3) and the "last value" (value at Input 3 at the start of the time interval - previous current value). After the time interval expires, Output 1 sends the respective current value to Output 2 and a 1 to the control output (Output 4). This output can be used in order to reset a counter to 0 after expiry of the time interval. Output 1 additionally sends the current value once at the start of the module (available optionally - is normally not required because the current measured value is already available). Output 5 informs about an increasing, constant or falling tendency of the average value.
