Description:
− The function determines the average value over a period of time. The output value is up-
dated with each cycle.
− Master Reset is FALSE: The output value is the average of all input values since the last
negative edge from Master Reset.
− Master Reset is TRUE: The output value is the same as the input value.

Time unit:
1: [ms], 2: [s], 3: [min]
Description:
The output value follows the input value at a limited ramp gradient.
− P1 indicates the percentage by which the output value may change per unit of time.
− P2 indicates the unit of P1:
1: in percent per millisecond [%/ms],
2: in percent per second [%/s],
3: in percent per minute [%/min].
− Master Set: TRUE sets the output to the start value. The start value can be defined via input
I2.
− Master-Reset: TRUE sets output O1 to 0.
− Master Reset has priority over Master Set.
