Description:
The input value at I1 is filtered.
O1 = − O 2 = 1 I ×
− The filter time constant P1 indicates how long it takes in the case of a constant input value
until the output value (starting from zero) reaches 63% of the input value.
− Master Set: TRUE sets the output to the start value. The start value can be defined via input
I2.
− Master-Reset: TRUE sets the output to 0.
− Master Reset has priority over Master Set.
If the filter is to be stopped, input 2 must be combined with the output and the Master Set in-
put (I3) must be activated.
I2=O1, I3=TRUE
Note:
Percentages [%] have two decimals.
For example: Value 12345
