The parametering of the Function block is achieved through specification of the boost factor GAIN as well as the parametering of the delayed time constants LAG.
The unit step at the input IN (jump at the input IN from 0 to 1.0) is followed by the output OUT with a lag time. Along an e-function
it will approximate the value
.
Two operating modes can be selected through the TR_S parameter input.

The Function block will be handled as " Parametering" describes. |

The tracking value TR_I is transferred directly to the output OUT.

The diagram shows an example of the jump response of the LAG_FILTER function block. The input IN jumps to a new value and the output OUT follows the input IN along an e-function.
