Example of an FT-PT1 signal smoothing filter configuration on a device display
When using the function block in the circuit diagram for the first time, use OK to auto-
matically enter the general display of function block parameters, as shown in the figure
on the left. Enter the function block settings here.

ter
Function block: Signal smoothing, number 17
+ Parameter set can be called via the PARAMETERS menu
>I1 Input value: -32768… +32767
>T
G
Recovery time: 0… 65535 resolved in 100 ms
Example: The value 250 is processed in the function block as 25 s.
