DERIVATE
Differentiates a real value.
Arguments | ||
RUN | BOOL | Mode: TRUE=normal / FALSE=reset |
XIN | REAL | Input: any real value |
CYCL | TIME | Sampling period. Possible values range from 0ms to 23h59m59s999ms. |
XOUT | REAL | Differentiated output |
If the "CYCLE" parameter value is less than the real duration of the cycle time in the
virtual machine, the sampling period will use the real duration of the cycle time.
Example
(* FBD program using the DERIVATE

(* ST
Equivalence: DERIVATE1 instance of DERIVATE block
*)
DERIVATE1(manual_mode, sensor_value, t#100ms); derivated_value := DERIVATE1.XOUT;
