CtrlLagDelay (FB)

FUNCTION_BLOCK CtrlLagDelay EXTENDS AbbETrig3

This signal processing function block processes the input signal with Lag algorithm with defined delay cycle.

Transfer Function = U(s)/ E(s) = Gain * [ 1 / (1+ Ti * s ) * e - Ls ]

3: Input of the signal to be processed by CtrlLagDelay function block

Mode

BYTE

1
4: Process mode:

  • 0 = Out = In = Disable Lag Delay Function

  • 1 = Out = Gain*1/(1+Ti*s)*e-Ls*In = Start Lag Delay Function

4: Propotional gain of CtrlLagDelay function block

Ti

REAL

1

5: Lag time of CtrlLagDelay function block (Unit: Second) 10000>=Ti>= 0.1

DelayCycle

INT

1

6: Delay cycle of CtrlLagDelay function block (600> = DelayCycle >= 0). Delay cycle depends on the cycle time of the task configuration, that is, Delay before integration = Delay cycle * Task cycle time
