This must be greater than or equal to the TaskCycleTime. The function block uses this input value to calculate internally whether the state and the output values have to be updated in the current cycle. tTaskCycleTime : Cycle time with which the function block is called. If the function block is called in every cycle this corresponds to the task cycle time of the calling task. fKp :
Controller amplification / transfer coefficient tT1 : Time constant T1 tT2 : Time constant T2 Requirements 5.5.10 FB_CTRL_PT2oscillation The function block provides an oscillating PT2 transfer element in the functional diagram.
