PLC-API 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. tTv : Differentiation time constant tTd : Damping time constant fOutMaxLimit : Upper limit at which the output of the D element is limited. fOutMinLimit : Lower limit at which the output of the D element is limited. Requirements 5.3.2 FB_CTRL_HYSTERESIS The function block provides a hysteresis transfer element in a functional diagram. Transfer function: VAR_INPUT VAR_INPUT fIn : FLOAT; bManSyncValue : BOOL; bSync : BOOL; eMode : E_CTRL_MODE; END_VAR fIn : Input of the hysteresis element. bManSyncValue :
Input through which the hysteresis element can be set to one of the two junctions. bSync : A rising edge at this input sets the hysteresis element to the value fManSyncValue. eMode : Input that specifies the operation mode [ } 16] of the function block.
