PLC-API bOutNegIsActive : TRUE indicates that fIn eErrorId : Supplies the error number [ } 16] when the bError output is set. bError : Becomes TRUE, as soon as an error occurs. VAR_IN_OUT VAR_IN_OUT stParams : ST_CTRL_SPLITRANGE_PARAMS; END_VAR stParams : Parameter structure of the function block. This consists of the following elements: TYPE ST_CTRL_SPLITRANGE_PARAMS: STRUCT tCtrlCycleTime : TIME := T#0ms; (* controller cycle time [TIME] *) tTaskCycleTime : TIME := T#0ms; (* task cycle time [TIME] *) bInvertNegOutput : BOOL; bDisablePosOut : BOOL; bDisableNegOut : BOOL; END_STRUCT END_TYPE tCtrlCycleTime : Cycle time with which the control loop is processed.
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. bInvertNegOutput : fOutNeg is inverted when this parameter is TRUE. bDisablePosOut : The output fOutPos is disabled and always 0.0. bDisableNegOut : The output fOutNeg is disabled and always 0.0. Requirements 5.8.9 FB_CTRL_STEPPING_MOTOR_OUT This function block generates a control value for a stepper motor.
