PLC-API fManSyncValue : Input value that is output at the output in manual mode. bSync : Reserve. eMode : Input that specifies the operation mode [ } 16] of the function block. bHold : A TRUE at this input will hold the internal state (and therefore also the output) constant at its current value, independently of the input value. VAR_OUTPUT VAR_OUTPUT fOut : FLOAT; eState : E_CTRL_STATE; eErrorId : E_CTRL_ERRORCODES; bError : BOOL; END_VAR fOut : lead/lag filter output. eState : State of the function block. 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_LEAD_LAG_FILTER_PARAMS; END_VAR stParams : Parameter structure of the lead/lag filter. This consists of the following elements: TYPE ST_CTRL_LEAD_LAG_FILTER_PARAMS:STRUCT tCtrlCycleTime : TIME := T#0ms; (* controller cycle time [TIME] *) tTaskCycleTime : TIME := T#0ms; (* task cycle time [TIME] *) tT1 : TIME := T#0ms; (* T1 *) tT2 : TIME := T#0ms; (* T2 *)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. tT1 : T1, see G(s) tT2 : T2, see G(s) Requirements TS4100 86 Version: 1.1 Development environment Target system type PLC libraries to be linked TwinCAT v2.8 PC (i386) TcControllerToolbox.lib TwinCAT v2.9, build 947 onwards BC [} 10] TcControllerToolbox.lb6 TwinCAT v2.9, build 956 onwards BX [} 10] TcControllerToolbox.lbx
