PLC-API Transfer function: VAR_INPUT VAR_INPUT fIn : FLOAT; fManSyncValue : FLOAT; bSync : BOOL; eMode : E_CTRL_MODE; bHold : BOOL; END_VAR fIn : Input of the I element. fManSyncValue : Input to which the I-element can be synchronised, or whose value is the present at the output in Manual Mode. bSync : A rising edge at this input sets the integrator to the value fManSyncValue. eMode : Input that specifies the block's operating mode. bHold : A TRUE at this input holds the integrator fixed at the current value, independently of the input fIn. VAR_OUTPUT VAR_OUTPUT fOut : FLOAT; bARWactive : BOOL; eState : E_CTRL_STATE; eErrorId : E_CTRL_ERRORCODES; bError : BOOL; END_VAR fOut :
Output of the I element. bARWactive : A TRUE at this output signals that the integrator is being restricted. eState : State of the function block. nErrorID : Returns the ADS 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_I_PARAMS; END_VAR stParams : Parameter structure of the I element. This consists of the following elements: TYPE ST_CTRL_I_PARAMS : STRUCT tCtrlCycleTime : TIME := T#0ms; (* controller cycle time *) tTaskCycleTime : TIME := T#0ms; (* task cycle time *) tTi : TIME := T#0ms; (* integral action time Ti *) fOutMaxLimit : FLOAT := 1E38; (* maximum output limit *) fOutMinLimit :
FLOAT := -1E38; (* minimum output limit *) END_STRUCT END_TYPE TS4100 28 Version: 1.1
