PLC-API Step response: VAR_INPUT VAR_INPUT fIn : FLOAT; fManValue : FLOAT; eMode : E_CTRL_MODE; bHold : BOOL; END_VAR fIn : Input value of the PT2 element. fManValue : Input value that is output in manual mode. 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 : Output of the PT2 element. 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_PT2_PARAMS; END_VAR stParams : Parameter structure of the PT2 element. This consists of the following elements: TYPE ST_CTRL_PT2_PARAMS : STRUCT tCtrlCycleTime : TIME := T#0ms; (* controller cycle TS4100 93 Version: 1.1
