FB_CTRL_SCALE

FB_CTRL_SCALE 1:

This function block makes it possible to adjust the signal in a linear manner between two value ranges.

VAR_INPUT

VAR_INPUT
    fIn    : FLOAT;
END_VAR

Name	Type	Description
fIn	FLOAT	Input value for the function block

VAR_OUTPUT

VAR_OUTPUT
    fOut      : FLOAT;
    eErrorId  : E_CTRL_ERRORCODES;
    bError    : BOOL;
END_VAR

Name	Type	Description
fOut	FLOAT	Scaled output value
eErrorId	E_CTRL_ERRORCODES	Supplies the error number when the output `bError` is set.
bError	BOOL	Becomes TRUE, as soon as an error occurs.

VAR_IN_OUT

VAR_IN_OUT
    stParams    : ST_CTRL_SCALE_PARAMS;
END_VAR

Name	Type	Description
stParams	ST_CTRL_ SCALE_PARAMS	Parameter structure of the function block

stParams consists of the following elements:

TYPE ST_CTRL_SCALE_PARAMS:
STRUCT
    tCtrlCycleTime  : TIME := T#0ms; 
    tTaskCycleTime  : TIME := T#0ms; 
    fInMin          : FLOAT;
    fInMax          : FLOAT;
    fOutMin         : FLOAT;
    fOutMax         : FLOAT;
END_STRUCT
END_TYPE

Name	Type	Description
tCtrlCycleTime	TIME	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	TIME	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.
fInMin	FLOAT	Minimum of the input value
fInMax	FLOAT	Maximum of the input value
fOutMin	FLOAT	Minimum of the output value
fOutMax	FLOAT	Maximum of the output value
