The syntax descriptions refer to a POU with exactly one parameter, to which an argument is passed. As a result, the data type of the argument specifies the generic data type of the input variable. For example, arguments of the type BYTE, WORD, DWORD, LWORD can be passed to a type ANY_BIT input variable.

Syntax of function call:

<name of function> (<argument>)

Syntax of function block call

<name of function block instance> (<name of input variable> := <argument>)

Syntax of method call

<name of function block instance> . <name of method> (<name of input variable> := <argument>)

<argument>

Transfer variable

Example 

PROGRAM PLC_PRG
VAR
    byValue : BYTE := 16#AB;
    iValue : INT := -1234;
    xResultByte : BOOL;
    xResultInt : BOOL;

    fbComputeAnyByte : FB_ComputeAny;
    fbComputeAnyInt : FB_ComputeAny;

    fbComputeM1 : FB_ComputeMethod;
    fbComputeM2 : FB_ComputeMethod;

    byN : BYTE := 1;
    wBitField1 : WORD := 16#FFFF;
    wBitField2 : WORD := 16#0001;
    xInit : BOOL;
    xResult : BOOL;
END_VAR

//Implementation
xResultByte := funComputeAny(byValue);
xResultInt := funComputeAny(iValue);

xResult := funGenericCompare(wBitField1, wBitField2);

fbComputeAnyByte(anyInput1 := byValue);
fbComputeAnyInt(anyInput1 := iValue);

fbComputeM1.methComputeAnny(anyInput1 := byValue);
fbComputeM2.methComputeAnny(anyInput1 := iValue);
