GETBIT32

GETBIT32 1:

The function returns the status of the bit specified by a bit number in the 32-bit value that is passed to it as a boolean resulting value. The input value is not altered.

FUNCTION GETBIT32 : BOOL

VAR_INPUT

VAR_INPUT
    inVal32         :DWORD;
    bitNo           :SINT;
END_VAR

inVal32: the 32-bit value;

bitNo: the number of the bit to be read (0-31). This number is internally converted to a modulo 32 value prior to execution;

Sample of calling the function in FBD:

GETBIT32 2:
Bit 2 in the input value '16#04' is queried and assigned to the boolean variable aGetBitResultVar. The query returns TRUE in this sample.
