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
    inVal32 : DWORD;
    bitNo   : SINT;
END_VAR

inVal32: 32 bit value

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

Example 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 example.
