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