SETBIT32

SETBIT32 1:

The function sets the bit specified by a bit number in the 32 bit value that is passed to it and returns the resulting value.

FUNCTION SETBIT32 : DWORD

VAR_INPUT
    inVal32 : DWORD;
    bitNo   : SINT;
END_VAR

inVal32: 32 bit value that is to be modified

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

Example of calling the function in FBD:

SETBIT32 2:

This sets bit 31 of the input value 0. The result is the (hex) value “80000000”.
