CSETBIT32
The function sets/resets the bit specified by a bit number in the 32 bit value that is passed to it and returns the resulting value.
FUNCTION CSETBIT32 : DWORD
VAR_INPUT
inVal32 : DWORD;
bitNo : SINT;
bitVal : BOOL;
END_VAR
inVal32: 32 bit value
bitNo: Number of the bit to be set or reset (0-31). This number is internally converted to a modulo 32 value prior to execution.
bitVal: Value to which the bit is to be set or reset (TRUE = 1, FALSE = 0)
Example of calling the function in FBD:
Bit 15 in the input value 16#80000000 is set to 1. The result (16#80008000) is assigned to the variable CSetBitResultVal.
