Function
Binary numbers are converted to gray code equivalents.
S is the BIN data source or data variable unit to be converted, in the range 0 to 32,767 in 16-bit operation
or 0 to 2,147,483,647 in 32-bit operation. When this range is exceeded, M8067 and M8068 are set to ON
and the instruction is not executed.
D is the unit that stores the gray code value after conversion.
Algorithm for BIN-to-gray code conversion: XOR operation is performed on every bit starting from the
rightmost bit and a left-hand bit to get the gray code value. The leftmost bit remains unchanged (with a
value of 0).
Example:
X0
