Valid range: 1–32.
If the value is out the range, the instruction
does not modify the operand.
Valid range: 0 and 1–240.
If the value is greater than 240, the

value is less than or equal to 0, the original
station address is not changed.
Supports 16#01, 02, 03, 04 and 17.
If the value exceeds the valid range, the
instruction does not modify the operand. If
S =16#17, it is processed as 16#17.
