Additional remark:
1. If the values in m
1
and m
2
exceed the range, the operation error occurs, the instruction is not
executed, SM0 is ON, and the error code in SR0 is 16#2003.
2. If S~S+n-1 exceed the device range, the instruction is not executed, SM0 is ON, and the error
code in SR0 is 16#2003.
3. If the value in n exceeds the range, the operation error occurs, the instruction is not executed,
SM0 is ON, and the error code in SR0 is 16#200B.
4. Due to the fact that the use of the instruction TO decreases the execution efficiency of the CPU
module and that of the I/O module, users should use it less often.
5. The descriptions of the error codes:
