Once you have done the I/O table to register all of modules to CPU, you will see I in front of input points, Q in front of output points, actually, it can also be changed to display by Japanese way, like Mitsubishi or Panasonic, using X and Y to represent outputs and inputs as well.
Back to original question. Omron calls CJ series and CS1 series PLC addressing as dynamic allocation, the rule is always from left to right, normally start from 0, 0.00-0.15, and keep counting up, and so on.
If you change your module‘s location, you really need to change your PLC program addressing as well.
Hope above info will help.
Sorry for typing English as I don‘t have Chinese input software on my computer.
