 CPU Interface Registers for Low-speed Scan
You can set register sizes of up to 2,048 words for both the input and output registers for the CPU interface
registers for the low-speed scan. Set a value that is an integral multiple of 16 words (32 bits).
The data transfer size is the smaller of the I/O sizes of the Main CPU Unit and Sub CPU Unit. We recom-
mend that you set the same I/O sizes for the Main CPU Unit and Sub CPU Units to make programming
easier to understand.
