I connect multiple UTs as CC-Link slaves. How should I assign PLC CPU registers?

Open registers for the number of proprietary stations per unit.
For example, if there are 3 CC-Link Ver. 1 stations are occupied, the bit area occupies 96 bits per station and a word area of 12 words per station.
If the refresh device of the word area remote register is assigned to DO-, the top of the word area of the second UT would be D12-.
