Data Register Allocation for Transmit/Receive Data
The master station has 12 data registers assigned for data communication with each slave station. Each slave station has 12 data
registers assigned for data communication with the master station. When data is set in data registers at the master station
assigned for data link communication, the data is sent to the corresponding data registers at a slave station. When data is set in
data registers at a slave station assigned for data link communication, the data is sent to the corresponding data registers at the
master station.

If any slave stations are not connected, master station data registers which are assigned to the vacant slave stations can be used
as ordinary data registers.
