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 sta-
tion 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.
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.
Slave Station
Slave station data registers D912 through D1271 can be used as ordinary data registers.
