Buffer Memory
Word information from the master station to the remote device station/intelligent device station
7) The PLC writes the word information to be transmitted to the remote device station and the intelligent
device station to the buffer memory "remote register (RWw)" in the master station using the TO
instruction.
8) The information of the buffer memory "remote register (RWw)" is automatically (for each link scan) stored
in the remote register (RWw) in the remote device station and the intelligent device station.
