Buffer Memory
ON/OFF information from the remote I/O station/remote device station/intelligent device station to the
master station
3) The input status of the input (X) in the remote I/O station and the remote input (RX) in the remote device
station/intelligent device station is automatically (for each link scan) stored in the buffer memory "remote
input (RX)" in the master station.
4) The PLC receives the input status stored in the buffer memory "remote input (RX)" using the FROM
instruction.
