Buffer Memory
Read from remote register (RWr)
9) The data of the remote register (RWr) in the remote device stations is automatically (for each link scan)
stored in the buffer memory "remote register (RWr)" in the master station.
10) The PLC receives the data of the remote register (RWr) in the remote device stations stored in the buffer
memory "remote register (RWr)" using the FROM instruction.
