Transfer of RS-485 data among HD-PLCs

4.4.3.1

When 485-Master is connected to PLC-Master

· Maximum performance can be obtained when 485-Master is connected to PLC-Master.

· From the PLC, to which 485-Master is connected, transfer the command by unicast to each

PLC-Terminal which 485-Slave is connected.

· The response to the PLC, to which 485-Master is connected from PLC-Terminal is also

transferred with unicast.

· When received by 485-Master, PLC-Master transfers the command by unicast to each

PLC-Terminal to which 485-Slave is connected. However, it excludes the source

PLC-Terminal from which the response is sent.

Specific case: 485-Master 1 communicates with 485-Slave 3

1) 485-Master 1 sends a command to 485-Slave 3

2) Command transfer from PLC-Master to PLC-Terminal (485-Slave 2/3/4) with unicast

3) 485-Slave 3 sends a response to 485-Master 1

4) Response transfer from PLC-Terminal 3 to PLC-Master 1 with unicast

5) Command transfer to PLC-Terminal (485-Slave 2/4) by PLC-Master 1 with unicast

6) 485-Master 1 receives the response
