Network Instructions

will be transferred to the desired node. Each routing table is made up of a
local network table and a relay network table.
1,2,3...
1.
Local network table
This table shows the unit numbers and network addresses of the nodes
connected to the local PLC.
2.
Relay network table
This table shows the node numbers and network addresses of the first re-
lay nodes to destination networks that are not connected to the local PLC.
Communications to a Host Computer (Host Link)
By issuing a SEND(090), RECV(098), or CMND(490) instruction to a serial
port set to Host Link mode, the necessary Host Link header and terminator
will be attached to the FINS command and the command will be sent to the
host computer.
Note
Host Link communications can be sent through the network. In this case, the
FINS command travels through the network normally. When the command
reaches the Host Link system, the necessary Host Link header and terminator
are attached to the FINS command and the command is sent to the host com-
puter.
Serial Gateway Communications to a Component or Host Link Slave
It is possible to send FINS commands (or send/receive data) to a component
or Host Link Slave connected to the PLC through its serial port with the serial
gateway function.
• Sending to a Component
When a CMND(490) instruction is executed to a serial port that supports
the serial gateway function, the serial gateway function converts the com-
mand to a CompoWay/F, Modbus-RTU, or Modbus-ASCII command.
