Routing Table Examples Section 5-3
Routing Tables on PLC 2
Routing Tables on PLC 3
Routing Tables on PLC 4
Routing Tables on PLC 5
Routing Tables on PLC 6
Routing Tables on PLC 7
Using Routing Tables The following descriptions shows how the above routing tables are used for
data transmission from PLC 1 to PLC 6 using a SEND(90), RECV(98), or
CMND(490) instruction.
1,2,3... 1. PLC 1 checks its relay network table, and sends the data to node 5 (PLC
3) on network 10, to send the data to network 30, on PLC 6.
2. PLC 3 receives the data from PLC 6, checks its local network table, and
sends the data to node 5 (PLC 6) via CPU Bus Unit with unit number 7,
which is connected to network 30.
3. PLC 6 checks its local network table and confirms that the data transmitted
to node 5, network 30, is for PLC 6. Then PLC 6 retrieves the data.
