Setting Routing Tables Section 7-4
7-4-8 Example Routing Table Settings
This section shows examples of routing table settings.
Example 1 The example below shows local network table settings when multiple CPU
Bus Units are mounted in a single CVM1 or CV-series PLC.
Do not register SYSMAC BUS/2 Master Units and BASIC Units in local net-
work tables because these Units do not connect to networks.
Example 2 The following example show the settings for a relay network table connecting
three networks.
On closer examination of the relay network table for PLC#, we see that the
relay network is B and the relay node is c when network A is the destination,
and that the relay network is B and the relay node is e when network C is the
destination.
