2 PARAMETER SETTINGS

2.3 Application Settings

Network Dynamic Routing

Set when using the dynamic routing.

Setting "Network Dynamic Routing" is possible only when values are set in "Network Number" and "Station No." under "Own

Node Settings" of "Basic Settings". ( Page 243 Communications by Network No./Station No.)

For details, refer to the following.

Page 385 Communications with Different Networks

When the communication path is set in "Routing Setting" of "CPU Parameter", setting of "Routing Setting" has

a priority.
