Routing parameter setting
Set routing parameters in the following cases.
• When modules other than MELSEC iQ-R series exist in the communication path
• When an Ethernet device needs to be connected to a module that does not support routing parameters
■
When modules other than MELSEC iQ-R series exist in the communication path
To set routing parameters, refer to the following.

■ When an Ethernet device needs to be connected to a module that does not support routing
parameters
When an Ethernet device needs to be connected to a module, such as an Ethernet adapter module, that does not support
routing parameters, set the routing parameters so that communications are transmitted through the master station.
Communications from a module that does not have the routing parameters are automatically transmitted through the master
station. The communication paths must be the same for data sending and receiving; therefore, set the routing parameters so
that communications are transmitted through the master station.
