● When an Ethernet device is connected to a module, such as an Ethernet adapter module, that does not support the
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 routes must be the same for data sending and receiving; therefore, configure the
setting so that communications are transmitted through the master station.
