Routing Function - Mitsubishi Electric MELSEC Q Series Reference Manual

4.2.3

Routing function

This function allows transient transmissions to stations located on other networks in a multi-network system.
By setting a routing parameter for a relay station on the own network, transient data can be sent to another network
through the relay station. (
