2.8 Communications with an OMRON PLC (FINS Communications Service)
Routing
2-221
Routing
This section describes the restrictions that apply when sending and receiving I/O messages, and when
using the MSG-SNDE and MSG-RCVE functions between the MP3000 and OMRON PLCs connected
across different networks.
Using the MP3000 as the Master
When the MP3000 master sends messages using I/O message communications or the MSG-SNDE func-
tion, the destination node must be connected to the local network. A node connected to another network
cannot be specified as the destination.
Using the MP3000 as a Slave
When the MP3000 acts as a slave and uses automatic reception or the MSG-RCVE function to receive
messages that are routed, it can also receive messages from a node on another network. The MP3000 slave
can also return responses to the source.

Message sent from a node on another network.
The MP3000-series Machine Controller sends the response by swapping the addresses of the source and destination nodes.
