A. The Message is Originated

A Modbus Plus node originates a message with the five--byte Modbus Plus path 25.8.17.33.0. The message is addressed to the bridge at node address 25, specified in the first routing byte.

Bridge 1 (node 25) receives the message and opens its internal path 8. This path is specified in the second routing byte.

B. Bridge 1 Maps the Message to TCP/IP

Bridge 1 indexes into its TCP Mapping table at location TCP_17, specified by the third routing byte. Location 17 contains the IP address 205.167.8.10. The bridge forwards the message to this IP address, a second bridge.

C. Bridge 2 Maps the Message to Modbus Plus

Bridge 2 receives the message and indexes into its Modbus Plus Mapping table at location MBP_33, specified by the fourth byte of routing in the original message. Location 33 contains the Modbus Plus routing path 12.0.0.0.0 to a node on the Modbus Plus network at Bridge 2.

D. The Message is Delivered

The message is delivered to the destination node 12 on the Modbus Plus network. The node acts upon the Modbus command embedded in the message.
