MGate MB3000 Modbus Gateway User Manual 56
Auto Device Routing (patented)
The Moxa Modbus gateways provide an auto routing mechanism that eliminates the burdensome task of
setting the slave ID table manually. Now, users no longer need to set the bothersome routing table. The
Moxa Modbus gateways will help you detect and route correctly.
Click the checkbox for Auto Device Routing , and a message window will pop up.
Click Yes to delete the existing (factory default or user-set) routing table; the auto-routing mechanism will
automatically find the correct serial port that connects the target Modbus device. Moreover, if a device is
added to the gateway later, the gateway can also route it correctly. Note that the routing table will be
cleared as the warning message. The Slave ID table is then shown as in the figure below.
Users can only check the result of auto-detect routing table through the web console.
This snapshot shows the routing mechanism is in Auto mode, and the gateway detects that slave ID 1 and 2
are connected in port 1 and slave ID 3 is connected in port 2.
If a conflict exists, the table will show the error in red.
For example, two Modbus devices with the same slave ID are connected in serial port 1 and port 2.
