Slave ID Map
The MGate MB3180 accepts the Modbus Unit ID as a virtual slave ID and
monitors devices with these virtual slave IDs.
By default, the CGW-MB assigns a Modbus Unit ID to each node on the NFN
network. The ID is equal to node number of the node. They can be changed,
but should be within 1 to 99.
Refer to the
7.16 "To Configure the Modbus Settings"
section for more
information about changing a Modbus Unit ID.
