Nodes
A node is an external Modbus device. In the default configuration, there is a node device called ModProBus. ModProBus is the device itself, its own node, and it reads values from the device's own registers.
Important: The Slave ID in the Modbus Configuration under the Devices tab and the Device ID from RF Modems must have the same value as the Slave ID of the ModProBus Node.
The maximum number of configurable nodes is 10.
