Nodes
Rules, Nodes tabs redirect to this page.
Node is an external Modbus device. In the default configuration, there is a node device called EdgePro. EdgePro is the device itself, its own node, and reads values from the device's own registers.
Important: The Slave ID from the Modbus Configuration in the Devices tab and the Device ID from RF Modems must have the same value as the Slave ID of the EdgePro Node.
The maximum configurable number of Nodes is 10.
Users can add new nodes by clicking the Add Node button.
