Nodes
Rules, Nodes tabs redirect to this page.
Node is an external Modbus device. In the default configuration, there is a node device named DC620_Dual. The DC620_Dual 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 section of the Devices tab must have the same value as the Slave ID of the DC620_Dual Node.
The maximum configurable number of Nodes is 32.
Users can add new nodes by clicking the Add Node button.
