Nodes
Rules, Nodes tabs redirect to this page.
Node is an external Modbus device. In the default configuration, there is a node called ModProBus on the device. ModProBus is the device itself, its own node, and reads values from the device's own registers.
Important: The Slave ID from Modbus Configuration in 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 configurable number of Nodes is 10.
Users can add new nodes by clicking the Add Node button.
| Parameter | Description | Values |
|---|---|---|
| Index | The index value of the Node. Automatically assigned by the device, cannot be changed. | |
| Status | The status of the Node. | Active Passive |
| Name | The name of the Node (Maximum length 16) | |
| Endianness | The endianness of the device. | ABCD DCBA BADC CDAB |
| Poll time (seconds) | The interval for reading data from the Modbus device. | |
| Timeout (seconds) | The timeout duration while reading data from the device. | |
| RF Modem | The RF Modem from which data is to be read. | |
| Modbus Device | The Modbus Device from which data is to be read. | |
| Function Code | The function codes required to read data from the Modbus RTU or Modbus TCP device. | 01 Read Coils (0x) 02 Read Discrete Inputs (1x) 03 Read Holding Registers (4x) 04 Read Input Registers(3x) |
| Address | The starting address of the registers to be read. | |
| Quantity | The number of registers to be read. |
- When using Mesh mode, Timeout must be more than twice the maximum communication time value.
