Adding a Modbus Device¶
A Modbus Device represents a single physical device — a meter, sensor, VFD, or PLC — that Enture reads over Modbus TCP or RTU. All Modbus parameters (registers) you want to read from that device are added as children of this device.
Before you begin¶
- A Workspace must already exist for the device to be assigned to.
- For Modbus TCP devices, the Modbus Gateway it connects through must already exist.
- You need the device's Slave ID (also called Unit ID) on the Modbus bus.
- You need Engineer access to create devices.
Steps¶
1. Open the Devices section¶
In the left sidebar, go to Digital Twin → Devices.
2. Click Create Modbus Device¶
Click the + button and select Create Modbus Device. The creation form opens.
3. Fill in the device details¶
| Field | Description |
|---|---|
| Workspace | The workspace this device belongs to |
| Name | A descriptive name for this device (e.g. Main Energy Meter) |
| Slave ID | The device's Modbus Slave/Unit ID on the bus |
| Device Type | The type of device from the searchable list (e.g. energy meter, VFD, PLC). Selecting a known device type can pre-fill common parameter templates. |
| Connection Type | Modbus TCP or Modbus RTU |
| Modbus Gateway | (Shown only when Connection Type is Modbus TCP) Select the gateway this device is reachable through — see Adding a Modbus Gateway |
| Description | Notes about this device |
| Make | The device manufacturer |
| Model | The device model number |
4. Save¶
Click Create. The device is created and appears in the Devices list.
What happens next¶
The Enture edge device at your facility receives the new device configuration within approximately 30 seconds.
You can now add parameters to this device — see Adding Modbus Parameters.
Updating a Modbus Device¶
- Navigate to Digital Twin → Devices and find the device.
- Open the device and click Edit.
- Update the fields and click Update.
The edge device applies the new settings within approximately 30 seconds.
