Adding a Modbus Gateway¶
A Modbus TCP Gateway represents the network endpoint that the Enture edge device connects to over Ethernet to reach one or more Modbus devices. A gateway is only needed for Modbus TCP devices — serial (RTU) devices connect directly to the edge device's serial port and do not use a gateway.
Before you begin¶
- You need Engineer access to create a gateway.
- Know the IP address and port of the Modbus TCP gateway/converter, and which Hub (edge device) it is reachable from.
- If the gateway bridges to an RS-485 serial segment, have the serial settings (baud rate, parity, stop bit) ready.
Steps¶
1. Open the Control Panel¶
In the top navigation bar, open the Settings menu (gear icon) and go to Control Panel.
2. Click Add Modbus TCP Gateway¶
Click the + button. The Add Modbus TCP Gateway form opens.
3. Fill in the gateway details¶
| Field | Description |
|---|---|
| Name | A descriptive name for this gateway (e.g. Compressor Room Gateway) |
| IP Address | The IP address of the Modbus TCP gateway/converter |
| Port | The TCP port the gateway listens on (typically 502) |
| Hub ID | The edge device (hub) this gateway is reachable from. This can only be set when creating the gateway — it cannot be changed later. |
| Baud Rate | The serial baud rate used on the downstream RS-485 segment (e.g. 9600, 19200). Only relevant if the gateway bridges to serial devices. |
| Parity | The serial parity setting for the downstream segment: Even, Odd, or None |
| Stop Bit | The number of serial stop bits: 1 or 2 |
| Description | Optional notes about this gateway |
4. Save¶
Click Submit. The gateway is created and appears in the Control Panel gateway list.
Viewing gateway details¶
Hover over a gateway card in the list to see its full configuration.
Editing a gateway¶
Click the pencil icon on the gateway. You can update the Name, IP Address, and Port, then click Submit. The Hub ID cannot be changed after creation.
Deleting a gateway¶
Click the delete icon on the gateway. Deleting a gateway removes it from any devices that reference it — reassign or remove those devices first.
Next step¶
Once your gateway is set up, proceed to Adding a Modbus Device and select this gateway when configuring a TCP device.
