Modbus in Enture

Modbus is the most widely used protocol for connecting meters, sensors, variable frequency drives (VFDs), and PLCs. Enture supports both Modbus TCP (Ethernet) and Modbus RTU (serial RS-485/RS-232) devices.

How Enture uses Modbus

  • A Modbus TCP Gateway represents the network endpoint (IP address and port) that the Enture edge device connects to. Serial (RTU) devices are read directly by the edge device's serial port and do not require a gateway.
  • A Modbus Device represents a single physical device (meter, sensor, VFD, PLC) reachable through a gateway (TCP) or directly on the serial bus (RTU), identified by its Slave/Unit ID.
  • Modbus Parameters map individual registers on the device to trackable data points in Enture.

Once configured, the Enture edge device connected to your facility polls the configured registers continuously and streams the values to the platform.

Typical setup workflow

  1. Add a Modbus TCP Gateway (TCP devices only) — see Adding a Modbus Gateway.
  2. Add a Modbus Device — assign it to a workspace, set its connection type (TCP or RTU) and Slave ID — see Adding a Modbus Device.
  3. Add Modbus Parameters — for each register you want to monitor, add a parameter with its address and data format — see Adding Modbus Parameters.

Data flows automatically once the edge device picks up the configuration (within approximately 30 seconds).

A Modbus Params View is also available under Settings → Engineering for bulk-auditing Modbus parameter configuration across your organisation.
