Modbus Support Package

The Modbus support package enables Engee to work with devices using the Modbus protocol using library blocks Modbus. The package runs on top of the subsystem Engee.Integrations and supports exchange via Modbus TCP (Ethernet) and Modbus RTU (serial port).

Requirements

  • The Engee subsystem is installed and running.Integration.

  • Modbus TCP: Device IP address and port, network availability.

  • Modbus RTU: Serial port name and line parameters; drivers for USB-Serial (Windows) if necessary.

  • ID of the slave device (Unit/Slave ID).

Quick start

  1. Install or connect the Engee subsystem.Integrations as shown in article.

  2. Select the sharing mode:

    • Modbus TCP: specify the IP address, port and Unit ID in the parameters of the blocks.

    • Modbus RTU: specify the port and parameters of the connection and Unit ID.

  3. Now you can use blocks from the library Modbus.
