SMARTBox

Overview

Smartbox, based on the Telit Chipset HE910 is a ready to use solution for connecting Modbus devices to the Cumulocity Fieldbus Cloud. It provides a Master Slave Communication on RS485 for connecting up to 20 devices as well as 10 Sensors (Current ,Temperature, Pressure). Easy configure the SetUp of building automation fielddevices like pumps, e-meters, Airhandling units in the Cumulocity Fieldbus cloud or connect different sensortypes to the box. Using the Smartrest protocol the terminal comes up with a low traffic solution for decentralized applications. For the Smartbox there is a customized user interface available made for easy handling the sensors and showing graphs for consumption and temperatures.

Overview

Wire your Modbus RTU RS485 Network

Wire the Modbus RTU RS485 network: Modbus RTU

Wire the Sensors: Sensors By default NTC temperature sensors are configured.

Configure the Terminal

By default the terminal supports cloud fieldbus from Cumulocity. To use it you should:

  • Subscribe your account to the Cloud Fieldbus app by contacting support.
  • Configure the terminal:
    1. Power on the Terminal.
    2. Configure the Terminal's APN by sending an SMS to Terminal's SIM card with the following syntax: GPRS=APN,username,password (e.g. GPRS==public4.m2minternet.com,,)

Registering the Terminal in Cumulocity

In the cumulocity Cloud Fieldbus app go to the menu and there find Devices -> Registration. Enter the Terminal's IMEI as an ID. The IMEI is printed on the devices itself:
