Communication through Modbus output

There are different software systems and methods you can use to access or display the meter data. This can range from using a simple Modbus register interface to read stored values in the meter’s registers, to viewing intelligent information from the meter through an energy management system. The cable should be connected to terminals 23 and 24. The default communication address of the meter is 01.

The Modbus implementation used is Modbus basic (standard) with the following settings:

  • Baud rate 9600

  • 8 data bits

  • Even parity

  • 1 stop bit

The baud rate values can be changed to 4800, 2400, 1200. The parity can be set to none or odd. Data and stop bit cannot be changed.

NOTE:

When connecting the meter through a serial converter (RS-485) for testing, position an additional resistor (120 Ω/ 0.25 W) across the terminals (23 and 24) on the meter side.
