INSTALLATION

  • Mount the RS232 Extension on the DIN rail
  • Connect 24VDC power supply, but do not switch on until the whole installation is completed
    (We recommend looping through the Miniserver)
  • Connect the Loxone Link
  • Connect the RS232 Extension to an RS232 device.
  • Note: If it is the last extension, terminate the Loxone Link with a 120Ω resistor (Included with the Miniserver)
  • Turn on the power supply
  • After a few seconds, the left LED will flash green if the extension is already configured, or orange if not

SETTING UP A FRONIUS SOLAR INVERTER

The values from a Fronius Inverter can be read using Fronius’s RS232 Converter Box and Loxone’s RS232 Extension.

SELECT THE PROTOCOL

Connection Parameters:
Auto-baud rate (2400, 4800, 9600, 14400, 19200), 8 data bits, 1 stop bit.
In order for the sensor values to be transmitted, you must select the ‘Fronius’ protocol.

CHANGE ID IN THE SETUP MENU

The inverter responds only to a value-request. These requests are saved in the actuators, therefore a pulse at the actuator writes the current value to the corresponding sensor.
In this request-command the inverter’s ID is included (which can be changed in the setup menu). By default, a request-command saves the ID 01.

The following measured values are sent with decimal places. The decimal places falsify the measured values to the power of 2 or 3 respectively:

2 Decimal Places:
Get Yield – DAY
Get Yield – YEAR
Get Yield – TOTAL

1 Decimal Place:
Get operating Hours – DAY

These sensor values can be corrected by the divider function block. Please note that the operating time is given in minutes.
