Configuration The public display card / box can be configured for two different display
types using the „Solar.access“ software.
Display type A:
The „Display Type A“ setting is used for alphanumeric Fronius displays or
Rico displays connected to the display card / box. The public display card
/ box is programmed to recognize the display type automatically. No other
settings are required.
Important If the display is to show the irradiance, module temperature or
outside temperature values, the corresponding sensors must be con-
nected to the sensor card / box with address 1.
Additional, optional settings may also be made using „Solar.access.“
Detailed information on settings options can be found in the chapter
„Solar.access.“
Important The public display card is already integrated into the Fronius
Public Display, which reduces the cabling effort considerably.
Display type B:
When the „Display Type B“ setting is selected, the public display card /
box sends a defined data record via the serial interface.
Interface parameters:
- 2400 Baud
- 8 data bits
- 1 stop bit
- No parity
- Handshake off
The data record contains the following values:
- Total energy (kWh)
- Today’s energy (kWh)
- Current output (kW)
- Irradiance (W/m²) .... only available when a corresponding sensor is
connected to the sensor card / box with address 1.
The data record output corresponds to the following format:
- Total energy: 6-digit, no decimal point, in KWh
- Today’s energy: 4-digit, no decimal point, in kWh
- Current output: 4-digit, two before and two after the decimal point, in
kW (the decimal point is not transferred since it is always in the same
place)
- Irradiance: 4-digit, no decimal point, in W/m²
