Fronius

The Fronius interface communicates via Ethernet with a Fronius inverter. This allows the energy data to be displayed in real time. In addition, it is possible to detect a fault on the device.

How It Works

The data is queried cyclically every second by Antcas Control via HTTP. If a value has changed, it is sent to the PLC.

If multiple inverters are used, they can be queried with the corresponding device address. Each individual device uses its own interface in Antcas Control for this purpose.

Variables

In case an error at the inverter needs to be evaluated, it is recommended to also monitor the variable offline, as all other values are only transmitted with a correct connection.

Note: The variable time is not displayed in the monitor.

General

Name	Description
time [datetime]	Last query.
error [bool]	There is a fault at the inverter.
offline [bool]	If the device is not reachable, this value is true.

Energy

Name	Unit	Description
DAY_ENERGY [int]	Wh	Current daily production.
YEAR_ENERGY [int]	Wh	Current annual production.
TOTAL_ENERGY [int]	Wh	Total energy produced by the inverter.
PAC [int]	W	Active power delivered on the AC side.
SAC [int]	VA	Apparent power delivered on the AC side.
IAC [real]	A	Current delivered on the AC side.
UAC [real]	V	Voltage on the AC side.
FAC [real]	Hz	Frequency on the AC side.
IDC [real]	A	Current delivered on the DC side.
UDC [real]	V	Voltage on the DC side.

Status

Name	Description
device_error [bool]	There is an error on the device.
device_error_code [int]	Error code: 0 = No error
devide_status_code [int]	Operating status: 0..6 = Startup 7 = Running 8 = Standby 9 = Bootloading 10 = Error
device_status_reset [bool]	The error must be acknowledged on the device.
status_code [int]	API error code.
status_reason [string]	Error reason in the API as plain text.
status_usermsg [string]	Message text of the API as plain text.
