(2f) Inverter control via Modbus
If this option is activated, the inverters can be controlled via Modbus.
The "Limit Control" selection field is displayed.
Inverter control includes the following functions:
- On/off
- Power reduction
- Setting a constant power factor (cos phi)
- Setting a constant reactive power
(3) rtu
Data output via Modbus RTU
(3a) Baud rate
Used to enter the baud rate
(3b) Parity
Selection field for entering the parity
(3c) String Control address offset
Offset value used to assign addresses to Fronius String Controls via Modbus.
For further details, see the section entitled "Modbus Device ID for Fronius String
Controls."
Sunspec model type
Used to select the data type of data models for inverters.
(3d) float
Display as floating-point numbers
SunSpec Inverter model I111, I112 or I113
(3e) int+SF
Display as integers with scaling factors
SunSpec Inverter model I101, I102 or I103
IMPORTANT! Since the different models have different numbers on registers, the
register addresses of all the subsequent models also change when the data type
is changed.
(3f) Demo mode
The demo mode is used to implement and validate a Modbus master. It enables
you to read inverter, energy counter, and String Control data without actually con-
necting or activating a device. The same data is always sent back for all the reg-
isters.
