" 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
" Data output via Modbus " set to " RTU "
If there is a Modbus energy meter (e.g., Fronius Smart Meter) configured under Settings/
Meter in the system, it will not be possible to use the "RTU" setting.
In this case, data output via Modbus will be deactivated automatically upon selection of
"RTU." This change will only be visible once the website has been reloaded.
Any energy meter connected via RS-485 can also be read by Modbus TCP via the cor-
responding SunSpec models. The Modbus ID for the meter is 240.
" Interface " field – Modbus interface 0 (rtu0 | default) or Modbus interface 1 (rtu1) can be
selected here.
" String Control address offset " field – offset value for addressing Fronius String Con-
trols via Modbus. For further details, see "Modbus Device ID for Fronius String Controls"
section.
" Sunspec Model Type " – used to select the data model data type for inverters
" float " – display as floating-point numbers
SunSpec Inverter model I111, I112, or I113
"
int+SF " – display as integers with scaling factors
SunSpec Inverter model I101, I102, or I103
IMPORTANT!
Since the different models have different numbers of registers, the register ad-
dresses of all the subsequent models also change when the data type is changed.
" Demo mode " – the demo mode is used to implement or validate a Modbus master. It
enables you to read inverter, energy meter, and String Control data without actually con-
necting or activating a device. The same data is always sent back for all the registers.
" Inverter control via Modbus "
If this option is activated, the inverters can be controlled via Modbus. Inverter control in-
cludes the following functions:
-
On/off
- Power reduction
- Setting a constant power factor (cos phi)
- Setting a constant reactive power
" Control priorities "
Used to specify which service is given priority by the inverter control unit.
1 = highest priority, 3 = lowest priority
The control priorities can only be changed under the "
UC EDITOR " menu item.
Limit Control The "Limit Control" option is only available for the TCP transmission protocols.
It is used to block inverter control commands from unauthorized users by only permitting
control for specific devices.
