Modbus Settings

General

From your web browser, you can use the Fronius Datamanager 2.0 website to apply the
Modbus connection settings which cannot be accessed via the Modbus protocol.
Additional In- For additional information on the Modbus function, please see the following Operating In-
formation on the structions:
Modbus Function
Data Output via "Data output via Modbus" "off"
Modbus If the data output via Modbus is deactivated, control commands sent to the inverter via
Modbus are reset, e.g., no power reduction or no reactive power specification.
"Data output via Modbus" "tcp"
If the data output via Modbus is deactivated, control commands sent to the inverter via
Modbus are reset, e.g., no power reduction or no reactive power specification.
"Modbus port" field – number of the TCP port which must be used for Modbus commu-
nication. Presetting: 502. Port 80 cannot be used for this purpose.
"String Control address offset" field – offset value for addressing Fronius String Con-
trols via Modbus.
"Sunspec Model Type" – used to select the data type of data models for inverters and
energy meters.
"float" – display as floating-point numbers.
SunSpec Inverter model I111, I112, or I113
SunSpec Meter model M211, M212, or M213
"int+SF" – display as integers with scaling factors
SunSpec Inverter model I101, I102, or I103
SunSpec Meter model M201, M202, or M203
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.
