NOTE! If there is a Modbus energy counter (e.g. Fronius Smart Meter) configured
under Settings/Counter on the system, it will not be possible to use the "RTU" set-
ting.
In this case, data output via Modbus will be deactivated automatically upon selec-
tion of "RTU." This change will only be visible once the Datamanager web page
has been reloaded.
Any energy counter connected to the Datamanager via RS485 can also be read
by Modbus TCP via the corresponding SunSpec models. The Modbus ID for the
counter is 240.
(1) off
No data output via Modbus
(2) tcp
Data output via Modbus TCP
(2a) Modbus port
Number of the TCP port which must be used for Modbus communication.
(2b) 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 and energy counters.
(2c) float
Display as floating-point numbers
SunSpec Inverter model I111, I112 or I113
SunSpec Meter model M211, M212 or M213
(2d) 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 on registers, the
register addresses of all the subsequent models also change when the data type
is changed.
(2e) Demo mode
The demo mode is used to implement or 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.
