Hi,
First of all, I woulf like to thanks in
advance for any
help or for indication where to get the
information
needed.
I am looking for frameworks to test a
building iot
application, so I started a PoC with Kura some
days ago, testing
with a fire panel.
At the first installation of Kura (using
3.1.0-M1), I
could communicate with a panel through
MODBUS/TCP - around 2 or 3
weeks ago.
But last week I did a new fresh
installation (target hw is
a rasperry 3), and now I am getting the
following message in the
log:
2017-09-01 13:34:52,982
[DefaultQuartzScheduler_Worker-5] ERROR
o.e.k.i.w.a.WireAsset -
ModbusDriverMessages.errorRetrievingUnitId
It seems that the driver is looking for
the slave Id but
do not get it. I have seen in the kura´s forum
that up to some
version, the modbus driver had only rtu over
tcp protocol
available, but as I have had success at the
first installation to
monitor the equipment, I presume with
modbus/tcp, then I guess the
error now is looking to be related with modbus
rtu over
tcp.
Everything else is working nicely and I
tried with 3
differents simulators, and with the fire
panel: modbus pal (as
showed in the kura docs), simple modbus
(trying option tcp and rtu
over tcp), and ananas. All of them give the
same error.
Also, in a second hardware target
(raspberry, too), I
installed Kura 3.0.0 to see if it was some
compatibility issue with
3.1.0-M1, but got the same error.
I have used the ECF modbus driver
available in the
marketplace, for my PoC. In next step I intend
to develop a driver
with specific equipment needs.
And, I would like to congratulate
everyone working in the
framework, and the contributors. It is a very
good
project.
Regards,
Marcelo
