Hi,
How can i ask the holding register 1003 with mbpoll?
@AVsetula said in Reading the ModBus bus with the Patron:
To verify communication with all our Modbus devices, I recommend asking the holding register 1003, which is available for all Modbus devices Unipi and whith contains a unique identifier, according to which the device can also be recognized.
Thank you!

Hi,
I have run apt update && apt upgrade
Now, Patron's service mode and USB stick recovery no longer work.

Ping @Martin-Kudláček
If I want to find out the Patron CPU serial number, is it like this?
cat /sys/devices/soc0/serial_number
...or
cat /sys/devices/soc0/soc_uid
Second question: If this is the serial number of the CPU, is it unique to all devices?
Thank you!

Hi,
EVOK provides incorrect information on Patron:
{
"glob_dev_id": 1,
"last_comm": 0.06514811515808105,
"ver2": "0.1",
"sn": 60,
"circuit": "1",
"model": "M527",
"dev": "neuron", <-- Should be patron
"board_count": 2
}
Could you fix this, please?

Hi,
I have tested to read the Kamstrup 803 meter on the Patron M527 via Modbus.
However, I don't get any results from mbpoll.

Hi,
Otherwise SWUpdate works fine, but the message section shows an error message:

Do you have to worry about that?

Hi @martin_triska,
Thank you for your answer! I got the following answer:
root@residevice:~# lsmod | grep unipi

@tomas_hora said in After upgrading the M503, circuit 1 completely disappeared.:
dmesg | grep UNIPISPI
The device is hundreds of miles away, so I can't watch the LEDs.
dmesg | grep UNIPISPI doesn't output anything.

Hi...again
One more stupid question: How do I reset 1-wire bus with mbpoll?
I mean, how can i "convert" those commands:
./pollmb.py -p 502 -u 1 -f 5 -a 1001 -q 1 -d 1
./pollmb.py -p 502 -u 1 -f 5 -a 1001 -q 1 -d 0
to mbpoll "format". I just don't understand how to read/write coils with mbpoll.
Thank you!

What does that result (3) mean? Its not 0, 1 or 2.
Btw
sudo systemctl stop unipitcp
should be
sudo systemctl stop neurontcp
in Neuron M503...right??

Hi,
That's what we've done with 1-Wire and it works.
I mean, is it possible to do this same 'reset' for Modbus (RTU) itself? We sometimes lose a modbus device.
