@roberts_lando Sorry, dont know.

Hello @mmcreativ,
there is no card inside of the PLC. It looks like the M205 isn't properly flashed or there is some HW error. Please, let's continue about the detail over email [email protected]. Send us an email with this information:

serial number of the PLC first photo or better yet a video of the top cover of the PLC with clear indication of the LED

Thank you and have a nice day,
Martin

Hello,

check the list some of the available DALI power supplies on the market below:

Tridonic - Dali PS1, Dali PS2, Dali PS3 Recom - RELV4-16 Foxtron - DALIpwr Lunatone - Dali PS, Dali PS2, Dali PS128, etc...

Foxtorn is commnonly available in Czech since its a company located in Prague.

If there are some missing modules, you need to compile it.
On Axon (or generaly any arm64 platform) do:

apt install build-essential git git clone https://git.unipi.technology/UniPi/axon-linux.git make unipi-axon_defconfig

Now you can change kernel configuration to desired state

make menuconfig

Compile new modules

make modules

You can compile on amd64 platform using CROSS_COMPILE

make unipi-axon_defconfig CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 make menuconfig CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 make modules CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64

Hello @ayone0518,
you need to pull 32bit data, so you have to define element which spans over 2 registers. This is done via the Multibyte Length property, which you have to set to 4 (4 bytes = 32 bits)

If it is possible, I would suggest to turn the communication around. Make the Mervis a Modbus Slave (server) and the Weintek Modbus Master. Configuration in the Mervis will be much easier. Try following this tutorial: https://kb.unipi.technology/en:sw:01-mervis:setting-modbus-server-hidden and here you can see how to set it against Weintek: https://kb.unipi.technology/en:sw:01-mervis:weintek-ip-series-hidden#setting_up_the_unipi_for_sharing_temperature_and_relay_output

Hello @tomas_hora ,
thank you for your answer. that is the one I wanted to know.

I managed to get what I need by compiling a new (hopefully) compatible set of modules and installing by hands only the needed ones. Here are the steps I followed, executed directly on the AXON as root:

v=$(uname -r) cd /usr/src wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-$v.tar.xz tar xf linux-$v.tar.xz cd linux-$v gzip -dc /proc/config.gz > .config apt install libncurses5-dev bc # Customize the kernel to your needs. In my case I enabled the # snd-usb-audio module that, in cascade, enabled other sound stuff. make menuconfig # Build and install *only* the new modules. make modules mkdir -p /lib/modules/$v/kernel/sound/usb cp sound/usb/*.ko /lib/modules/$v/kernel/sound/usb/ cp sound/core/snd-*.ko /lib/modules/$v/kernel/sound/core/ depmod # Not strictly needed, but forbidding future axon-kernel upgrades # could avoid potential hard-to-debug problems. apt-mark hold axon-kernel

@heikkim Hello, to enable wifi you should enable the interface in /boot/boot.cmd by commenting the followin lines (add a # at the beginning)

fdt set /soc/mmc@01c10000/bcrmf@1 status "disabled"
fdt set /soc/mmc@01c10000 status "disabled"

Then run mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr and reboot.

Does it work?

@leif-edh That is doable but you would need to setup WiFi access point on one of those M205 (find a tutorial for hostapd), and enable bridging (available in bridge-utils package).

If you won't use static IP addresses, you would have to also setup a DHCP server on the WLAN and eth, br interfaces.

This tutorial might help you a bit: https://www.cyberciti.biz/faq/debian-ubuntu-linux-setting-wireless-access-point/

Another option is to put a router AP in the middle of it all.

Also, note that the internal wifi antenna does not have much gain and is inside an aluminum box so the range is limited...

Hello @raubucs,
there is no such function, you have to exchange the cables at the connector side.

Best regards,
Martin

Thank you very much for taking the time to investigate.
Problem is fixed as it appears that it was some test scripts still running in the background and thus blocking access to the daughter board.

@matt The standard wpa_supplicant tools works well.

Hi @PhilesG!

That's good to hear, though a bit concerning that it doesn't work with all flash drives. I'm not sure what we can do about that, but we'll have a look at it again.

The size limit in the web interface is unfortunately inserted quite deep into the system; essentially it's the amount of memory-mapped drive space that is reserved for holding the file sent over the network. Which is also why the flash drive method works, as the file is instead stored on the drive.

At any rate - glad you managed to get it to work!

Hello,

No noise. No light. No luck.
Only the green led turned on.

So I suppose I have to contact support.

Thanks for your help and quick answers !

Pozoruji stejné chování na Neuronu S105. Skutečně nepomůže ani vypnutí napájení 1-W sběrnice pomocí proměnné OW_off(případně fyzické odpojení a připojení čidel). Komunikace se rozeběhne až po vypnutí napájení neuronu!

Takovéto chování významně snižuje použitelnost PLC a to jsem chtěl zkusit nahradit Neuron Axonem...už vidím, že to není řešení.

Nevím jak dál...master 1-W sběrnice je připojen na I2C...tam bych odhadoval, že bude chyba. I2C se nedokáže vzpamatovat po určitém množství chyb na sběrnici.

Žádám tým unipi o simulaci stavu zarušení 1-W sběrnice a možnost jejího zotavení.

@tomasknot This is really nice! Thanks so much I will adopt this approach.

Oh I have missed that line, I was looking for "static" word in that file. Thanks :)
