How to add xS40 to Neuron L203 using custom software

[unix]

Hi
this day after a reboot i have the same error message and the link from S103G to xs50 not working only one short blink from the modbus rx/tx

reinstall evok and fresh image not working.

I have this exact same issue as "unix", both with the master branch and 2.0.6. Anyone that came up with a solution?

[TomasKnot]

Hi @alydersen!

Do you also have the xS50 and S103G models? The error is simply a generic error indicating that no data from the device is available to EVOK in its cache.

It can be caused by wrong parity, bitcount or address settings, as well as potentially any other issues which break the communication.

By far the most crucial LED indicator is the RX LED light on the master Neuron unit - does it light at all? If not it means that no response has been sent on the bus, which means that there is no data received on the underlying hardware - much less EVOK itself.

Please see below, apologies

[TomasKnot]

@alydersen

It looks like there has been a recent bug in EVOK which caused the hardware definitions to be parsed incorrectly. What I said above does stand, but the error is a software bug on our part.

You will need to download the release 2.0.7 in order to fix the problems you are seeing. The source of the error is a missing condition which causes UART hw_definitions to break, though only some of the time.

[alydersen]

Thanks @TomasKnot - will try it out

[alydersen]

@TomasKnot That did it - thanks again

[Boy Lenssen]

@tomasknot Sorry for the late response! I had a different project that needed my attention.

The RX light of the extension is constant on.
the TX light of the Neuron flashes. The RX light doesn't do anything.

Hope we can figure this out, as I got told we need to get this working soon, hopefully this week...

This is the config:

allow_register_access = False 			; Optional, False default
scan_frequency = 10						; Optional, 10 default
scan_enabled = True 					; Optional, True default

; Devices sharing a port use the port settings of the first device on that port (baud rate, parity, stopbits)
; !!!Note that device_name has to match a filename in the /etc/hw_definitions directory!!! See /etc/hw_definitions/DOMAT MMIO.yaml for an example

parity = N								; Optional, NEEDS UNIPI IMAGE TO WORK! USE API TO CONFIGURE UART MANUALLY IF USING STANDARD RASPBIAN

This is the config on the xS40:

What can I do to help troubleshoot further?

[TomasKnot]

@Boy-Lenssen
That definitely looks like a problem with UART settings, as no RX on the Neuron indicates that there is no response from the extension, not even an error response (which is what occurs when e.g. reading wrong registers or issuing invalid commands).

Could you try using the latest version of EVOK? It is possible that some recent changes will help fix the problems you are seeing.

[Boy Lenssen]

@tomasknot I'm sorry, I'm already running 2.0.7. Forgot to mention.

still getting this:

[Boy Lenssen]

@TomasKnot do you have any pointers for me? I really need to get this working for a customer :\

Any way I can supply you with more info to test it?

Maybe you can create an SD card image file of the configuration that works for you so I can try it out?

[Martin Kudláček]

@boy-lenssen Hello, I am terribly sorry for a delay on our side. Tommorow morning I will reproduce your setup (L203 with xS40) and supply you with the working image. Thank you for you patience.

Martin

[Martin Kudláček]

Hello @Boy-Lenssen ,
I was able to get a working connection from UniPi Neuron L503 to xS40.

Here you can see general wiring, the white wires are for RS485.

Here you can see the DIP switches on the xS40. As you can see, the Modbus address is set to 5, speed to 19200 and no parity. The unit is also set as a last one on the RS485 bus

And here you can see the working setup. I setted some ROs on the xS40 via the web interface

This is the configuration file I used:

[Boy Lenssen]

still the Rx on the Extension light is on and I get the same error as I posted before when running sudo python /opt/evok/evok.py

@martin-kudláček said in How to add xS40 to Neuron L203 using custom software:

The unit is also set as a last one on the RS485 bus

do I need to do something for this? I'm sorry, I'm quite a noob on this.

[Martin Kudláček]

@boy-lenssen Just to be absolutely sure - did you:

• set the DIP switches exactly the same as on the photo
• replaced the /etc/evok.conf with the one I sent you
• restarted evok with sudo systemctl restart evok

The DIP switches need to be set while the extension is OFF and then turned ON.

Thanks,
Martin

[Boy Lenssen]

@Martin-Kudláček I created a video of when I turn on the power.

I replaced the evok.conf exactly with what you posted.
I use the SD card I always use and updated it last week to 2.0.7.

Here is the video: https://youtu.be/4_BAgph3VSA

and this is the error I see in /var/log/evok.log:

Hello @Boy-Lenssen,
here is the image: www.uschovna.cz/zasilka/ALFLHCVAFG743SWB-4SR

Just save it on at least 8GB SD card with Win32DiskImager. The IP will be acquired via DHCP.

[Boy Lenssen]

@martin-kudláček will do, it is downloading, but takes a couple of hours, it says...

btw;
I tried with a new image, Raspbian stretch lite, installed evok and set up the evok.conf for the extension. Same issue... No cached value of register 1018 on unit 5 - read error

@Martin-Kudláček I tried your image and gives exactly the same issue.

What now? Am I missing some hardware configuration?

[Boy Lenssen]

Maybe it has something to do with the xS40 or my Neuron? Maybe I could try a different Neuron. Unable to swap the extension unit, as I have only one.

@martin-kudláček said in How to add xS40 to Neuron L203 using custom software:

Hello @Boy-Lenssen,
here is the image: www.uschovna.cz/zasilka/ALFLHCVAFG743SWB-4SR

Just save it on at least 8GB SD card with Win32DiskImager. The IP will be acquired via DHCP.

btw, the IP doesn't matter, right? I didn't configure an ethernet connection for your image as it is all local. Just needed to check if the light go on.

I also just use WiFi instead of cabled connection on this device.
