More than 1 xSxx on RS485



  • Where I can find a lastes firmware for xS10, folder "latest" is empty
    https://files.unipi.technology/s/public?path=%2FProducts%2FNeuron%2FFirmware%2Flatest

    I have xS10 SN:0000000001 (probably it is the oldest)

    "There was an issue at some older firmwares, that the polarity of speed or parity was different than the desrciption on the case." -how should I set speed and polarity to get connection without reflashing firmware?

    Strange is:
    When I set address on dip switch, RX on xS10 doesn't indicate communication. When address is set to 0 than RX on xS10 indicate communication.

    @wizro_pl and @proceau I am sorry but in some cases of the Neuron xS, there has been an issue that the firmware which we use for testing has been left there instead of reflashing to the production FW.

    If you have the USB-RS485, please use the neuron_extension_FW_tool and reflash it on your own. If not, please let us know on our email and we will reflash the unit for you if you ship it back to us.

    We are sorry for the inconveniences.

    I didn't do it because your application is going crash after put flash button.

    Yesterday, I back to investigate and tried to flash it using fwserial without success (according to this [https://forum.unipi.technology/topic/693/multiple-xs50-on-a-l513-rs485/20](link url)).
    Also, I found out why windows application going crash because programmer do not support exception when the necessary file does not exist (!!) "E-8Di8Ro-0_P-11DiR485-1.bin"

    Here is the result from fwserial:
    root@L203-sn18:/home/pi/unipi-bin# /opt/neuron-bin/fwserial -p /dev/ttyUSB0 -PR
    Boardset: 4 E-8Di8Ro_P-11DiR485 (v1.0)
    Baseboard: 1 E-8Di8Ro (v0.2)

    error opening firmware file "/opt/fw/E-8Di8Ro-0_P-11DiR485-1.bin"
    root@L203-sn18:/home/pi/unipi-bin#

    I've used usbconverter RS485 because I had problem with communication using buildiin RS485 in Neuron.

    I tried with "UniPian-Neuron-OS-2018-03-09.img" and also directly download from https://git.unipi.technology/UniPi/unipi-bin/fw

    There is no file "E-8Di8Ro-0_P-11DiR485-1.bin"

    Here is a search result:

    file "E-8Di8Ro-1_P-11DiR485-1.bin" is not suitable.

    Hello @wizro_pl,
    please, follow these instructions:

    • download the MervisOS v1.7 image from here
    • save it to the SD card
    • put it into your PLC, start it and SSH into it (user: unipi, password: unipi.technology)
    • switch to the root user: sudo bash
    • update the packages: apt update && apt upgrade
    • reboot the unit and SSH into it again and switch to the root user
    • stop the Mervis: systemctl stop mervisrt
    • connect the extension to the RS485 port
    • run the firmware flashing: /opt/unipi-bin/fwserial -p /dev/extcomm/0/0 -PR
    • ... and post the result back here.

    Thank you for your patience,
    Martin

    Hello @Martin-Kudláček @wizro_pl,

    As an addendum, if the above doesn't work, please use these commands before the last step:

    sudo bash
    cd /opt/unipi-bin/fw
    ln -s E-8Di8Ro-1_P-11DiR485-1.bin E-8Di8Ro-0_P-11DiR485-1.bin
    ln -s E-8Di8Ro-1_P-11DiR485-1.rw E-8Di8Ro-0_P-11DiR485-1.rw
    

    and then run the flashing command again, i.e.:

    sudo bash
    /opt/unipi-bin/fwserial -p /dev/extcomm/0/0 -PR
    

    It looks like this is one of the first extension boards we've sent out, and so has an older firmware with a slightly different name, apologies.



  • @martin-kudláček said in More than 1 xSxx on RS485:

    put it into your PLC, start it and SSH into it (user: unipi, password: unipi.technology)

    How to enable SSH ? (probably by defualt is diable)\

    @TomasKnot I did change ealier and got "invalid address" or something like that.



  • ok, I enabled sshd

    I did update & upgrade, reboot.

    Here is your feedback

    I see this version not need "E-8Di8Ro-0_P-11DiR485-1.rw" but it still not proper version.



  • Do you have any sugestion what should we do now?


  • Banned

    Would it be possible to schedule a remote support session over TeamViewer? It seems like it might be the best solution, it's hard to know exactly what has gone wrong in your case.

    I will contact you via a personal message regarding the time and other details.



  • We can do. Yesterday I sent you the private message.



  • When we can do something with that?


  • Banned

    Apologies, I had taken time off for personal reasons for the last two days. I will be here over the next two weeks every day.
