    • RE: M525 stopped working

      Hi @martin_triska,

      Yes, that sums up the situation well, so I'll write to [email protected] for replacement request.

      Many thanks,

    • RE: M525 stopped working

      Hi @martin_triska,

      I confirm the solution is stable over >50 days when using port 1.3 :

      uptime.jpeg

      ... but not with port 1.1, where serial communications crashes < 10 days !
      If you did not find a software issue related to port RS485-1.1 on Axon M525, there should be a hardware issue with my PLC !

      I have bought this PLC because I need 3 RS485 ports, so using port 1.3 over 1.1 is not a solution...

      Can you please replace this unit ?
      Many thanks in advance and kind regards,

      Pascal

      Hi @martin_triska,

      1. I did a reflash (USB method) of my M525 with latest Mervis OS image (2.3.0.10), firmwares are already up-to-date:
      unipi@M525-sn8:~$ sudo /opt/unipi/tools/fwspi -i 0
      Boardset:     0 B-1000                         (v1.0)
      Baseboard:    0 B-1000                         (v2.0)
      Firmware: v5.50
      unipi@M525-sn8:~$ sudo /opt/unipi/tools/fwspi -i 1
      Boardset:    19 E-4Ai4Ao_U-R485Di4Ro5          (v1.0)
      Baseboard:   11 E-4Ai4Ao                       (v1.0)
      Firmware: v5.50
      
      1. From what I've seen after serial communications "crashes", I did not see anymore an i2c-0 error in demsg, so I am not sure this is correlated.

      2. Yes: it is a standard Mervis OS image + 2 pythons scripts running as daemons with pymodbus client over ModbusTCP, so no serial communications there.

      3. Yes: I am using shielded cable specific for RS485, the bus is properly terminated at each end. Cable shield is properly grounded at PLC side and also to PLC itself. Environment is stable and, so long the issue is not occurring, communication is working perfectly.
        With the increase of Max telegram duration to 300ms, there is absolutely no error during multiple days:

      PLC_status.JPG

      It seems most likely a driver or Mervis runtime issue related to M525 model and port 1.1 !?
      As I said, I never had the issue when using port 1.3 instead of port 1.1
      I have also another RS485 bus on port 2.1 and no issue either.
      This issue also never occurred with port 1.1 on my previous M505 PLC

      If you want to try reproduce the issue, you need 3 Inepro PRO380 meters and read constantly multiple values from them like power, energy, voltage.
      In my case, the maximum uptime before a crash is about 10 days.

      I can use port 1.3 in the meantime, but I will need the 3rd RS485 port later for my project...
      But let's check again if it is really stable with port 1.3 over >10 days !

      Many thanks in advance and kind regards

    • RE: M525 stopped working

      Hi @tomas_hora, issue occured again again with port 1.1 and new settings (Max telegram duration to 300ms + added a 5ms pause between telegrams.)
      A simple PLC reboot (from Debian OS) was enough to regain data acquisition from the 3 Inepro PRO380 meters.

      I do not understand why problem never occured when using port 1.3 of same PLC, nor with my previous M505.
      What is the difference between ports 1.1 and 1.3 ?
      If same hardware, could it be a hardware issue with port 1.1 on my M525?

    • RE: M525 stopped working

      Hi @tomas_hora,

      I have increased Max telegram duration to 300ms + added a 5ms pause between telegrams.

      I have also update my M525 to latest Axon runtime (2.3.0.8) with latest firmwares/drivers.

      I will let you know if issue occurs again.
      Many thanks and kind regards.

      The command was run while serial communication timeouts, but output is the same after a PLC restart.

    • RE: M525 stopped working

      Hi @tomas_hora,

      Issue occurred again with port RS485-1.1

      This time, a simple reboot (from Debian OS) was enough to regain data acquisition from the 3 Inepro PRO380 meters.

      Port configuration:

      serial_port_config.jpg

      cat /run/unipi/io_group1/uart_config
      9bd
      

      Data captured after communication stops working:

    • RE: M525 stopped working

      Hi @tomas_hora,

      The issue occured again with port RS485-1.1 just after 5 days of uptime, but sorry, I was not capturing serial data before the "crash". This is quite difficult to do: it means leave IDE open in debugging mode during up to 10 days and be able to select all the output (> 50 millions packets) !? Is there any better why to archieve that ?

      Workaround is to redeploy the solution from IDE (cold restart), and serial communication works again immedately.
      The issue is definitvely not on the RS485 bus or Inepro devices.

      I had this issue now 3 times with the port 1.1 on the Axon M525, but not with port 1.3, nor with an Axon M505.
      Since a solution deploy does not reboot the Debian OS of the PLC, the issue should be somewhere in the Mervis runtime !?

      The first time the issue occured, I did a complete reboot of the PLC, but this is not a workaround... as if a counter in the Mervis runtime is not reseted properly like a solution deploy with cold restart.

      Many thanks in advance for your help and kind regards.

      Hi @Martin-Kudláček,

      No issue after 15 days of uptime using port RS485-1.3 :

      0_1589308492689_8fae0eef-f7df-4118-aa5a-82b5300d6a28-image.png

      I switch now back to port RS485-1.1 to check if issue occurs again after 10 days...

      Hi @Martin-Kudláček,

      A simple "sudo reboot" of the PLC has solved the issue and communication works again error free:

      0_1587828876138_421e417e-cd95-4f47-9c5d-16898c910ff4-image.png

      Current serial port is RS485-1.1, I will try if same issue occurs after 10 days if using port RS485-1.3 ...
