Every three minutes the eWON reboots due to a watchdog in process (opcuacom)
Is there a fix to this?
Hi Ben,
Can you send us a backup.tar file from eBuddy with the support files included?

I just reformatted the device. I did grab this picture before then.
When I unplug the ethernet cable going to my HMI, it does not reboot.
I downgraded the firmware to 13.3 and this seamed to stop the constant reboots.
Let me know if you need any more information.
It might’ve been the re-flashing of the firmware that fixed it, but it’s hard to say what might have been causing the problem without being able to get a backup of the device before.
i have a similar error when i try to write the value of a string to my S7 plc, and in the plc the address of the tag is not present, if i disconnect the cable, the ewon stop rebooting…
There was a fix in firmware 14.2 for watchdog reboots. Have you tried updating to 14.2?
Yes, the problem remain… it is not a watchdog problem.
if you want to replicate:
define a string tag s7 and in the io address field write an address of a db that is not loaded in the plc
in the basic script ini section try to write a string in this tag; run the script;
the ewon reboot… and restart… and reboot
but… if you disconnect the cable between the ewon and the plc… ewon stop rebooting
unfortunately i can’t, but it’s very easy to reproduce te problem as described in my previous post
I’m not sure if this is a bug or expected behavior as you’re intentionally trying to write to an address that doesn’t exist, but I’ll look into it.
if i try to write a real, bool , int, i have no reboot; if i try to write a string, i have the reboot, for me it’s a bug
So I’m going to escalate this case so the developers can take a look at it.
@iw3bti1, you have an account with mysupport.hms.se and your case will go through the EU office, so you may get an email from them.
@BenKropidlowski, can you please provide a company email, or company name/address to open the case under?
Thanks!
