In a production environment we are experiencing some issues where the PLC gets completely stuck after a while and does not respond to actions anymore. In the Codesys development enivornment we can see the values being updatet, but as soon as we log off we are unable to make a connection to the PLC anymore. The PLC doesn't respond to start/stop actions anymore either, as well as the webvisu is unreachable. The only resort is to reboot the computer.
Inspecting this inconvience, shows the following error in the PLC log. Can anyone enlighten what this means, what could cause this and/or what we could do to debug this?
Thanks in advance!
