Hi to All,
The hardware of my project is consisting with a raspberry pi3 b+ and a pico ups 3.0. As suggested in many thread the grateful shutdown is managed by the ups. A simple codesys application manage some automations in my home.
When the power is down the ups runs the "sudo shutdown" and all persistent variables keep their values. The system freezes when voltage fluctuations occur.
Thank You for help me,
this was here:
but not sure if you see the same issue.
I would recommend to start the plc manually by commend to get more information:
stop the runtime
sudo /etc/init.d/codesyscontrol stop
start the plc runtime manually
sudo /opt/codesys/bin/codesyscontrol.bin -d /etc/CODESYSControl.cfg
tail -f /tmp/codesyscontrol.log
What does mean the system freeze... Linux OS or the CODESYS Runtime?
The codesys runtime. The variables declared as PERSISTENT RETAIN loose their values.
Did'nt we discuss this a few month ago?
Think the shutdown of the network adapter caused the problem
Not with me...
What do You mean with "shutdown of the network adapter"?
I don't think that the problem is the same to the previous topic.
So, is there a possibility to export these variables to a usb memory?
Thank you and happy new year
