Hello Roy,
after updating it from 2019.X to 2020.0 try executing a factor 1 Reset. Hold reset Button and power down.
What happens after the Boot?
please have a look at
“df -h”
and attach the logs from/var/log/
so we can do further diagnostics. kind regards,
Oliver
Hello Roy,
so is it working now? looks like PLCnext started fine? kind regads,
Oliver
Hello Oliver, Yes, resetting the PLCNext fixed it, I forgot to mention that. Many Thanks! Roy
