I’m currently managing over 50 PLCs running Codesys version 3.5.18.60. At seemingly random intervals, some of these devices experience a failure where:
All persistent variables are lost.
Attempting to log in results in the message:
“The application does not exist on device. Do you want to create it and proceed with download?”
The log shows:
“Loading retain-data/bootproject failed.”
From what I’ve gathered, this may be due to a corrupted persistent data file, but I’m not entirely sure how to confirm or resolve this issue.
If anyone has encountered something similar or has suggestions for troubleshooting or preventing this, I would greatly appreciate your input.
