I have some trouble with a CJ2M-CPU33. My client did a backup to memory card earlier today, and after this we did some changes through remote link. Now the client wanted to restore the previous backup to the PLC and has done so, but the system would not function correctly. After going online on the PLC it seems like the PLC is stuck in "Stop/Programming Mode". When trying to change to "Monitor" or "Run" mode a dialog comes up containing the following message: "Failed to change the operating mode. The operating mode may be still changing in the PLC."
- All the dip switches are set to off after restoring backup
- The PLC has been rebooted
- I have downloaded the application again through CX-programmer
- Verified that the PLC is set to start up in "Monitor mode"
But nothing helps. The same message comes up when trying to change the operating mode.
Hoping anyone can help to resolve this issue as it is very critical for us and the client.
In advance, thanks for any tips or help received.
