Possible remedy
Use one of the following methods.
• Toggle the USE/NO USE switch for the
CPU Unit with the error to NO USE and
back to USE and then press the initializa-
tion button.
• If the automatic recovery setting has been
enabled in the PLC Setup, use the auto-
matic recovery function to restart.
• If operation still cannot be recovered,
replace the CPU Unit.
See below for specific bits.
Use one of the following methods
If operation has switched from Duplex to
Simplex Mode:
• Toggle the USE/NO USE switch for the
CPU Unit with the error to NO USE and
back to USE and then press the initializa-
tion button.
• If the automatic recovery setting has been
enabled in the PLC Setup, use the auto-
matic recovery function to restart.
• If operation still cannot be recovered,
replace the CPU Unit.
If the error occurs in Simplex Mode:
• Retransfer the program and parameters.
• If operation still cannot be recovered,
replace the CPU Unit.
Make sure that the Memory Card is installed
properly and that the correct file is on the
Card.
A hardware error has occurred in the CPU
Unit. Replace the CPU Unit.
• If a DIP switch has been changed by mis-
take, reset the settings to the original set-
tings, and then restart the Unit.
• To change to a different model by using
Duplex CPU compatible setting, perform
Memory All Clear.
Check the indicators on the Inner Boards
and refer to the operation manual for the
Inner Board.
