USB memory device operation error
• An operation command was given during the USB memory device operation.
• A copy operation (writing) was performed while the PLC function was in the RUN state.
• A copy operation was attempted for a password locked project.
• Check if the USB memory device is operating.
• Check if the PLC function is in the RUN state.
• Check if the project data is locked with a password.
• Perform the operation after the USB memory device operation is completed.
• Stop the PLC function. (Refer to
• Unlock the password of the project data using FR Configurator2. (Refer to the Instruction Manuals of FR
Configurator2 and GX Works2.)
