PRECAUTIONS
• Turn off the power to the PLC before attaching or detaching the memory cassette. If the memory cassette is attached or detached
while the PLC's power is on, the data in the memory may be destroyed, or the memory cassette may be damaged.
• Do not disassemble or modify the PLC.
Doing so may cause fire, equipment failures, or malfunctions.
For repair, contact your local Mitsubishi Electric representative.

The memory cassette can be installed at the main unit, and when installed, the memory cassette's internal
program is used in place of the internal EEPROM memory. The loader function transfers (reads and writes)
programs between the memory cassette and the internal EEPROM.
