Keyword protection of the MELSEC-F series

I have registered a keyword for protecting the MELSEC-F series. How I can forcibly reset the protection if I forget the keyword?

Answer

The keyword protection cannot be forcibly reset.
Since only the keyword that has been registered by the user is acceptable, please take measures to ensure the keyword is not lost.

If deleting data does not cause any problem, all programs and parameters including the keyword setting, can be cleared by executing the clear PLC memory function from the peripheral connected.
