Memory Cassettes
Built-in flash memory data, such as programs and DM initial-value data, can
be stored on a Memory Cassette (optional) as backup data. In addition, pro-
grams and initial-value data can be easily copied to another CPU Unit using
the Memory Cassette to recreate the same system.
Note
Memory Cassette cannot be used in CP1L-J CPU Unit.
Security
A password registration function is provided for the CPU Unit to prevent unau-
thorized copy of ladder programs. If an attempt is made to read a ladder pro-
gram from a CX-Programmer, access to the program is denied if the password
that is entered does not match the registered password. If incorrect pass-
words are entered for five consecutive attempts, the CPU Unit does not
accept any more passwords for two hours.
