Features and Main Functions Section 1-1
(2) By using the serial PLC Links, a maximum of 10 words of data per CPU
Unit can be shared independently of the program among a maximum of
nine CPU Units (CP1L-EL/EM/CP1H/CJ1M) using RS-422A/485 Option
Boards.
No-battery Operation
Programs, the PLC Setup, and other data can be automatically saved to the CPU
Unit's built-in flash memory. Moreover, DM Area data can be saved to the flash
memory and then used as initial data when the power is turned ON.
This allows programs and initial values (such as recipe setup data) in the DM Area
to be saved in the CPU Unit without the need to maintain a backup battery.
Memory Cassettes
Built-in flash memory data, such as programs and DM initial-value data, can
be stored in 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.
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
passwords are entered for five consecutive attempts, the CPU Unit does not
accept any more passwords for two hours.
Read Protection Using
Extended Passwords With unit version 1.1 or later and CX-Programmer version 9.6 or higher, you
can extend protection with UM read protection and task read protection to
ensure better protection for your design assets.
