Features and Main Functions
Section 1-1
• Displays the progress of transfers between the CPU Unit and Memory
Cassette.
• Displays changes in values when using the analog control.
• Displays user-defined codes from special display instructions in the lad-
der program.
No-battery Operation
(All Models)
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 bat-
tery.
Memory Cassettes
(All Models)
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.
Security (All Models)
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.
