When a password is being registered for the entire user program or
selected tasks, the creation of backup program files (.OBJ files) can be
enabled/disabled with an option setting.
Backup program files (.OBJ files) cannot be
created with file memory operations.
Operating Procedure
1. When registering a password in the UM read protection password Box or
Task read protection Box, select the Prohibit from saving into a protected
memory card Option.
2. Either select PLC - Transfer - To PLC to transfer the program or select
PLC - Protection - Set Password and click the OK button.
Usage
This option can be used to prevent the program from being transferred out of
the PLC using the password.
Note 1. The simple backup operation can still be performed when the creation of
program files is prohibited, but the backup program file (BACKUP.OBJ) will
not be created.
2. The program can be copied when program read protection is not enabled.
3. The setting to enable/disable creating file memory program files will not
take effect unless the program is transferred to the CPU Unit. Always trans-
fer the program after changing this setting.
With the pre-Ver. 2.0 CS/CJ-series CPU Units, the CPU Unit's user program
memory (UM) can be write-protected by turning ON pin 1 of the CPU Unit's
DIP switch. In this case, it is possible to overwrite the user program memory
by turning OFF pin 1.
