Program Protection
Section 6-6
CPU Unit DIP Switch
Confirming the User Program Date
The dates the program and parameters were created can be confirmed by
checking the contents of A90 to A97.
Auxiliary Area Words
Write-protection
Using Passwords
The program (or selected tasks) can also be write-protected if the write pro-
tection option is selected from the CX-Programmer when a password is being
registered for the entire program or those selected tasks. The write protection
setting can prevent unauthorized or accidental overwriting of the program.
Note
1.
If the selected tasks are write-protected by selecting this option when reg-
istering a password, only the tasks (program) that are password-protected
will be protected from overwriting. It will still be possible to overwrite other
tasks with operations such as online editing and task downloading.
