Read/Write-protection Using Passwords
Both read and write access to the user program area can be blocked from the
CX-Programmer. Protecting the program will prevent unauthorized copying of
the program and loss of intellectual property. A password is set for program
protection from a Programming Device and access is prevented to the whole
program.
1. If you forget the password, the program within the PLC cannot be trans-
ferred to the computer. Make a note of the password, and store it in a safe
place.
2. If you forget the password, programs cannot be transferred from the com-
puter to the PLC. Programs can be transferred from the computer to the
PLC even if the password protection has not been released.
1. Register a password either online or offline as follows:
a) Select the PLC and select Properties from the View Menu.
b) Select Protection from the PLC Properties Dialog Box and input the
password.
2. Set password protection online as follows:
a) Select PLC, Protection, and then Set. The Protection Setting Dialog
Box will be displayed.
b) Click the OK button.
Note For CS/CJ-series CPU Units Ver. 2.0 or later, read-protection can be set not
only for the entire program, but also for specific tasks. For details, refer to
Read Protection for Individual Tasks Using Passwords under 1-4-2 Improved
Read Protection Using Passwords in the CS Series PLC Operation Manual or
the CJ Series PLC Operation Manual.
With a CS1-H, CJ1-H, CJ1M, or CS1D CPU Unit, the dates the program and
parameters were created can be confirmed by checking the contents of A090
to A097.
