16-4 Security Functions
The Security function can be used with any model of CP2E CPU Unit.
With the CX-Programmer, it is possible to set read protection using a password for the whole ladder
program.
When the program is read-protected using a password, it is not possible to display or edit any of the lad-
der programs using the CX-Programmer unless the password is entered in the Disable Password Dia-
log Box from the CX-Programmer.
This enables improved security for PLC data in equipment.
z Read Protection Using Extended Passwords
Extend protection with UM read protection to ensure better protection for your design assets. Also, if
the password is incorrect five times in a row, a password cannot be entered for two hours.
