8-7-1 Read Protection
Overview
It is possible to read-protect individual program tasks (called task read protec-
tion) or the entire user program (called UM read protection).
Read protection prevents anyone from displaying or editing the read-protected
set of tasks or entire user program from CX-Programmer without inputting the
correct password. If the password is input incorrectly five times consecutively,
password input will be disabled for two hours, providing even better security
for PLC data.
Read Protection Using
Extended Passwords With unit version 1.1 or later and CX-Programmer version 9.6 or higher, you
can extend protection with UM read protection and task read protection to
ensure better protection for your design assets.
