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.
