Program Protection

Read Protection for Individual Tasks Using Passwords

Overview
Task Read Protection
3. If an incorrect password is input five times consecutively, read protection
will not be released even if the correct password is input on the sixth at-
tempt and displaying and editing the entire user program or the specified
tasks will be disabled for two hours.
It is possible to read-protect individual program tasks (referred to as "task
read protection" below) or the entire PLC. The same password controls
access to all of the read-protected tasks.
Task read protection prevents anyone from displaying or editing the read-pro-
tected set of tasks from CX-Programmer without inputting the correct pass-
word. In this case, the entire program can be uploaded, but the read-protected
tasks cannot be displayed or edited without inputting the correct password.
Tasks that are not read-protected can be displayed, edited, or modified with
online editing.
Note Task read protection cannot be set if UM read protection is already set. How-
ever, it is possible to set UM read protection after task read protection has
been set.
CX-Programmer
Set a password for particular tasks in the project directory.
Password?
Those tasks cannot be displayed without inputting the password.
