Read Protection for Individual Tasks Using Passwords
Overview
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.
